medicare part-d had 18 congressional members (& their senior staff) shepherding bill through and last minute add one sentence that prevents competitive bidding, they also prevent CBO from distributing analysis of the one sentence, until after vote passes. CBS 60mins shows identical drugs from VA (which allows competitive bidding) 1/3rd the price of medicare pard-d (w/o competitive bidding). after passes, all 18 have resigned and are on drug industry payroll. comptroller general characterises part-d a long-term $40T unfunded mandate that comes to swamp all other budget items. also seems to be part of the comptroller general's motivation for characterising nobody in congress capable of middle school arithmetic (first major legislation after congress allows fiscal responsibility act to expire in 2002 ... which required tax revenues match spending).
congress passing 401k puts large amounts of retirement funds into wallstreet hands ... the performance of 401k avg much worse than large retirement funds and the wallstreet fees/commissions for 401k is much larger than large retirement funds i.e. congressional 401k is enormous gift to wallstreet ... in much the same way that having S&L cut reserve requirements in half was enormous gift to wallstreet. The proposals from the last decade regarding privatising social security would have effectively put additional enormous additional funds into wallstreet for them to skim off (i.e. huge amounts of social security would have evaporated into various hands in much the same way that 401k funds evaporated last decade).
In much the same way the DEA followed the money trail involved in purchasing 737 jets used in drug smuggling back to too-big-to-fail doing the money laundering ... follow the money trail regarding efforts behind privatising social security (who benefits the most from the privatising of social security? and has enormous piles of money to heavily lobby washington).

CFTC is now allowing speculators to drive extreme volatility and wild price swings in commodities ... ala Grfitopia book and other news items.
Drop back a little, Born, head of CFTC, suggests that it needs to regulate CDS (as insurance instruments, there may be a couple trillion at risk ... however as gambling bets, there is now over $700T in CDS ... hundreds times more than any at risk insurance).
So drop back a little more, person is competing with Gerstner to be next head of AMEX ... and looses out, then leaves with his protoge Jamie Dimon. They go to Baltimore and take over a loan business, then over a few years make several acquisitions eventually culminating in Citibank ... which is in violation of Glass-Steagall. Greenspan gives Citi an exemption while the new CEO lobbies washington for repeal of Glass-Steagall (Sec. of treasury who happens to be former chairman of Goldman-Sachs, head of senate banking committee and others). Head of senate banking committee gets repeal included in GLBA. After GLBA passes, sec. of treasury resigns and joins Citi becoming co-chariman.
Various people oppose regulating CDS including Enron. Born is replaced as head of CFTC by wife of the head of senate banking committee, while her husband gets legislation included that prohits CFTC from regulating CDS. When that passes, his wife (head of CFTC) resigns and joins Enron board and member of the audit committee.
Enron and Worldcom explode and congress passes Sarbanes-Oxley
supposedly to prevent Enron/Worldcom from happening again; however it
requires SEC to do something. Apparently GAO doesn't believe SEC is
doing anything and does reports of public company fraudulent financial
filings ... even showing uptic after passage of SOX (question, does
SOX have 1) no effect on fraudulent filings, 2) encourages fraudulent
filings, 3) if it wasn't for SOX there would have been even larger
increase in fraudulent filings).

lots of activity predates most recent congress.

Repeal of Glass-Steagall opened the way for too-big-to-fail and risky behavior putting depository institutions at risk ... and apparently never ending assistance to such ill-considered behavior ... leading to moral hazard ... the expectation that there is no real risk in outrageous gambling ... if they win, they keep the beneifits, if they loose, the gov. steps in to save them. The current round is to make sure that there is no real limitations put on the risks that too-big-to-fail are able to take.

has some amount on executive compensation and bonuses have become misaligned with long-term corporate and public interest. there are some number of stories about executives becoming myopicly focused on managing the quarterly reports to exclusion of running the company. there is folklore that after the company went into the red in the early 90s ... that the several hundred top executives on the executive bonus plan focused solely on moving expenses from the following year to the year in the red (w/o regard to any consideration of actually running the company). The issue is that put the company slightly out of the red the following year and the way the bonuses were calculated as change from previous year, that year's executive bonus was more than twice as large as the largest bonus ever paid (i.e. the executives actually made more money than if the company hadn't gone into the red).
In the late 70s & early 80s I was blamed for online computer conferencing on the internal network (larger than arpanet/internet from just about the beginning until late '85 or early '86). There was some amount of discussion about the rise of MBAs and the need for common, generic, simplified measurement criteria ... allowing MBAs to run companies w/o actually needing to know what the company does ... was leading to the downfall of US business.

talks about FED keeping cost of money at nearly zero has been big driver for private equity industry. The firms borrow money to do reverse IPOs and buy up companies. They take enormous fees and comissions on the deal. Later they do IPO of the company ... difference from home speculators flipping houses, is rather than paying off the original loan (mortgage), the loan stays with the newly IPO'ed company (if rates rise later, the newly IPO'ed company may have severe problems servicing the debt). The rise of speculators and flipping houses the last decade was driven by the housing bubble (some parts of the country saw 20-30% inflation). Private equity firms can make enormous profits even if they flip a company at a loss (since the original loan doesn't have to be paid off and goes with the flipped company)

The funny thing in the Enterprise discussion, is that the discussion started out that mainframe software, services, & storage is generating more than six times the revenue of the mainframe itself ... i.e. max. Z196 goes for $28M and 25/4 multiplier makes total revenue $175M ... and then the discussion wanders off into how little the total cost of mainframe is (it is inconsistent to argue that total revenue from mainframes is enormous ... but apparently somebody besides customers are paying the bill if mainframe is so economical for customers).
The "Who Stole American Dream" goes into some detail of IBM effectively replacing large number of Americans with Indians ... going from 6k in 2003 to possibly 130k by 2010 ... and got so good at replacing American's with Indians that it set up a business unit to advise other companies on how to do it. As referenced upthread some number of comments in the book also by former IBM VP (and head of research).
also regarding ficon, zhpf, z10, z196, ec12, e5-2600, etc

https://www.garlic.com/~lynn/2012m.html#4
Lawrence Livermore National lab started work on fibre channel
standard in 1988. I've been involved with national lab on&off since 1979
when trying to sell them large clusters of 4341s. I was active in
fibre channel included when POK channel engineers become involved in
the 90s ... working on layering FICON on top that significantly cut
throughput (for the FICON layer compared to base fibre channel). old
email referencing 4300s
https://www.garlic.com/~lynn/lhwemail.html#4341
fibre channel has always been able to do concurrent in both directions so latest 16gbit fibre channel theoretically does 32gbit aggregate or equivalent of 4M 4kbytes/sec, 2m concurrent in both direction. IBM documents has z196 doing 2m 4kbytes peak using 104 FICON channels to 14 storage subsystems. emulex reference is their latest fibre channel for e5-2600 is capable of over 1m IOPS (aka single channel). Also says that z196 peaks at 2.2m SSCH/sec with all 14 SAPs running at 100% busy ... but recommends keeping SAPs at no more than 70% busy ... or 1.5m SSCH/sec. IBM zHPF document discussion is that it operates the same for z196 and ec12.
I did HA/CMP and was doing cluster scale-up in conjunction with fibre
channel standard (for both numerical intensive/scientific including
with numerous national labs as well as commercial) ... old post

and old email regarding cluster scale-up

within hrs of last email mentioned above (end of Jan92), cluster
scale-up was transferred and we were told we couldn't work on anything

as an aside, in the 80s was working with NSF on what would become the
NSFNET backbone (tcp/ip is the technology basis for modern internet,
NSFNET backbone was the operational basis for the modern internet and
CIX was the business basis for the modern internet). some old email
https://www.garlic.com/~lynn/lhwemail.html#nsfnet
when the NSFNET backbone rfp was released, internal politics prevented us from bidding (some of the same executives later involved in transferring cluster scale-up were also involved in preventing us from bidding on NSFNET backbone). The director of NSF tried to help by writing the company a letter 3Apr1986, NSF Director to IBM Chief Scientist and IBM Senior VP and director of Research, copying IBM CEO), but that just made the internal politics worse

Has DOD testifying before congress that there wasn't any chemical/biological weapons during desert storm ... when they knew there were. The apparent explanation was that they didn't want it known that they knowingly sent in US military without adequate protection (and tried to have VA stonewall admitting the soldiers were suffering effects from chemical/biological weapons). Then a decade later, when Iraq no longer had WMDs, they use the excuse that they had WMDs, to go in again.
loc7297-7301:
Retirement had been kind to Norman Schwarzkopf. Scattered post-war
revelations--Patriot missiles missing every SCUD fired by Iraq, Saddam
still entrenched in Baghdad--had failed to shake the public's
favorable perception of "Stormin' Norman" as triumphant war hero. The
former general enjoyed lucrative speaking engagements around the
country and he served as a paid consultant to NBC News. Six years
after America's "victory" in Desert Storm, the only nettlesome issue
confronting Schwarzkopf was "a few" sick soldiers with unexplained
illnesses.

But in Dick Cheney the Pentagon had a rare SecDef. Cheney had enough
one-on-one sessions with Boyd to give him the knowledge and
self-confidence to second-guess even a headstrong four-star general
such as Norman Schwarzkopf. Simply put, Cheney knew more about
strategy than did his generals.

Schwarzkopf and several generals have since spent much of their time
blaming each other, but it was the slavish adherence to an outmoded
attrition-warfare doctrine that allowed the Iraqis to
escape. Boyd's earlier predictions about synchronization in
the Army were proven true.

