Well Dave,

One interesting thing about it is that late last week, the House rejected an
amendment that would have revisited the MTOPS (millions of theoretical
operations per second) limit for exports of computers to so-called Tier III
countries like China and India.  The current MTOPS limit is, I believe,
19,000 MTOPS, and this story suggests they created a supercomputer capable
of 500,000 MTOPS with 70 PS2s.  Another twist, under the previous MTOPS
limit of 2,000, a single PS2 exceeded the export limit.  Bottom line --
MTOPS has probably outlived its usefulness, assuming terrorists can purchase
game consoles at Toys R Us, but Congress hasn't realized that yet.

Why is this new? While it is cute, so??? djf

>NY Times/CNET News -- As perhaps the clearest

>Supercomputing Applications at the University of Illinois

>although it may not rank among the world's 500 fastest
>supercomputers.

>the individual game
>machines in a rack and plugging them together with a high-speed
>Hewlett-Packard network
>switch.

>The center's scientists bought 100 machines but are holding 30 in reserve,
>possibly for
>high-resolution display application.

>who is one of four
>scientists working part time on the project.

>The scientists are taking advantage of a

>pixels rapidly on a television screen to
>produce lifelike graphics.

>That chip is not the PlayStation 2's MIPS

>co-processor known as the Emotion Engine.
>That custom-designed silicon chip is capable

>The impressive performance of the game
>machine, which has been on the market for
