US cycle was on 7-8 yr schedule, foreign competition had cut that in half and were in the process of cutting it in half again. Some number of technology vendors were invited in to participate ... including both the workstation and mainframe folks. I've commented before about (offline) chiding mainframe brethren participants, because (at the time) they were also on development cycle timeline comparable to US auto industry (which might limit any practical advice they might be able to offer).

The x9a10 financial standard working group had been given the requirement to preserve the integrity of the financial infrastructure for all retail payments. In the mid-90s, doing detailed end-to-end threat & vulnerability study of the payment landscape ... there were a couple observations ... some:
• security proportional to risk; the value of payment transaction to retail merchant can be a couple dollars while the value of payment transaction to transaction processor can be a couple cents ... In contrast, the value of the (information in a) payment transaction to an attacker can be the account credit limit &/or balance. As a result, an attacker may be able to outspend by a factor of 100 times attacking the system ... than merchant/processor can spend defending the system.
• dual-use vulnerability; payment transaction information needs to be readily available for dozens of business processes occurring at millions of locations all over the world. however, the knowledge of the account number may be sufficient to perform a fraudulent transaction ... and as such needs to be treated as something you know authentication ... and therefore is kept confidential and never divulged. the diametrically opposing requirements (readily available and at the same time, never divulged) implies that even if the planet was buried under miles of information hiding encryption, it wouldn't stop information leakage.

looting retirement funds have been done in various ways ... they are constant lucretive objective since so much money is involved. making promises to baby boomers boomers during their prime working years ... but running a pay-as-you-go retirement scam ... which basically says that the money isn't there when the baby boomers retire (effectively skimming the difference).
there is outright fraud ... basically straight stealing the money out of the accounts.
the recent financial bubble was sort of double whammy. we had been asked to look at how to value mortgage-backed securities in the late 90s ... being provided with some number of scams that had been used in the past (including gimmicks used during the S&L crisis). a big target for toxic CDOs was the retirement funds which were only investing in triple-A rated instruments. one of the big factors in the recent financial mess/bubble was being able to pay rating agencies for triple-A ratings on toxic CDOs ... even when the originators and the rating agencies knew that they weren't worth triple-A.

pin-debit transactions go thru the debit network to the issuing financial institution (whether they originate at ATM cash machine or at a retail terminal).
in the late 90s, there was some shift from credit cards to debit cards also being used at point-of-sale. this represented significant loss of revenue for issuers and associated networks. somewhat as a result, there are now "signature-debit" which have similar level of interchange fees as (signature) credit (in part because they have similar fraud levels) and transaction flows thru the association (credit) networks.
early part of the century there was walmart/merchant anti-trust
litigation against the associations regarding rules for signature-debit
cards. some url refs:

MasterCard Settles Wal-Mart Suit Over Debit Fees, Visa Will Fight
http://tech.mit.edu/V123/N22/debit_22.22w.html
There have been lots of skirmishes between retail merchant associations (& walmart) over interchange rates charged merchants (bascially discount taken on the transaction ... where merchants only see the transaction amount minus all the interchange fees).
GLBA which played significant roll in current financial mess ... for its repeal of glass-steagall (i.e. didn't create the risky transactions ... but allowed regulated depository institutions to have unregulated investment banking arms ... where the investment banking risky operations would put the whole institution at risk) ... had rhetoric on floor of congress that major purpose of GLBA was allowing institutions that were currently banks to remain banks ... but institutions that weren't currently banks couldn't become banks (specifically calling out walmart and microsoft).
part of walmart issue was if it got a banking charter ... then it could be its own "acquiring institution" ... and then collects its own significant "acquiring" part of interchange fee (that it has been paying to a few large acquiring financial institutions).
if walmart figured a way to issue cards to its own customers ... then it would collect its own significant "issuing" part of interchange fees. Then when walmart issued cards were used in walmart stores, it would be "on-us" transactions and eliminate the association part of interchange fee. since walmart represents something like 25-30% of retail transactions in the US ... that amounts to a whole lot of money in interchange fees its current providing to financial infrastructure.
debit cards with association "bug" on the card can be used for "signature-debit". if you have a "bugged" card .... only used it in pin-debit mode ... there is still possibility that the magstripe can be skimmed for creation of counterfeit card and crook using it in "signature-debit" mode. you have to specifically ask for a pin-debit only card.
there is some difference between credit and debit (whether pin & signature) with regard to gov. mandates on how institutions have to treat fraud (although most institutions will advertise that they will treat credit and signature-debit the same ... even if they don't have to ... in part because they are getting similar fees from merchants).
there has been more than decade push to deploy chipcards that would combat some of the fraud ... although some of the technologies have peculiar limitations. In the UK there have been complaints that incentive to merchants and financial institutions for deploying chipcard infrastructure was effectively to change the burden of proof in disputes (in the US, effectively merchant/bank in dispute with consumer has to prove consumer was responsible ... in some places deploying chipcard ... consumers now have to prove that they weren't responsible).

