Now two of the other people in the Ellison conference room meeting, also later leave and show up at a small client/server startup responsible for something called "commerce server". We are brought in as consultants because they want to do payment transactions on their server; the startup had also invented this technology called "SSL" they wanted to use; the result is now frequently referred to as "electronic commerce".
As part of doing payment transactions ... we had to deploy something
called a "payment gateway" (periodically refer to as the original SOA)
that sat between the internet and the payment networks. misc. past
posts mentioning payment gateway

Also as part of mapping SSL technology to payment transaction business
processes, we had to do audits and walk-thrus of these new businesses
called Certification Authorities ... as well as a number of
assumptions about deployments. It turns out that almost immediately,
several of the assumptions were violated ... contributing to a
significant percentage of current security problems. Some past posts

the original JES2 networking source still had "TUCC" identifier in cols
68-71 (from the installation where the code had been originally
developed). it had hack that it defined network nodes in the 255 entry
psuedo-device table (used to define psuedo unit record devices)
... which typically would have possibly 160-190 empty entries that could
be used. the implementation intermixed network control and spool
information in the NJI header ... so JES2 releases operating at
different releases could result in JES2 at different releases, crashing
(also bringing down the operating system). It also would trash-can
network records where it didn't have the origin or the destination
network node defined in its local table (including where origin was
defined, but the records were just passing through to destination node
that was defined). misc. past posts mentioning hasp, jes2, nji,
networking
https://www.garlic.com/~lynn/submain.html#hasp
the internal network quickly exceeded 255 nodes ... so JES2 networking
couldn't be trusted as any intermediate node and was problematical even
as end-point. users on JES2 end-points were constantly arguing to have
their preferred (160-190) subset of internal nodes defined ... and in
constant battle with other users with different preferred (160-190)
subset. Changing JES2 node definitions typically came under control of
sites operating system change control ... which was a very laborious
process that frequently resulted in system change occurring at most once
a month.
https://www.garlic.com/~lynn/subnetwork.html#internalnet
the primary internal networking platform was vm370 which had cleanly separated the networking control information ... in fact a large library of VNET/RSCS "drivers" grew up, besides the native vnet driver, there were enormous numbers of (simulated) NJI drivers. It eventually became responsibility of the VNET/RSCS simulated NJI drivers to reformat NJI header information to confirm to the format expected by the JES2 at the other end of the connection. There was infamous case of JES2 systems in San Jose resulting in Hursley MVS system crashes ... and it was blamed on the local Hursley VNET/RSCS systems ... since the appropriate driver wasn't in place to prevent Hursley MVS systems from crashing.
JES2 NJI had also suffered from 23jun69 unbundling announcement
https://www.garlic.com/~lynn/submain.html#unbundle
In the mid-70s, pushing for release of NJI as part of JES2, it came under the heading of charged for software. The problem was that unbundling required that software fees/price at least cover internal costs. Typical approach was do low, medium, and high price scenarios (for the software) and then do forcast of number customers at each price ... and then verify that the number of forcasted customers times the price at least covered the internal costs. Company was still undergoing transition for such software priced methodology and they couldn't find any combination of JES2/NJI price and number of forcasted customers that covered the internal JES2/NJI costs.
On the other hand, the primary internal networking vm370 VNET/RSCS had close to zero internal costs (by corporate standards). However, anything "new" for vm370 was being blocked from being announced as products. The eventual (JES2/NJI) solution was to have a networking product defined as combined VNET/RSCS and JES2/NJI ... then VNET/RSCS and JES2/NJI paid the same price and the requirement was that the joint price times the joint market forcast had to cover the joint aggregate internal costs (VNET/RSCS and JES2/NJI) ... aka in effect, the VNET/RSCS revenue subsidized the JES2/NJI internal costs (JES2/NJI wasn't the only product that became subsidized by some related vm370 software product)

One of the things that could be done in MVT (and with some issues in SVS & MVS) was channel-end appendage that handled continuous, modifiable channel programs ... where the channel-end appendage got control and could modify (looping) channel program to do full-track operations w/o loosing rotation.
Long ago and far away, the univ. was converting from 709/1401 (student
jobs ran tape->tape on 709 IBSYS and then tapes moved between 1401 &
709 for unit record processing) to 360 ... initially the student jobs
ran something like 100 times longer elapsed time (fortgclg; enormous
amount of disk activity under os/360). HASP got it down to possibly
only 30 times longer. I started doing very custom stage2 sysgen ... i
took the stage2 card output from stage1 and reordered all the file &
PDS move/copies to optimize arm seek operation on newly built system
... achieving nearly three times increase in throughput for student
job fortgclg (still more than 10 times longer elapsed time than
709. It wasn't until installation of WATFOR that student job elapsed
time was less than 709 (on 360/67 running in 360/65 mode). Part of old
fall68 SHARE presentation ... cp67 had been installed jan68 which I
got to play with on weekends ... presentation includes significant
amount of cp67 rewrite that I had done spring/summer of 68, os/360
running under cp67 as well as work on base os/360 running native on
360/67 (in 360/65 mode)
https://www.garlic.com/~lynn/94.html#18
In the late 70s, they let me wander around the disk engineering,
development and product test labs (bldgs. 14&15 on san jose plant
site). They had tried using MVS as operating system for testing
development/engineering disk "testcells" ... but found it had 15min
MTBF (hang &/or crash, requiring re-ipl). As a result, they were doing
stand-alone prescheduled, around the clock testing. I offered to
rewrite input/output supervisor to make it completely bullet proof and
never fail ... allowing them to do on-demand, multiple testcell,
concurrent testing ... significantly improving development
productivity. misc. past posts getting to play disk engineer in
bldgs. 14&15
https://www.garlic.com/~lynn/subtopic.html#disk
In the mid-70, I started noting that disks were increasingly becoming
system throughput bottleneck. An example is this comparison that I did
in the 80s about disk relative system throughput had declined by an
order of magnitude since the 360/67 cp67 days and the 3081 vm370
days. part of old report in this old post
https://www.garlic.com/~lynn/93.html#31
apparently some disk division executives took offense and assigned the
division performance group to refute my claims. after several weeks,
they came back and effectively said that I had actually understated
the problem. One of the people then took the analysis and turned it

Simon Johnson on the Financial Crisis
http://www.econtalk.org/archives/2011/11/simon_johnson_o.html
Invoking the work of George Stigler, Johnson argues that the financial
sector has captured the regulatory process and the result is that
regulation and government intervention have been steered more by the
interests of the financial sector than to the benefit of the general
public. Johnson argues for capping the size of banks in order to
reduce the danger of systemic risk and the too-big-to-fail excuse for
bailing out banks. Johnson also discusses the role of the Fed in
subsidizing risk-taking and leverage in the financial sector.

with regard to upthread "deer in headlight" comments. Many of the 90s efforts (billions spent) was to redo overnight batch (bursting the limits of the overnight batch window) into straight through processing (done in parallel on large number of "killer micros"). the failure was the parallelization technologies being used introduced factor of 100 times more overhead (than cobol batch). also the programming was extremely human programming skill intensive ... still having to deal with large number of parallelization issues.
the effort I was involved in a few years ago ... attempting to get the
financial industry to revisit the issue ... was a front-end that
captured business rules ... which it translated into fine-grain SQL
operations. It relied on massive amount of work done in RDBMS products
for parallelization, robustness, high-availability, high-throughput,
business criticial, etc. The work on RDBMS ... especially business
critical, parallelization, and high-throughput ... also pretty much
masks characteristics of the underlying platform ... and has
contributed to making backend computing platforms commodities
... since the RDBMS subsume many of the operations previously
attributed to underlying operating system. ... as mentioned in above
SQL/DS post ... lots of past posts referencing original sql/relational
implementation
https://www.garlic.com/~lynn/submain.html#systemr
Even with several well-defined demos showing capture of business rules and turning into full-fledged production operation ... including extremely high parallelized (RDBMS) throughput for straight through processing ... the industry reaction was still "deer in headlights" ... and comments that the 90s effort had proved that it wasn't possible
The change-over to business rule driven also enormously reduces programming effort and life-time application costs.

In the today's paradoxical world of maximizing shareholder value,

the situation is the reverse. CEOs and their top managers have massive

reengineering, reimplementation, and recoding offered opportunity for moving to much less expensive platforms (killer micros) ... but required massive parallelization to get the necessary scale-up. they hadn't done speeds&feeds on the parallelization technologies being used which turned out to have 100 times the overhead of cobol batch ... totally swamping any anticipated scale-up and efficiencies.

Total aside, in late 90s, I was asked in to NSCC (this is before they merged with DTC to become DTCC) to improve the integrity of trading transactions (I had worked with some of the members earlier in standards bodies on various kinds of secure transactions). After working on it for some time, I was called in saying the work was suspended. It turned out that a side-effect of the trading transaction integrity work would have significantly improved transparency and visibility ... which is an anathema to wallstreet culture. This came up later in the congressional Madoff hearings and highlighted by the person that had tried unsuccessfully for a decade to get SEC to do something about Madoff.
Early in the century we were also somewhat involved in early drafts of Basel-2 which added a bunch of new quantitative measures as well as new qualitative section (sort of cross between sarbanes-oxley and ISO9000 ... where senior execs and board members had to know the financial institution's business processes). During the lengthy review process most of the changes in the original Basel-2 were eliminated ... primarily being opposed by US institutions ... where many in the rest of the world were in favor of the changes (and/or at least didn't oppose them). There were periodic references that US institutions were opposed to at least some of the Basel-2 draft changes because of the cost of dataprocessing changes. Some of this may have been risk adverse culture from the failures in the 90s ... and some may have been pure smokescreen.

Part of conflict and the "fog of war" can be obfuscation, misdirection, surprise, etc ... just specific kinds of large variety of possible "Acts" ... while maintaining superior "Observe" & "Orient".
One of the things that Boyd would stress in briefings (which has been hard to capture in OODA-loop) was constantly observing all possible facets; one might try and include it as part of having superior "Observe".
Superior "Orient" tends to imply better understanding. Understanding can result in narrowing options (discarding non-optimal possibilities) ... false understanding also tends to narrowing options (selecting wrong possibilities)
Corruption can be viewed as a kind of conflict and lack of transparency then is form of obfuscation and misdirection. In the late 90s, I was asked in to NSCC to look at improving the integrity of trading transactions. After working on it for some time, I was called in and told it was suspended; that side-effect of the integrity improvements would have significantly improved transparency and visibility ... which is an anathema to wallstreet culture. This was also highlighted in the congressional Madoff hearings by the person that had tried unsuccessfully for a decade to get SEC to do something about Madoff.
currently reading "Civilization: West and the Rest", characterizes Napoleon's grand strategy as unified Europe ... that Napoleon would show "profit" from campaigns ... more economic benefit to France than cost of the campaign. Losses at sea cut France off from the economic contributions of its colonies. This and operation of French gov. resulted in France borrowing at 6percent to finance its operation while enemies were able to borrow at less than 4percent to finance their operations.

It turns out that 3274 had very high channel busy overhead ... moving the 3274s off direct processor channels and replacing with another vendors channel extender controllers ... significantly reduced channel busy for doing the identical operations (and interference with disk operation) ... improving overall system throughput.

From: lynn@garlic.com (Lynn Wheeler) Date: 01 Dec, 2011 Subject: Deja Cloud? Blog: Old Geekre:
controller for 3330 was 3830 ... which was relatively fast electronics.
here is old reference/discussion to change from 3272 (controller for
3277 terminal) to 3274 (controller for 3278 terminal).
https://www.garlic.com/~lynn/2001m.html#19 3270 protocol
as per above, 3274/3278 had much worse interactive computing human factors than 3272/3277 (besides being significantly slower ... as per above). Eventually kingston came back saying that 3274/3278 wasn't targeted for interactive computing ... but was targeted for "data entry" (aka electronic keypunch). part of the problem/issue was that a lot of the electronics was moved out of the terminal head back into the controller ... which contributed to 3274/3278 have much poorer human factors than 3272/3277. That change also significantly increased the coax cable chatter protocol (between 3274 & 3278 compared to 3272 & 3277)... which also later results in ibm/pc upload/download performance for 3277 terminal emulation being several times faster than 3278 terminal emulation.
The processor in the 3274 was much slower in part because of all the additional work., ... which resulted in significant channel busy for not just for data transfer ... but also all the channel/controller control operations.
There was actually something similar in the transition from 3830 to 3880 disk controller.. The 3830 was for 3330 (and later 3350). 3880 was for 3380 and 3mbyte transfer (10 times that of 3330). The 3830 horizontal microcode ... the 3880 controller had special hardware for data transfer ... but it had a slow vertical microcode controller for all other operation ... which significantly drove up channel busy for control operations (much greater than 3830).
The disk engineering and product test labs (bldgs. 14&15 on main san jose plant site) had been doing dedicated, stand-alone, single device testing ... mainframes scheduled 7x24, around the clock. They had tried doing testing under MVS (potential of multiple concurrent testing) ... but MVS had 15min MTBF (hang &/or failure requiring re-ipl) with just single device testing. I offerded to completely rewrite input/output supervisor to make it bullet-proof, never crash ... so that they could do multiple, concurrent, on-demand testing ... significantly improving development productivity.
Eventually they started also using the test mainframes for online
general use (i.e. even several concurrent device testing only
represented a couple percent cpu use). Another result, was when things
weren't going the way they wanted, I would frequently get called to
diagnose what was going on. One monday morning, i got a call about
what did I do to their 3033 test system over the week-end ... because the
performance of the general online use and enormously deteriorated).
Eventually isolate that they had replaced the 3830 controller
(handling two 8-drive 3330 strings) with 3880 (handling same 16
3330s). The slow 3880 control functions were resulting in enormous
performance problems. Fortunately this was still six months before
first customer ship and were able to do some optimizing and masking to
mitigate some of the 3880 controller slowness. Misc. past getting to
play disk engineer in bldgs. 14&15
https://www.garlic.com/~lynn/subtopic.html#disk
However, the 3880 channel busy overhead was still significant. The 3090 had designed for 3830 controller overhead ... when they realized the magnitude of the 3880 ... they had to add significant more channels ... in order to achieve targeted system throughput. The additional channels required additional TCM ... and there were jokes that 3090 product was going to charge the 3880 for the extra TCM manufacturing cost (in each 3090). This started the myth that mainframes had so much more i/o capacity because of the enormous number of channels (where the truth was that the enormous number of channels were required to offset the inefficiency of the channel/controller operation)

slightly earlier 3270 protocol post
https://www.garlic.com/~lynn/2001m.html#17
that emulated 3277 with ANR (3277 coax protocol) had three times the upload/download throughput of emulated 3278 with DFT (3278 coax protocol). The difference was that a whole lot of electronics were moved out of the 3278 head and back into the 3274 controller ... cutting the cost of 3278 terminal manufacturing (compared to 3277 terminal) ... put a big processing load on the 3274 processor and enormously increasing coax protocol chatter between the 3724 and the 3278 (/3279, etc ... compared to 3272/3277). Also helped account for the significant channel busy overhead from 3274 for doing any operation.

