Supercomputer On the Cheap

jbrodkin writes "You don't need Ivy League-type cash to get a supercomputer anymore. Organizations with limited financial resources are snatching up IBM supercomputers now that Big Blue has lowered the price of Blue Gene/L. Alabama-Birmingham and other universities that previously couldn't afford such advanced technology are using supercomputers to cure diseases at the protein level and to solve equally challenging problems. IBM dropped the price of the Blue Gene/L to $800K late last year before releasing a more powerful model, Blue Gene/P, last month. Sales of Blue Gene/L have more than doubled since then, bringing supercomputing into more corners of the academic and research worlds."

          My experience says the hotswap turns to a dual cold shoulder; It has something to do with an error when malloc fails to make sufficient room to store correct name, or a null pointer is dereferenced when trying to remember name. Oh well. There's still hope.

          while(1)
          {
          myGirl = myGirl -> cuteFriend;
          delete myGirl -> last;

          myGirl -> isHappyEnding = !(myGirl -> isHappyEnding);

            // initialize variables
            myGirl = arg[0];
            acctbal = arg[1];
            girl_count = 1;

            date_cost = 20;
            while (!bored && !dumped) {
            date_success = date(date_cost);

            if (date_success) { date_cost = date_cost * 1.75; }
            else { dumped = true; }

        Nope, at least on the PS2 count (I don't know about Mac G5s). Back in 2000, Saddam Hussein was purchasing Sony PS2s by the thousands [freerepublic.com], which were then banned from export, due to them being classified as munitions.

        Certainly true that firing a PS2 out of a big gun was about the best thing you could do with them.
      • Way back when I was in jr. high around 1980, my friends and I were going ga-ga over the latest issue of Byte magazine at the library.

The 6502 (Apple II) and 8088 (IBM PC) were listed at less than 1000 FLOPS (they didn't do floating point so it had to be emulated in software). We were drooling over the Cray Supercomputer which was listed at 1 million FLOPS, or 1 MFLOPS.

        A 2.4 GHz Core 2 Duo rates around 500 MFLOPS. An nVidia 8600GT

        Every time there's an article on supercomputers someone brings up clusters. As has been pointed out before, a cluster only works for easily parallelizable problems where you can divide your problem into many subproblems that can be divided amongst your nodes. This is not a problem with supercomputers as you have much faster communications amongst processors (ie they're not just cheaply connected with cat5 ethernet cable like beowolf) and thus you can solve problems on a supercomputer much faster in this case.

        Supercompters aren't going anywhere fast.

      • I think the super computers are a thing of the past. Now days clusters are the way to go. Much cheaper and flexible.

        Yes, no, maybe.

        I guess the best definition of a cluster vs a "real" supercomputer is distributed memory connected via some kind of interconnect vs a large shared memory SMP. A blue gene is a distributed memory system connected via interconnects. The Cray XT4 and XT3 are distributed memory systems connected via interconnects. Actually, I think that SGI is the only guy that really makes large

      Although presumably the definition is revised up in terms of performance... It is not like everyone is sitting on old slow computers which suddenly become supercomputers by definition.

      Distributed processing is fine for "embarrassingly parallel" problems where the compute nodes don't need to communicate with each other. However, many problems solved by supercomputers or large clusters need communication between the compute nodes, so aren't amenable to distributed solutions.
      • A friend of mine once ran the massively parallel supercomputer centre at LaTrobe. He told me of how the transputer-based Connection Machine would run blindingly fast in parallel, only to have the lights slowly wink out until one small corner of the display was the only thing lit. He said it was disappointing, and rather funny, how parallel jobs tended to go linear over time.

        Yep, sometimes you just need a few processors running very fast cycles.

        Sigh... we miss you, Seymour Cray. Wish you hadn't taken your Jeep out that day.

        • That's the exact opposite end of the spectrum from embarrassingly parallel problems. In embarrassingly parallel problems you have so little data dependency that tasks can run independently or nearly independently. In you friend's case, the tasks were so interdependent that all the tasks were waiting on one task to finish, so there was nearly no speedup from adding more processors.

          The bottom line is that the best solution to some problems is a grid of loosely connected computers. The best solution to others

          The Connection Machine used up to 64K 1-bit processing elements configured to work lock-step with a single control unit (SIMD).

          The transputer was something completely different. It was a 32-bit processor with four high-speed connections to other transputers. This could be used to implement a MIMD processing network.

          The CM scaled well on data parallel applications, the transputer was more suited to course-grained parallelism.

      • That's why it's a pity that SGI (much as I dislike Irix) got so thoroughly thumped. Those 8-proc O2000 nodes connected into a distributed shared memory system which looked like a single, flat, address space for many purposes were nice machines, and relatively simple to program. Affordable BlueGenes, Altixes, and E25Ks (affordable being a relative term) are still useful due to their simpler to use shared design, over purely distributed code.

    Supercomputers and Mainframes are for totally different purposes.
    A supercomp will do one and only one job parallely to finish it off much faster than any other computer.
    A M/F can handle multiple jobs at the same time with lesser speed, but with considerable stability.

    For many companies, one S/390 running OS/390 or even an AS/400 (not related) is more than enough for their entire Notes setup.

    A supercomputer cannot be used to do that 24/7.

    They are fast racecars which cannot race outside of circuit.

  • These days, $800K for a supercomputer is going to be snapped up by financial institutions far faster than academic and research. Didn't Mitsubishi just close its research plant?

      If the price goes even lower, perhaps they will. I find it difficult to see this happening though: the financial firm I work for has swung from supercomputer to linux clusters, and is showing no signs of going back. The TCO for a bunch of linux blades is just so much lower than a supercomputer... and because banks are so conscious of their bottom lines, they usually don't improve things if they are already working.

    This has been a marketing ploy for decades: calling a supercomputer from a few years ago a cheap supercomputer. Well, its no longer a supercomputer.