science center instrumented cp67 and started convention of gathering the stats at 5-10 min intervals ... eventually 7x24. this then propagated to other operations installing cp67. this eventually resulted in several years of data across multiple systems that profiled configuration, system operation, and workload profiles. this was then used in automated benchmark specification with synthentic workload ... to approx. real observed operations. with the transition to vm370 ... the number and variety of internal systems increased dramatically that data was being collected from.
recent thread in ibm-main discussing some of the operation and

some of it eventually evolving into things like "capacity planning"
previously mentioned was finally run of 2000 automated benchmarks that took 3 months elapsed time to run. the first 1000 were manually selected to cover operational and workload characteristics from wide variety of observed data.
in the above reference, one of the technologies mentioned was the
performance predictor ... and apl-based analytical model of system
operation. it had been deployed on world-wide HONE sales&marketing
support system ... allowing customer marketing people to input customers
configuration and workload profiles and then ask "what-if" questions
about what happens if workload &/or configuraiton changed (i.e. sell an
extra megabyte of memory). misc. past posts mentioning HONE
https://www.garlic.com/~lynn/subtopic.html#hone
in any case, a modified version of the performance predictor was adapted for automated benchmarks ... with the characteristic and result of each benchmark fed into the predictor. this helped calibrate the predictor (as well as helping calibrate my dynamic adaptive resource manager). for the final 1000 benchmarks ... the predictor was programmed to try and find anomolous operating points ... it would examine the benchmarks made so far and select a new combination of configuration and workload for the next benchmark, predicting what the result sould be. the result of the benchmark would then be compared against the prediction. then the process would repeat.

after my dynamic adaptive resource manager had been in customer shops for awhile ... I got a bug report ... I think from cornell. there was some code that every several minutes would calculate some activity avgs. there was sequence of 100 or so instruction that took the current TOD clock value and did some stuff. If somebody pushed the processor stop buttom while the processor was within those 100 instructions and left the processor stopped for at least 30 minutes ... before pushing the stop buttom ... there would be a (kernel) program check with divide error.
previous posts mentioning that 23jun69 unbundling announcement started

software should still be free
https://www.garlic.com/~lynn/submain.html#unbundle
during the process of getting ready to release my dynamic adaptive resource manager ... it was decided to make it guinea pig for charged for kernel software (plausibly because clone processors were starting to get market foothold as a result of the distraction of the future system effort).
vs/repack was finally released from the science center as a charged for (application) product the month before my resource manager. at that time, the company had policy that developers in "field" locations got the first month rental from every installed (charged-for) software application.
In the month between the release of vs/repack and the release of the resource manager ... the science center was redisignated as an internal location rather than field location (science center was officially part of the DPD sales/marketing division and was "field" location at MIT campus). the effect was that I was no longer eligible for first month rental from every installed resource manager. For some baroque internal political reasons ... they had decided to make the monthly rental of the resource manager nearly thousand dollars (per month). When the resource manager passed 1000 installed customers, I offered to forfeit my salary in return for the first month rentals.

3375 was to get some 3370 sales in MVS shops for the mid-range market ... since all the other operating systems managed to ship native FBA support (and 3380s were targeted for the high-end customer shops). vm/370 saw an enormous upswing in mid-range systems with 43xx machines ... some large commercial customers ordering multiple hundreds of 4341 at a time ... and installing them out in distributed environment like converted conference rooms or departmental supply rooms. vm370 4341+3370 and 4331+3310 fit nicely into that niche ... but represented much more of a barrier for mvs.
I've mentioned before offering native FBA support ... but response that I had to do $26M business case to cover cost of new (MVS) training and documentation (claim was that customers would just buy same amount of FBA as they were buying CKD ... eliminating incremental sales as business justification ... and I wasn't allowed to use long-term life cycle savings as business justification). This may have been just a side-effect of perception that much of MVS characteristics were so intertwined with CKD ... that FBA operation would violate some amount of MVS philosophy.

when some people science center came out to the univ in jan68 to install cp67 ... the cp67 group didn't quite trust the cms file system ... and so the cp67 source routines were os/360 files ... which had to be assembled on os/360 and generate real binary decks. the binary decks for the different kernel routines were then arraigned in card tray with bps loader on the front ... and the build for kernel image was booted from 2540 card reader. the build would load all the routines into memory and transfer to "savecp" routine which wrote memory image to disk in bootable form.
by the summer of 68, they were comfortable enuf with cms file system so that all the cp67 source had been moved to cms, assemblies performed on cms and binary card image files kept on cms. there was cms procedure that would "punch" an image (of what had been kept in the card tray) ... which then would appear in the virtual reader and booted. the kernel image was loaded from virtual 2540 reader into virtual memory and "savecp" wrote the memory image to disk (normally setup so that it was the disk used for real system boot).
moving to CMS allowed source updates to be done as "update" file rather than modifying the original source image. The convention had been base source started with 1000 and incremented each card by 1000. Update control statements referred to deleting, replacing and/or inserting using the sequence numbers in the base source files. The convention was that inserted/replaced cards would start out being in hundreds off the thousands number in the base ... i.e. if inserting a statement after 159000 ... the inserting "card" would have 159100 in its sequence field (the insert/replace sequence field numbers had to be manually typed)
I was doing so much source changes ... that I invented the "$" and a preprocessor program ... which would preread the "update" file ... look for update control statements with "$" ... strip off the dollar and then insert appropriate sequence numbers in any following cards. the actual update program then would work with a temporary file that was the output of my preprocessor.
Later ... my "$" preprocessor function was merged into the standard CMS update command. Also "update" option was added to source editing ... where the editor would take any changes ... and rather then saving a modification of the original file ... create an "update" file that when applied to the original file ... resulted in file image that corresponded to the changes that had been done during the edit session.
standard os/360 would distribute source image that roughly corresponded to major release ... but rarely was there system build from distributed source (except in case of some select subcomponents like HASP).
A standard os/360 build had a "starter system" ... maybe 50-100 cards (effectively all high level macro statements) were punched up (stage1 sysgen) that were assembled using starter system macro library. They specified macros that typically resulted in "punching" cards (stage2 sysgen, could be on the order of 2000 cards) that were various kinds of job steps that mostly specified copying binary image from the starter system libraries to new production system libraries.
Fairly early on, I had started doing customized os/360 stage2 sysgens ... by taking the "stage2" output card deck ... and carefully rearranging all the move/copy statements so that it resulted in optimal ordering of data on the resulting production system disks being built. The issue was that large parts of os/360 were quite disk intensive (limited real storage paradigm with program processing involving sequentially loading lots of little pieces) and as a result was quite sensitive to avg. arm seek distance. for the univ. workload, I could achieve nearly factor three times improvement in thruput by the careful ordering.
univ. sent me to fall68 SHARE user group meeting in Atlantic City ... where
I made presentation on some of the os/360 optimization work that
I had been doing ... as well as lot of cp67 rewrite that I had
been doing. old post with small part of that presentation:

are actually collected from internet/arpanet specific posts from 99 ...
https://www.garlic.com/~lynn/99.html
big change in the change-over to internetworking protocol on 1/1/83 was organized gateways that allowed lots of different networks to be interconnected ... significantly enabling growth in the number of interconnected nodes ... something that was much more difficult in the ARPANET environment with the homogeneous interconnection using IMPs.
I've claimed that the internal network technology had a flavor of
gateway in every node from just about the beginning ... which greatly
facilitated the internal network being larger than arpanet/internet from
just about the beginning until sometime late '85 or early '86.
https://www.garlic.com/~lynn/subnetwork.html#internalnet
the other big contributor to internet passing internal network in size
was the connection of large number of workstations (and growing number
of PCs). for various political reasons, there was lots of pressure that
only host mainframes appeared on the internal network ... and computing
devices appeared as various kinds of emulated terminals. misc. past
posts mentioning terminal emulation subject:
https://www.garlic.com/~lynn/subnetwork.html#emulation
a side issue with the internal network was that corporate dictates required all links be encrypted. In the mid-80s, there was claim that the internal network had over half of all the link encryptors in the world.
in the early to mid-80s it also represented a problem for my hsdt
project
https://www.garlic.com/~lynn/subnetwork.html#hsdt
having links running at faster than T1 ... since off-the-shelf link
encryptors were hard to find that handled more than T1 (and even just
plain T1 encryptors were quite expensive). This prompted an effort to
work on link encryptors that operated at much higher sustained rate and
were significantly cheaper than any T1 encryptors available on the
market (an issue that never really showed with either nsfnet backbone or
other internet links). some random old email mentioning encryption

disk division getting talk scheduled at the annual world-wide internal
communication group conference ... and started out the talk by stating
that communication group was going to be responsible for the demise of
the disk division. the issue was that communication group blocked
several disk division products that would have provided really
high-speed data access service to the distributed environment; the
communication group claiming that it had corporate strategic
responsibility for anything that crossed the wall of the datacenter.
The net was that lots of data was leaking out of the mainframe
datacenter to platforms that provided much better service for the
distributed environment.

claim was that renton was between $200m-$300m of ibm equipment (not all of it had been installed while I was there ... 360/65s were showing up faster than they could be installed ... with numerous uninstalled boxes constantly sitting around in the halls around the datacenter perimeter).
It is hard to imagine a datacenter with possibly ten times the ibm equipment that was in the renton datacenter.
that summer there was work on replicated renton datacenter up in everett. there was disaster scenario that if mt. rainier even slightly warmed up, it would melt ice&snow on the mountain, resulting in massive mud slide ... pontentially reaching renton datacenter. there were calculations that the cost to the company loosing the renton dataprocessing for a week was more than cost of the renton datacenter ... which justified duplicating renton dataprocessing up at the everett 747 plant (out of the path of the mt. rainier mud slide).
in any case ... as to difference between how pentagon measured success and how success might be measured in the field ... there is the adage about "follow the money". pentagon is closer to the fabled military/industrial complex and gold-plated beltway bandits. There was article a couple yrs ago about gold-plated beltway bandits (which can also be applied to military/industrial complex) titled the Success Of Failure. gold-plated beltway bandits realizing that in the long term, they made more money from failed projects than successful projects (large percentage were dataprocessing re-engineering of one sort or another at a billion or more per failed attempt).