Before 2000, we were called into one of the large airline "res" systems (ran on numerous TPF systems, use to be called ACP ... infrastructure included some number of MVS support systems) ... to look at what they called the "ten impossible" things they couldn't do. After looking at it for awhile ... went away and totally rewrote it from scratch in two months to run on large workstation.
In turns out that their existing design had come from the 60s where reservation needed to look up possible flights (to get from origin to destination) stored on disk ... basically large database problem. The issue by the mid-90s was that it was possible (with a little compression) to represent all scheduled airports in the world and all commerical scheduled flights in the world as memory resident information. I had recently been involved in large application that did optimal physical chip & board layout ... and used some of the technology to search for all possible flights between origin and destination. On high-end workstation of the time, it would run 100 times faster than the TPF database lookup. I then was able to implement all "ten impossible" things ... and with all the additional function, it still ran ten times faster than the database lookup (part of the ten impossible things was to be easily sized to handle total worldwide workload lookup).
Then the hand-wringing started. A big part of the reason for the ten impossible things was that they had several hundred people involved in the care and feeding of the database implementation. Paradigm shift to memory resident of all possible flights and airports (aka automated procedure from OAG master sequential file to memory resident) eliminated all that manual care&feeding of massive DBMS and made the ten impossible things straight-forward. It eventually came down to they wanted me to go away and pretend the whole thing never happened (the executive in charge would have lost a very large empire).
It turns out that within the past couple years, the whole application and associated data easily fits on a smartphone. Furthermore, some of the smartphone processors rated at 1000mips, theoretically can handle their projected workload lookup for the whole world.

from above:
Breaking that down: JPM Chase holds 11% of the world's derivative
exposure, Citibank, Bank of America, and Goldman comprise about 7%
each. But, Goldman has something the others don't -- a lot fewer
assets beneath its derivatives stockpile. It has 537 times as many
(from 440 times last year) derivatives as assets. Think of a 537 story
skyscraper on a one story see-saw. Goldman has $88 billon in assets,
and $48 trillion in notional derivatives exposure. This is by FAR the
highest ratio of derivatives to assets of any so-called bank backed by
a government

Also referenced in the post was the FED giving GS a bank charter so it would be eligible for various FED assistance. Now the rhetoric on the floor of congress was that the primary purpose of GLBA was if you were already a bank, you got to remain a bank ... but if you weren't already a bank you didn't get to become a bank (specifically calling out Walmart and M'soft) ... this is besides the other things in GLBA like repeal of Glass-Steagall and opt-out privacy provision federal pre-emption of the in-progress Cal "opt-in" legislation (that only allowed personal information sharing when individual specifically was on record authorizing it). Roll forward to the bubble collapse and FED is handing out bank charters to its apparent friends (theoretically violating GLBA?).

re: CEOs won't act to protect (secure) their own companies if it cuts

https://www.infosecisland.com/blogview/18447-Security-2012-Blood-in-the-Water.html
I observed that actually, top executives refuse to protect their own
company if it cuts into their compensation ... referencing that
apparently GAO didn't think SEC was doing anything last decade and
started doing reports showing uptick in fraudulent public company
financial filings ... even after Sarbanes-Oxley ... which was supposed
to eliminate such activities (prompted by Enron & Worldcom):
https://www.gao.gov/products/gao-06-1079sp
also in this reference about Sarbanes-Oxley
https://plus.google.com/u/0/111646203865345303496/posts/2yc39t6A2Cq
I mentioned that at the time of passage of Sarbanes-Oxley there were snide references that it was just full employment for the audit industry (low expectation that anything would actually change). also has some recent references to major fraud ... where large audit institutions were involved and nothing was being discovered (recent reference seen on the internet: Enron was a dry run and it worked so well it has become institutionalized)
The responsibility/accountability ... showed up in the congressional Madoff hearings in slightly different way. The person that had been trying unsuccessfully for a decade to get SEC to do something about Madoff was asked if new regulations were required. His response was that while new regulation may be required, much more important was transparency and visibility. All the regulations and (additional sarbanes-oxley) auditing actually requires a regulatory agency that is going to hold companies accountable (which appears to have been nearly totally missing during the last decade).
In the late 90s, I had been called in to the NSCC (before it merged with DTC for DTCC) to look at improving the integrity of trading transactions. I worked on it for awhile, but then was called to say that the work was suspended. The issue was that a side-effort of the trading integrity work would have significantly improved the transparency and visibility ... which appears to be an anathema to wallstreet culture (very dark/closed environment).

In the congressional hearings into the rating agencies ... they played the pivotal role in the financial bubble by selling triple-A ratings on toxic CDOs (when they knew that the toxic CDOs weren't worth triple-A rating). The testimony also pointed out that the rating agency business process became misaligned in the early 70s when they switched from the buyers paying for the ratings to the sellers paying for the ratings (opening them up to conflict of interest, aka while the ratings were for the benefit of the buyers, the rating agencies interest became aligned with the sellers that were paying for the ratings). The other observation was that regulation is much easier when business processes are aligned (people motivated to do the right thing, which goes along with transparency and visibility), but becomes extremely difficult when the business processes are misaligned (people motivated to do the wrong thing)

and "Civilization: The West and the Rest" is number three on that list.
My wife's father was awarded a set of books at West Point which are Fiske history lectures from the 1880s.
Fiske and Ferguson both seem to present a very similar message about evolution of democracy and capitalism requiring sense of morality (necessary for success of capitalism which requires quite a bit of trust) and work ethic, which were tied to religious upbringing. They both differentiate Catholic and Protestant Europe ... on the education and literacy issue ... with Protestant cities in Europe fairly quickly reaching four times the average GDP/person of Catholic cities. Also Protestant missionaries had much stronger emphasis on education and literacy.
Both Fiske and Ferguson refer to wealthy individuals and companies corrupting congress with money resulting in extreme downside for the country.
Ferguson has related scenario about the recent explosion of Protestant religion in China. That missionaries up through most of past century saw very little uptake in China. However, he points out that in modern China there is large amount of graft, corruption and lack of morals and quotes (Chinese) Protestant capitalist that the only people that can be trusted are other Protestants.

In the mid-70s, I started noting that disks were increasingly becoming
system throughput bottleneck. An example is this comparison that I did

days. part of old report in this old post

they came back and effectively said that I had actually understated
the problem. One of the people then took the analysis and turned it

One of the points that I had made was if I went from 360/67 cp67 number of CMS users to 3081 vm370 based on cpu mip rate and memory size, a normal 3081 would have been running 4000 CMS users ... however 3081 vm370 was typically running more like 300 CMS users ... which was approx. change in disk technology throughput (rather than cpu mip rate and memory size change, aka approx. what i was saying that relative system disk performance had declined by order of magnitude)

I've claimed that John Cocke's creation of 801/risc in the 70s was to go to the opposite extreme as the FS effort. Also original 801/risc wasn't going to provide for any (multiprocessor) cache consistency ... which I've claimed is in re-action to the extreme hardware penalty that 370 has paid for its level of memory consistency (and multiprocessor cache consistency)
In the 1980 timeframe there was massive program to replace large number of internal microprocessors with 801/risc (Iliad chips); follow-on to s/38 (as/400) was going to be Iliad, follow-ons to 4331&4341 (4361&4381) were going to be Iliad (i.e. low-end & mid-range 360s/370s had been implemented with 360/370 instruction set simulated in "microcode" ... somewhat analogous modern day Hercules) as well as large number of other microprocessors used in controllers and devices. For various reasons all the Iliad efforts floundered and reverted to traditional one-off, custom CISC chips.
risc/801 ROMP (joint research/office products) was going to be
follow-on for Displaywriter. When that project was canceled, they
looked around and decided to retarget for the unix workstation
market. They hired the company that had done the AT&T Unix port to PC
(PC/IX) to do one for ROMP ... which was released as AIXv2 for the
PC/RT. RIOS was the follow-on chipset to ROMP for the unix workstation
market and was released as RS/6000. Somerset then was joint IBM,
Motorola, Apple effort to do a single chip 801 as well as address the
cache consistency issues resulting in parallel family of 801
chips. Rochester also participated and eventually AS/400 was finally
migrated from custom CISC chip to 801/risc. Later the POWER (rios
chipsets) and POWER/PC were merged into single chip line. Apple
supposedly eventually moved off POWER to x86 because the lack of
effort being put into low-power, power chips for mobile

there was native tcp/ip product on vm370 (later released on mvs by simulating some vm370 operations in mvs). it used approx. full 3090 processor getting 44kbytes/sec thruput.
i did enhancements for rfc1044 support and in some tuning tests at
cray research on 4341 got full channel speed thruput using only modest
amount of 4341 processor (about 25times increase in thruput and
possibly 500 times improvement in bytes moved per instruction
executed). misc. past posts mentioning rfc1044 support
https://www.garlic.com/~lynn/subnetwork.html#1044
part of the issue was that communication group tried hard to prevent
release of tcp/ip support (they were strongly trying to preserve the
3270 terminal emulation paradigm and prevent anything that might smack
of peer-to-peer networking and/or client/server). they couldn't quite
stop release of tcp/ip support but then they claimed since they owned
everything that crossed the datacenter wall, the controller used by
tcp/ip was their responsibility. What it turned out to be was a bridge
that sat on the channel interface rather than a tcp/ip router ... so
all the router function and mapping between ip and LAN MAC level had
to be done in mainframe software. For rfc1044, I got a channel
interface box that had full tcp/ip router function and could use
different subchannels to simulate full-duplex operation ... different
dedicated subchannel addresses for input and output. misc. past posts

in the late 80s, a senior disk engineering got a talk scheduled at the annual communication group world-wide, internal conference ... and opened the talk with the statement the communication group was going to be responsible for the demise of the disk division. the disk division was seeing large amount of data (and related applications) fleeing the datacenter to more distributed computing friendly platforms. the disk division had tried coming up with a number of products to address the situation, but was constantly being vetoed by the communication group (part of protecting its terminal emulation paradigm install base). the disk division was starting to see close to double digit annual decline in sales because of the data & applications fleeing the datacenter. since then the prediction of the demise of the disk division has come to pass.

The communication group was attempting to preserve their terminal emulation install base and block all efforts that might have peer-to-peer networking, client/server, distributed computing ... efforts also included spreading lots of misinformation.
Part of this was late 80s converting the internal network to SNA
... although it was trivially obvious that it would be significantly
better to have converted the internal network to TCP/IP. The internal
network had been larger than arpanet/internet from just about the
beginning until possibly late 85 or early 86. One of the reasons for
internet exceeding internal network in size was that workstations and
PCs were starting to appear as network nodes ... while the internal
network was restricted to machines as terminal emulation. misc. past
posts mentioning internal network

as mentioned upthread, we had been working with several
organizations leading up to what was to become the NSFNET backbone
(operational basis for the modern internet). However, when NSFNET
backbone RFP was finally released, internal politics prevented us from
bidding. The director of NSF wrote the corporation (copying CEO) a
letter trying to help, but that just made the internal politics
worse. misc. past posts mentioning NSFNET backbone
https://www.garlic.com/~lynn/subnetwork.html#nsfnet
the communication group was also spreading lots of misinformation
internally about how SNA could even be used for the NSFNET
backbone. Eventually somebody collected a lot of the misinformation

CKD, controller and channel design is left over from large number of technology trade-offs from the original 360 in the 60s. Lots of complexity and idiosyncrasies are exposed for the user to deal with. By the mid-70s, most of those trade-offs had inverted and the designs were obsolete.
Part of the issue was scarce, expensive electronic memory ... so there was lots of leveraging processor main storage for all sorts of other purposes. Part of this was channel had end-to-end hand shake for every byte transferred. This was slightly relaxed with datastreaming for 3mbyte channels in the 80s ... allowing a few bytes to be transferred per end-to-end hankshake.
In the 80s, we were working with several labs on standardization various stuff and going to related standards meetings ... LANL was pushing the standardization of the Cray 100mbyte channel as HiPPI. LLNL had high performance serial copper that was pushing for as standard and move to fiber (with full-duplex protocols removing end-to-end serialization allowing continuous outbound transmission overlapped with continuous inbound transmission) ... as FCS/fiber-channel standard. SLAC was pushing for similar approach with fiber ... but defining protocols for things in addition to I/O ... including high-performance multiprocessor memory bus operation .. as SCI/Scalable Coherent Interface.
The 3090 was trying to break into the numerical intensive market ... with vector processor facility option. However, the market tended to also use HiPPI so 3090 folks tried to come up with some way for 3090 to do HiPPI I/O. The problem was that there was no way that 3090 I/O could come close to handling 100mbyte/sec operation. Eventually the found a way to hack into the side of the 3090 expanded store memory bus with some extremely unnatural acts to hook up HiPPI interface using simulated expanded store memory operation for HiPPI i/o transfers.
There had been fiber channel technology kicking around POK for a decade that never quite got out. That technology was taken, hacked so it ran 10 percent faster, could do concurrent transfers in both directions simulations, and used much less expensive and reliable components. About the same time ESCON was eventually released, 220mbit/sec "SLA" was released for the RS/6000. The issue was ESCON could do approx. 17mbyte/sec burst transfers but could never approach 17mbyte/sec sustained transfers. SLA with optimized operations could approach over 400mbits/sec sustained (i.e. over 200mbites/sec concurrently in each direction).
About the same time, Hursley was doing Harrier ... which was
80mbit/sec serial copper (slower but somewhat similar to the LLNL
precuser to fiber channel standard). They encapsulated SCSI protocols
in packets and supported simultaneous concurrent transfer in each
direction (approaching 160mbits/sec sustained transfer). This was
eventually upgraded to 160mbit/sec links (concurrent each direction)
and offered as "SSA". old post referencing Jan92 in Ellison's
conference room ... mentioning cluster scale-up, fiber channel standard
operation, as well attempting to push Harrier as interoperable
operation with FCS (but at slower speed, and with option to do serial
copper rather than serial fiber ... as opposed to going to market as a
totally non-interoperable implementation).
https://www.garlic.com/~lynn/95.html#13
This fibre channel standard (started '88 with ansi standard '94) wiki
https://en.wikipedia.org/wiki/Fibre_Channel
mentions market chose FCS over SSA ... but what I had wanted was SSA interoperable with FCS. FICON eventually ships for the mainframe, but long after it was in general use as fully asynchronous, simultaneous transfers by lots of other platforms (on 1gbit FCS connections being able to approach 2gbit/sec operation, simultaneous, asynchronous transfers in each direction).

The RS/6000 engineer that worked on 220mbit SLA, then wanted to do a 800-mbit version. We were able to convince him to participate in the FCS standards meetings instead (on 1gbit/sec concurrent in each direction). Unfortunately, some corporate channel engineers started participating in FCS meetings also ... pushing layering some extremely unnatural acts on top of FCS ... basically overlaying ESCON overtop of FCS as FICON.

later the communication group hires a subcontractor to do a tcp/ip stack implementation in VTAM. the initial implementation had tcp performing significantly better than lu6.2.

PRODUCT POSITIONING
There is a rapid increase in the number of workstations used
for engineering/scientific computing as well as increased use by many
other industries. The Network File System is popular as a file
server to support these workstations. The Network File System on
IBM TCP/IP for VM allows the IBM systems running VM to act as a file
server for the engineering/scientific workstations. The DASD and
associated VM programming support provide a high quality system for
use as a file server in this environment. Systems of other vendors
with the NFS 3.2 client protocols implemented may access files on the
VM system using TCP/IP and the NFS feature. The IBM AIX Network File
Systems provide client function that will access these files. The
IBM Personal Computer feature of TCP/IP for VM does not contain NFS
client function and cannot access NFS files on the VM system.
MARKETING STRATEGY
IBM TCP/IP for VM and the Network File System should be
marketed to customers with VM systems and engineering/scientific
workstations with NFS 3.2 installed.