More than $27 trillion of these securities have been sold since 2001,

Banks' Hidden Junk Menaces $1 Trillion Purge
Bank's Hidden Junk Menaces $1 Trillion Purge
http://www.bloomberg.com/apps/news?pid=newsarchive&sid=akv_p6LBNIdw&refer=home
from above:
At the end of 2008, for example, off-balance-sheet assets at just the
four biggest U.S. banks -- Bank of America Corp., Citigroup Inc.,
JPMorgan Chase & Co. and Wells Fargo & Co. -- were about $5.2
trillion, according to their 2008 annual filings.
... snip ...
TARP funds were originally appropriated for the purchase of these toxic assets ... but with only $700B appropriated, it wouldn't have even come close to making a dent in the problem (at least not if purchased at face value). Note the fall of 2008, toxic assets were going for 22cents on the dollar ... the $700B would have covered a little over half of the $5.2T for just the four largest too-big-to-fail at 22cents on the dollar ... but that would require facing that they were failed institutions ... and still wouldn't have been able to clear the problem. Note that a lot of the fed money (Bloomberg spent two years in court with federal reserve getting them to release what they were doing) was purchasing toxic assets at between 98cents and 100cents on the dollar.
Note a big motivation for wallstreet pushing these instruments (and looking the other way as corners were cut) was the commissions&fees from the sales of the instruments ... i.e. they didn't actually care what was being sold ... just so long as they could churn out the transaction sales. Towards the end, there were even stories of custodians of the off-balance toxic asset warehouses effectively exchanging equal amounts of assets in sales to each other (as way of keeping the commissions&fees coming in).
note that securitized mortgages had been used during S&L crisis to obfuscate fraudulent mortgages ... however, w/o the triple-A ratings there was not much of market. Being able to pay the rating agencies for triple-A ratings (when both the rating agencies and sellers knew they weren't worth triple-A ... from congressional hearing testimony into the role that the rating agencies playing in the financial mess). The triple-A ratings enormously increase the market for the toxic assets ... especially large institutional funds restricted to only dealing in "safe" investments ... like the large retirement funds.
Note triple-A rating trumps documentation. Late last century we were asked to look at improving the integrity of supporting documentation in securitized mortgages as countermeasure to the use of securitized mortgages for fraudulent mortgages (done during the S&L crisis). However, with the (paid-for) triple-A ratings trumping documentation, loan originators could do no-documentation mortgages ... and with no-documentation there is no longer an issue regarding documentation integrity.
This also comes up with MERS and subsequent robo-signing to generate fraudulent documents after the fact
Note that 10% skim on the $27T transactions would be $2.7T ... the
increase in wallstreet wealth during the bubble would indicate a take
more like between 15% and 20% on the $27T in transactions ... of
course some of that may have come from other manipulations
... including creating toxic CDOs that they knew would fail, paying
for the triple-A ratings ... and then making CDS bets that they would
fail. There have been claims that wallstreet as percent of GDP,
tripled during the bubble ... indicating that their increased take
during the bubble was something over $5T.

LLNL had some serial technology and around 1988 they started effort to

note that long-time loyal customer of mainframes are big financial institutions that frequently have large number of maximum configured mainframes in single datacenters (frequently sized to complete work in overnight batch window). they could be considered driving factor behind increasing max. number of processors in single configuration ... going from 64 processors with z10 to 80 processors with z196 to 101 processors for ec12.
I've pontificated periodically that many of these institutions spent billions in the 90s on failed re-engineering mainframe overnight batch applications for straight-through processing on large number of parallel killer micors
old posts about doing working on performance optimization for major
mainframe customer a little over a decade ago. They had 40+ maxed out
mainframes (of the period, max age of their mainframes was 18m) at
around $30M (well over $1B). The size/number of mainframes were
dedicated by large 500k statement cobol application that ran in
overnight batch window and needed to complete in the overnight
window (some other financial institutions considered this a "small"
operation)

from above:
zHPF improves upon FICON by providing a Transport Control Word (TCW)
that facilitates the processing of an I/O request by the channel and the
control unit. The TCW has a capability that enables multiple channel
commands to be sent to the control unit as a single entity instead of
being sent as separate commands as in FICON CCW. In addition, the
channel is no longer expected to process and keep track of each
individual CCW. Instead, the channel forwards a chain of commands to the
control unit to execute. Reduction in this overhead cost increases the
maximum I/O rate possible on the channel and improves the utilization of
the various sub-components along the path traversed by the I/O request.
... snip ...
original os/360 paradigm was channel programs were built by application (or libraries) and passed to the system with EXCP for execution. the mainframe channel program paradigm uses "real" addresses for execution.
the original virtual machine cp67 in the 60s ... (for SIO simulation) had to scan virtual machine channel programs, making copy of the channel program, that replaced the virtual machine virtual addresses with "real" addresses. when initial VS2 was being built ... it started off with SVS (single virtual storage) ... effectively laying out an MVT in a 16mbyte virtual address space ... minimum changes hacked into the side of MVT to setup the virtual address space table, handle page fault, do paging operations. Possibly the biggest effort for initial mapping of OS/360 to virtual memory was hacking CP67's "CCWTRANS" into EXCP processing to handle scanning of the passed channel program (that had virtual addresses) to create a copy that had real addresses.
EXCPVR call (aka virtual=real) was added to bypass scanning & creating
copy ... that invoking application had done a bunch of special stuff to
fix virtual pages in real storage and create channel programs with the
real addresses ... rather than virtual addresses. reference to use of

CFTC is now allowing speculators to drive volatility and wild irrational price swings in commodities ... ala Griftopia book and other news items
Drop back a little, Born, head of CFTC, suggests that it needs to regulate CDS (as insurance instruments, there may be a couple trillion at risk ... however as gambling bets, there is now over $700T in CDS ... hundreds times more than any at risk insurance).
So drop back a little more, person is competing with Gerstner to be next head of AMEX ... and looses out, then leaves with his protoge Jamie Dimon. They go to Baltimore and take over a loan business, then over a few years make several acquisitions eventually culminating in Citibank ... which is in violation of Glass-Steagall. Greenspan gives Citi an exemption while the new CEO lobbies washington for repeal of Glass-Steagall (Sec. of treasury who happens to be former chairman of Goldman-Sachs, head of senate banking committee and others). Head of senate banking committee gets repeal included in GLBA. After GLBA passes, sec. of treasury resigns and joins Citi becoming co-chariman.
Various people oppose regulating CDS including Enron. Born is replaced as head of CFTC by wife of the head of senate banking committee, while her husband gets legislation included that prohits CFTC from regulating CDS. When that passes, his wife (head of CFTC) resigns and joins Enron board and member of the audit committee.
Enron and Worldcom explode and congress passes Sarbanes-Oxley supposedly
to prevent Enron/Worldcom from happening again; however it requires SEC
to do something. Apparently GAO doesn't believe SEC is doing anything
and does reports of public company fraudulent financial filings ... even
showing uptic after passage of SOX (question, does SOX have 1) no effect
on fraudulent filings, 2) encourages fraudulent filings, 3) if it wasn't
for SOX there would have been even larger increase in fraudulent
filings).

MVS inherited a environment that was strongly pointer passing API ... theoretically requiring the services to occupy the same address space as the applications (from real-storage days). The initial transition to virtual memory was VS2/SVS which basically laid it the real-storage "MVT" in a single 16mbyte virtual address space ... with abbreviated support that created the virtual address table and handle page faults (not a whole lot different from running MVT in a 16mbyte virtual machine under cp67). The slight caveat is I/O programs are built in application space with "real addresses" and passed to supervisor for execution via EXCP. Initially SVS borrowed CCWTRANS from CP67 that was used to scan a virtual channel program, creating a copy, replacing the virtual addresses with real addresses (as addition to EXCP processing).
The next step transition from VS2/SVS to VS2/MVS (single virtual stroage to multiple virtual storage), each application got its own 16mbyte virtual address space. However, because of the pointer passing API requirements ... there was an image of the MVS kernel mapped into 8mbyte of every application 16mbyte virtual address space. There was also some number of system services that resided outside the kernel ... that were in their own separate virtual address space ... that continued to support pointer passing API from applications. To support pointer passing API between applications and services between different virtual address space, the COMMON SEGMENT (initially 1mbyte) image was created that occupied every virtual address space (where application and services could allocate information and pass pointers back&forth).
In parallel with this, work began on "370-xa" extensions, 31bit virtual addresssing ... but also multiple virtual address support (access registers) ... leading to description about home, primary, secondary, etc "address spaces". Initially, this would involve application making kernel call for a service ... the kernel would load the service virtual address space and put the application virtual address space as secondary. Eventually lots of services code would be modified to reference pointer data in secondary address space (rather than common segment primary address space).
Before 370-xa ships, larger 370 systems were running into significant common segment constraints ... increasing number of system services in private address space and larger number of concurrent applications resulted with installations having to define 5-6mbyte common segments (leaving only 2-3mbytes of every 16mbyte address space for application) ... and under threat that it might need to increase to 7-8mbyte common segment (possibility that nothing is left for application).
The person that later goes on to be major force behind Itanium, retrofits part of 370-xa to high-end "3033" 370 as "dual-address-space" mode ... allowing some MVS services to get an early start on accessing application information as secondary address space rather than CSA (originally "common segment area " ... later "common system area")
part of full 370-xa extensions was also program call&return. Kernel would setup table for program call ... that had virtual address space pointer for each services. Eventually application could do a "program call" which would perform the switch to the specific services address space ... moving calling application address space to secondary (effectively almost library call/return ... except there is virtual address space fiddling goes on at the same time).
Parts of MVS is still stuck with 24bit mode ... in this case supporting
"Format 0 CCWs" ... which is 24bit address fields. ... furthermore
channel command words ... are (24bit) "real" addresses

some cross-over from this discussion here:

One of my co-workers had called up Chuck Spinney after seeing this
article ... gone behind paywall, but lives (mostly) free at wayback
machine (except pg8)

also
https://content.time.com/time/magazine/article/0,9171,953733,00.html
Spinney suggested he talk to Boyd (Boyd would tell story that SECDEF blamed Boyd for the article and tried to have him transferred to Alaska and banned from the Pentagon for life). The co-worker then con'ed me into sponsoring Boyd's briefings ... which I then did a number of times.

what i found was a large application feature/function that multiple regression analysis showed was accounting for 21% of total application usage ... which nobody could explain or account for. The function was complex operation which invoked a large number of different application features ... each one of the individual application features had been extensively optimized. The eventual explanation was that the function was repeatedly executed three times for each operation ... when it should have only been invoked once.

