Sandia Wants To Build Exaflop Computer

Posted by Soulskill on from the an-exaflop-ought-to-be-enough-for-anyone dept.

Dan100 brings us an announcement that Sandia and Oak Ridge National Laboratories are setting their sights on an exaflop supercomputer. Researchers from the two laboratories jointly launched the Institute for Advanced Architectures to facilitate development. One of the problems they hope to solve is how to provide each core of each processor with enough data so that cycles aren't going to waste. "The idea behind the institute — under consideration for a year and a half prior to its opening — is 'to close critical gaps between theoretical peak performance and actual performance on current supercomputers,' says Sandia project lead Sudip Dosanjh. 'We believe this can be done by developing novel and innovative computer architectures.' The institute is funded in FY08 by congressional mandate at $7.4 million."

    Aren't we getting a little bit ahead of ourselves, Sandia? What program would you run on this? This brings up the essential issue: what kind of program would YOU write to take advantage of this? I can only think of one: AI.

This brings up the essential issue: what kind of program would YOU write to take advantage of this? I can only think of one: AI. Military simulations. That's what Sandia spends most of its supercomputing clock cycles doing. The Department of Energy funds supercomputing centers like Sandia National Laboratories in order to run simulations on military vehicles, nuclear weapons simulations, etc.

      You don't usually run one program on these type of systems. The compute cycles are bidded out to researchers and they get x number of compute hours. The system is partitioned out to a few nodes and given to the researcher to run their codes on. You could have on a system like this hundreds of jobs running simultaneously. Also, with the tens of thousands of cores needed to reach this status, a node failure, or other hardware failure is inevitable. Right now if a node fails in the middle of the job, everything is lost from the last checkpoint. The chances of failures impeding work go up greatly the more nodes and cores you run the job on.

      What program would you run on this?

      I happen to work at Sandia and can assure you that much more than weapons work is done on the computers. In fact, recently a lot of work was done in modeling the huge asteroid that smashed into Russia in the early 20th century. The researchers we able to develop new understanding of the dynamics of such an event and discovered that much smaller asteroids than previously thought could do such damage.

      Also, a large portion of the computers are available to outside research (besides research done at the Labs).

    So far the advances in the field of AI have been non-spectacular. Yes, there have been somewhat succesful reasoning systems (rule based or probability based) and neural networks have made classification easier.

    However, at the moment there are no serious applications that will only become feasible by having more computer power.

    More speed in calculation has plenty of benefits, but AI as a research field will not be making major announcements soon because of this new machine.

  5. Not Build, only think about it by Guybrush_T · · Score: 4, Informative

    Reading the article, the goal is nowhere near building a real exaflop computer, but more about thinking about issues (like processor data feeding).

    In a year and a half, we shouln't have more than 100 GFlops per socket, which means that you will still need 10 millions of processors (not cores!) to achieve the exaflop computer. No chance to build a cluster that big (at least these years).

    The all-times progression of the top500 shows that exaflop computers should arrive around year 2020, definetly not tomorrow. (x10 every ~4 years, 2008:1 PF, 2012:10 PF, 2016:100 PF, 2020:1 EF)