DESCRIPTION
NETWORK FILE SYSTEM FEATURE
The Network File System (NFS) feature provides file server support
for the NFS 3.2 protocols developed by Sun Microsystems, Inc. This
support enables the VM system to act as a file server for vendor
systems with the NFS 3.2 client function installed. NFS has been
implemented on the IBM AIX systems as well as many other vendor's
systems. Optional encryption of file handles requires
IBM Information Protection System Cryptographic programs for VM/CMS
(5796-PPK) or a customer-supplied encryption procedure. The NFS
feature does not include the Network File System client function.
The Network File System feature uses the *BLOCKIO CP system
service, and can reference CMS-format minidisks on any DASD supported
by *BLOCKIO. Special formatting of the CMS minidisk by the RESERVE
command is not required.
The Network File System feature includes Remote Procedure
Call. The RPC function of the Network File (RPC) System makes remote
procedures appear as if they were local. Both the NFS and RPC
protocols adhere to the External Data Representation (XDR)
specification, which allows the protocols to be independent of
machine internal format.
The RPC is implemented as a library of procedures. The
customer who wishes to write applications using RPC will require
IBM C for System/370 (5713-AAH) and the IBM VS Pascal Library
(5668-717).
OTHER TCP / IP FOR VM FUNCTIONAL ENHANCEMENTS IN VERSION 1.2
9370 X.25 Communications Subsystem Support
A driver is provided to support connection of the IBM TCP/IP for VM
program offering to an X.25 network using the 9370 X.25
Communications Subsystem.
REMOTE EXECUTION DAEMON
A remote execution daemon (server) (REXECD) is provided to allow
remote execution of VM EXECs and CP/CMS commands. Systems with the
Remote Execution (REXEC) client function installed may initiate
execution of VM EXECs and CP/CMS commands from the remote system.
IBM AIX/RT (TM) and IBM TCP for the Personal System/2 (R) (PS/2 (R))
have the client REXEC function available.
(TM) Trademark of the International Business Machines Corporation.
(R) Registered trademarks of the International Business Machines
Corporation.
SNA NETWORK LINK
IBM TCP/IP for VM installed on a VM system with IBM ACF/VTAM for
VM/SP (5664-280) may interconnect the TCP/IP network via SNA to
another TCP/IP network attached to a remote VM system with IBM TCP/IP
for VM and IBM ACF/VTAM for VM/SP installed on the remote system.
The SNA LU-0 protocol is used to link the two systems.
CMS X WINDOW SYSTEM (VERSION X.11)
The CMS X Window System is an application program interface (API)
which allows a CMS program access to a bit-mapped, high-resolution
display connected to system running an X Window System (Version X.11)
server program. The IBM AIX/RT X Window System Version 2.1 offers
the required X Window System server function. The X Window System
API allows the development of code portable across operating systems
and displays. The CMS application using the X Window System client
function communicates with the X Window System server function on the
AIX system. The CMS applications using the X Window System function
will be written in C and require the IBM C for System/370 program
offering (5713-AAH) and the IBM VS Pascal Library (5668-717). TCP/IP
is used as the communication protocol between the VM system and the X
Window System server system.
HYPERCHANNEL SUPPORT (DRIVER)
A driver is provided to support connection of the IBM TCP/IP for VM
program to a NSC HYPERchannel network using a NSC IBM channel
adapter. Support conforms to specifications outlined in RFC1044 for
16-bit address configuration.
NOTE: Customer application programs that interface to IBM TCP/IP for
VM and written in IBM C for System/370 Program Offering (5713-AAH)
require the IBM VS Pascal Library (5668-717) for execution.
For additional information on TCP/IP for VM, refer to
Programming Announcement 287-165, dated April 21, 1987.

The low hanging fruit was part of the massive migration off mainframes in the late 80s and 90s. As the low-hanging fruit fled ... what was left was the increasingly convoluted stuff ... some cases where original source no longer even existed and the original implementers were long gone. It was one of the things that made Y2K remediation such a monumental, sometimes horrifying prospect (although some of the Y2K remediation was accomplished by migration). At some point the remaining stuff were the things that had proved extremely difficult and apparent risk of migration appeared to exceed the possible benefits.
lost/opaque legacy executables also helps account for continued existence of (simulated) CKD DASD ... even though there haven't been such disks manufactured for decades ... which also accounts for a huge amount of overall continuing mainframe use.
all the disks manufactured for decades have been fixed-block (obsolete
CKD DASD is purely a simulated artifact). This old past about early
jan92 meeting in ellison's conference room included fiber-channel to
fixed-block disks ... long before FICON over fiber-channel ever became

recent post how disk division claimed that the communication group would

waging wars against client/server, peer-to-peer networking, distributed computing ... including spreading all sorts of mis-information and other kinds of FUD.
the disk division was starting to see nearly double digit annual drop in sales ... data&applications fleeing the datacenter to more distributed computing friendly platforms ... they had come up with a number of products to address the problem ... which were constantly being vetoed by the communication group.
my wife had run into problem earlier when she had been con'ed into going
to POK (land of large mainframes) to be responsible for loosely-coupled
architecture (mainframe for cluster). She had developed peer-coupled
shared data architecture ... but there would be periodic wars with the
communication group over having to use SNA for loosely-coupled
operation. There would be a temporary truce ... that she could use
anything she wanted within the datacenter (but communication group had
strategic ownership of everything that crossed the datacenter walls)
... but then the battles would startup again. The battles contributed
to her not remaining long in the position. misc. past posts
https://www.garlic.com/~lynn/submain.html#shareddata
Another scenario was the workstation division had done their own AT-bus (16bit) 4mbit token-ring adapter card for the PC/RT. Then for the RS/6000 (with microchannel), the workstation division was forced to use standard PS2 microchannel cards (joke that except for processor, RS/6000 was going to be as slow as PS2). The microchannel 16mbit token-ring card had design point of very low throughput per card ... aka 300 or more PCs on shared 16mbit LAN ... limited to terminal emulation. As a result, PC/RT server with 4mbit token-ring card had higher througput than RS/6000 server with microchannel 16mbit token-ring card.
In that time-frame, we had come up with 3-tier architecture ... and was
out pitching to corporate customer executives ... as a result we were
taking loads of barbs from the communication group
https://www.garlic.com/~lynn/subnetwork.html#3tier
another example in the time-frame, the communication group was
forcing the conversion of the internal network (had been larger
than arpanet/internet from just about the beginning until sometime
late '85 or early '86) to SNA. Recent post about misinformation

network conversion to SNA

in the mid-80s, top corporate was predicting revenue (nearly all mainframe) would shortly double from $60B to $120B and set out on a massive internal building program to double mainframe hardare manufacturing capacity (example was bldg. 50 on disk division san jose plant site). However at the time, it was relatively easy to show that part of the business was starting to head in the opposite direction (which possibly wasn't a career enhancing move).
Then in the early 90s, it came to pass as the company went into the RED. the company recovered ... but mostly from restructuring and moving into new revenues in areas other than mainframe hardware Then later, the prediction about disk division demise also came to pass.
other trivia regarding the ibm-main/alt.folkore.computers

some of the existing routines are still vs/pascal. 5798-DRG was the
wiscnet support from Wisconsin
https://www.garlic.com/~lynn/2011p.html#45
... which a couple years later was replaced by ibm 5798-FAL, ibm
implementation in vs/pascal. It was later ported from vm370 to MVS by
simulating some of the vm370 functions in MVS. Much later the
communication group hired a consultant to do tcp/ip stack
implementation in VTAM (initial implementation ran much faster than
LU6.2 ... but he was then told that everybody knows a "correct" tcp/ip
runs slower than LU6.2 and they were only going to pay for a "correct"
implementation). However, some parts of the implementation apparently
continued to carry forward 5798-FAL components implemented in
vs/pascal. 5798-fal announce referenced here

From: lynn@garlic.com (Lynn Wheeler) Date: 07 Dec, 2011 Subject: Has anyone successfully migrated off mainframes? Blog: Mainframe Expertsre:
There was article (I think washington post) in the early 80s calling for 100% unearned profit tax on the US auto industry. The scenario was the justification for foreign auto import quotas was to reduce competition and give the US industry profits that they would then use to completely remake themselves. Instead they just skimmed the profits and continued business as usual.
About that time, I started sponsoring Col. Boyd's briefings at IBM
about being adaptable and agile. misc. past posts mentioning Boyd
https://www.garlic.com/~lynn/subboyd.html#boyd1
misc. URLs from around the web mentioning Boyd and/or OODA-loops
https://www.garlic.com/~lynn/subboyd.html#boyd2
Roll forward to 1990, the US auto industry has C4 task force looking to completely remake themselves, they invite technology vendors to participate since they plan on heavy leveraging technology as part of the complete make-over. During the meetings they could accurately articulate the competition from foreign makers and what the US industry needed to do. One of the things was the US industry was on a 7-8 year elapsed time product cycle (from start to rolling off the line, minor cosmetic changes annually with possibly two efforts going on overlapped, offset by 3-4yrs) ... while the foreign imports had cut the elapsed time in half and were in the process of cutting it in half again (able to more quickly adapt to changing market and/or technology). Offline, I would needle the participants from POK about how could they possible help since they were on similar elapsed time product cycle as US auto industry.
During the 1970s FS period, lots of 370 efforts were killed off
(planning on FS completely replacing all 370). misc. past FS posts
https://www.garlic.com/~lynn/submain.html#futuresys
With the death of FS, there was mad rush to get products back into 370
product pipelines. In effect both 303x and 3081 being overlapped. 303x
was the quick&dirty, 3031&3032 were effectively new covers for 158&168
and 3033 was 168 logic design remapped to 20% faster chips ... some
late work finally managing to get 3033 up to 1.5times that of
168. Some of this is discussed in more detail here
http://www.jfsowa.com/computer/memo125.htm
As soon as the 3033 is out the door, the 3033 engineers start on trout (aka 3090), overlapped with ongoing 3081 effort (lots of analogies with US auto industry).
Along with the big drop off in mainframe during the late 80s and early 90s, and the company going into the red, not only is it noticed with comments in the press ... but also internally. Hudson valley starts to look a little like scorched earth, mainframe operations are being shutdown and lots of people laid off. There was joke circulating around POK about the last person to leave needs to turn off the lights (similar to a 60s billboard seen in Seattle after massive Boeing layoffs)
Roll forward to the last couple years, the mainframe group managed to survive and has become slimmer as well as much more agile and adaptable (wish I could say the same for the US auto industry). Part of becoming slimmer is starting to heavily leverage industry standards ... rather than constantly everything having to be proprietary.
disclaimer ... in the 70s, I was part of small group that would visit POK and we got the 3033 processor engineers interested in working on a 370 16-way SMP (multiprocessor) implementation in their spare time. At first top management thought it was a good thing ... then somebody informed the head of POK that it could be decades before the POK favorite son operating system had 16-way support. Then some number of people were invited to never visit POK again ... and the 3033 processor engineers were told to get their noses back to the grindstone and not do anything else.

DOS, VS, and VM was low&mid-range 370 market (VM actually spanned the
high-end market as well). in the late 70s, 4331&4341 were introduced
for that market ... misc. old 43xx email
https://www.garlic.com/~lynn/lhwemail.html#43xx
these machines were referred to "E" ... it was somewhat the "new architecture" for low&mid-range equivalent to 370-xa at the high-end. Basically a lot of virtual memory gorp was moved down into the hardware ... for a single virtual address space (a little like facilities that were introduced in vm370 for vs1 handshaking running in a virtual machine). This gave rise to the reference to DOSE and VSE (ran straight 370 mode for vm370)
Similar to upthread reference to disk engineering & product test
getting one of the first engineering 3033 ... there was something
similar for 4341. As a result, I had better access to 4341
benchmarking than the endicott 4341 performance test group ... and so
I ran some benchmarks for them ... as mentioned in some of the
emails. One of the benchmarks was from national lab ... show 4341
outperforming 158&3031 ... when national lab was looking at an order of 70
machines (somebody leaked the numbers to the press, but it wasn't
me). Past discussion of 4341 benchmarks including clusters of 4341
providing better thruput, price/performance than 3033 (as well as much
lower floor space and environmental requirements):

explosion in sales. Something similar happened to DEC with their VAX
machines for the same low&mid-range markets. This old post gives a
decade of VAX sales, sliced&diced by year, model, US/non-US
(skewed somewhat by inclusion of the microvax ... MVI & MVII
numbers)
https://www.garlic.com/~lynn/2002f.html#0
Small unit sales of 43xx machines saw similar volumes as VAX. The big difference for 43xx machines was large corporate orders for hundreds of machines at a time ... which became the leading edge of the distributed computing wave (before PCs). 4361&4381 were the follow-on models to 4331&4341 and were expected to continue the volume explosion ... which didn't happen. As can be seen in the VAX numbers, by that time, the low&mid-range market was already starting to migrate to workstations & large PCs.
The big explosion in 43xx machines could also be seen internally,
being placed out in dept. supply & conference rooms (contributing to
scarcity of conference rooms in the corporation). vm/4341 machines
also were huge increase in the size of the internal network ... old
post that includes all internal network world-wide locations that had
one or more nodes added during 1983:
https://www.garlic.com/~lynn/2006k.html#8
The internal network was larger than the arpanet/internet from just
about the beginning until possibly late '85 or early '86. 1Jan1983 was
when the arpanet/internet had big switch-over from IMP-based network
(with possibly 100 IMP network nodes and approx. 250 connected hosts)
to TCP/IP protocol. This was about the time that the internal network
was approaching 1000 nodes. old reference:

Boyd would advocate viewing from every possible facet ... and discussions with him were rarely straight-line focused ... constantly bringing in large number of different things. The corollary in business is trying to simplify measure to single variable and then optimize that single measure ... where attempting to discuss multiple variable optimization is met with blank stares or even hostility.
A related ... but different thing happened during the development of
original SQL/relational RDBMS implementation ... where relations were
simplified to association with single variable (key). This table
paradigm made it much more efficient for big early adopter
... financial transactions ... but enormously increased the difficulty
for handling "real-world" information ... which rarely fits into table
paradigm. misc. past posts mentioning development of original
SQL/relational RDBMS implementation
https://www.garlic.com/~lynn/submain.html#systemr
I had example of focused/complex about a decade ago ... large financial processor had application ran all night on 40+ maximum configured mainframes (>$1B+ cost) ... the application originated in the 70s and significantly grown over the decades ... and the dataprocessing hardware was primarily sized for doing this overnight application.
There was large staff dedicated to managing the performance of the application ... but even with a couple hundred people, it had become increasingly "bloated" over the years. The primary performance technology was "hot-spot" monitor (how much time did the application spend in each small segment of code) ... which would be used as input to software organization as to where they should concentrate on improvements. This approach had been constantly milked for very long time and so there was fewer and fewer productive areas of improvements shown. They had also recently hired a dataprocessing performance consultant that used an analytical model to profile system operation looking for potential bottlenecks.
Now in the 70s at the science center, some past posts
https://www.garlic.com/~lynn/subtopic.html#545tech
we had spent large amount of time on different performance technologies ... including hotspot monitors, system simulation analysis, system analytical models and multiple regression analysis (looking at aggregate large-scale operation). Some of this work also eventually evolves into things like "capacity planning" with lots of work on workload profiling and system profiling.
It turns out that the newly hired consultant had acquired the rights to multiple decade descendent of one of the science center's analytical models (implemented in APL language) and had run it through an APL-language to C-language conversion and was using it at major dataprocessing installations around the world. Renewed emphases on hot-spot analysis and system analytical modeling yielded a few percent improvement.
I offered to use multiple regression analysis with very high-level activity functional counters ... which found a relative complex, infrequent activity that accounted for 21% of total overall application processing. Part of the issue was that the infrequent activity didn't involve a lot of unique code but repeatedly invoked a large amount of other code (that had been individually extensively optimized). With the multiple regression analysis available they re-examined this particular area and realized it was being repeated three times for every occurrence when it needed only to be run once. This reduced the aggregate overhead from 21% to 7% ... a 14% savings of >$1B+ dataprocessing (nearly $200m).
My assertion was this was extremely Boyd .... aka both 1) viewing the activity from lots of different facets (hot-spot, analytical model, multiple regression) as well as 2) complimenting very low level analysis (hot-spot) with very high level analysis (multiple regression) ... sometimes the forest can be lost in the trees.