Army budget had been cut below the tank discount threshold ... so it needed Marines to take enough tanks to get aggregate numbers for the per tank discount.

That explains why Army got M1s ... doesn't change that Marines find themselves with enough M1s so the total number (Army+Marines) come up to the number needed for the volume discount. Also set up some part of Marines on trajectory that is little different than adjunct to Army. One issue has been Marines justify unique roles that keeps them from eliminated as different organization.
There are claims that some amount of European infrastructure rebuild last century was specifically to handle M1 loads. That is tempting to drift into subject about how similar infrastructure in US was neglected during the period ... "Confidence Men" has a civil engineering professor talking to Volcker about last several decades civil engineering programs at univ. being eliminated (lack of building programs, lack of jobs for civil engineering graduates, no jobs means drop off in students) ... and Volcker responds: "Well, I said, 'The trouble with the United States recently is we spent several decades not producing many civil engineers and producing a huge number of financial engineers. And the result is s*tty bridges and a s*tty financial system!". Some number of recent US rebuild projects have gone to companies from foreign countries that are still producing civil engineering graduates.

Amdahl gave talk in early 70s in large mit auditorium about starting his new clone processor company. one of the questions was what argument did he use to get funding. his comment was that customers had already invested enormous amounts in 360/370 software applications ... that even if ibm were to completely walk away from 360/370 (might be considered veiled reference to future system) ... that install base would be sufficient to keep him in business until the end of the century.

long-winded email from long ago and far away (repeated from discussion
with 3090 processor engineers):
Date: Jun 15 11:27:41 1989
From: wheeler
To: distribution
Subject: 3090 vector
My understanding of 3090 vector was that it was primarily a marketing
ploy. With a little additional smarts and 7-stage pipeline ... 3090+
would execute instructions at memory bandwidth speed. The advantage
(over vector) is that both numerical instensive (done via vector or
scalar) would proceed at memory bandwidth spped AND all other scalar
would also operate at memory bandwidth rates also. I believe that
Hitachi has such a machine ... i.e. vectorization has little
additional performance improvement over scalar since the scalar
pipelining was operating memory bus at peak thruput.
The advantage (in the past) that vectorization has had over scalar is
that the pipelining algorithms haven't been sophisticated enough. The
seven stage pipeline would require less (additional) circuits than
vector unit and still operate the hardware at peak efficiency. The
problem is trying to design hardware systems that maximize the
utilization of all the system components ... as well as total system
thruput.
At one time there was work going on to build a dual i-stream version
of the 370/195. The problem was that the 195 pipeline would drain when
a branch instruction was encountered. The net result was that the
hardware very seldom would operate at peak thruput. Adding a second
i-stream to the hardware ... but continuing to use the same amount of
execution and pipeline hardware (just taging each instruction as to
its i-stream) ... effectively doubled the number of available
instructions in the pipeline (probability of pipeline totally draining
because both i-streams were at branches was low). The 3090+ 7-stage
would support looking down both paths of a banch ... in an attempt to
keep the pipeline full.
In some sense, vectorization is its own form of pipelining in order to
optimize the total utilization of all the system components (memory,
memory bus, i/o, cpu, i-unit, caches, e-units, floating point, etc).
Sophisticated scalar pipelining is also capable of similar results
with the added advantage of being applicable to total mix of
instructions being executed.
370 MP
However, both approaches reach thruput bottlenecks at single bus to
memory. Parallel execution has the advantage that more of the hardware
components are duplicated ... and therefor the peak possible sustained
thruput have fewer single points of contention. Although this isn't
alwas the case, most of the ibm mainframe MP implementations bog down
because of cache and software syncrhonization problems ... which is
somewhat an artifact of the software having minimally evolved from an
UP design point. Large parts of the operating system are still very
much UP design point ... adapted to MP environment by defining
critical sections that are bracketed by TS instructions. Basic UP
design-point system with little thot to data scoping will rely heavily
on single view of all data across all processors (i.e. cache
syncrhonization heavily utilized) as well as numerous serialized
critical code sections with TS looping.
There was a lot of work done for atomic CS with the design point of
(at least in the software) eliminating critical sections and TS
bracketing. However over the last 15 years this has had minimal
propagation into major portions of the system. Other contributing
factors have been in several situations fully parallel system code has
been maintenanced (over a period of years) into critical section code
with TS bracketing (a major problem over a 15-20 year development
period is making sure that all people that might touch a piece of code
are as skilled and talented as the people who originally wrote it).
Given a mix of programmers, there are some that barely understand
concurrent multiprogramming (on a UP) and their solution to
concurrency problems is to disable critical sections ... that
background translated into MP environment results in bracketing with
TS loops.
In any case, a major design opportunity ... starting at the lowest
kernel level ... is adequate attention to scoping/partitioning data,
control blocks, etc with the objective to minimize critical sections
with TS loop bracketing. This would then translates into less hardware
degradation because of cache syncrhonization overhead ... as well as
less software degradation because of TS looping on bracketing critical
code sections.
... snip ... top of post, old email index
as i've mentioned before, CS had been invented by Charlie at science
center while doing fine-grain multiprocessor locking work on cp67.
the initial attempt to get it included in 370 was rebuffed, the
favorite son operating system people in POK saying TS was more than
sufficient. The 370 architecture "owners" explained that to get CS
included in 370, uses for the instruction would be needed other than
the kernel multiprocessor operation. thus was born the uses for
multi-threaded (multiprogramming) applications (regardless of whether
or not running in multiprocessor environment) ... the examples still
appear in the mainframe principles of operation. misc. past posts

Part of s/38 was single-level store from FS ... something that was at least some part from tss/360 (and in its simplified s/38 form was common disk allocation pool across all drives that would never scale).

I thought the 370/168 was a 370/165 plus virtual memory (paging) and
that the /165 was the successor to the 360/65.
370/155 & 370/165 were shipped w/o virtual memory. when virtual memory
was announced there was hardware upgrade to add virtual memory
(370/155-II and 370/165-II) ... which was extra cost for customers with
machines already in the field.
there was also problems with the development of the virtual memory hardware for 165, schedule was slipping and eventually decision was made to drop several features from 370 virtual memory in order to buy six month schedule. This required that all the other processors that already had the full 370 virtual memory implementation to also drop the full features ... and any already developed "virtual memory" software using the dropped features had to be redone.
this had a big hit to vm370/cms since cms had been structured to have shared segments (across all address spaces) that used "segment protect" ... one of the features dropped as part of the 165 schedule rework for virtual memory retrofit.
mvt had protected its kernel storage with 360 "storage protect" keys. in the transission from mvt to virtual memory OS/VS2 SVS ... it effectively laid out MVT in a single 16mbyte virtual address space ... continuing to rely on 360 "storage protect" keys. In the transition from SVS to MVS ... where each application got is own 16mbyte address space ... segment sharing was used to map the MVS kernel into 8mbytes of every application address space ... but the kernel continued to use 360 "storage protect" keys (didn't have the vm370/cms problem where virtual address space could do nearly anything it wanted to within its own address space ... and therefor "shared segments" needed the original 370 virtual memory segment protection feature ... which was among the features dropped in order for 165 to meet schedule)
155 & 165 both had processor caches with 2mic main memory. Big change from 165 to 168 was from 2mic memory to 320nsec main memory (as well as virtual memory came standard). The machines were horizontal microcode and the 3033 engineers that I did some work with ... mentioned in going from 165 to 168 they reduced the avg. machine cycle time per 370 instruction from avg of 2.1 machine cycles to 1.6 machine cycles (by reworking the horizontal microcode implementing 370). There was then a doubling of cache size in 168-1 to 168-3 from 16kbytes to 32kbytes ... the 168-3 was basis used for 3033.
There were a couple of us that wanted to do 16-way 370 multiprocessor and had gotton some of the processor engineers working on 3033 to work on the 16-way effort in their spare time (a lot more interesting than what they were doing on 3033). Everything was going along fine, many in the company thought it was great ... until somebody happen to mention to the head of POK (high-end 370 mainframe land), that it might be decades before the POK favorite-son operating system (MVS) would have 16-way SMP support. At that time, the head of POK invited some of us never to visit the POK location again ... and told the 3033 engineers to solely focus on 3033 and stop being distracted.
the processor engineers working on 3033 were concurrent with group
working on 3081 ... some more here:
http://www.jfsowa.com/computer/memo125.htm
when the 3033 was out the door, the 3033 engineers started work on 3090.