From: Anne & Lynn Wheeler <lynn@garlic.com> Subject: Re: Was VM ever used as an exokernel? Newsgroups: alt.folklore.computers Date: Thu, 01 Jul 2010 08:35:36 -0400re:
for another example ... in the 80s ... I did an implementation moving the vm370 spool file support out of the kernel into a service virtual machine. the kernel based code was in assembler and tightly intertwined with lots of services provided to regular virtual machines.
my issue was that the networking support (running in service virtual machine) made heavy use of the vm370 spool file system. the spool file system internally managed data in 4k page-sized chunks (spool file and paging used some common support infrastructure) ... but was serialized/synchronized API (to the virtual machine) at those 4k boundaries. A spool file system might be doing 30-60 4k block transfers (/sec) ... aggregate across all virtual machine activity in a system. However, the networking virtual machine spool file activity would be interleaved with other virtual machine activity ... so it would only get 4-8 4k transfers/sec (20k-30k bytes/sec).
Some of the internal network backbone locations were starting to run into bottlenecks with multiple full-duplex 56kbit links; each full-duplex link requiring approx 10kbytes/sec capacity.
With HSDT ... having multiple full-duplex T1 and higher-speed links I
was having significantly more problems ... using the links for internal
network operation (I did other stuff for using links with tcp/ip
operation). A single internal network full-duplex T1 link required
approx. 300kbytes/sec sustained. For HSDT, I needed several mbytes/sec
thruput.
https://www.garlic.com/~lynn/subnetwork.html#hsdt
In any case, my vm370 spool rewrite moved to service virtual machine was done in vs/pascal ... added new API ... for moving virtual spool requests out of the kernel up into spool virtual machine and back. I had originally done paged mapped API on cp67 (for cms paged mapped filesystem) ... and was able to make use of that API for spool virtual machine. The paged-mapped API already had an asyncrhonous mode of operation that could be leveraged. However, to meet at least several mbytes/sec operation ... delayed contiguous allocation for asynchronous multiple 4k block writes had to be done for output into the spool system (on disk) as well as multiple 4k block asynchronous reads bringing them back in.
there was also some bells & whistles added for things like extra redundancy for failures recovery ... and signficiantly reduced elapsed time for failure recovery in worst-case failures.
the mainframe TCP/IP support was done in vs/pascal running in service
virtual machine. The original had very poor thruput consuming huge
amount of processor cycles. I did the changes to add RFC 1044 support
and in some tuning work at Cray Research (between cray and medium-size
370 mainframe) ran at mainframe channel thruput with only modest cpu use

there was something of blame-game in the press in the first part of this century regarding proliferation of signature-debit.
long ago, magstripe credit cards had vulnerability where crooks would fabricate counterfeit cards using simple formulae that was used for checking valid account numbers ... basically creating some number of cards with account numbers that passed simple valid number check. the idea was that just random distribution ... some number of the cards would specify a real, valid account number and fraudulent financial transaction would go thru.
industry eventually developed a account number guessing countermeasure ... which was a secure hash added to the magstripe. it basically was a static value that hashed some of the other information on the magstripe (primarily account number), encoded it with bin/bank "secret" (aka key), and truncated it before encoding it on the magstripe.
pin-debit ATM cards never really had to develop a corresponding
countermeasure becuase it already had two-factor authentication
i.e. card as something you have authentication and PIN as something
you know authentication ... from 3-factor authentication model,
some past posts
https://www.garlic.com/~lynn/subintegrity.html#3factor
where multiple authentication factors are considered more secure because the different factors are assumed to have different compromises (not to have common compromise).
In any case, the PIN acted as countermeasure to counterfeit card
built just from account number guessing (and didn't need the secure
hash) ... wiki card security code page
https://en.wikipedia.org/wiki/Card_security_code
above mentions field carrying the value in ISO8583
https://en.wikipedia.org/wiki/ISO_8583
however, with starting to enable ATM cards for signature-debit ... not needing PIN ... they became vulnerable to counterfeit card magstripes generated from account number guesses. In any case there were several press/news items a few years ago about how the ATM industry had less secure cards than credit industry (because they never evolved the secure hash feature on the magstripe).
the issuing institution validates the secure hash field from the electronic transaction ... using the bank/bin level secret used to encode the information. the association networks also have a "stand-in" feature where they have table of all the bin/bank secrets from all the issuing members ... to do a pre-validation of electronic transaction as it passes thru their network.
It was somewhat fluff and show ... because the crooks had pretty much moved on to skimming compromises ... where the full static data from valid magstripe are recorded for the generation of a counterfeit card (including any secure hash).