One of the reasons that PCs became popular was that you could get PC for about the same price as 3270 ... and in single desktop footprint, get 3270 terminal emulation as well as some amount of local computing (which started out fairly simple ... but became more and more powerful as the PC technologies evolved).
One of the simplest terminal emulation was correct some of the human factors issues with 3278 terminal. In the 3277, with some local hacking ... it was possible to adjust the repeat key delay and repeat key rate ... for instance cursor movement. Another annoying 3270 characteristic (for interactive computing) was if you were typing at the time the screen updated ... the keyboard would lock and person would have to stop and hit reset. Again it was possible to do a hack to 3277 to eliminate the keyboard locking when screen update.
For 3274/3278 ... lots of the electronics were moved out of the head
back into the 3274 to reduce the cost of 3278 manufacturing (compared
to 3277) ... eliminating human factors hacks that had been done to
3277. Complaints to kingston eventually came back with the response
that 3278 wasn't designed for interactive computing ... but for data
entry (aka next generation keypunch). Old post with some 3274/3278
comparisons with 3272/3277 from early 80s
https://www.garlic.com/~lynn/2001m.html#19
I was responsible for large-scale vm370/cms service .... operated at
100% cpu busy ... but giving .11sec interactive trivial cms (system,
90% percentile) response ... coupled with 3272/3277 hardware of .086
seconds ... resulted in .196 response seen at the terminal. This was
in the days with human factors studies showing increase productivity
for sub-second (actually quarter second) response. As referenced in
the above post ... it was very unusual to have TSO system with
response as good as 1second ... and frequently multi-second response
(part of the justification for the human factors studies ... since
MVS/TSO was claiming subsecond response was important ... because they
weren't able to achieve subsecond responses). more recent post (here
in ibm historic computing) about reference to subsecond response study
https://www.garlic.com/~lynn/2011d.html#53
The 3270 terminal emulation contributed to early uptake in ibm/pc
... no-brainer business justification to switch from justified 3270
terminals to ibm/pc with additional function at no additional
cost. Later (as noted in original refrenced posts), communication
group attempting to protect its terminal emulation install base (and
fend off client/server, distributed computing, peer-to-peer
networking) accelerated applications leaving mainframe. some past

mentioned in 4300 email collection

at least the san jose plant site, they were also looking at trying to handle big increase in processing demand and the existing datacenter machine rooms were bursting at the seams with high-end mainframes. Putting 4341s out into every departmental areas was a way of alleviating huge increase in processing demand. One of the issues was a lot of the high-end processing were applications making use of lots of sophisticated MVS system services. Part of the issue of moving those applications out to the distributed vm/4341s was adding the additional MVS services simulation to CMS (which worked out to approx. 12kbytes of new assembler code).

One of the things going into the big corporate downturn in the late 80s ... was apparent blinders in much of the corporation as to what was happening. I had sponsored Boyd's briefings in IBM starting back 1983 about business agile and adaptable to changing situations. In the early 90s, I remember wandering around Somers and talking to lots of different executives about the need to adapt to changing business climate and nearly all of them could characterize what was happening ... but none of them appeared to be able to actually make any change (I would characterize it as most of them were hoping that they could make it to retirement before major changes started to wash over the corporation). In Boyd discussions there was items about the generals having some of the worst disasters in war were ones that had previously had the major successes ... the major successes setting them up to believing that they would never have to change even when circumstances radically changed.
In Oct, I was at a Boyd conference at Quantico and former commandant
of the Marine Corps wandered in to talk to us; he had leveraged Boyd in
the 1990 time-frame to do makeover of the Marine corp.

Note that migration off datacenter mainframes starting in the late 70s to distributed vm/4341s (but still 370) was frequently because lack of responsiveness of datacenters to the users needs ... things appeared to be cast in concrete and evolving at glacier speeds (although that may become an inappropriate metaphor, recent reports saying glacier change may go non-linear this century). This continued in the late 80s and early 90s ... but to other kinds of distributed computing platforms. There have been some number of grandiose migration failures ... frequently involving legacy applications where there is little preserved institutional knowledge of how & why the existing applications work.

Complexity is also frequently taken as a snakeoil in security (complexity as form of obfuscation as to what is really going on) ... along with exploits tending to being proportional to complexity (and contend that the snakeoil analogy isn't just limited to security business).
In the US there has long been periodic rant about military-industrial-complex ... recent item was that Eisenhower originally was going to say military-industrial-congresional-complex (MICC), but shortened it at the last minute. There has been frequent items that DOD has been leqally required for decades to pass financial audit ... but has yet to have one (claims that it amounts to unaccounted trillion during the last decade)
I've used an analogy for FRCC ... or financial-regulatory-congressional-complex.
I remember original draft of Basel-2 having both additional quantitative measures as well as a new qualitative section ... which basically required top executives and board being able to demonstrate end-to-end understanding of the business processes ... sort of combination of ISO9000 and Sarbanes-Oxley ... but the new section effectively disappears during the review process.

SHARE study cited vax/vms competitive advantage over vm/4300 as requiring less care&maintenance along with lower skill level. Big explosion in low & mid-range hit constraint of limited skilled resources ... and vax/vms had some competitive advantage over vm/4300. And as mentioned, Endicott also had to deal with internal politics with POK over vm/4341 encroaching on big datacenter market.
SHARE called for significant increase in "canned" operations for vm/4300.

One of the items is new governor of the New York Fed comes in the early part of the century and at one of their first NY FED advisery board meetings, Shiller explains how the real estate market is in big inflation "bubble" and will be due for burst. The new New York Fed governor replaces Shiller on the advisery board (part of allowing the bubble to reach truly epic proportions).

from above:
Instead, I see General Dunford's public remarks as the Marine Corps
leadership effectively shutting down discussion. Myself, I think it
would be smarter for the Marines to announce as soon as possible that
they are cutting to 150,000 -- and then go on to say, they aim to be
the nation's small-but-ready force, able to go into a conflict early
and buy some time for the country, not unlike Korea in the summer of
1950. This is the time to get creative, not the time to go into a
defensive crouch.

So who is right: Benson and Rotkoff or their detractors?
They both are, for they are, in fact, talking about two different

and Rotkoff call inadequate. The second, less familiar one was
designed by Boyd himself. For the last 20 years, the OODA-Loop has
increasingly driven our strategy, doctrine and force structure
decisions. And for most of that time, we've been using the
wrong one.

Two top Treasury officials, Neel Kashkari and Phillip Swagel, had
already created a memo on bailouts that they called the "Break the
Glass" Bank Recapitalization Plan -- a ten-page apocalyptic scenario
outline that would later provide the rubric for TARP. Its idea was
straightforward: Treasury would purchase toxic assets from the banks,
unwind them using a private-asset intermediary, such as BlackRock, and
then sell them to maximize value for the people who would ultimately
be on the hook: the taxpayers.

But in jan2009, they discover that appropriated funds for TARP isn't even 10% of what is needed ... so have to leave it to the FED and use TARP for other things.

I recently finished "Confessions of an EHM"
https://www.amazon.com/Confessions-Economic-Hit-Man-ebook/dp/B001AFF266
... hard to believe its not fiction ... but it has much being shifted
to corporations and their EHM, when the EHM fail, then they send in
the jackels, its only when the jackels fail, they send in the
military.
the book has EHM only partially profits, a major goal is leverage
EHM story is to convince countries to start massive infrastructure projects predicting benefits far in excess of possible. Country gets loans to pay for projects and companies skim massive profits. Country can't keep up with payments. US gov goes in and helps them restructure payments in return for special considerations.
EHM story has Venezuela being on the verge of a Panama type event ... EHM and the jackels had failed ... so the next step was the military, but Venezuela narrowly avoids the Panama fate because of 9/11 and excuse to send military into Iraq (instead)

http://www-03.ibm.com/ibm/history/history/year_1980.html
didn't break out, but mostly hardware ... it was possibly 81 or 82 when disk division said they had a year where they had more revenue than processor division
inflation factor:
http://www.usinflationcalculator.com/frequently-asked-questions-faqs/
cpi: 1980. approx. 80, 2q11. approx. 225 or approx. 2.8 times
the 1980 total revenue then is $73B in today's dollars or about $18B/qtr ... majority hardware compared to $4.7B for hardware 2q11 (hardware sales dropped by possibly factor of four times).
note in 1980, nearly all of the hardware sales were mainframe ... so the drop off in the mainframe hardware sales may be closer to an order of magnitude.
note that 1980 ... there was major internal programs to move off a large number of different microprocessors to 801/risc iliad chip; s/38 -> as/400 would use iliad, follow-on to 4331&4341 (aka 4361&4381) would use iliad, bunch of controllers would move to iliad. etc. For whatever reason, the iliad efforts floundered ... and company continuing business as usual with large number of different CISC micrprocessors (i.e. as/400 group quickly developed their own CISC when Iliad effort failed, 4361 & 4381 developed their own CISC, large number of different controllers continued with broad range of different CISC microprocessors).
there was the 801/risc ROMP chip (joint research & office products) that was going to be the follow-on to the displaywriter. When that was canceled ... they looked around and settled on retargeting the displaywriter follow-on to the unix workstation market. The company that had done the AT&T unix to PC/IX product was hired to also do one for ROMP ... which became PC/RT and AIX2.
Then RIOS chipset was done for follow-on unix workstation ... becoming POWER, RS/6000 and AIX3.
Then there was the joint Somerset effort with Motorola, Apple and IBM (also referred to as AIM) to do a single chip 801 ... as power/pc. Rochester got involved in the Power/pc effort and used the chip for (finally) moving AS/400 from custom CISC chip to 801/RISC chip.

mainframe clustering was called loosely-coupled ... multi-tailed disk on same machine room floor. used "reserve/release" semantics for whole drive/device ... done on os/360, asp (turns into jes3), hasp shared-spool (turns into jes2 shared spool), and airline control program (turns into tpf) ... 2314s for 360 machines ... then in the 70s, 3330 for 370 machines.
for the 3330, there was the ACP extensions for the 3830 disk
controller ... which supported semantics more like later VAX/VMS
hardware controller. recent discussion of loosely-coupled from 360/370
https://www.garlic.com/~lynn/2011i.html#77

trivia ... in the 70s, my wife had been con'ed into going to POK to be
in charge of (mainframe) loosely-coupled (aka cluster)
architecture. while there she developed Peer-Coupled Shared Data
architecture ... some past posts
https://www.garlic.com/~lynn/submain.html#shareddata
which didn't see a lot of uptake (except for IMS hotstandby) until sysplex. She didn't remain there long, in part because of the slow early uptake of her architecture and also because of ongoing battles with the communication group over having to use SNA for loosely-coupled coordination (there would be temporary truces where it was allowed that she could use anything she wanted within the walls of the datacenter ... but the communcation group had strategic ownership of *everything* that crossed the datacenter walls ... a major inhibitor both to mainframes playing in distributed computing environment as well as doing geographic distance clustering).
In our HA/CMP project ... some past posts
https://www.garlic.com/~lynn/subtopic.html#hacmp
I had coined the terms disaster survivability and geographic survivability to differentiate from disaster/recover. I was asked to a section for the corporate continuous availability strategy document ... but the section got pulled when both Rochester and POK complained they weren't able to meet the requirements
We were also working with Sybase, Informix, Ingres, and Oracle
... because they had portable platform implementations and all had
"cluster" support from their vax/cluster support (mainframe DB2 had
"loosely-coupled" but wasn't portable ... and the "portable" DB2, was
totally different base and didn't have cluster support). I did a lock
interface design that supported the vax/cluster semantics to make the
ports easier. However, at least Ingres also had a list of major
deficiencies in the vax/cluster cluster implementation ... which I was
able to "fix" since I was starting from a fresh implementation.
https://www.garlic.com/~lynn/submain.html#available
I also worked out some tricks that would allow synchronization of distributed logs after a recovery ... allowing cached modified records to be transferred between caches in cluster configurations (w/o having to first having to be written back to home position). Lots of people were apprehensive about such stuff ... so it was more than another decade before it was used.
On lots of the new stuff, we were constantly running into roadblocks from other parts of the company about being able to deploy ... especially the mainframe groups ... and so we decided to depart in 1992.

Airline Control Program did support "high availability" on 360
hardware and then 370 hardware. The reserve/release semantics were a
pain ... which was motivation for logical/fine-grain locking support
in the 3830 controller (for 3330 disks on 370).
https://en.wikipedia.org/wiki/IBM_Airline_Control_Program
Not released ... but in mid-70s the internal US vm/370 HONE
datacenters were consolidated at 1501 in silicon valley (next door to
current 1601 facebook hdqtrs ... which are in the process of moving
into the old SUN campus). For the consolidated US HONE datacenter we
did do multiple loosely-coupled (cluster) high-availability/fallover
as well as load-balancing across available processors. Note that some
of the virtual machine based commercial online service bureaus had
previously done a couple yrs earlier, high-availability fall-over for
vm370. This was behind first part of my note in 2009 "From The Annals
Of Release No Software Before Its Time") ... when cluster z/VM support
was released
https://www.garlic.com/~lynn/2009p.html#43
https://www.garlic.com/~lynn/2009p.html#46
the late 70s HONE made do w/o reserve/release and w/o the ACP 3830 fine-grain locking ... a special CKD search/write channel program was used that simulated multiprocessor compare&swap semantics. Read a record of lock locations, update values, and then do search-equal on the original record, if successful, rewrite the record with new value, if failed, reread the record. There was also discussions in the late 70s of JES2 using the scheme in the JES2 loosely-coupled implementation ... w/o needing reserve/release.
The second part of "From The Annals Of Release No Software Before Its
Time") was 2009 benchmark of power/db2 clustering with 100 nodes in
cluster ... which we had been working on in '91 & '92 before leaving
... some old email
https://www.garlic.com/~lynn/lhwemail.html#medusa
and this reference to jan92 meeting in Ellison's conference room
https://www.garlic.com/~lynn/95.html#13
Note that after earthquake in northern cal., in early 80s, the 1501 location was replicated first in dallas and then a 3rd in boulder ... with load balancing and fall-over between the 3sites.

for topic drift, the compare&swap instruction was originally invented
by charlie when he was doing multiprocessing locking work on (virtual
machine) cp67 at the science center (CompareAndSwap was chosen because
CAS are charlie's initials) ... misc. past posts mentioning science
center
https://www.garlic.com/~lynn/subtopic.html#545tech
then there was an attempt to get compare&swap included in 370
architecture. It was initially rebuffed because the POK favorite son
operating system people said it wasn't needed. The 370 architecture
owners then offered challenge that to get compare&swap into 370 would
require coming up with uses other than multiprocessor
locking/serialization. Thus was born the description for use of
compare&swap by multithreaded applications ... which has appeared in
appendix of every (mainframe) principles of operation since that
time. Other platforms also started implementing compare&swap (or
instruction with similar semantics) and most large multithreaded
applications started using it (including most RDBMS implementations).