there were 3031, 3032, and 3033 ... plus an external channel director box (six i/o channels). the 158-3 had "integrated" channels ... the same microcode engine used for 370 execution was also shared doing channel i/o functions. for the channel director box, they took a 158-3 w/o the 370 microcode, just the integrated channel microcode. A 3031 was a 158-3 engine with new covers and the integrated channel microcode removed with a 2nd 158-3 engine (as channel director) with just the channel microcode. A 3032 was 168-3 with new covers and reconfigured to use (158-3 integrated channel) channel director. The 3033 was 168-3 logic remapped to faster chips ... and one or more (158-3 integrated channel) channel directors.

this old post with old hardware measures shows that the newer

hardware tended to be 1/3rd sec to 1/2sec.
https://www.garlic.com/~lynn/2001m.html#19 3270 protocol
one of the main east coast internal datacenters had published report that included claims that they had the best vm370 online service in the company with quarter second avg trivial system response. I complained pointing out that I ran several (similar, hardware configuration & workload) systems that had .11sec 90th percentile trivial system response (achieving .2 second human response with channel attached 3272/3277 terminals). response I got back was that particular datacenter could claim anything they wanted to in their reports.
from ibm jargon (by author of rexx):
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.

and from
http://www.army-technology.com/projects/abrams/
The first M1 Abrams battle tanks were delivered to the US Army in 1980. In all 3,273 M1 tanks were produced for the US Army, 4,796 M1A1 tanks were built for the US Army, 221 for the US Marines and 880 co-produced with Egypt.
and from
http://www.nationaldefensemagazine.org/archive/2002/September/Pages/Army_Marine6671.aspx
The Corps has yet to decide how many of the new vehicles it will need
to replace the existing fleet of 403 tanks. MEFFV is not designed as a
one-for-one replacement program, Beal said.
As to whether the MEFFV will be tracked or wheeled, Beal said that
still is up in the air. "We would like, for the 30-ton assault
variant, to have 8x8 tracks-over-wheels. That gives us the flexibility
to operate in a tracked or wheeled mode," he said. "For the lighter
ariants, we'll use wheels."

An unnamed Bush administration official actually went so far as to
claim that the lack of Iraqi propaganda attacks on Saudi Arabia argued
against an Iraqi invasion of the kingdom. Focusing solely on Iraqi
statements was precisely the mistake made prior to the invasion of
Kuwait. Saddam's public declaration that he desired a "dialogue" with
Kuwait had been nothing more than a smoke screen behind which he'd hid
his military preparations--just as Hitler had over 50 years before
when he annexed Austria. I had a sick feeling that history was about

another human factors study related to productivity was that human attention started to wander when response wasn't within their threshold ... and then when the response came ... the time it took to refocus was about the same duration as attention spent wandering ... i.e. "loss of productivity" was twice the elapsed time delay between the expected response and the actual response.

CCWTRANS was scan the passed channel program (in CP67 case, from the virtual machine virtual address space), duplicating each CCW, fixing the virtual pages involved in data transfers in real storage (so they wouldn't be selected for page replacement before the i/o had completed) and replacing the virtual addresses with real addresses (along with UNTRANS after the i/o completed, unfix the virtual pages involved in the i/o transfers and release the storage for the duplicate channel program). Note in CP67 case supporting "MINIDISKS" ... it also required duplicating the disk arm seek location and adjusting the value to reflect the location on real disks.
Transition from OS/VS2 SVS to MVS required a lot more work. It required building a unique virtual address space for every application ... and laying out the MVT kernel as an 8mbyte image that appeared in every application virtual address space. There was also an issue with the OS/360 extensive pointer-passing API paradigm. MVT "subsystems" that were outside the kernel now how their own virtual address space ... but were still required to access (fetch/store data) at the passed API location in the application virtual address space.

From: Anne & Lynn Wheeler <lynn@garlic.com> Date: 14 Oct 2012 Subject: Under what circumstances would it be a mistake to migrate applications/workload off the mainframe? Blog: Enterprise Systemsre:
There are large number of major failed "re-engineering" efforts ... some being retargeted to non-mainframe ... but also some not re-hosted ... just remaining on mainframe platform. Lots of re-engineering failures ... aren't because of targeted to a different platform ... but because of the nature of re-engineering ... independent of platform
There may be mis-impression about current generation of x86 processors. For decades RISC chips have had significant performance advantage over x86 ... i.e. for decades RISC chips have had out-of-ordered execution, branch prediction, speculative execution, etc. The past few x86 generations have actually been risc cores with hardware layer that translates x86 instructions into risc micro-ops (starting to significantly eliminate the throughput difference between x86 and risc).
One of the latest generation of x86 is e5-2600 blade that is two-chip 8-core/chip for 16-core (or processor) multiprocessor with a rating of 527BIPS or 33BIPS/processor and IBM base price of $1815/blade or $3.44/BIPS)
By comparison maxed out configurations for z10, z196, and ec12 are 30BIPS (64 processors), 50BIPS (80 processors), 75BIPS (101 processors) or 469MIPS/processor, 625MIPS/processor, and 743MIPS/processor. Half of the z10->z196 per processor improvement is adopting risc "out-of-order" execution ... and much of the z196->ec12 per processor is further improvements in the use of risc "out-of-order" execution. However, a single e5-2600 blade at 527BIPS (with 16 processors) is still the processing equivalent of seven fully configured ec12 machines (i.e. 527BIPS/75BIPS).
IBM has list price of $28M for fully configured z196 (at 50BIPS) and elsewhere in this group there is statement that IBM makes 4% of its revenue from selling mainframes but 25% when services, software, and storage are included. That results in IBM earning total of 6.25 dollars for every dollar in mainframe sales (i.e. 25/4). That translates into $175M cost for a $28M max. configured z196 or $3.5M/BIPS ($175M/50BIPS). That compares to ibm's base list price of $1815 e5-2600 ... which at 527BIPS works out to $3.44/BIPS (or one millionth the price/BIPS of z196).
this is recent discussion in ibm-main mailing list of FICON i/o
capacity.
https://www.garlic.com/~lynn/2012m.html#4
FICON was layered ontop (in mid-90s) of the fibre-channel standard ... that significantly cut the underlying fibre-channel throughput (originally from 88-92 time-frame). The above references IBM documents with z196 benchmark at peak 2m I/O ops/sec (IOPS) with 104 FICON channels, 14 storage subsystems and 14 system assist processors. It mentions that 14 SAPs are capable of 2.2M SSCH/sec at 100% processor busy, however it recommends normal operation that SAPs be kept at 70% or less processor busy (1.5M SSCH/sec)
By comparison, it lists a recent emulex announcement of single fiber-channel for e5-2600 capable of over one million IOPS. A single $1815 e5-2600 blade has seven times the processor throughput of a max ec12 and nearly the same I/O thruput of a max. configured z196 that uses 104 FICON channels ... but only using a single fibre-channel standard (i.e. the FICON layer enormously restricts the thruput of the underlying fibre-channel standard)
Other IBM references show that the recent zHPF and TCW enhancements to FICON ... partially restores the throughput of the underlying fibre-channel standard to FICON operations. Part of the original fibre-channel standard ... going back to 1988 ... was downloading complete I/O program in one transfer. The initial FICON layer for fibre-channel dropped back to only downloading a single CCW at a time. The recent zHPF enhancements for FICON introduces TCW that will package multiple CCWs for a single transfer.
A few racks of e5-2600 blades has the potential of having more I/O capacity and processing throughput than the total aggregate of all mainframes in the world today.
There is estimate that there are total of 10,000 mainframes in the world today. Even if every one of those turned out to be a max configured 50BIP z196 ... that only works out to be an aggregate of 500TIPS or less than 1000 e5-2600 blades. More realistic most of those systems are older ... so more like aggregate of 5TIPS or 100 e5-2600

the dhrystone mips benchmark isn't direct calculation of instructions per second ... it is "dhrystone" mips ... the number of interations of the benchmark compared to the number of interations for a 1mip vax machine (vax instructions being comparable to 360/370) ... a machine that 4341 competed favorably against (and assumed to be roughly equivalent types of instruction & mip rate as vax).
machines might actually have radically different actual number of instructions to execute a dhrystone iteration ... but would be normalized to the same base ... the number of interations done per second

In 1979, I did some benchmarking for the Endicott performance group for national lab on 4341 ... that was looking at getting computational farm of 70 4341s. The issue was that I was allowed to play disk engineer in bldgs. 14&15 ... in part because I provided them lots of software that significantly increased their productivity ... which also gave me lots of access&leeway in using their machines. They tended to get the 2nd or 3rd engineering model (370s both from endicott and POK) ... to start doing disk i/o testing. As a result I had much better access to 4341 than the Endicott performance group.

In any case while SSCH was being designed/architecture, I was interested in how quickly I could do I/O redrive in straight 370 (w/o offload dedicated processor).
I was rewriting the I/O supervisor for the disk engineering and product test labs (bldg. 14&15) ... to allow them to do concurrent development testing in operating system environment. They had previously tried MVS ... but found in had 15min MTBF (requiring manual re-ipl) with single device testing. As a result they dropped back to doing dedicated stand-alone testing, prescheduled, 7x24 around the clock. My objective with I/O supervisor rewrite was make it bullet proof and never fail, allowing concurrent, on-demand, anytime testing ... significantly improving development productivity.
While, I was doing the rewrite, I figured I could try and make the interrupt/redrive pathlength as short as possible ... w/o impacting integrity of system and I/O operation. I never made it to quite what a separate dedicated external processor ... but significantly improvement over the operating systems of the time ... especially compared to the enormous elapsed time it took MVS (indicating the significant performance improvement justifying SSCH was primarily based on the comparison to the enormous poor throughput in the MVS implementation).