some thread between ha/cmp & cluster scale-up ... electronic commerce, and retail financial transactions.
ha/cmp posts
https://www.garlic.com/~lynn/subtopic.html#hacmp
some cluster scale-up email
https://www.garlic.com/~lynn/lhwemail.html#medusa
and then there was this meeting in early jan92
https://www.garlic.com/~lynn/95.html#13
we depart by that summer ... and two of the other people mentioned in
the jan92 also depart. they then show up at a small client/server
startup responsible for something called the "commerce server" ... and
they want to do payment transactions on the server. The small
client/server startup also had invented some technology they called
"SSL" they wanted to use. we were brought in as consultants for the
payment transactions ... as well as mapping "SSL" technology to payment
transaction business processes. part of the effort included a gateway
that sat on the internet and acted as interface between webservers on
the internet and bank/payment networks. some past posts
https://www.garlic.com/~lynn/subnetwork.html#gateway
the result is now frequently referred to as "electronic commerce".
somewhat as a result of the "electronic commerce" work, in the mid-90s we were invited to participate in the x9a10 financial standard working group ... which had been give the requirement to preserve the integrity of the financial infrastructure for all retail payments. That is ALL as in point-of-sale, attended, unattended, low-value, high-value, face-to-face, internet, cellphone, transit turnstile, debit, credit, merchant stored-value, gift cards, aka ALL.
Part of the x9a10 effort required during detailed end-to-end threat & vulnerability analysis of the various environments.
One of the challenges was looking at some of the smarcard activity that involved point-of-sale "contact" payments ... sort out various vulnerabilities and being able to have higher security ... but also apply it to internet & cellphone environments ... as well as make it work within the power and elapsed-time constraint of contactless operation at transit-turnstile.
there was a transit meeting in the 90s where one of the contact cards was asked how it would be made to work in a transit environment. Basically they came up with a "sleeve" and a 15ft electro-magnetic tunnel leading up to every turnstile ... people would be required to walk slowly thru the "tunnel" leading up to the transit turnstile ... with the contact sleeve acquiring sufficient radition power within the tunnel to drive the payment card and perform the transaction. this is compared to standard contactless card that is swiped within a few inches of the reader/power and performs the transaction within small fraction of second (using the power it is able to acquire being near the reader in that short swipe period).
misc. posts about some of the x9.59 standard work in the x9a10 financial

greenspan was on this morning trying to explain why the fed just miscalculated.
the issue had been that business & consumer loans were an infrastructure that intertwined the fed and regulated depository institutions ... with the fed being able to exercise lots of control over their leanding, interest rates, etc.
there was a small, relatively side area involving securitized loans which involved lending outside the traditional regulated environment (where FED exercised some control) ... but it wasn't significant market; in part because there was lots of skepticism about the quality of the instruments. they had been used during the S&L crisis to obfuscate underlying value (we had been contacted in the late 90s looking at doing valuation and various kinds of fraud detection related to securitized mortgages).
all of that changed this century when unregulated loan originators discovered that they could pay the rating agencies to get triple-A ratings on toxic CDOs (securitized loans). this blew open the market from billions to tens of trillions ... with all sorts of parties playing with triple-A rated toxic CDOs. the unregulated loan originators found they could sell off every loan they could originate ... without regard to the loan T&Cs, interest rate, loan quality, borrowers qualifications, etc. The only thing limiting their take was how big were the loans and how fast they could make the loans (they were taking percentage of every loan based on on loan value ... w/o regard to any other considereation).
this permeated out across the world with people dealing in toxic CDOs taking a percentage of their value ... and nobody paying any other attention because of the triple-A rating.
This was outside the FED control and pretty unaffected by things like FED rates.
It perculated back into the regulated depository institutions in number of ways. GLBA had repealed Glass-Steagall ... so that "safe" regulated depository institutions could now have unregulated risky investment bank operations that dealt in this highly risky instruments ... and which could cascade into taking down the whole institution. Indiscriminate pumping money into loans created a huge economic bubble that spread out into many areas of the economy. The collapse of the bubble affected all areas of the economy ... including businesses that had taken out standard commercial loans from depository institutions that had never played in the risky investment banking games (some of those businesses collapse and their traditional loans turn bad ... affecting institutions that never participated in any risk behavior).
The FED did play a major role in GLBA ... and therefor allowing banks to indirectly have risky behavior that could take them down. The FED also played other roles in other areas around the perimeter of the triple-A rated toxic CDOs (but didn't have any direct relation to the instruments).

that was somewhat red herring since problems with customers making source code changes was more than offset with having higher skilled customers that were capable of dealing with problems.
there was a fundamental problem with customers making source code changes and how fast customers could be migrated to newer products.
in the late 70s and early 80s ... there was period where there were incremental low-level (supervisor) hardware and operating system changes going on. in some corners this was viewed as countermeasures to clone processor competition. anything slowing down the customer from migrating to the latest hardware/software combination ... could result in the customer being more vulnerable to switching to clone processor from some other vendor (in part because the clone processor vendors would introduce machines at better price/performance ... but might have a year lag with including the latest hardware architecture tweak).
One of the most extreme version of this ... was leaking an early version
of my CSC/VM distribution to AT&T ... old email mentioning converting
lots of cp67 enhancements to vm370 for csc/vm distribution (otherwise
only within the company)
https://www.garlic.com/~lynn/2006v.html#email731212
https://www.garlic.com/~lynn/2006w.html#email750102
https://www.garlic.com/~lynn/2006w.html#email750430
this csc/vm distribution didn't have multiprocessor support and only ran with single processor configuration. at&t made additional enhancements (like virtual tape running over network ... i.e. application at one at&t csc/vm location could use local read/write channel program to a virtual tape drive ... which actually ran over a network link to real tape drive at a remote csc/vm system).
in any case, come the 80s ... this csc/vm distribution had propagated around AT&T ... but the next generation of IBM processors were 3081 ... which came only in multiprocessor flavor. clone processor vendor had single processor machine competitive with the aggregate 3081 multiprocessor thruput as well as price/performance competitive. the national marketing rep for at&t tracks me down ... looking for help migrating at&t from the ancient csc/vm system to a "modern" vm370 system with multiprocessor support.
some comments about (future system effort and) technology used in 3081
http://www.jfsowa.com/computer/memo125.htm
misc. past posts mentioning multiprocessor/smp support and/or
compare&swap support
https://www.garlic.com/~lynn/subtopic.html#smp
as i've mentioned before the initial morph of cp67 to vm370 involved a lot of simplification and dropping various things that were already shipping in cp67 product. the standard vm370 release didn't ship multiprocessor support until vm370 release 4 ... in the later part of the 70s.

