The technologies that are invented for super-computing class systems have a way of making their way over time into a machine that you *will* put under your desk. Both MMX and more Altivec (a beefier version of MMX that is in certain PowerPC processors including the ones in I think all current Macs) are based on vector processing technology and ideas originally designed by Seymore Cray in the 70's for the Cray I. So the answer is, everyone cares, even if nobody knows exactly why. I won't pretend that I know exactly what technology from current Crays will end up in desktop systems in 10 years, but *something* probably will. The same can be said for the technology that is in current SGI and IBM (etc) supercomputers.

    Generally the only way large supercomputers can be built in the USA is through government contracts. Industry is unwilling to pay more than $10 million for a large computer. The Department of Energy has been commisioning top-end computers ($10M to $100M) for weapons research and NOAA for weather forecasting.

    I am ambivalant about this. On one hand I want to see a petaflop computer by 2010. (Two 100 teraflop computers have contracted for the 2007 timeframe, so this is possible.) On the other hand I am suspicious that computer companies won't build these on their own and dont like the governement propping up weak computer companies.

      ASCI Platforms have been upwards of $200M. $90M for Red Storm is cheap!!

      As for corporate welfare, as long as Linpack and the Top500 list (http://www.top500.org) are used as the primary metric for success, this pork-barrel spending to duct-tape COTS products will continue. I thought it was over when they killed off MPPs, but ASCI has managed to keep the farce going.

      The general public doesn't really understand that these systems don't do any useful work; they're just there to keep the labs in the pissing contest for your tax dollars. And the moron tech-writers for New Mexico papers continue to lap up the crap Sandia and Los Alamos feed them. No one seems to question the validity of what the Lab PR people tell them; they're just soooo excited to have these monsters in their backyards.

  38. Distributed processing by SeanAhern · · Score: 2

    Distributed processing is only really good when the subproblems are separate enough that they can be calculated separately.

    Um...that's not really true. Certainly, distributed processing works like gangbusters when the problem is what's called "embarrassingly parallel". Things like Seti, or distributed ray tracing of a static scene scale perfectly on a distributed system.

    But there are lots of groups (the DOE national labs being some) that do distributed work on problems that are not embarrassingly parallel. The trick is making sure that you have a fast interconnect between the boxes, and can make use of that interconnect efficiently.

    In general, a simulation (including particle simulations) will break up a region of space into pieces, and each piece is calculated for a "time step" on a processor. Then they each determine if they need information from another processor, or if their information could be used by another. A collective communication then takes place to exchange what's needed. Rinse and repeat.

    If you do your work right, you get a scalable system, one where you can add processors and get a proportional increase in performance (or maximum problem size). If you don't do you work right, the system will not scale well.

    Distributed computing is being used for more and more things these days.