Note that running at 100% utilization and still providing instantaneous on-demand response takes a lot of design, work and care&feeding. The economics trade-off of providing that level of sophistication is quite different if the system cost is running $3.44/BIPS versus $3.5M/BIPS (a factor of million difference in system cost). It is lot easier to justify the sophisticated support, care&feeding when the system cost is million times more expensive.
There are numerous cloud mega-datacenters around the world ... everyone with more processing power than the aggregate of all mainframes in the world today. There have been several stories about organizations carving out an "on-demand" supercomputer from a cloud operation ... that the "supercomputer" is provisioned, spun-up, run for a couple hrs and then shutdown ... all without actually talking to anybody at the cloud operations ... just using the standard online facilities. And several of these "on-demand" supercomputers (available processing power subset of a cloud operation) represent more processing power than the aggregate of the processing power of all mainframes in the world today. Imagine an organization having large number of mainframes ... several times that of all mainframes in the world today .. all sitting idle ... so that they would be available for instantaneous, on-demand use. One of the reasons that these mega-datacenters are like aircraft hangers ... is because each one contain multiple times the processing of the aggregate of all mainframes in the world today.
There was recent article that the number of datacenters (in the world) are decreasing but the avg. size is increasing ... in part because of the growth of the cloud megadatcenters ... with organizations moving some amount of their processing to the cloud.
In the 70s&80s ... my custom vm370 kernels ran on large number of internal datacenters and were expected to run at 100% utilization with near instantaneous interactive response ... when the equivalent MVS systems were recommended to run at 60-70% utilization in order to provide "decent" TSO response (where the "decent" TSO response was considered horrible and unacceptable by vm370/cms users). This is somewhat analogous to the recent published benchmarks of z196 I/O capacity and recommendation that SAPs are kept to 70% cpu utilization for SSCH processing (i..e. 1.5M SSCH/sec instead of peak possible 2.2M SSCH/sec).
for other topic drift ... recent discussion in a.f.c. regarding
original design for SSCH and justification for move from SIO to SSCH
in 370/xa:
https://www.garlic.com/~lynn/2012n.html#46 .
https://www.garlic.com/~lynn/2012n.html#47
note as mentioned above, max configured z196 was 2M IOPS using 104 FICONs, 14 storage subsystems (and 14 SAPs) ... even though standard recommendation is to keep SAP operation at 1.5M SSCH or less per second. This compares to recent announcement for single fiber-channel for e5-2600 that is capable of over million IOPS ... aka FICON is a layer built on top of underlying fibre-channel that enormously cuts fibre-channel throughput ... aka two of the e5-2600 fibre-channel would more than match the throughput of the z196 104 FICONs

from discussion
max z10 has 64 processors and rated at 30BIPS or 469MIPS/processor max z196 has 80 processors and rated at 50BIPS or 625MIPS/processor max ec12 has 101 processors and rating of 75BIPS or 743MIPS/processor
part of improvement in aggregate BIPS rate is more processors. improvement in per core-processor MIPS rate has been slowly increasing ghz. However, major improvement from z10 to z196 is introduction of out-of-order instruction processing (something that has been in risc processor for decades to help mask cache miss latency ... and recent generations of i86 processors have gone to risc cores with hardware layer that translates i86 instructions into risc micro-ops).
part of improvement from z196 to ec12 is further improvements in out-of-order execution support (branch prediction, speculative execution, etc).
for DBMS / i/o intensive ... ec12 is claiming only 30% improvement over z196 (while raw processing is 50%). much of this could be the additional processing power w/o any significant change in i/o throughput.
the linkedin/mainframe discussion goes into some detail about mainframe FICON and the inefficiencies introduced compared to underlying fibre-channel standard. IBM articles show that they appear to partial compensated for those inefficiencies with recent zHPF and TCW ... but also says that there has been no change going from z196 to ec12.
any potential for significant change appears to be financial and other incentives to have application utilize mainframe "specialty" processors (i.e. have been added to the environment ... that are other than the traditional "main" processors) that are increasingly being used in the mainframe environment.
this beginning to look more & more like this effort I had circa 1985 to

after the demise of the future system effort ... there was mad rush to
get products back into the 370 pipeline. POK kicked off 303x effort in
parallel with 3081&370xa. Endicott kicked off 138/148 in parallel with
e-machines (becoming 4331 & 4341). past posts mentioning FS
https://www.garlic.com/~lynn/submain.html#futuresys
138/148 were follow-on to 135/145. they had microcode space and had put
some stuff in microcode for vs1 (ECPS) that they thot might improve
thruput (but didn't actually have any hard&fast
information/criteria).. I then got roped into helping them with doing
something similar for vm370 ... I was told that there was 6kbytes left
(after what was taken up by ECPS for VS1). For this I did several runs
that did detailed analysis of where vm370 kernel was spending its time,
organized by instruction paths ... and sorted by percent use. It was
then "lopped" off at 6kbyte (kernel 370 instructions dropped into
microcode on approx. byte-for-byte basis ... even tho microcode was
completely different instruction set than 370). some of the results
reproduced here ... that resulted in things selected for vm370 ECPS
https://www.garlic.com/~lynn/94.html#21
these machines avg. approx. ten microcode instructions per emulated 370 instruction ... so when dropped directly into native microcode, it ran approx. ten times faster. The 6kbyte threshhold accounted for approx. 80% of vm370 kernel execution time ... so dropped into microcode it was speeded up by a factor of ten times.
endicott also con'ed me into going around to the marketing and product forcasting groups as part of justifying 138/148. One of the things I found was that domestic US forcasting tended to follow hdqtrs strategic direction ... since forcasting didn't actually result in anything except showing that you were toeing what ever corporate direction. By comparison the non-US forcasting was significantly more reliable since countries ordered machines from manufacturing and they were shipped to the country ... mis-forcasts were responsibility of the forcasting group and country (by comparison in the US, machines shipped directly to customer and mis-forcasts had to be eaten by the manufacturing plant ... as a result, manufacturing always redid their own product forcasts for the US).
Non-us said that without something unique, the forcast for 138/148 was nearly zero ... because of clone competition outside of the US. By comparison, US forcasting was that there was a set formula for 138/148 sales regardless of the features. Endicott attempted to make every 138/148 sold a vm370 machine (installed at the factory) ... sort of an earlier version of the mainframe LPAR facility ... to help with clone competition. They were shot down badly by corporate ... which was in the process of killing the vm370 product ... having been convinced by POK that it was necessary to kill vm370, shutdown the group and move all the people to POK or otherwise POK wouldn't be able to ship MVS/XA on schedule.
As a result 138/148 had vm370 ship as optional feature ... along with vm370 ECPS ... but VS1 did ship with VM370 handshaking (i.e. on a virtual machine page fault, vm370 could reflect a psuedo page fault to VS1 allowing VS1 to perform task-switch ... and then later vm370 reflect a psuedo i/o interrupt indicating that the page was now available). There is a very gross analogy with out-of-order instruction execution (being able to switch to a different instruction while waiting for data for previous instruction because of cache miss).
Also, Endicott managed to save the vm370 product mission ... but had to reconsitute a vm370 development group from scratch.
4300s managed to show up in 1979 ... well before 3081 ... some old
4300 email
https://www.garlic.com/~lynn/lhwemail.html#43xx
It would run in either 370 mode or e-architecture mode (having been specifically designed for single address space dos and vs1). Also the ECPS microcode "assists" from 138/148 were carried forward to 4331/4341.
I have no idea how many machines ran in e-architecture mode ... or whether most of them continued running in straight 370 mode (all the vm370 43xx machines of course ran in 370 mode ... since a unique virtual address space was used for every virtual machine).
43xx machines sold into the same mid-range market as vax/vms and in
similar numbers for orders of one or few machines. big difference for
43xx were the large corporate multi-hundred machine orders ... sort of
the leading edge of the distributed computing tsunami. old post with
decade of vax numbers sliced&diced in various ways.
https://www.garlic.com/~lynn/2002f.html#0
the 43xx sales did represent something of threat to the POK 3033 sales. distributed computing tsunami was siphoning a lot of computing from datacenter ... slowing datacenter growth. However, a 4341 cluster was better price/performance, larger aggregate processing, larger aggregate i/o, smaller space footprint, smaller environmental footprint, etc. This was at a time when many datacenters were feeling space/environmental crunch with the large POK machines ... with both distributed 4341 and 4341 clusters providing relief.
At one point, POK responded to the 4341 threat by getting corporate to cut allocation for critical 4341 manufacturing component in half.

The lock could be transferred over communication link ... but the actual record could only move through disk. I did a bunch of stuff so that I could do memory-to-memory transfer of DBMS record that piggy-backed on the same transmission that moved lock ownership.
However, the DBMS vendors were very apprehensive about actually doing it. In the case where fast-commit was disabled in multi-system environment, recovery for any record required at most a single log. Where fast-commit was allowed for multi-system environment ... with direct memory to memory transfers w/o requiring disk write/read ... recovery would require mult-log merge ... and the log records had to merge in the same exact sequence as the original transaction order.
It wasn't until the past couple years ... that vendors have gotten sufficiently confident about correctly doing recovery with multi-log merge (it use to be peoples' eyes would tend to glaze over as you get deep into the sequence of correct multi-log merge).

something that arpanet/internet didn't get until the great conversion
from imp/host protocol to internetworking protocol on 1JAN1983 ... at
a time when it had about 100 IMP networking nodes and possibly 250
connected hosts ... by comparison the internal network was on the
verge of passing 1000 nodes. Past post with some of the network node

the original arpanet/internet ... it had limitation on number of
network node definitions ... way less than the number of nodes in the
internal network ... and what is worse, HASP/JES would discard traffic
when either the originating node and/or the destination node wasn't in
the local table definitions ... as a result a MVS system couldn't be
trusted as a backbone node ... since it would be guaranteed to
arbitrarily discard traffic (MVS systems could only be trusted as
boundary nodes where they there were limited to discarding traffic
where they were the destination ... but the origin node wasn't defined
in their local table). misc. past posts mentioning hasp &/or hasp/jes
networking (nji/nje)
https://www.garlic.com/~lynn/submain.html#hasp
The internal network was also non-SNA ... at least until its great
change-over in the late 80s ... at a point when it would have been
enormously more cost-effective and productive to have moved over to
TCP/IP ... something akin to what BITNET-II did. misc past posts

Government Sues Wells Fargo for 'Reckless' Lending; Suit charges the

http://www.consumeraffairs.com/wells-fargo-news
from above:
As also alleged, Wells Fargo's bonus incentive plan -- rewarding
employees based on the sheer number of loans approved -- was an
accelerant to a fire already burning, as quality repeatedly took a
back seat to quantity. ... At issue are more than 100,000 FHA-backed
loans. Wells Fargo said the loans met federal lending guidelines when
half of them didn't, the government alleges.