i had done lots of work on os/360 and then cp67/cms as undergraduate in the 60s. the cp67 virtual machine culture had significant more focus on performance ... lots more attention paid in general to instrumentation, algorithms, etc. the separation of the functions into distinct entities simplified being able to focus on improving specific areas ... like resource management ... in traditional operating system lots of things were all jumbled together making it much more difficult to address/focus/solve.
lots of resources/attention were further focused on vm performance because there would be side-by-side comparisons running traditional operating system on the bare hardware (w/o the hypervisor) and under the hypervisor (difficult to run tso with and w/o the underlying os/360 operating system).
clean separation & partitioning simplified work on performance and resource management ... but also other stuff like security & integrity.

image of cms is still sitting around in the address space and CMS APIs can be invoked for some services ... but it is hardly a CMS virtual machine any longer. a lot of them used cms for basic scaffolding.
the multi-user spacewar game (done by the author of rexx) was similar,
cms was used for basic scaffolding to bring up the "server" ... which
then took over most of the machine.

a lot of the service virtual machines (or game servers as in the spacewar game) ... used paradigm where messages were "sent" to if (as if there was a normal person interacting with real terminal). cp67/vm370 "SPM" function was used to intercept the messages (intended for printing on real terminal) and handled under program control (specially for service virtual machines running disconnected w/o real terminal). This was used for deploying various "services" and/or automating various kinds of human "operator" functions.
old history email about SPM ... originally done on cp67 at Pisa science
center
https://www.garlic.com/~lynn/2006k.html#email851017
also mentioned in one of the features I included in csc/vm converting
from cp67 to vm370 (i started using vm370 pre-release slightly earlier

https://www.garlic.com/~lynn/2006w.html#email750102
https://www.garlic.com/~lynn/2006w.html#email750430
for whatever reason, rather than shipping SPM ... there was some NIH which started out inventing IUCV (a subset of SPM) and then adding SMSG (a different subset of SPM) ... to try and eventually provide all the features supported by the (internal) SPM.
I had done CMSBACK as backup/archive mechanism (ran around in service virtual machine off-shift checking for new/changed files to be written to tape). Independent of CMSBACK there was tape-management library that had directory of all tapes ... users set "messages" requested mounts ... which were intercepted, checked against the directory ... and then mount messages sent to a "real" operator for tape mounting.
Then a restore service virtual machine was added to CMSBACK ... users
could send query&restore messages to the CMSBACK restore service virtual
machine (get lists of all their files archived ... using wildcards in
filenames and/or date ranges for filtering and/or specify a specific
files or groups of files to be restored). The restore function had
access to the CMSBACK directory of all files and all backup/archive
tapes ... and correspondence between backup/archived files and
backup/archive tapes. After a couple internal releases, CMSBACK morphed
into the workstation datasave facility (shipped as product to
customers), which then morphed into ADSM, which subsequently morphed
into the current TSM. misc. old email mentioning CMSBACK

the scenario that the economists gave for "flat rate" tax was
1) special provisions eventually accumulate until the tax code is 60,000 pages and dealing with the complexity consumes something like 5-6 percent of GDP (aka any one special provision may be seen as positive contribution ... but the paradigm of having special provisions more than offsets the benefits of any special provisions ... it is sort of myopic/tactical vis-a-vis strategic ... or not seeing the "forest for the trees")
2) the tax code special provision paradigm creates a culture that results in major portion of the lobbying that goes on; being a major contributor to congress being considered the most corrupt institution on earth.
the social, cultural and economic costs of dealing with all the little nits are like the death of thousand cuts ... even if any specific special provision can be taken out of overall context and made to appear that it will be the savior of mankind (all wrapped up in motherhood and apple pie).

NAME
flock - Manage locks from shell scripts
SYNOPSIS
flock [-sxon] [-w timeout] lockfile [-c] command...
flock [-sxon] [-w timeout] lockdir [-c] command...
flock [-sxun] [-w timeout] fd
DESCRIPTION
This utility manages flock(2) locks from within shell scripts or the command line.
The first and second forms wraps the lock around the executing a command, in a man-
ner similar to su(1) or newgrp(1). It locks a specified file or directory, which
is created (assuming appropriate permissions), if it does not already exist.
The third form is convenient inside shell scripts, and is usually used the follow-
ing manner:
(
flock -s 200
# ... commands executed under lock ...
) 200>/var/lock/mylockfile
The mode used to open the file doesn't matter to flock; using > or >> allows the
lockfile to be created if it does not already exist, however, write permission is
required; using < requires that the file already exists but only read permission is
required.
By default, if the lock cannot be immediately acquired, flock waits until the lock
is available.
... snip ...
"hq.list" contains a list of 70 or so news webpage URLs from around the internet.
there is very tiny possibility of race condition ... that "sqlhq" asynchronous function doesn't set exclusive lock until after the first wgethq asynchronous function obtains the shared lock (however, realistically even if the asynchronous sqlhq function was stalled for unknown reasons, the ansynchronous wgethq functions do quite a bit of web operation before attempting to obtain the shared lock).
wgethq function eliminates previously seen news item URL (already in browser history file) from being sent to the browser for loading. The global serialization (in wgethq) is for the case where multiple different news sites might refer to the same news item URL ... so that it is only sent to the browser for loading once.