other trivia ... original sql/relational implementation was system/r
done in bldg.28 on vm370 370/145 ... some past posts
https://www.garlic.com/~lynn/submain.html#systemr
there was then technology transfer from SJR/bldg.28 to Endicott for
what became SQL/DS. there have been lots of folklore that SQL/DS was
allowed to escape because the corporation and POK favorite son
operating system was getting out the new official product EAGLE. When
EAGLE failed ... there was then was mad rush to see how fast sql/ds
(aka system/r) could be ported to MVS (for release as DB2) ... one of
the (oracle) people mentioned in this jan92 meeting
https://www.garlic.com/~lynn/95.html#13
claimed to have done the majority of the SQL/DS technology transfer to
STL for DB2 (when he was at STL).
During the 70s and system/r development ... there were skirmishes between IMS group in STL. The IMS group pointing out that System/R required twice the physical disk space and possibly five times (or more) the number of disk i/os (to access a record, reading various index levels). The rejoinder was that there was enormous people time spent maintaining&administrating IMS (because record pointers were logical exposed to applications).
The 80s brought cheaper disks ... mitigating doubling disk space, much larger processor memory ... allowing indexes to be cache (reducing extra disk i/os) ... and people skills & resources became scarcer and more expensive .... tipping tradeoffs for lots of applications from IMS to RDBMS.
cics trivia ... when I was undergraduate in the 60s, the univ. library
got ONR grant to do online catalog ... they used part of the money to
get 2321 datacell. they were also selected to be one of the betatest
sites for the original CICS product ... and I got tasked to
debug/support the deployment ... got to shoot&fix early CICS bugs. One
of the early bugs was that the library was using different BDAM
options than had been used by the customer where cics was original
developed ... which took a couple days to shoot the internal
dependencies. misc. past posts mentioning cics &/or bdam
https://www.garlic.com/~lynn/submain.html#cics
PROFS triva ... the PROFS group had picked up a very early copy of
internal email client called VMSG (like version 0.6 or some such) and
put menu wrappers around it. Later when the VMSG author had vastly
improved it for initial release ... he offered the much improved
version to the PROFS group. Their re-action was to attempt to get the
VMSG author fired (claiming what was in PROFS was not a very early,
limited function version of VMSG). The whole thing went quiet after
the VMSG author showed that every PROFS note in the world carried his
initials in a non-displayed control field. After that the VMSG author
would only share the source with two other people. Some old email
mentioning VMSG email client (I was one of the two people that
continued to have access to the source):

Markey recalled, "and that they'd figured out how to turn the investing of others people's money into a kind of game, where they were constantly changing the rules in a way that was subtly fraudulent, against the basic principles of fairness or fiduciary duty. He said that with this much money to be made for doing very little, it was worth the risk of getting caught doing what you had to do, but that they were working on lowering that risk as well, with lawyers working overtime to make sure many of these activities were legal, or at least hard to prosecute." After an hour, Markey said that he and the committee members had heard enough and asked the felon what might be done. Levine, sucking on his shake, thought this over for a minute or two, and then said, "You need to send out a slew of indictments, all at once, and at three p.m. on a sunny day, have Federal Marshals perp-walk three hundred Wall Street executives out of their offices in handcuffs and out on the street, with lots of cameras rolling."

one of the issues was JES2 used NJE ... but then design had huge
number of limitations ... including MVS/JES2 systems had different
release levels would result in system crashes. The internal network
technology had a significantly better design. One of the results, it
could accommodate/support different interfaces ... including
NJE. Because of the enormous number of JES2/NJE problems, such systems
were restricted to boundary/edge nodes while the main part of the
internal network operated with VNET/RSCS. A growing library of
VNET/RSCS NJE drivers eventually came about ... with special driver
for each specific release of JES2/NJE and included support for
translating NJE control information between release levels (to keep
MVS/JES2 systems from crashing). There was infamous case of San Jose
MVS/JES2 system causing Hursley MVS/JES2 crashes and it was blamed on
the local Hursley VNET node (because they hadn't put in the updated
software filters to keep MVS/JES2 from crashing). misc. past posts

Even though native VNET drivers were significantly better, including higher throughput than NJE drivers, eventually the product was required to only ship the NJE drivers (although internal nodes could continue to operate the much better native VNET drivers).
some of the early online computer conferencing came to be known as
Tandem Memos ... from ibmjargon:
[Tandem Memos]
n. Something constructive but hard to control; a fresh of breath air
(sic). "That's another Tandem Memos." A phrase to worry middle
management. It refers to the computer-based conference (widely
distributed in 1981) in which many technical personnel expressed
dissatisfaction with the tools available to them at that time, and
also constructively criticized the way products were [are]
developed. The memos are required reading for anyone with a serious
interest in quality products. If you have not seen the memos, try
reading the November 1981 Datamation summary.

and also from ibmjargon
[MIP envy]
n. The term, coined by Jim Gray in 1980, that began the Tandem Memos
(q.v.). MIP envy is the coveting of other's facilities - not just the
CPU power available to them, but also the languages, editors,
debuggers, mail systems and networks. MIP envy is a term every

From: lynn@garlic.com (Lynn Wheeler) Date: 15 Dec, 2011 Subject: Migration off mainframe Blog: IBM Historic Computingre:
discussion in mainframe experts group
http://lnkd.in/2syFGU
I've mentioned a number of times that in the wake of the failure of
future system there was a mad rush to get stuff back into the 370
product pipeline (during future system period, internal politics was
killing off lots of 370 activity viewed as competitive).
https://www.garlic.com/~lynn/submain.html#futuresys
During the future system period, I continued to work on 360/370 stuff
and even periodically ridicule future system stuff ... and provided
production systems to internal datacenters ... old email about
migrating stuff from cp67 to vm370 base and making "csc/vm" available
to internal datacenters:
https://www.garlic.com/~lynn/2006v.html#email731212
https://www.garlic.com/~lynn/2006w.html#email750102
https://www.garlic.com/~lynn/2006w.html#email750430
because of the mad-rush ... some amount of the stuff was selected for inclusion in vm/370 release 3 ... and then other stuff was selected for release as my "resource manager" (which was also the guinea pig for starting to charge for kernel software).
Also in the spring of 1975, a group from POK con'ed me into working on
design for 370 5-way multiprocessor (which never shipped) ... some
past posts
https://www.garlic.com/~lynn/submain.html#bounce
... and concurrently Endicott con'ed me into helping them with
microcode assist for virgil/tully (would become 138/148) ... old post
about tests that were used to determine what went into ECPS:
https://www.garlic.com/~lynn/94.html#21
basically 138/148 had 6kbytes of available microcode store. the 138&148 engines simulated 370 at approx. 10native instruction for every 370 instruction. 370 kernel stutff could drop pretty much into native on 1-for-1 byte ... giving nearly 10 times speedup. The trick was to identify the highest executed 6kbytes of the vm370 kernel for dropping into native instructions.
Endicott also con'ed me into periodically running around the world being part of one-week sessions with business planners in different countries forcasting the market for 138/148. Endicott also attempted to create a vm370 product with 138/148 .... making vm370 part of every machine shipped and as transparent as possible to the customer (something like modern day LPARS) ... however they were overruled by corporate hdqtrs (dominated by POK high-end and POK favorite son operating system ... that was in the process of trying to get vm370 killed off) and got their hands slapped for trying.
the 4331/4341 were then the follow-on to 138/148.
This describes some of the ins&outs of the 303x and 3081
http://www.jfsowa.com/computer/memo125.htm
In POK mad rush to get stuff back into the 370 line, they started 303x and 3081 concurrently.
the 303x was basically 1) 303x channel director, 370/158 engine with integrated channel microcode and w/o 370 microcode, 2) 3031, 370/158 engine with just the 370 microcode and w/o integrated channel microcode; configured to work with external channel director, 3) 3032, 370/168 with new covers, 4) 3033, 168 logic mapped to 20% faster chip; some late optimization gets it up to 1.5times 168 performance.
the 3033 attempts to do some ECPS type things ... the problem is the 3033 native engine was horizontal microcode and was already doing effectively 1:1 native to 370 instruction ... so move from 370 to native had negligible effect ... and in some cases actually introduced additional overhead.
As described in the sowa reference ... 370/xa and 3081 was going on in parallel with 303x effort. Also, head of POK convinced corporate hdqtrs to kill the vm370 product, shutdown the vm370 development group in Burlington Mall and move all the people to POK ... or otherwise he wouldn't be able to meet the mvs/xa delivery schedule. Endicott eventually managed to save the vm370 product mission ... but had to reconstitute a development group from scratch (which resulted in some amount of quality problems during the late 70s and early 80s ... which can be seen in various vmshare postings).

we complained bitterly about change from 3272/3277 to 3274/3278 ...
lots of the electronics were moved out of the terminal head back into
the controller for 3274/3278 (reducing manufacturing costs) making it
impossible to meet requirement for .2 second response. also because of
electronics in the head of 3277 it was possible to do some hack of
electronics to make 3277 a little more friendly for interactive
computing (eliminate keyboard lock when typing at the moment screen
updates, changing repeat key delay & rate) ... old post with benchmark
numbers from when 3278 was first introduced:
https://www.garlic.com/~lynn/2001m.html#19
eventually, kingston came back and said that 3278 was targeted for dataentry, not interactive computing.
MVS/TSO were attempting to dispute that even sub-second response didn't make any difference (not to mention .2 second) ... since most MVS/TSO systems were even lucky to meet 1second response. There was then a number of internal human factors studies showing subsecond response does improve productivity.
from ibm jargon:
bad response - n. A delay in the response time to a trivial request of a
computer that is longer than two tenths of one second. In the 1970s, IBM
3277 display terminals attached to quite small System/360 machines could
service up to 19 interruptions every second from a user I measured it
myself. Today, this kind of response time is considered impossible or
unachievable, even though work by Doherty, Thadhani, and others has
shown that human productivity and satisfaction are almost linearly
inversely proportional to computer response time. It is hoped (but not
expected) that the definition of Bad Response will drop below one tenth
of a second by 1990.
... snip ...
bad response characteristic was why large amount of internal development was done on vm370/cms systems ... regardless of the target platform the development was being done for.
I fielded interactive systems that had 90th percentile .11 trivial response ... coupled with 3272/3277 hardware response yielded .196 "user" responses.
The move of electronics back into the 3274 controller also significantly increased the coax protocol chatter between 3274 and 3278 ... as well as putting additional processing load on 3274. channel attached 3274 also exhibited significant channel busy (far in excess of pure data transfer) ... interfering with performance of anything else that might be on the same channel.
Later with ibm/pc terminal simulation ... 3277 simulation would have three times the upload/download thruput as 3278 simulation (because of the big increase in 3274/3278 coax protocol chatter).

from above:
Speculators have taken a lot of the blame for the collapse of housing
prices and the subsequent financial crisis, but evidence to support
the charge has been scant.
... snip ...
unregulated loan originators being able to unload by paying for triple-A rating on packaged mortgages as toxic CDOs, no longer had to care about borrower's qualifications or loan quality. speculators getting no-doc, no-down, 1% interest only payments could make 2000% ROI in parts of country with 20-30% real estate inflation

and instead of appointing the A-team ... appointed the B-team (many who were instrumental in the economic crisis and in the Japan-or-Sweden strategy choice, chose Japan)
Jan2009 I was asked to HTML'ize the recently scanned Pecora hearings,
extensive x-link HREFs and HREFs between what happened last time and
what happened this time (Brokers' Loans and mortgages/triple-A rated
toxic CDOs) ... some asssumption that the new congress had appetite to
do something. After a couple months, I got a call that it wasn't
needed after all (enormous funds being poured into capital by
wallstreet)
BROKERS' LOANS AND INDUSTRIAL DEPRESSION
For the purpose of making it perfectly clear that the present
industrial depression was due to the inflation of credit on brokers'
loans, as obtained from the Bureau of Research of the Federal Reserve
Board, the figures show that the inflation of credit for speculative
purposes on stock exchanges were responsible directly for a rise in
the average of quotations of the stocks from sixty in 1922 to 225 in
1929 to 35 in 1932 and that the change in the value of such Stocks
listed on the New York Stock Exchange went through the same identical
changes in almost identical percentages.
... snip ...
The GSEs use to buy mortgages directly from the lenders ... and then the lenders found that they could package mortgages as toxic CDOs and pay for triple-A ratings and immediately unload (the enormous fees and commissions on $27T in triple-A rated toxic CDOs transactions was major source of wallstreet income during the bublbe, which wallstreet encouraged). There was article that at the height of the bubble, the GSE share of the mortgage market had been cut in half (in part because they still had rules preventing them from dealing in the kind of mortgages being stuffed into triple-A rated toxic CDOs).
"Confidence Men: Wall Street, Washington, and the Education of a President" has a note that Blackrock is managing $5.5T in GSE triple-A rated toxic CDOs ... a question is how/when did all the toxic CDOs show up on the GSE books ... also has item that GS started seeing triple-A rated toxic CDOs coming through fairly early in the bubble with mortgages that never had a payment; apparently part of the motivation, after selling to their customers, they would turn around and take CDS bet that the CDO would fail.

peers.

ust now on the ibm-main mailing list:
One Less Mainframe Shop
http://groups.google.com/group/bit.listserv.ibm-main/browse_thread/thread/8d3cd644614bda1b#
note that the referenced ibm-main post talks about 20yrs previously the whole company was run-off the mainframe. then there was still financial and some number of other things that recently were the last to leave. the implication was that financial and a few other small things were the hardest to migrate off the mainframe ... but the whole rest of corporate dataprocessing left the mainframe with much less effort. That implies quite a few things were possibly trivial to migrate off the mainframe and some things were much harder to migrate.
Lots of stuff runs into horrible problems migrating because nobody is left that has the faintest idea what it is. This is similar to motivation for the dire predictions about Y2K a little over a decade ago (y2k remediation could be considered trivial operation relative to magnitude of a major migration)
As to internet operation ... long ago and far away did comparison of
mainframe LU6.2 (and similar for TCP/IP VTAM implementation) where
pathlength was 150,000 instructions and 16 buffer copies (cache miss &
processor overhead for larger messages could be larger for the buffer
copies than the processor overhead for the instructions). This was
compared to some TCP/IP implementations on other platforms that had
less than 5000 (aggregate/total) instruction pathlength and some that
would do things with zero buffer copies (aka as pathlength was highly
optimized ... overhead for buffer copies was starting to dominate
processor utilization). past post in ibm-main on the pathlength
subject
https://www.garlic.com/~lynn/2008d.html#1
old posts about having done RFC1044 support for the pre-vtam,
mainframe tcp/ip implementation
https://www.garlic.com/~lynn/subnetwork.html#1044
In the wake of doing online computer conferencing, there was corporate task force to investigate the phenonema ... which somewhat resulted in officially sanctioned conferences/discussions and an official tool that supported both usenet-like and listserv-like operation (listserv was developed later on bitnet for online computer conferencing).
one of the "official" sanctioned discussion groups in the early 80s
was on the looming y2k problem. old post (by somebody else ... working
at houston nasa):
https://www.garlic.com/~lynn/99.html#email841207
originally posted in decade old Y2K thread
https://www.garlic.com/~lynn/99.html#24
part of the "break year" issue is kicking the can down the road on doing full implementation.
another somewhat outcome of getting blamed for online computing
conferencing on the internal network was somebody was paid to sit in
my office for 9months and take notes on how i communicated
(face-to-face, telephone, etc), they also went with me to meetings,
got logs of all my instant messages and copies of all my incoming and
outgoing email. Besides being a corporate report ... it also turned

recent post about big chip shop moving off 3081 to ten sun servers
... because the salesman threatened the account with problems if they
didn't do certain things

then senior chip engineers had started back on cp67 on 360/67 and then moved to vm370/cms and were happy with how it was adapting to changes ... until the salesman had his bit to say.
note that both workstations and PCs were taking over the low-end & mid-range computer market (i.e. follow-on to 4331/4341 which were 4361/4381 as well as follow-on vax models) with distributed computing ... lots of workstations as servers ... but as PCs increased in power ... they have now started to also take over the workstations (in much the same way that workstation/PCs took over low/mid-range mainframe).

given the stuff that has been slipped into recent bills ... one concern is what are hidden agendas. drug cartels, smuggling, money laundering, etc are already illegal. summer of 2010 there were whole series of articles about "moral hazard" of the too-big-to-fail ... they had been caught money laundering for drug cartels ... but there wasn't much the gov. could do since the gov. was already leaning over backwards to keep the too-big-to-fail in business.