... she goes into some of her perspective that OCC, Federal Reserve and Sec. of Treasury allowed whole slew of things to go on ... some of it interfering with things that should have been under control of FDIC ... but also allowing other things totally outside of the control of the FDIC ... i.e. loan originators by non-depository institutions ... being packaged as securitized instruments and sold through wallstreet ... all outside of traditional banking structure (i.e. not using deposits as source of funds for making the loans ... but using the immediate sell-off of the toxic CDOs as maintaining source of funds to keep the loans primed). In other cases ... traditional bankng operations may have been booking the loans ... but again they weren't relying on deposits as source of funds ... so the FDIC audits with regard to deposits being at risk didn't come come into play.
One of the suggestions was to eliminate OCC ... since during the bubble they were so aligned ("captured") by their financial institutions to not provide any effective regulation ... then give FDIC regulatory/audit responsibility for all traditional banking operations ... and if too-big-to-fail is to continue (and not bring back Glass-Steagall) ... give Federal Reserve responsibility for the non-depository parts of bank holding companies.
As mentioned numerous times before SEC was effectively doing little or nothing last decade (example of some number of repeated settlements with various institutions were they were fined, promised to stop doing the bad stuff ... which they continued to do anyway ... the basis for the comments that the fines were so small compared to the sums involved ... that it effectively became viewed as cost of doing business).
This is case were SEC appeared to not being doing stuff on what might have been illegal short activity:

from above:
Watsa's only sin was in being a little too early with his prediction
that the era of credit expansion would end badly. This is what he said
in Fairfax's 2003 annual report: "It seems to us that securitization
eliminates the incentive for the originator of [a] loan to be credit
sensitive. Prior to securitization, the dealer would be very concerned
about who was given credit to buy an automobile. With securitization,
the dealer (almost) does not care."

At least the straight through processing efforts with parallelizing technologies for the "killer micros" ... I did the speeds&feeds analysis early on and predicted that it wouldn't work ... but they were so enamored of their toys and toy demos they all kept charging ahead (never even doing any kind of their own speeds&feeds ... even rough ballpark).
I then got roped into doing major performance analysis & improvement on nearly 500k statement cobol application that ran these overnight settlement on 40+ max configured mainframes (>$30m per, i.e. number required to finish within the overnight window) ... no machine over 18months old. It had very large performance group that had been caring for the application for decades ... but they got somewhat myopic in what they were examining. I applied some other kinds of analysis to come up with some major improvements that had grown up over the decades.
In the middle of the last decade to financial industry group, I came back with another approach to do the re-engineering & parallelization ... all based on RDBMS & SQL (platform agnostic) ... including business rule based front-end. Initially the industry group was very excited ... but then the effort got shutdown ... comments was that there were still extensive scars left over in the executive ranks from the failed efforts from the 90s ... and it would take another generation or two before they had appetite to try again.
for other topic drift ... some old email mentioning effort that I had
from 1985 to support arbitrary mixes of 370 processors and other types
of processors in large number of racks:
https://www.garlic.com/~lynn/2011b.html#email850314 .
https://www.garlic.com/~lynn/2007d.html#email850315
I had also been working with NSF on what was to become NSFNET backbone
(operational precursor to modern internet) and had to chose between
rack/cluster meeting along with getting somebody else to make my
presentation to the director of NSF ... old email
https://www.garlic.com/~lynn/lhwemail.html#nsfnet
As mentioned upthread, one of the big boosts in last few generations of i86 thruput was the migration to risc core with hardware layer that translates i86 instructions to risc micro-ops. Something similar can be seen for z196 & zEC12 with increasing incorporation of out-of-order execution ... something that has been part of risc for decades.
Note the above calculation, I used IBM's base list price for e5-2600 blades. The big cloud vendors have been saying their scale-of-operation is such that they have started doing their own assembly with careful choice of components (price/performance, lifetime TCO, etc) ... and are doing it for 1/3rd the cost of brand-name systems. The above calculations for million times difference in cost/BIPS may be closer to 3 million times difference when just considering the large cloud mega-datacenter operations.
Any statements about death of PC is related to the consumer boxes ... with migration to much smaller personal devices connected to the large cloud mega-datacenters.

Mitnick at history conference
http://blog.usni.org/2012/10/16/social-engineering-kevin-mitnick-history-conference
I'm not sure why it was history(?) conference, even Mitnick had little about history ... mostly about his security/PEN business. I don't remember it being on "take-down" book ... but part of the tracking was there was lots of his stuff going on NETCOM which had recently converted from (10mbit) ethernet to (100mbit) FDDI and the existing tools for scanning traffic couldn't keep up with FDDI rate and had to be rewritten to handle FDDI speeds.
One of panel was FS-ISAC mentions commercial banking hacks ... another one yesterday. At the presidential critical infrastructure protection meetings one of the biggest concerns about ISAC was the info leaking to the public, not because the bad guys would use it, because the public would find out how bad it was. In 1995, the industry was saying that commercial banking would never move to the internet because of a long list of vulnerabilities. Not one of the exploits since then wasn't on the original list (& by 1999 there were countermeasures for everyone of the exploits, for various reasons not deployed)
The lack of action over data breaches and the public victims from the resulting fraudulent financial transactions was one of the major reasons behind the cal. state data breach notification act ... some hope that the publicity would motivate corrective action and countermeasures (approx. half of the federal data breach bills since then would mostly eliminate requirement for notification).
PCI-DSS was created after the data breach notification legislation and has been used in arguments that notification is no longer needed. One of the criteria for PCI-DSS certification is not having a breach ... aka after having a breach, certification is revoked.
I periodically pontificate that the process is severaly mis-aligned and even if the planet is buried under miles of information hiding encryption, it still couldn't stop leaks (in part because the info is needed in dozens of business processes at millions of locations around the world).
Disclaimer: in the mid-90s, I helped draft an industry standard that
slightly tweaks the current paradigm and eliminates crooks ability to
use leaked information for fraudulent financial transactions (and
there-for eliminates the motivation for majority of current breaches)
... it also significantly levels/flattens/commoditizes the trust
landscape ... however there are significant stakeholders with enormous
vested interest in the current status quo. old random trusted

About the time Boyd was at NKP, I was brought in to help setup Boeing Computer Services ... installation of 360/67 and CP67 online services at hdqtrs off Boeing field. I would also have to periodic visit Renton datacenter which I thought (at the time) was possibly the largest in the world ... claiming something like $300M (in 1969 dollars) of IBM equipment. Summer of 1969 there was always pieces of 2-3 360/65s being staged in the halls around the datacenter waiting to be installed (arriving faster than they could be put on the floor). There was also disaster scenario where Mt. Rainier heats up resulting in monstrous mudslide that takes out the Renton datacenter ... so it was in the process of being replicated at the new 747 plant in Everett (business case that a week w/o Renton datacenter would cost the company more than the cost of the Renton datacenter). Also summer of 1969, 747 #3 could be seen flying Seattle skies for FAA certification.
In 1990 commandant of Marine Corps leverages Boyd to remake marine corp and there are now yearly meetings at Marine Corps univ to discuss how things are going (just last week). Last year that commandant wandered into the meetings and spoke for two hours (hadn't been on the agenda, but nobody was going to stop him). cheney also credit's Boyd with battle plan for desert storm.

generally gui vis-a-vis cli (command line interface) comes up somewhat orthogonal to 3270. lot of 3270 started out sort of like glass-tty ... line interface on screen. later additional fullscreen interfaces (like editors) and menu interfaces.
the menu interfaces have been characterized a much more context rich interface ... especially for non-professional dataprocessing users. PROFS collected a bunch of cli applications and wrapped menus around them. initially inside the company it exploded the use by factor of at least ten times (aka most of the corporation was non-professional dataprocessing users). A professional dataprocessing expert can frequently be much more efficient with cli than with gui/menu. The "fullscreen" operation on 3270 (like original fullscreen editors) ... has been orthogonal to menu-mode operation.
There are a lot of gui/cli issues on one axis .... that is different axis from the 3270/non-3270 axis. lots of gui/cli issues can apply to whether it is a 3270 or non-3270.
So this is recent ibm-main discussion about .2second response
... minimum requirement for interactive computing ... the transition
from channel attached 3272/3277 to 3274/3278 made it impossible to
have interactive computing (similarly MVS made any kind of 3270
impossible for interactive computing). Detailed complaints to
3274/3278 product group came back with comment that 3274/3278 weren't
designed for interactive computing but for data entry.
https://www.garlic.com/~lynn/2012m.html#37
this is recent ibm-main post about circa 1980 STL bldg. overflowing
and 300 people from the IMS group were moved to offsite bldg. They
were offered "remote" 3270s and basically had a revolt. I got con'ed
into implementing channel extender that put channel attached, local
3270 controllers at the remote bldg ... giving the IMS group vm370/cms
interactive computing (they couldn't tell difference between response
on real channel attached and channel-extender attached)
https://www.garlic.com/~lynn/2012m.html#11
now there are some number of applications that have similar characteristics to that of 3270-menu type systems (including some number of browser-based menu applications) that run on fancy gui terminals. there are also some number of 3270 simulators running in separate teminal emulator windows that run on fancy gui terminals.
Some number of old-time 3270-based applications have gone thru some degree of maturity for certain class of human interactions (and require 3270 simulation to continue running) ... and their human factors compare favorably with some more recent, less mature implementations. Theoretically it would be possible to exactly reproduce the layout and interactions of those 3270-based applications w/o requiring the associated 3270 terminal simulation (there are relatively few real 3270s still in existence).