GML is derived from the initial of the last names of the people at the science center inventing GML. GML markup capability was added to cms script command ... which had started out as document formating using "dot" formating commands ... from CTSS runoff.
One of the first major corporate documents done (other than cp67 & cms documents from the science center) was the 370 architecture "redbook". The 370 architecture redbook could be formated as either the full document ... or just the "principles of operation" subset ... at the time was about half the size of the full "redbook" (redbook comes from the color of the red 3-ring binder that was used for the full manual).
there were old jokes about whole organizations that appeared to have formated documents as their only work product (i.e. specialized in being "script programmers" ... as opposed to strictly gml programmers)

including CAS in 370 was rebuffed because the POK favorite son operating

recent reference to book about the reverse-ipo/ipo transaction cycle.
https://www.garlic.com/~lynn/2010i.html#80 Favourite computer history books?
there is some analogy with the illegal stock portfolio transaction churning ... doing transactions purely for the purpose of the commission earned on the transaction (no intrinsic justification for the transactions other than the commissions on the transactions). the actual executives of the companies involved could be bought off with various kinds of bonuses and/or buyouts.
A lot of the mortgages from unregulated loan originators using toxic CDOs as source of money ... can also be framed as primary motivation for lots of the parties, was the commissions from the transactions (aka doing the transactions became an end-in-itself).
There was past reference to financial service industry tripled in size
(as percent of GDP) during the financial mess period. There was reported
to have been an aggregate of $27T in toxic CDOs done during the period.
Take the aggregate transaction commissions from writing the original
mortgate, real-estate transactions, secutizing the loans/mortgages and
selling the toxic CDOs ... an aggregate of 10% commission from all the
various transaction pieces comes to $2.7T ... more likely with all the
various transactions the aggregate commission comes closer to 20% or
$5.4T (not quite $1T/annum during the period).

Quite a few executives had another kind of financial fiddling going on, with bonuses tied to quarterly financial reports ... they would fiddle the reports to significantly inflate their bonuses. This was supposedly illegal before Sarbanes-Oxley & Enron ... and supposedly became even more illegal after Enron & Sarbanes-Oxley ... with Sarbanes-Oxley supposedly putting in lots more auditing procedures to prevent/catch such illegal activity.
Possibly because the GAO didn't believe that SEC was doing anything
... even after the passage of Sarbanes-Oxley and all the new audit
procedures, GAO started publishing reports of public company financial
reports (subject to SEC and Sarbanes-Oxley) that they considered
fraudulent and/or in error.

• Sarbanes-Oxley audits had no effect on fraudulent reporting • Sarbanes-Oxley audits encouraged public companies to increase fraudulent reporting • if it hadn't been for Sarbanes-Oxley audits, all public company would have been doing fraudulent financial filings

Waterloo SCRIPT is a rewritten and extended version of a processor
called NSCRIPT that had been converted to OS and TSO from CP-67/CMS
SCRIPT. The original NSCRIPT package is available from the SHARE Program
Library. Waterloo obtained NSCRIPT in late 1974 as a viable alternative
to extending ATS to meet local requirements. The local acceptance of
Waterloo SCRIPT has continued to provide the motivation for additional

takes that long today; they just bring the software to market much

the economists claim was that flat-rate tax (eliminating special provisions) would go a long way towards eliminating the massive corruption culture around congress (associated with most lobbying). More recently the massive corruption and lobbying associated with special tax code provisions has somewhat been overshadowed by the massive lobbying associated with financial & health reform bills. There was some claim recently that the financial industry got $1000 dollars in benefits for every dollar spent on congress (some claim that over the past ten yrs, they spent $5B on congress, implying the they saw something like $5T in benefits/ROI; which may have resulted in costing the country/economy ten times that).

part of what saw big upsurge in 43xx installations (in the mid-range ... as well as vax) ... was datacenters were becoming full. large commercial customers were ordering 43xx boxes multiple hundred at a time and placing them out in converted conference rooms and departmental supply rooms ... eliminating much of the upfront capital outlay for datacenter expansion. this bled off a lot of the datacenter growth in the late 70s and 80s.