I had effort I called HSDT (high-speed data transport) in the 80s
... involved T1 and higher speed links
https://www.garlic.com/~lynn/subnetwork.html#hsdt
... including with what was to become NSFNET backbone (operational
basis for the modern internet). ... some old email
https://www.garlic.com/~lynn/lhwemail.html#nsfnet
I was having some hardware being built on the other side of the
pacific ... friday before I was to leave for trip ... the communication
group announced a new "high-speed" discussion ... with the following
definitions:
low speed: <9.6kbits
medium-speed: 19.2kbits
high speed: 56kbits
very high speed: T1
monday morning on the other side of the pacific on the wall of
conference room:
low speed: <20mbits
medium speed: 100mbits
high-speed: 200-300mbits
very high speed: >600mbits
the communication group came out with a study ... justifying why they
weren't supporting T1 and faster speed links. The 37x5 product had
support for "fat-pipes" where multiple parallel 56kbit links can be
logical treated as single link. They surveyed customers with 2, 3, 4,
5, etc 56kbit link "fat pipes" and found the numbers quickly dropped
off at four and five with almost no "fat pipes" with more than five
56kbit links. Based on that, they justified that they didn't need a
product supporting T1 until well into the 90s. What they avoided
reporting was that T1 tariff was usually approx. the same as five
56kbit links ... customers wanting more than 200kbits went directly to
T1 and moved to non-IBM products ... trivial customer survey turned up
several hundred (at time when communication group was claiming that
there were zero).
I took a lot of heat in the fall of '86 giving a HSDT presentation at
the SNA ARB (architecture review board) meeting in Raleigh
... involved plans for a product that did real high-speed networking
but simulated archaic SNA protocols at the boundary (emulated 37x5 to
host vtams) ... part of that presentation in this old post:

My wife had earlier been con'ed into going to POK to be in charge of
loosely-coupled architecture (mainframe for "cluster") where she
created Peer-Coupled Shared Data architecture ... mentioned upthread
https://www.garlic.com/~lynn/2011p.html#76
she didn't remain long because of little uptake (except for IMS
hotstandby) until sysplex and ongoing battles with the communication
group that wanted to force into using SNA for loosely-coupled
coordination. some past posts
https://www.garlic.com/~lynn/submain.html#shareddata
so IMS
https://en.wikipedia.org/wiki/IBM_Information_Management_System
while it had hotstandby and could immediately "take-over" ... even
with replicated system at geographic distance ... it had enormous
problem with the huge bloated VTAM. this upthread post
https://www.garlic.com/~lynn/2011p.html#94
mentions huge VTAM pathlength and buffer copies for straight-line message. Session initiation (in fall-over case) was much worse. 60,000 terminal fall-over required re-establishing 60,000 sessions ... even on max'ed out 3090 ... could take 90-120 minutes; so while the IMS would be operational immediately ... the effective system availability might take a couple hrs for large configuration.
So some of the features in the spoofed 37x5 was that all resources were represented by being owned by another VTAM (spoofed vtam) and were replicated within the distributed network infrastructure. IMS hotstanby was interested in deploying the operation so as to immediately establish shadow terminal sessions at the hotstanby ... to avoid the 2hr "fall-over" elapsed time (in large configurations; this is something similar to what tandem was offering as standard feature).
other recent IMS reference ... 300 people from the IMS group were
being moved out of STL to offsite bldg ... and finding that "remote"
3270 back into the STL datacenter was totally intolerable ... I got
con'ed into writing support for (non-IBM) channel extender ... so
they had effectively the same "local" 3270 operation (as they had when
they were in the building):
https://www.garlic.com/~lynn/2011p.html#17
followup in above thread about other issues with 3274 controller
https://www.garlic.com/~lynn/2011p.html#19
also old email that when Jim was leaving SJR for Tandem and palming
things off on me ... one of the things was DBMS consulting with the
IMS group (totally unrelated to the work I did for them supporting
channel extender):
https://www.garlic.com/~lynn/2007.html#email801006
https://www.garlic.com/~lynn/2007.html#email801016
also mentioned in this recent post
https://www.garlic.com/~lynn/2011p.html#20
similar difficulty (w/vtam) was faced by the vm/4341-cluster product. they had done custom protocol to get high-throughput out vm/4341-cluster (using 3088/trotter). before product release they were forced by the communication group to move to a vtam-based infrastructure for cluster operation. A simple example of the vtam-bloat was a cluster-synchronization operation that had previously took a very small fraction of second, took over 30 seconds elapsed time in the vtam-based implementation.
so one of the issues in large web-based environment possibly involving hundreds of thousands of users ... is avoid the enormous vtam-bloat paradigm.

facebook reference to blog entry on the "looped back in" article
http://www.schaefersblog.com/OODA-isnt-simple-and-it-probably-shouldnt-be/
and my comment to the facebook post:
reminds me of several object/GUI programming efforts in the 90s to do industrial strength dataprocessing ... executives saw all sorts of glitz & bling in the prototypes ... but the efforts failed miserably in deliverying industrial strength dataprocessing. Part of the attraction was that the simple object/GUI implementations had a few days learning curve (compared to months for industrial strength) so a lot of executives appeared to believe they could move to commodity programmers.
aka light-weight doesn't mean that it is low-skilled. There are periodic references that it requires much more skill&effort to come up with KISS than something complex (corollary it isn't done when there isn't any more to add ... its done when there isn't anymore to remove)
slightly related (software) complexity (now behind some sort of
registration and/or totally gone but lives on at the wayback machine)
"The Frameworks Quagmire"
https://web.archive.org/web/20060831110450/http://www.software.org/quagmire/
2167A (near the top right in the above figure) typically required ten time the effort as standard industrial strength dataprocessing (which i've frequently shown can be ten times the development effort of typical web application).
In the late 90s, I held a number of sessions looking at increasing the tool sophistication ... requiring corresponding increase in learning curve and skills ... which would reduce the 2167A associated effort by a factor of five times (making it possibly only 2-3 times that of typical industrial strength dataprocessing effort).
and comments this facebook posting
http://zenpundit.com/?p=4905
One of the things periodically mistaken about Boyd and OODA-loops is devolving into sequential, serial process. Boyd would refer to all parts of OODA-loop operating concurrently and looking at topic from all possible facets (again concurrently). Decomposition is a valuable classroom tool, novices would tend to ordering issues and addressing them sequentially in rank order ... as opposed to multi-variant approach (which typically requires deep understanding of subject matter).
note, serial, sequential also opens up the speed metaphor (iterations/revolutions per-sec) ... continuous, concurrent nullifies that speed metaphor as part of OODA-loop (leaving efficiency & quality). There is computer analogy with more things moving from synchronous to asynchronous as part of increasing throughput.

the communication group eventually had to come out with a box for
handling T1 ... but rather than simulating 37x5 and adding a whole
bunch of new function (spoofing host vtams that the resources were
"owned" outboard) ... it simulated another vtam and CTCA connection to
the host vtam. The issue is that vtam/sna was designed for handling
huge numbers of slow-speed dumb terminals (not even networking

one of the issues with 3737 was that it was still limited to approx. 2mbits/sec aggregate thruput ... a "US" T1 is 1.5mbits/sec full-duplex (3mbits/sec aggregate) and a "Euro" T1 is 2mbits/sec full-duplex (4mbits/sec aggregate)
a little drift ... one of the major RISC benefits has been
throughput. x86 implementations now tend to have "RISC" cores with
conventional instructions decomposed into RISC "micro-ops" by hardware
(there is some indication that even mainframes have adopted some of
the strategy). reference:

One of the things periodically mistaken about Boyd and OODA-loops is devolving into sequential, serial process. Boyd would refer to all parts of OODA-loop operating concurrently and looking at topic from all possible facets (again concurrently). Decomposition is a valuable classroom tool, novices would tend to ordering issues and addressing them sequentially in rank order ... as opposed to multi-varient approach (which typically requires deep understanding of subject matter).
note, serial, sequential also opens up the speed metaphor (revolutions/sec) ... continuous, concurrent nullifies that speed metaphor as part of OODA-loop. There is computer analogy with more things moving from synchronous to asynchronous as part of increasing throughput.

Recently I saw on an APL disk in San Jose an announcement of something
called VMSHARE. It appears to be a repository of information for VM
users both in and out of IBM. I would greatly appreciate it if you
could send be any information you might have about it, such as how I
may get access to such information, and how I might make contributions
to it. I am a general user on a small VM system, I do have my own
copies of the IBMVM conferencing EXECs (if that is of any help) and I
am very interested in the opinions of users outside IBM as well as
developments in VM usage in general.
Thank you very much for your assistance,

I continued to do 360/370 stuff (even when future system was killing off 370 efforts) ... and periodically would ridicule future system activities.
after the demise of future system, there was mad rush to get stuff back into 370 product pipelines ... which motivated decision to release various bits & pieces of stuff that I had been doing. A small subset of the sharing stuff (w/o the paged mapped filesystem support) was including in vm370 release 3 as DCSS.
the following is exchange with the SPF group about trying to map SPF
into a "shared module" (as opposed to DCSS sharing).
Date: 11/07/79 14:53:27
From: wheeler
To: somebody in GBURG SPF group
The SPF module starts (begins) at location x'20000' and end somewhere
close to x'70000' (actually around x'6a000'). If I load and genmod
SPF it ordinarily creates a MODULE which starts at location x'20000'
and ends around x'6a000', i.e. those core locations are written to disk.
When I invoke SPF the SPF MODULE file is read into locations starting
at the start of the module (x'20000') and ending at the end of the
module (x'6a000').
--
Shared module support is an enhancement to VM and CMS which allows
specification at GENMOD time which segments (16 page groups) are to
be shared. The segments to be shared must be occupied by the module
being genmod'ed (i.e segment 2: x'20000' thru x'30000'; segment 3:
x'30000' thru x'40000', etc.).
--
Ordinarily I would LOAD SPF
GENMOD SPF
--
for shared modules I
LOAD SPF
reset module ending address to x'70000'
GENMOD SPF (share 2 3 4 5 6
LOAD SPF (origin 30000
reset module ending address to x'80000'
GENMOD SPF (share 3 4 5 6 7
there would not be any problems? since SPF is not storing into a
relative module core location (i.e. start of the 1st SPF module + x'0' bytes)
but into absolute location x'20000'.
and the response about why there were still problems: as an aside ...
1979 GBURG SPF group appeared to still be using all upper case

To: wheeler
From: somebody in GBURG SPF group
LYNN,
THANKS FOR SENDING THE DESCRIPTION OF SHARED MODULES. I HAVEN'T
STUDIED IT IN DETAIL, BUT DID READ THROUGH IT. VERY INTERESTING.
YOUR IDEA OF STARTING SPF AT 30000 INSTEAD OF 20000 WOULD AVOID
THE "SHARED" VIOLATION AS WE STORE INTO LOCATION 20000. HOWEVER,
THAT WILL NOT SOLVE ALL THE PROBLEMS. IN SPF, THE WAY WE DETERMINE
WHETHER WE ARE RUNNING IN THE USER AREA (TEST MODE) OR IN
DCSS, IS TO COMPARE THE ADDRESS OF THE FIRST PROGRAM (HAPPENS TO BE
NAMED SPF) TO THE VALUE '20000'. IF IT IS NOT THERE, IT IS ASSUMED
THAT WE ARE IN DCSS. THE IMPLICATION IS THAT SPF WILL NOT RELOAD
ITSELF FOLLOWING A FOREGROUND COMPILE, OR CMS COMMAND THAT USES
THE USER AREA. IF MY UNDERSTANDING OF "SHARED MODULES" IS CORRECT,
I AM AFRAID THAT, AT LEAST IN THE NEAR TERM, THERE IS NOTHING I
CAN DO THAT WILL PERMIT SPF TO OPERATE CORRECTLY IN YOUR SPECIAL
ENVIRONMENT. FEEL FREE TO WRITE OR CALL.

this was time when kernel ran in "real" address mode and the virtual machine (guest) ran in virtual memory address mode. it was possible to load virtual memory pointer in control register one and do a "load psw" instruction. The "load psw" performed switching from kernel mode to user mode, switching from "real" address mode to "virtual memory" address mode in single instruction ... aka switch from supervisor address space ("real") to guest address space ("virtual memory"), from kernel/supervisor to problem/user mode and from kernel instruction counter to user instruction counter in a single instruction. Both CR1 ... virtual address space pointer and CR6 ... virtual machine assist could be prep'ed while in kernel/real ... which become active when load psw switches from kernel/real to user/virtual.
later with 370/xa and 3081 ... there was objective to have the kernel running in its own virtual address space (rather than real). that created a problem with not having single instruction that switched 1) the CR1 virtual address space pointer, 2) from kernel mode to user mode, and 3) from kernel instruction counter to virtual machine instruction counter.
So SIE instruction semantics ... provided the single instruction mechanism that switched from kernel mode to virtual machine mode (variation on user mode), kernel virtual address space to virtual machine virtual address space, and to virtual machine instruction
In virtual machine mode ... lots of kernel mode operations ... instead of interrupting into the kernel (for simulation by virtual machine kernel) ... were executed according to virtual machine rules.
Amdahl extended the concept with hypervisor mode ... basically allowed for multiple concurrent guests supporting a specialized set of virtual machine operations ... that eliminated the need for virtual machine monitor (operations were supported by new hardware layer).
3090 then responds to the Amdahl competition with PR/SM which evolves into LPARs (logical partitions) ... a new hardware layer in the hardware w/o actually requiring a "software" virtual machine monitor. LPARs have been usually been restricted to having dedicated mapping between real memory to virtual memory and doesn't support virtual memory paging operations. Initially, if a virtual machine monitor was run in an LPAR ... SIE wasn't available ... since the SIE functions were being used by the LPAR hardware layer. Then they needed to expand the SIE complexity so that a virtual machine monitor running in a logical partition ... could also make use of SIE (two levels of SIE operation).