at least part of the "impossible" was that they had possibly 800 people doing manual care&support of their current paradigm ... which in large part contributed to changing the paradigm , allowing the ten impossible things (and also eliminated the need for those 800; aka the executive in charge would have lost their empire).
turns out this particular operation was organized so that actual air passenger traffic wasn't the profit maker ... while reservation/ticket selling made most of the money. The air passenger traffic (actually flying passengers) could loose money, but the parent company could still be profitable from the money on the reservation/ticket side.

the publicity would motivate corrective action and countermeasures

eliminate requirement for notification).
PCI-DSS was created after the data breach notification legislation and
has been used in arguments that notification is no longer needed. One of
the criteria for PCI-DSS certification is not having a breach ... aka
after having a breach, certification is revoked.

The new latest thing is downturn in PCs because of the migration to portable personal devices with wireless connection to the cloud.
IBM had attempted something in the late 80s with SAA ... but didn't succeed. In that time frame, a senior disk engineer got a talk scheduled at the internal, world-wide, annual, communication group conference and opened with the statement that the communication group was going to be responsible for the demise of the disk division. The issue was that the communication group was desperately trying to preserve their terminal emulation install base, fighting off client/server, distributed computing, etc. The disk division was seeing enormous amounts of data fleeing the datacenters because of the stranglehold that the communication group had. The disk division had come up with several products to address the problem ... allowing data to remain in the datacenter (sort of the current cloud) ... but since the communication group "owned" strategic responsibility for everything that crossed the datacenter walls ... the communication group could constantly veto whatever the disk division came up with.
misc. past posts on the subject:

here is a totally different TSO/ISPF comparison with vm/cms.
the 23jun69 unbundling announcement was very traumatic to many parts
of the corporation. "application" code not only had to be sold ... but
the price had to cover the cost. the idea of cost effective
development was very foreign to many parts of the
corporation. however, there was a loophole, a development organization
could show that their software revenue had to cover their development
costs ... which could be done with bookkeeping across multiple
applications. misc. past posts mentioning unbundling
https://www.garlic.com/~lynn/submain.html#unbundle
The first case I'm aware of was JES2 NJI networking. Typically company
did high, medium, and low price sale price ... and then see if the
resulting forecast numbers (times the price) covered the development
cost (i.e. lower price could significantly increase forecast meaning
more aggregate revenue than a higher price). JES2 NJI networking had
no price point that resulting in covering development costs. There was
the internal vm370 networking that they were never going to announce
(POK was in the process of convincing corporate to kill vm370 product,
shutdown the development group and move all the people to POK or
otherwise POK wouldn't be able to meet the MVS/XA ship schedule
... Endicott eventually managed to save the vm370 product mission, but
had to recreate a development group from scratch). A price for vm370
networking of nearly zero would still cover all vm370 development
costs. The JES2 NJI group cut a deal where they could have a "joint"
announcement. A fairly high price for the "joint" product resulted in
a combined forecast that covered the JES2 NJI development&support
costs. misc. past posts mentioning HASP, JES2, NJI, networking, etc
https://www.garlic.com/~lynn/submain.html#hasp
A couple years later, the bookkeeping got more relaxed ... two products just had to be in the same development group. The VM370 performance products was earning about the same revenue as TSO/ISPF and only had 3 people supporting ... while TSO/ISPF had a couple hundred people. They merge the two products into the same development group and effectively cut nearly all work on VM370 performance products ... so all that revenue could go to underwriting TSO/ISPF.
Lots of people may have been exposed to CMS IOS3270 menu w/o realizing it. The 3090 service processor was actually a pair of 4361s running a highly customized version of VM370 Release 6 and all the service processor menu screens were written in CMS IOS3270.
There was also a simulated "green card" written in IOS3270 that was
used extensively inside the company. I've recently done a rough

what x9.59 financial industry standard did ... some references

I have final authority on all details on webserver to payment gateway and did various requirements about the browser to webserver interface ... but not final authority. Several of the browser/webserver security requirements were almost immediately violated.

We do detailed end-to-end threat&vulnerability studies of various retail payment mechanisms in different environments as part of coming up with a secure solution standard for *ALL* retail payments.

old email from the 3092 (service processor) group
https://www.garlic.com/~lynn/2010e.html#email861031
https://www.garlic.com/~lynn/2010e.html#email861223
I had much earlier done some stuff with the manager that originally kicked off the 3092 service processor implementation ... as an alternative to what had been done for the 3081.
I had also introduced adventure inside ibm ... it had migrated to Stanford DEC10 machine and then been brought over to TYMSHARE's DEC10 machine (tymshare was large online vm370/cms commercial service bureau) and then ported to their vm370/cms system. Folklore was at one point TYMSHARE's CEO ordered that all games/non-business apps be removed from TYMSHARE ... until somebody told him that 30% of TYMSHARE's revenue was people playing games.
TYMSHARE started hosting free online VMSHARE discussion groups in
AUG1976 (for SHARE organization) and very early on, I got process
setup to get periodic copies of all VMSHARE to make them available on
the internal network. vmshare archives
http://vm.marist.edu/~vmshare
sometimes(?) "404" ... but also at wayback machine
http://vm.marist.edu/~vmshare/
One of the systems I put VMSHARE files on was the internal HONE online vm370 world-wide sales&marketing support systems. I got early questions about why would HONE do that for me. They didn't realize that one of my hobbies had been providing highly enhanced production operating systems for internal datacenters ... and HONE had been one of my longtime customers since cp67 days (when HONE clones started being put up around the world ... I got my first trips outside the country to do various of the installations for them).
... not that ... but the author of rexx around 1980 did a multi-user spacewar game that ran on vm370/cms 3270. client code ran under cms driving 3270 interface and interacting with the spacewar "server" to coordinate all players activity. clients used "spm" interface to talk to spacewar server ... which was supported by vm370 networking ... so that players could be anyplace on the internal network. Problem was that fairly early some people wrote automated (robot) players and came to quickly dominate the games ... being able to do moves & firing much faster than human players. eventually the spacewar server was changed to increase energy use inversely proportional to interval between a players move ... somewhat leveling the playing field between robot and human players.
ibm had convinced lots of places to order 360/67 (effecitvely 360/65 with virtual memory hardware) for running tss/360. When tss/360 ran into lots of difficulties various places did their own virtual memory systems. Univ. of Michigan did (virtual memory) MTS, Stanford did Orvyl (and wilbur ran under orvyl), science center had done cp40 on 360/40 with special hardware mods for virtual memory ... and then when 360/67 become available cp40 morphed into cp67 (and much later into vm370). At some pointer Wilbur was ported to MVS.
Note that the first webserver outside europe was on the (stanford)
SLAC vm370 system
https://ahro.slac.stanford.edu/wwwslac-exhibit
part of the issue was mainframe tcp/ip support. The original product
was on vm370 implemented in pascal/vs ... had some performance issues
only getting 44kbytes/sec using nearly full 3090 processor. I did the
enhancements for rfc1044 support and in some tuning tests at cray
research got channel thruput between 4341 and cray (possibly 500 times
improvement in bytes moved per instruction executed). some past posts
mentioning rfc1044 support:
https://www.garlic.com/~lynn/subnetwork.html#1044
The base vm implementation was ported to MVS by implementing simulation of some vm370 kernel functions. Later I was working on tcp/ip implementation that had 5000 instruction pathlength and five buffer copies. This was compared to VTAM lu6.2 at 160k instruction pathlengths and 15 buffer copies.
A tcp/ip implementation in vtam was subcontracted out ... initially it was faster than lu6.2. The contractor was then told that everybody "knows" a correct tcp/ip implementation is slower than lu6.2 and ibm was only going to pay for a correct implementation.
Part of the issue why internal development (even major mvs oriented components) preferred local direct channel attached 3270s vm370/cms systems ... even vm/vtam channel attached 3270s significantly slowed things down ... and mvs was enormously worse (as mentioned upthread about 300 from ims group getting moved to offsite building)