more capacity with vendors moving to large higher capacity per sqft

in any case, new applications and/or business growth involving datacenter operations had significantly slowed &/or was declining by the 90s. some datacenters had gone from bursting at the seams to barely ten percent of raised floor occupied (combination of lack of growth and technology changes that packed much higher densities in much smaller footprint).
leakage of new applications & operations out into the distributed environment (mid-range machines and then workstations & large PCs) had started affecting mainframe datacenter growth by the early 80s ... which was sort of the start looking at other mechanisms to maintain annual revenue ... including the OCO-wars (transition from source to "object-code-only") of the early 80s.
customers had been making source moditifications to the core operating system. vendor might ship new hardware with new features that required the latest operating system. customer migration to newer operating systems were slowed by having source modifications ... which then delayed installation/sale of newer hardware.
even w/o source changes ... some of the mission critical datacenter operations have regression tests (part of strict/formalized "change control") that may take six months elapsed time ... and switch-over windows that only happen at 2-4 times a year.
LPARs somewhat helped with this ... basically a highly optimized virtual machine subset supported by the hardware. most mainframe operations now routinely run in LPAR-mode as normal operation with combinations of "production" LPARs and "test" LPARs running concurrently on the same machine.
more pervasive use of sysplex (i.e. loosely-coupled or cluster) also helps ... allowing rolling operating system switch-overs without having to take down everything at one time resulting in total service outage.
now ... at some time in the past, my wife had been con'ed into going to
POK to be in charge of loosely-coupled architecture ... where she
came up with Peer-Coupled Shared Data architecture ... some past
posts
https://www.garlic.com/~lynn/submain.html#shareddata
except for IMS hot-standby ... this saw very little uptake until sysplex ... which contributed to her not remaining long in the position. also there were ongoing battles with communication group trying to force her to use SNA for cluster coordination.
we then started ha/cmp (on rs/6000) before mainframe got around to
really doing sysplex ... misc. past ha/cmp posts
https://www.garlic.com/~lynn/subtopic.html#hacmp
of course, ha/cmp cluster scale-up perceived competition with mainframe
may have contributed to transfer of cluster scale-up (for numerical

... and some of the customer "operating system" (aka kernel) source code changes were NOT multiprocessor "safe" .... in the early 80s (about the time of the OCO-wars), next generation of more powerful IBM mainframes started out being multiprocessor-only (not even offering a single processor version). single-processor code locked the customer into single processor machines ... obstructing move to next generation of (multiprocessor only) mainframes. Aggrevating the situation was some clone processor vendors were offering more powerful single processor (non-multiprocessor) machines (as an alternative).
a slightly analogous situation is the recent transition with processor chip MHZ/mip rate reaching plateau and the move to multi-core chips (multiprocessor by any other name). Since the instruction speed had hit upper threshold ... higher thruput only comes from running multiple instruction threads in parallel (aka multiprocessing/multi-core).

the PC genre saw multiprocessor on server side in 90s (not multi-core ... but multiple chips sharing memory). Sequent claimed having done significant multiprocessor enhancements for NT ... for running on their intel-based multiprocessors (getting NT running on eight or more processors having significant higher thruput than NT running on just two processors ... which they claimed was significant issue when they started).
sever kernel then supported multiprocessors ... but applications needed multiprocessor/multithreaded operation to actually get more thruput out of a multiprocessor machine. DBMS servers that were optimized for multithreaded operation doing lots of different transactions concurrently fit that bill.
however, the desktop application environment tended to be single large monolithic applications that only saw higher thruput when running on faster processors. this is what desktop has experienced starting nearly decade ago. cellphones & PDAs have wanted touted multi-application support ... not so much needing multiple different application to be compute intensive concurrently ... but being able to instantaneously switch between applications avoiding stop & restart delays.

original 360 virtual machine implementation ran virtual machine in "problem mode" ... and all supervisor state instructions interrupted into the hypervisor kernel ... and were simulated (according to virtual machine "rules").
virtual machine assist started out as a special flag that basically implemented two modes for (some) supervisor state instructions ... "real machine" mode ... and virtual machine mode; virtual machine mode basically was what the hypervisor kernel would have done in simulation. over a period of a decade or so ... more & more supervisor state instructions were added to being done in virtual machine mode ... directly by hardware (w/o requiring interrupts into the hypervisor kernel and emulation by the software).
the original SIE implementation was on 3081 and a "heavyweight" instruction ... the 3081 having limited microcode storage ... so the initial execution of the SIE instruction (for entering virtual machine mode) was actually on a disk and had to be "paged" into microcode memory for execution.
Next generation 3090 ... had SIE instruction better integrated into the
native hardware and had significantly better performance. old email
discussing some differences between 3090 & 3081 (including SIE
implementation)

https://www.garlic.com/~lynn/2003j.html#42 Flash 10208
In the 3090 timeframe ... one of the mainframe clone vendors introduced "hypervisor" ... which was a subset of virtual machine capability implemented totally in the "hardware" ... eliminating the requirement for a separate virtual machine operating system (as long all that was needed was the hypervisor subset).
the response for the 3090 was "PR/SM" ... which was virtual machine subset ... implemented in the "hardware" ... and not requiring a separate virtual machine operating system (to partition the machine) as long as all that was needed was the subset function. PR/SM leveraged the SIE capabilty and originally SIE hardware function wasn't recursive ... aka a virtual machine operating system running in a virtual machine ... wouldn't have SIE capability being performed by the real hardware. Since PR/SM was using SIE instruction ... a virtual machine operating system running under PR/SM wouldn't have SIE available.
PR/SM evolved into LPARs (logical partitions) and running SIE under SIE support was added (since LPARs leveraged the internal SIE implementation ... it was necessary to add some recursive capability to allow a virtual machine operating system, running in an LPAR, to use SIE).

in the aftermath of the future system failure ... the favorite son operating system in POK managed to make the case that the virtual machine product needed to be killed and all the people transferred to POK to support the development of the "XA" version of that operating system (aka mid-70s).