... also mentioned here
https://www.garlic.com/~lynn/2011p.html#82 Migration off mainframe
big part of ECPS wasn't just adding virtual machine mode to additional supervisor instructions ... but also moving parts of the virtual machine monitor into hardware layer. For the low&mid-range, 370 was simulated by vertical microcode (that ran avg. ratio of 10 native instructions to one 370)... doing a one-for-one instruction move into native micrcode got a 10:1 performance boost in executed function. Adding additional virtual machine mode to additional supersivor instructions ... eliminated having to interrupt into the kernel for software simulation.
In any case, the 3033 tried something similar for some functions which turned out to show little improvement ... in some cases actually worse performance ... since 3033 was already running approx. 1 370 instruction per cycle ... it didn't show equivalent improvement as on the vertical microcoded 370s (to gain improvement with additions to hardware layer required eliminating execution, not just moving the same execution from 370 to lower hardware layer ... that is why adding virtual machine mode to supervisor instructions helped ... since it eliminated an effective task switch into the supervisor for simulation and then task switch back).
Initial SIE for 3081 had an interesting but different problem. Future
System effort had been killing off a bunch of 370 activity ... then
with the demise of Future System ... some past posts
https://www.garlic.com/~lynn/submain.html#futuresys
there was a mad rush to get stuff back into the 370 (hardware &
software) product pipelines. Part of this was effectively kicking off
the Q&D 303x effort concurrently with 370/xa & 3081 effort (then when
303x was out the door, those people started on 3090 .. overlapped with
3081). some discussed here:
http://www.jfsowa.com/computer/memo125.htm
The head of POK managed to convince the corporation to kill off the (vm370) virtual machine product, shutdown the vm370 development in burlington mall and move all the people to POK, or otherwise he wouldn't be able to meet the MVS/XA (POK favorite son) operating system ship schedule.
Endicott (low&mid range, 138/148 follow-on 4331&4341) managed to save the
vm370 product mission ... but had to reconstitute a development group
from scratch. This resulted in vm370 quality problems during the late
70s and early 80s ... periodically mentioned in the vmshare archives:
http://vm.marist.edu/~vmshare/
A side gaff was senior POK executive telling HONE that there would be no
more vm370 on high-end (POK) machines ... HONE was virtual-machine based
online world-wide sales&marketing support ... using large number of
high-end 370s around the world ... old email:
https://www.garlic.com/~lynn/2007d.html#email790216
and then a couple days later, POK comes back and says the executive
was using the wrong flipcharts:

so internally in POK, as an aid in MVS/XA development ... they developed
the virtual machine facility called the VMTOOL and SIE (on 3081) which
could be used by the VMTOOL (to aid in MVS/XA development) ... this was
never intended to be released as a product. And SIE was never planned to
be available for customers ... and not particularly optimized for
anything except running MVS/XA in a virtual machine. One of the issues
was the 3081 had limited microcode space ... and for SIE startup and
shutdown ... there had to be a huge amount of microcode paging ... which
made SIE really slow. MVS/XA tended to run for long periods so the SIE
microcode paging for startup/shutdown was less of an issue ... but for
lots of traditional online "conversational" CMS virtual machine
operation ... SIE startup/shutdown could take longer than the actual
virtual machine execution. old email reference (SIE and paged microcode)

in this post
https://www.garlic.com/~lynn/2011b.html#70 vm/370 3081
They eventually decided to release VMTOOL to customers as a "migration aid" ... a lot of customers were running MVS on 3081s in 370 mode and not migrating to MVS/XA. There was hope that releasing the VMTOOL it would help customers in migration from MVS to MVS/XA (by being able to run both MVS and MVS/XA concurrently on the same machine). There then was a (high-end) faction that wanted to turn the VMTOOL migration aid into full blown virtual machine product (SIE & VMTOOL having originally just been targeted for only supporting a few number of concurrent MVS & MVS/XA virtual machines and *never* intended to do things like running virtual machine monitor in a virtual machine).
This turns into something of big internal politics when a single person
in rochester made the modifications to vm370 to support 370/xa ... and
his vm370 running in XA mode has significant better
feature/function/performance than the limited VMTOOL (however,
eventually the high-end politics with VMTOOL won out ... even tho it
wasn't the best solution)

so much of the remaining measurable virtual/lpar overhead is related to i/o simulation. mainframe I/O is performed by "channel programs" (that were executed with "real" addresses). the 360 virtual machine monitor, cp67 would simulate I/O by scanning the virtual machine channel program (that was built with virtual addresses) and making a "shadow" copy that substituted real addresses.
in the 60s, the "batch" operating systems established a convention that applications created channel programs and used "EXCP" (EXecute Channel Program) to pass it to the kernel for execution (with real addresses). When these platforms were moved to 370 virtual memory environment, EXCP processing faced the same problem as CP67, application programs running in virtual address space, were creating channel programs with virtual addresses ... which had to be converted to real addresses. Their initial implementation was to borrow the CP67 channel program processor (CCWTRANS) and hack it into the side of EXCP processing (possibly the major effort done to get these platforms running in virtual memory environment).
If you then ran one of these "virtualized" operating systems in a virtual machine ... EXCP processing would first make a copy of the application channel program and then invoke SIO ... and if it was running in virtual machine, the virtual machine monitor would then have to repeat the operation of copying the channel program replacing the addresses.
So one of the remaining LPAR high-overhead items is still handling channel programs (but note that the traditional guests ... running in a partition ... has already performed a similar operation that requires much higher overhead; this is the argument that if these guests were redone from scratch to rely on the LPAR processing ... the overall throughput would be significantly higher than their ancestors that ran on the "bare" iron).
3081s had a different issue with ACP/TPF (airline control program) and Amdahl competition. 3081 was initially only going to be available in multiprocessor version ... and ACP/TPF didn't have multiprocessor support (which had prospect of ACP/TPF customers moving to Amdahl which still offered single processor models).
Somewhat conincidental in the transition from vm/370 to vm/sp (where all kernel software was charged for), there was major rework of vm/sp multiprocessor support specially for 3081 customers with ACP/TPF production guests (and little other workload). Normal vm/370 multiprocessor support had majority of kernel simulation serialized with the associated virtual machine operation. In a 3081 scenario that was primarily running an ACP/TPF guest, only a single processor would be executing. Lots of additional multiprocessor kernel overhead was introduced in vm/sp specifically for ACP/TPF case to try and overlap some of the kernel privileged instruction simulation with virtual machine execution (specifically the case of I/O simulation which were allowed to be asynchronous). This increased the single ACP/TPF guest throughput and improved total utilization by making better use of additional processors. However, this turned out to be somewhat the case of lots of current desktop software not leveraging multi-core processors. The problem was that the majority of vm/370 multiprocessor customers were running large number of concurrent virtual machines ... already being able to achieve 100% utilization of all processors. The ACP/TPF multiprocessor changes introduced in vm/sp degraded the majority of customer throughput by 10-20percent.
370, 303x, and 3081 cache machines ... would slow the processors cycle down by 10% in two-processor version ... to accommodate cache being able to listen for cache (consistency) invalidates from the other cache (any actual invalidate processing would further slow throughput down) ... so a 2-processor multiprocessor only had 1.8 times the processor cycles as a single processor (aggregate throughput could be much less because of cross-cache invalidates/interference as well as multiprocessor software effects ... two-processor having possibly as low as 1.3 times the throughput of single processor).
The Amdahl competitive situation for ACP/TPF customers eventually resulted with the introduction of single processor 3083 ... which was a 3081 with a processor removed. Standard 3081 chassis had power/channels, etc in the bottom 1/3rd, processor 1 in the middle 1/3rd and processor 0 in the top 1/3rd. The simplest way of creating a 3083 would have been to remove processor one in the middle ... but that would have made the 3081 dangerously top-heavy ... so additional engineering was required to create 3083. Also since there was only a single processor cache ... the 10% processor slowdown could be eliminated (3083 processor being billed almost 15% faster than 3081 processor eliminating the 10% slowdown).

for some additional drift ... Burlington had something similar, some circuit programs implemented in Fortran. Base MVS had design point of 16mbyte virtual address space for each application ... but os/360 heritage had a pervasive pointer passing API ... so MVS kernel image occupied 8mbytes of every application virtual address space. There was also requirement for "common area" that was minimum of 1mbyte in every virtual address space (and for larger systems, could be 4-5mbytes and was in danger of moving to 5-6mbytes). Burlington's Fortran application was 7mbytes and in constant danger of exceeding that ... and Burlington had to go through all sort of hoops for corresponding MVS that just had a 1mbyte common area.
San Jose disk engineering also had similar applications that ran on MVS.
They had additional problem that computational demand was exceeding
datacenter floor space for high-end POK machines. They started effort to
put vm/4341s out in every departmental area and worked on additional MVS
simulation code for CMS ... that would allow the applications to easily
run in vm370/cms environment on large number of distributed vm/4341s.
some of this appears in this old 4341 related email
https://www.garlic.com/~lynn/lhwemail.html#4341
and Burlington was starting to express some interest since they could get nearly the full 16mbyte virtual address space ... when running under cms in vm370 virtual machine (eliminating the constant battle they were having with their application breaking the 7mbyte barrier ... and constantly having a tailored MVS system limited to 1mbyte common area).

one of the things driving start subchannel was enormous MVS pathlength in interrupt handling and device "redrive" ... and as I/O became larger & larger system thruput bottleneck ... there was lost thruput associated with operating system pathlength between end of previous i/o operation and start of redrive of the next i/o operation. start subchannel could define queued/pending operation that was immediately available for starting by independent external processor (when previous operation finished).

the purpose for IDALs was to provide scatter/gather that could be prefetched. Previously (in cp67), cp67 would create "shadow" channel program that simulated single channel command with argument that crossed page boundary (virtual address was consecutive but the corresponding virtual pages were located at non-consecutive real addresses). In order to handle this, CP67 had to translate one channel command into two or more "data chaining" channel commands (for each non-consecutive page crossing). channel programs are located in processor memory and defined that each channel command is processed serially with *no* prefetching (i.e. next channel command can't be fetched until previous finished). There were some number of instances where device timing were such that i/o operation would complete correctly when a single channel command was used ... but would fail if split into multiple data-chaining channel commands (overrun errors because the address wasn't available before data had to be transmitted). IDALs were introduced in 370 ... which were defined as list of non-consecutive addresses which could be "pre-fetched" (weren't subject to the serial non-pre-fetching processing restriction that came with channel command data-chaining).

there was some amount of dumb terminal processing that adapted the convention of modified channel program processing. Multiple chained channel commands for each device that reference allocated storage that was less than maximum possible that the device might transfer. Terminal i/o processing application would get a special interrupt when complete buffer had transferred ... it would then allocate some more storage and modify the active channel program to aditional commands for the additional allocated storage. The problem with virtual machine and EXCP channel processing for virtual environment ... was a completely different channel program would be dynamically created (with real addresses) and executed. Any modification to the channel program in the virtual address space (with virtual addresses) wouldn't be reflected in the channel program that was actually executing.
so a new kind of EXCP ... EXCPVR was defined for use by semi-privileged, appropriately authorized applications ... like VTAM. VTAM used interface to fix/pin some number of virtual pages in real storage. It would then create channel programs that referenced the real storage addresses (rather than the virtual addresses) and then invoke the EXCPVR system call ... which bypassed the EXCP virtual-to-real processing (also pin/unpin virtual pages for the duration of the i/o operation). This had the characteristic that when VTAM modified its own "active" channel programs ... it was modifying the one that was actually executing.

he had ported AT&T C to cms and made several performance enhancements and had ported numerous unix-based chip applications to CMS. One day, the IBM salesman stopped by and asked him what he was doing ... which was doing ethernet support to tie SGI graphics machines to ibm 3081. The salesman told him that he should instead be doing token/ring support ... and if he didn't, they might find that mainframe maintenance might suffer. Shortly afterwards I got a phone call that lasted for an hour or so with lots of four letter words. The next morning the customer had major press release that they were replacing mainframes with several SUN servers. This kicked off numerous internal corporate taskforces that treated the replacement of mainframe with SUN servers as a technical issue.

old 4341 related email
https://www.garlic.com/~lynn/lhwemail.html#4341
and being let to play disk engineer in bldg. 14&15
https://www.garlic.com/~lynn/subtopic.html#disk
old email about 4341 being fastest channels of the 70s ... with slight
tweak were able to support 3mbyte/sec transfers (aka 3880&3380 disks)
https://www.garlic.com/~lynn/2010e.html#email810617
above email also discusses other channels from the 70s (as well as other vendor disks and disk controllers).
disk engineering and product test tended to get early processor engineering machines (3rd & 4th ... after the processor engineering having machines). other old email mentioning I was doing benchmarking on disk engineering 4341 for the Endicott 4341 benchmarking group (because I had better access than they did).
disk engineering had been running mainframe processors "stand-alone" for testing. they had once tried MVS with objective of being able to support multiple concurrent tests ... but turned out MVS to have 15min MTBF in that environment (hang or failure) requiring reboot. I offered to completely rewrite I/O supervisor to be complete bullet-proof and never fail ... supporting anytime, on-demand, concurrent testing (significantly improving productive compared to 7x24 around-the-clock pre-scheduled, stand-alone testing).
part of the purpose of (370xa/3081) start subchannel was to help mask large MVS interrupt/redrive latency. one of the things that I did in the I/O rewrite in the 70s ... was to try and come as close as possible to 370xa redrive throughput with straight 370 code. It did contribute to having to resolve a 3880 controller problem.
Because my software changes was underneath all device testing ... whenever they had anomolous problems, I would get called to diagnose what was going on (whether or not it was actual software problem). One monday morning, bldg. 15 called to ask when I had done to the software on their 3033 processor ... that system throughput had gone totally down the tubes (they had very early engineering 3033, and since actual device testing took very small percentage of processor time ... they added a two 8-drive 3330s and spare 3830 controller to provide their own private online service). Even though they claimed to have made no changes, it turned out somebody had replaced the 3830 controller with new 3880 controller driving the same two 8-drive 3330 string ... and Monday morning, online response had went completely down the tubes.
Turns out that 3880 had a really slow processor for handling commands (compared to 3830) ... with a separate fast hardware path for data transfer (to support 3380 3mbyte/sec). They tried to mask how slow it was by signaling operation complete interrupt ... before it was actually finished (hoping to be done by the time the processor had processed the interrupt and attempted to redrive any queued operations). My pathlength was so short, that I was attempting to redrive queued request before the 3880 controller had actually finished. This required signaling SM+BUSY to the SIOF (controller busy) ... followed by CUE interrupt (control unit end). The additional interrupts and controller processing was also causing 3880 controller to slow down even further (for almost every I/O once monday morning activity picked up). The whole mess drastically affected system throughput. Fortunately this was still six months before first customer ship ... and they were able to do some addtional tweaks to 3880 controller (on off chance that regular operating systems at customer sites might accidentally be able to hit 3880 controller when it was busy ... when it shouldn't have been).

part of the US HONE scenario ... is providing online sales&marketing for all US sales&marketing, branch office, hdqtrs, etc ... with applications implemented in APL ... required significant processing ... more than any single large multiprocessor mainframe ... needed as many as possible as could be cramed into "1501" all running as single-system-image (late 70s). Claim in the late 80s, this had increased to 28 (two processor) 3081s.
Over the years, there was lots of pressure placed on HONE to convert
from vm370 to MVS .... all of which failed miserably. This is recent
post mentioning old email about a possibly frustrated, senior POK
(large mainframe) executive telling HONE that they would be able to
convert to MVS if they would just recode all the APL applications in
assembler:
https://www.garlic.com/~lynn/2011p.html#105
as things got faster and smaller ... latency and (fine-grain) global synchronization was becoming larger and larger problem. being able to use large number of commodity priced pieces resulted in all sorts of institutions being able to create massive computational complexes ... at least for those class of problems than can be parallelized.
At low level, shows up in transition with multi-core processors that can run asynchronously and simple multiprocessor parallelization becoming "holy grail". Old time multiprocessors could rely on large number of parallel, independent tasks to utilize resources. Now, increasing numbers of dedicated desktops, laptops, tablets, cellphones, etc ... all have multi-core processors. To leverage the resources requires new techniques to parallelize previously, purely sequential computations.
Recent post that includes discussion about trying to use a two
processor 3081 for dedicated sequential, serial operation. The
unnatural acts to try and use the 2nd processor ... for this small
subset of customers ... significantly increased the overhead for all
customer multiprocessor workloads (most of them that had already been
happily fully utilizing all processors in multiprocessor
configuration)
https://www.garlic.com/~lynn/2011p.html#115
3090 introduced "expanded store" that could sort of be used as paging cache. The issue was that physical packaging of memory couldn't get package sufficient memory close enough to the processor (with latency within operational requirements) to meet balanced 3090 system throughput requirements. The solution was to put some of the memory at longer distance (with higher latency) and have software explicitly move pages back and forth. The expanded store bus was really wide so the elapsed time for the move was less than typical path length to do asynchronous page operation (so it was more efficient to make the expanded store move-operations, synchronous instruction).
Later, changes in memory technology allowed sufficient storage to be packaged close enough to the processor to eliminate the latency problem. The expanded store feature hung around for some time ... being able to use LPAR magic to configure part of normal memory as simulated expanded store. The issue was that some of the page replacement algorithms didn't know how to efficiently manage larger amounts of memory all as standard paging ... so they operated better with some of the memory logically as expanded store (an appropriate page replacement algorithm treating all of memory as one large contiguous area would eliminate lots of the page faults requiring pages to be moved back and forth between expanded store).
One of the things in the 90s was people at SLAC pushing SCI as industry standard ... one of the application was simulated memory bus over uni-directional fiber links (data could move simultaneously in both directions) with directory-based cache consistency. Standard support was shared-memory 64-port caches. Sequent (later bought by IBM) did four (intel) processor boards with shared L2 cache and 64 boards for a 256-way Numa-Q shared-memory multiprocessor ; Data General did a similar 256-way implementation. Convex did a two (hp risc) processor board with shared L2 cache and 64 boards for 128-system Exemplar shared-memory multiprocessor (other vendors also used SCI for multiprocessor scale-up).

