  Re: The Future of CPUs: What's After Multi-Core?

http://www.garlic.com/~lynn/2006w.html#46 The Future of CPUs: What's After Multi-Core?

lots of collected posts mentioning (global) page replacement
http://www.garlic.com/~lynn/subtopic.html#wsclock

a little more global LRU history. "Swapper" referred to what I've
called "big pages". The issue in "big pages" was how to collect
multiple pages (originally a 3380 tracks worth, ten pages) from the
same address space for transfer in single operation. It was much
easier to do something like "local" LRU ... to get a whole track of
pages (from the same address space) for a single track
transfer. however, that severely degraded performance with the
management of the pages in real memory.

from long ago and far away ... there was a lot of performance
measurements showing much improved performance by putting global
LRU back in ....

Hardware Forth implementations typically provide only a CALL/RET and
some sort of IF, ELSE, NEXT construct for loops - forms of JMP - but
not usually any programmer useable JMP, although it's normally possible
to simulate one if you feel the need.

  Securing financial transactions a high priority for 2007

Securing financial transactions a high priority for 2007
http://www.secureidnews.com/news/2006/12/22/securing-financial-transactions-a-high.../

Are we talking about the X9.59 financial standard?

In the mid-90s, the X9A10 financial standard working group was given
the requirement to preserve the integrity of the financial
infrastructure for all retail payments. The result was the X9.59
financial standard.
http://www.garlic.com/~lynn/x959.html#x959
http://www.garlic.com/~lynn/subpubkey.html#x959

or are we talking the infrastructure that has had the "yes card"
vulnerabilities (which started about the same time as the X9A10
working group)
http://www.garlic.com/~lynn/subintegrity.html#yescard

We had started work in the financial standard X9A10 working group
after having worked on server payment infrastructure
http://www.garlic.com/~lynn/aadsm5.htm#asrn2
http://www.garlic.com/~lynn/aadsm5.htm#asrn3

that has since come to be referred to as electronic commerce.

Some recent posts about various vulnerabilities in that infrastructure
(and which various parts of the x9.59 standards work from the mid-90s
was intended to address):

re:
http://www.garlic.com/~lynn/2006y.html#0 Why so little parallelism?

a little more archeological cross-over from thread in comp.arch

for other historical reference, when i was undergraduate in the 60s,
i had added the original tty/ascii terminal support to cp67 ... misc.
related postings about that somewhat leading to univ. project to
build our own mainframe clone controller
http://www.garlic.com/~lynn/subtopic.html#360pcm

other old email ... besides what was included in comp.arch posting