Cross-over reference to post in this group discussion mentioning SAA
http://lnkd.in/bMXsgv
and
https://www.garlic.com/~lynn/2012n.html#64
middle of 90s, a discussion asked what was the origin of middleware
https://www.garlic.com/~lynn/96.html#16 .
https://www.garlic.com/~lynn/96.html#17
in the SAA time-frame, there was a big gov. agency request for large
multi-campus dataprocessing environment. my wife was co-author of
response where 3-layer network & middle-layer was introduced ... some
of it specified what later is referred to as middleware. we were then
out making customer executive presentations on ethernet, (2-layer
network) client/server and (3-layer network) middle-layer ... part of
that presentation from the 80s:
https://www.garlic.com/~lynn/99.html#202 .
we were really being savaged by the token-ring and SAA forces (I've frequently characterized as trying to help preserve the terminal emulation install base) for doing those presentations ... lots of FUD and obfuscation. Token-ring forces came out with presentation about 16mbit t/r compared to ethernet. Their ethernet profile must have come from the original research 3mbit ethernet before CSMA/CD. The "new" Almaden research building had recently come online had been heavily provisioned with CAT4 supposedly for 16mbit T/R ... but they found 10mbit ethernet lan segment had both higher throughput as well as lower latency than 16mbit T/R.
Aggravating the issue was that SNA has no networking layer ... typical
16mbit T/R had 100-300 emulated 3270s sharing the same 16mbit with
bridges. The client/server would have ethernet and tcp/ip routers so
each 10mbit lan segment was separate. Some more pieces of the 3-tier
customer executive presentation ... showing cost comparison
https://www.garlic.com/~lynn/2002q.html#40
past posts mentioning originating 3-tier architecture
https://www.garlic.com/~lynn/subnetwork.html#3tier
Another example of the enormous pressure trying to preserve the terminal emulation install base was the implementation of the microchannel 16mbit T/R cards designed for terminal emulation and very low use per card. The workstation division PC/RT had (16bit) AT-bus and designed their own 4mbit T/R card. The RS/6000 had (32bit) microchannel bus and were forced to use PS2 cards (and corporate direction that they couldn't do their own). The PS2 microchannel 16mbit T/R card had lower per-card throughput than the PC/RT 4mbit T/R card (i.e. the severely restricted 16mbit T/R per card thruput helping limit doing much more than terminal emulation).

... repeat of some information referenced up thread:
max configured zEC12 briefs have its DBMS throughput at 30% more than
max configured z196 ... even though the processing rate is 50% more
than z196. Part of this can be interpreted as the I/O throughput
hasn't changed significantly from z196 (DBMS throughput increase
primarily from additional processing but possibly bottlenecked by
I/O).
The original FICON implementation severely restricted I/O throughput
of the underlying fibre-channel standard (going back to 1988). The
zHPF and TCW descriptions has it partially restoring to FICON some of
the underlying fibre-channel capability and throughput .... however
the documentation so far says that it is the same on zEC12 as z196.
max configured z196 has 80 processors rated at 50BIPS (and goes for
$28M). z196 peak benchmarks have 2m IOPS using 104 FICON channels, 14
storage subsystems and 14 system assist processors. However, SAP
reference has peak SSCH capacity of 2.2M/sec with all 14 SAPs running
at 100% utilization ... but recommendation is that SAPs are kept at
70% or lower utilization (i.e. peak 1.5M SSCH/sec).
A recent announcement has single fibre-channel for E5-2600 blade
capable of over million IOPS (aka two E5-2600 blade fibre channel
having more I/O thruput than 104 FICON channels). E5-2600 blade have
527BIPS rating and IBM base list price of $1815. An IBM blade chassis
holds something like 12 blades ... and possible to get something like
3 or 4 chassis in single rack ... possibly 48 blades in single rack
with aggregate processing rate of 25,296BIPS (and around $90K
... compared to 50BIPS and $28M for z196)
.... snip ...
Note that real CKD havn't been manufactured for decades ... being an extra overhead emulation layer built on top of industry standard "fixed-block" disks ... note that all other things being equal ... having the extra emulation layer would introduce additional throughput degradation ... compared to systems directly using the disks.
I've frequently pontificated about long ago and far away offering FBA support and was told that even if I gave them fully integrated and tested FBA support, I still needed a $26M business case to cover education, training and publications ... and I wasn't able to use total lifetime costs ... only incremental new sales. To cover the $26M, I would need something like $300M new sales ... but was told (at the time) disks were selling as fast as they could be made, and any FBA support would result in customers switching from CKD to same amount of FBA.
Elsewhere, there is the comment about company makes much more on mainframe sevices, software, and storage than on direct computer ... in effect $6.25 total for every dollar in direct computer sales ... for $28M z196 that comes to $175M large cloud operations

The zHPF and TCW descriptions has it partially restoring to FICON some of the underlying fibre-channel capability and throughput .... however the documentation so far says that it is the same on zEC12 as z196.
max configured z196 has 80 processors rated at 50BIPS (and goes for $28M). z196 peak benchmarks have 2m IOPS using 104 FICON channels, 14 storage subsystems and 14 system assist processors. However, SAP reference has peak SSCH capacity of 2.2M/sec with all 14 SAPs running at 100% utilization ... but recommendation is that SAPs are kept at 70% or lower utilization (i.e. peak 1.5M SSCH/sec).
A recent announcement has single fibre-channel for E5-2600 blade capable of over million IOPS (aka two E5-2600 blade fibre channel having more I/O thruput than 104 FICON channels). E5-2600 blade have 527BIPS rating and IBM base list price of $1815. An IBM blade chassis holds something like 12 blades ... and possible to get something like 3 or 4 chassis in single rack ... possibly 48 blades in single rack with aggregate processing rate of 25,296BIPS (and around $90K ... compared to 50BIPS and $28M for z196)

in the late 90s, I would makes offhand comments at security presentations that I would take $500 milspec piece, aggresively cost reduce by 2-3 orders of magnitude while making it more secure.
it was a generalized authentication trust mechanisms across all environments. there was issue if all environments went to chip-based authentication (aka something you have, in lieu of passwords and other mechanisms) ... people would need unique chip/card for every current pin/password they currently carry (large scores if not hundreds).
so the next step was changing from institutional-centric paradigm (one per institution per person) to person-centric paradigm (one per person) ... achieving 2-3 order of magnitude reduction per chip and 2-3 order of magnitude reduction in number of chips (overall 4-6 order of magnitude).
the issue then becomes if I present a person chipcard to my financial institution, government agencies, corporate door entry, etc ... what is required for all these institutions to trust the person-presented chipcard.
bunch of patents ... all assigned (we have no interest) including what
is necessary to do in order to get large institutions to trust a person
presented authentication device (i.e. move from institutional-centric
trust model to person-centric trust model)
https://www.garlic.com/~lynn/aadssummary.htm
the patents were interesting ... we were working with boutique patent firm and we had over 50 patents and they said there would be well over 100 before we were done. the executives looked at cost of filing so many patents and directed all claims be repackaged into nine patents. Later the patent office came back and said that they were tired of these humongous patents where the filing fee didn't even cover the cost of reading the claims ... and the nine patents had to be repackaged in at least 30 patents.
lots of past posts on the general 3-factor authentication model
https://www.garlic.com/~lynn/subintegrity.html#3factor
as previous mentioned the current payment paradigm requires hiding
information (encryption) as countermeasure to fraud ... and what was
adopted for "electronic commerce" ... with SSL. In the x9.59 model, the
only thing required is strong authentication ... and eliminates any
requirement to hide information. I've periodically commented that the
largest use of SSL in the world today is "electronic commerce" ... and
the x9.59 standard eliminates the need to use SSL for encrypting/hiding
payment transaction information. misc. past posts mentioning x9.59
https://www.garlic.com/~lynn/subpubkey.html#x959
even with strong authentication (eliminating skimming & breaches as vulnerabilitity ... using information from previous transactions for other fraudulent financial transactions ... aka can be considered form of replay attack) ... there still can be compromised endpoints that leverage the present of valid authentication to perform a fraudulent transaction (asking the person to approve the displayed transaction, but executing a totally different transaction).
In the late 90s, EU created the FINREAD standard as countermeasure to
compromised endpoints being able to do transactions other than the ones
the person thought they were approving. There was some missteps in the
2000 timeframe that resulting in industry pulling back from deploying a
number of strong security technologies. misc. past posts mentioning

a lot of fraudulent financial activity tries not to be visible .... crooks, ngos, countries ... doesn't matter. crashing the system stops the flow of money. visibility might possibly be immature and/or misdirection
Person that had tried unsuccessfully for a decade to get the SEC to do something about Madoff testified in the congressional hearings that tips turn up 13times more fraud than audits ... and that SEC didn't have a tip hotline, but had a 1-800 line for corporations to complain about audits. He was also asked in the hearings if new regulations were required. He said that while new regulations might be required, much more important was transparency and visibility.
One of the things is that for ages, something like 70% of identity theft related financial compromises (account fraud) has involved insiders. The rise of the internet and public press about external hacks have been utilized by insiders for misdirection and obfuscation .... creating ambiguity whether it is insider and/or outsider.
As an aside, annual USNI history conference last week was on cyber ... but very little was history. one of the panels discussions had the head of FS-ISAC. I've pontificated in the USNI blog about the lack of historical related cyber at the conference

electronic payments have an "interchange fee" ... the merchant submits the transaction amount and gets back that amount minus the "interchange fee". for decades that fee has been prorated roughly proportional to the amount of fraud for the type of transactions ... with something like an order of magnitude difference between the lowest and highest fraud interchange fee.
US financial institutions have avg. nearly 40% of their bottom line from these fees. eliminating most current fraud and reducing interchange fee charged by order of magnitude could result in around 1/3rd cut to their bottom line.
this extends into secondary analysis. the current electronic payment paradigm is the low hanging fruit for crooks and is source of significant profit from interchange fees charged merchants. significantly changing the electronic payment security paradigm not only eliminates that significant profit ... it will also drive crooks to other areas for fraud (places where the financial institutions can't justify charging merchants a significant profit and need to shoulder all the burden)