Boyd would use the term a few times in briefings ... translating it to
"finger-tip feel". One of the uses was describing a korean war
dogfight with one american and five migs ... and all six pilots
realizing approx. the same time that the american was about to shoot
the five migs down ... it was sort of like last moves of a chess game
where there would be checkmate regardless of the opponent's moves.

He also used it referring to after-action reviews of large scale wargames. He characterized the admirals/generals spending all year playing golf while their subordinates practiced. Then when it came time for the actual wargames, the commanders had no fingerspitzengefühl for the warroom.
He would hold his hand up with the tip of his thumb rubbing back&forth across the tips of his fingers.
One of the warroom/strategic scenarios is that information can be massive volumes and/or highly refined and abstracted. Lack of practice and familiarity can make orientation (finding meaning from massive volumes and/or highly abstracted) nearly impossible ... severely impacting quality of any decisions.
Similar, but different was Boyd's complaints about original headsup display for F16 ... presenting scrolling lists of digital numbers. The effort to translate the scrolling digital numbers into meaning resulted in poorer pilot performance (rather than better) ... advocating for information presentation that was more intuitive to pilots.
In the warroom situation the information was/is massive and/or abstracted ... in either case, people making decisions need lots of practice to orient (find meaning from the information) leading up to decide/act.

This is 2-3 decades old. In the early 90s, we did some work with very large mid-west state univ. They said most states were functionally bankrupt at the time (just moving budget around). As a result, they had already transitioned to 85% funding from state legislature to 11% funding from state legislature. They also said that in the period since late 60s, they had to dumb down entering freshman programs three times. In the wake of the 1990 census, there was report that half of the 18yr olds in the country were functionally illiterate (and projections that things would continue to get worse).

ibm 370/168-3 was 3mip machine. 155 had 2mic main store and 80ns cache. 155->158-3 got half-mic(?) memory and some other upgrades ... making 158-3 around 1mip.
This Whetstone benchmark (whetstone instructions/sec is somehow

http://www.roylongbottom.org.uk/whetstone.htm
has 155 at 0.465mwip, 158-3 at 0.826mwip, and 168-3 at 3.04mwip. However, it also lists 3033 at 5.6mwips ... when it was more like 1.5times 168-3 (i.e. 1.5*3=4.5mips).
It does have 4341 @.99mwips beating both 158-3 & 3031 ... which was similar to benchmarks i did. It has 4381 about same as 168-3.
It has vax 780s from about half that of 4341 to slightly more than 4341 (although not more than later 4341-2). PDP10 ranged from much less than 4341 to about that of 4341-2
science center got a 155-2 to replace 360/67 and got cp67 running in 370 mode. It was possible to unlatch the 155 front panel, swing it out and flip a switch that turned off the 155 cache ... which gave it approx. throughput of 145. I did that a couple times for benchmarks to get approx. throughput of 145.
now whetstone intel core i7 860 at 3.46ghz has 2790mwips ... nearly thousand times that of 168-3 .... but presumably 2790 is running four cores concurrently or about 698mwips/core ...

ibm 360/67 had 24bit real addressing and 24bit and 32bit virtual addressing modes.
ibm 370 had 24bit real and virtual addressing
ibm 3033 got a hack to physically address 64mbyte real storage. 370 page table entries were 16bits, 12bit page number, 2 defined bits and 2 undefined bits. It used a gimick to use the 2 undefined bits to come up with a 14bit (4096byte) page number ... allowing specification of up to 64mbyte ... even tho instruction addresses were limited to 24bit (16mbyte). IDAL addresses were also hacked to allow specifying 64byte real address (allowing paging into/out-of >16mbyte area).
vm370 kernel code (running in real) periodically had to address data
in virtual pages ... which might reside above the 16mbyte line. the
pok initial approach was to use IDALs to write-out pages (above
16mbyte line) and read them back into below the 16mbyte line. I gave
them a hack involving a dummy page table and some stub code that would
enter virtual addressing mode, do a MVCL from virtual address mapped
to real page above 16mbyte line to a virtual address mapped to real

3830 was horizontal microcode engine and significantly faster than the jib-prime used in the 3880 ... 3880 used separate hardware path for (3mbyte/sec) data transfer ... and it was the use of jib-prime that was the root of large number of 3880 performance issues.
one of the issues with the really slow jib-prime processing was that it significantly drove up channel busy time for every operation. The 3090 processor engineers had assumed that the 3880 would be 3830 with faster data transfer rate ... radically cutting channel busy (3830/3330 300kbyte/sec compared to 3880/3380 3mbyte/sec) ... and so designed for number of channels to support target disk operations/sec. When they became aware of how bad the 3880 channel busy was ... they realized that they would have to significantly increase the number of 3090 channels (and spread 3880 controllers across the larger number of channels). The increase in number of 3090 channels resulted in 3090 manufacturing needing another TCM (which wasn't an insignificant cost). There were jokes that 3090 product would bill the 3880 group for the additional 3090 manufacturing costs (basically offsetting the reduction in the 3090 profit margin against the 3880 controller group).
There was a lot of the engineers who were violently against using the jib-prime for 3880 because they knew how slow it would be ... they would attribute the decision to new executive that came out of accounting ... "bean counting" to drive down 3880 manufacturing cost ... even though it had a significant overall negative system impact.
All those extra 3090 channels were somewhat the start of the marketing line that mainframes had much higher i/o throughput than killer micros (when, in fact, the enormous number of mainframe i/o channels was to compensate for serious throughput problem; half-duplex design that was dedicated for duration of control operations).
360/370 channels had end-to-end handshake for every byte transferred. this contributed to channel length restriction of 200ft and about 1.5mbyte/sec transfer. 3880 supported "data-streaming" channels which would transfer multiple bytes for every end-to-end handshake. this increased max. channel length to 400ft and supported 3mbyte/sec transfers. However, control operations were multiple end-to-end transfers and channel busy would include 3880 processing latency.
Later much of fiber-channel, ssa disks, sci, etc ... were paired serial links transmitted asynchronously in both directions. control operations became packetized messages that ran asynchronously and eliminated half-duplex end-to-end hand-shaking latencies.

Opt-out says they can send/share stuff unless they can find on-file record that you object; "opt-in" says they can only send/share stuff when they have on-file record of your approval/authorization (there has also been some amount of evidence of institutions not-recording/not-filing opt-out requests). "opt-out" and "can-spam" significantly contribute to the volume of spam (increasing the difficulty of recognizing attacks).

From: lynn@garlic.com (Lynn Wheeler) Date: 28 Dec, 2011 Subject: Yes Virginia, Electronic Signatures Are Legal Blog: IBM AlumniWe were brought in to help wordsmith the cal. state electronic signature law ... there was a lot of politics going on with pressure to select/mandate a specific technology for electronic signatures. Part of this was during the internet bubble, some vendors were pushing business case on wallstreet that there would be $20B/annum revenue for specific technology ... requiring credentials that would go for $100/person/annum. When that didn't happen, the lobbying dropped off significantly. some past posts:
it has (also) been over a decade since cal. state electronic legislation. at the time, there was some expectation that the "silver bullet" for electronic signatures would be the mortgage business ... aka the loan originators were looking at significantly speeding up the process. It turns out that they transitioned to no-doc, no-down loans and frequently totally ignoring lending standards ... being able to pay for triple-A ratings on toxic CDOs eliminated any need to worry about borrowers qualifications or loan quality. Item in "Confidence Men: Wall Street, Washington, and the Education of a President" has a note that GS noticed fairly early in the bubble, triple-A rated toxic CDOs coming through with significant percentage of mortgages that *NEVER* had a payment (supposedly related to selling the triple-A rated toxic CDOs to their customers and then making CDS bets that they would fail).

From: lynn@garlic.com (Lynn Wheeler) Date: 28 Dec, 2011 Subject: Deja Cloud? Blog: Old Geek Registryre:
Original 370 virtual memory architecture had IPTE (selective invalidate individual page table entry) and ISTE (selective invalidate individual segment table entry) which could clear the corresponding entries in TLB ... which didn't make it into release. PTLB (purge all TLB entries) was the only thing that made it out.
Hardware retrofit of virtual memory support to 370/165 was running into problems ... and to gain back six month in announce/ship schedule ... several features of 370 virtual memory were dropped including IPTE and ISTE. All processors that had already implemented full architecture had to go back and remove the features dropped for 370/165. Also any software that had already implemented support using new features also had to change their implementation.
Included in features dropped was r/o segment protect. vm370 had already implemented cms shared segment protect using the new hardware feature. when it was dropped (as part of 370/165 schedule), vm370 had to go back and invent a real kludge in order to provide cms shared segment protection.
when a virtual guest is using virtual page tables ... the host vm370 creates a shadow page table (initially all entries invalid; that corresponds to the guest's page tables). when the guest goes to run using the virtual page tables ... the host vm370 actually runs with the shadow table (with 13 levels of virtualizing ... it is 13 levels of shadow tables).
The management of shadow page table entries is done using the rules for managing hardware TLB entries ... initially all entries are invalid, start running ... and only fill in an entry, one at a time as the shadow address space results in page fault. However, w/o any of the selective invalidate instruction ... any time there is any page table entry for any virtual address space ... that has to be invalidated ... vm370 then also has to issue a PTLB instruction. If the vm370 is a guest operating system, then according to PTLB rules, the next higher level (host) vm370 has to invalidate *ALL* pagetable entries in every possible shadow page table (that has been built for that particular guest vm370). Then since that vm370 has invalidated some shadow page table entries, it also has to issue a PTLB instruction. Which then requires the next level vm370 to invalidate all entries in all of its guest vm370 shadow page table entries ... and then also issue PTLB. This continues all the way up to the vm370 running on the real hardware.
The lack of selective invalidate instruction (IPTE) makes any twitch at any level in the virtualized environment create enormous work extending all the way back up the virtualized infrastructure ... making forward progress nearly impossible.
Normally in virtual, paging environment ... there is assumption that forward progress is made ... initially no valid pages, take page fault, make page valid, execute some more, another page fault ... until reasonable set of pages are valid and instructions execute for some period of time w/o page fault. The twitchy behavior of any page invalid operation resulting in PTLB, which in turn requires the whole shadow table infrastructure to be wiped clean (all the way back up to the top level vm370) ... and then things restart ... can make forward progress extremely difficult (aka it isn't the straight-forward, convoluted, shadow table virtual->real mapping at each level ... it is any PTLB for any reason, wipes it all out and things have to start all over again).

3033 and 3380 trivia
part of designing thin film floating heads for 3380 was air bearing simulation program. at the time the engineering 3033 was installed in bldg. 15 for disk testing ... the air bearing simulation program was running on the (MVT) 370/195 in bldg. 28 (SJR). The SJR 195 was running batch MVT with 2week to 3month jog turn-around ... even with priority classification ... the air bearing simulation was lucky to get 2-3week turn around.
turns out that even multiple concurrent disk testing took maybe 1-2percent of the processor ... that was one of the reasons it was setup for general online use for the engineers (and special friends; also leading up to having to diagnose problem when they swapped out 3830 controller for 3880 mentioned in previous post).
so the 370/195 had around 10mip for specially tuned code ... most code ran more like 5mips (because most branches drained 195 pipeline). The 3033 was only like 4.5mips (about 1.5times 168-3) ... but moving the air bearing simulation over to 3033 allowed it to get near real-time turn around ... potentially several times a day.

xmas message ... from vmshare archives:
http://vm.marist.edu/~vmshare/browse.cgi?fn=CHRISTMA&ft=PROB
which was social engineering attack ... convinces user to explicit execute the program ... which has hidden code that resends itself to everybody in the users nickname file.
recent post:
https://www.garlic.com/~lynn/2011i.html#4
also discussed that the bitnet xmas distribution was almost exactly a year before the morris worm ... which exploited vulnerabilities in tcp/ip apps to distribute itself
semi-related following post
https://www.garlic.com/~lynn/2011i.html#5
Lot of DDOS attacks result from first compromising huge numbers of
extremely vulnerable consumer machines ... giving rise to "BOTNETS"
(aka robot networks). Compromises are by exploiting vulnerabilities in
network applications (like morris worm), embedded code in network
files that are automatically executed by applications, and/or social
engineering (ala bitnet xmas exec, getting users to load &
explicitly execute compromised code).
https://en.wikipedia.org/wiki/Botnet
botnet use isn't restricted to DDOS attacks, they are also used for massive spam campaigns.
Up to the late 90s, majority of exploits were via vulnerabilities in
network related code ... primarily buffer length exploits related to
short comings in C-language programming. ... some past posts
https://www.garlic.com/~lynn/subintegrity.html#buffer
note that the original mainframe tcp/ip product was implemented in vs/pascal and had none of the buffer overflow problems that have been epidemic in C-language implementations
starting around the end of the century ... there was rise in exploits that relied on malicious code in network distributed files that would be automatically executed when the file was read (not requiring social engineering to convince user to execute the file). this was somewhat heralded at the '96 MSDC at Moscone in San Fran. All the banners proclaimed supporting the internet ... however the subtheme in every session was "preserving your investment". During the late 80s and early 90s quite a bit of applications grew up that supported adding executable code to application data files .... which would be automatically executed when application loaded the data file... for a network environment involving small, closed, safe business LANs.
This paradigm was then being moved directly to the hostile, anarchy of the internet ... with little or no countermeasures (one of my analogies was being shoved out the airlock in open space w/o a spacesuit ... if you didn't need a spacesuit on the surface of earth ... why would you need one in open space).
note that there was BITNET (& EARN ... univ. network using rscs
technology) ... misc. past posts mentioning bitnet/earn

Thinking, Fast and Slow by Daniel Kahneman (Nobel in economics)
pg.258:
"We find that firms with award-winning CEOs subsequently underperform,
in terms both of stock and of operating performance. At the same time,
CEO compensation increases, CEOs spend more time on activities outside
the company such as writing books and sitting on outside boards, and
they are more likely to engage in earnings management."
... snip ...
Earnings management is somewhat been applied to what Enron & Worldcom
did. Supposedly Sarbanes-Oxley was passed to prevent such happenings
(even sending executives to jail for problem financial filings)
... however, it required regulatory enforcement. Possibly because even
GAO didn't think SEC was doing anything, GAO started doing reports
showing uptic in problems with public company financial filings (even
after SOX). The explanation was that the fiddled financial filings
increased senior executive compensation ... and even if the filings
were subsequently corrected, executive compensation wasn't adjusted.
https://www.gao.gov/products/gao-06-1079sp
There was a report a couple years ago that said the ratio of US executive to worker compensation had exploded to 400:1 after having been 20:1 for a long period (and 10:1 in most of the rest of the world).
