25th TOP500 List Released 274

Chris Vaughan writes "The 25th edition of the TOP500 list of the world's fastest supercomputers was released today (June 22, 2005) at the 20th International Supercomputing Conference (ISC2005) in Heidelberg Germany. The No. 1 position was again claimed by the previously mentioned BlueGene/L System. At present, IBM and Hewlett-Packard sell the bulk of systems at all performance levels of the TOP500. The U.S is clearly the leading consumer of HPC systems with 294 of the 500 systems installed there (up from 267 six months ago)."

    It would be great if we could verify Moore's law through some simple stats using the histrical data from this Top500 list.
    -For example:How many years did it take for Number ones on average to be dropped off the 500 list?

    - How many years after the list was published did it take personal computers tu make it in the 500list? To make it to the number 1 spot?

    - How many transistors did these computers have? Did it verify Moore's law?

    - Are we getting more TFLOPS per watt now? Per transistor?
    etc..

    • Maybe we should measure computer performance in more practical terms. Maybe it should be a function of input and output. For how much work the user puts in, how much work does the computer put out? That is the real point of computing, having a machine do work for us, so perhaps it would help to measure power in more concrete terms.

        That's opening a whole can of worms really. A computer is just a tool, and this kind of measurement is simply not possible. As another example, take a screwdriver - pretty much anyone would agree that it's a tool that makes life easier, but you simply can't measure the output of a screwdriver.

      Why is that suprising in any way? At one time, Ford was synonymous with cars, but today have news of Ford laying off managers. IBM used to be synonymous with the desktop PC, but with the sale of their laptop division are now completely out of the market. Sony Walkman was synonymous with portable music, but now everyone has an iPod.

      Cray is just another company that had a great product for a while, but couldn't keep innovating and couldn't keep up when the competition joined the market. Nothing at all suprising about it, it happens all the time.

      Cray still makes some of the fastest supercomputers around. They do not, however, make supercomputing clusters, which this list includes.

      So you're comparing rather different things. And it's an important difference since not all computing tasks can be parallelized.

      It all depends on the system architecture and the type of problem being solved. Certain problems will adhere better to certain architectures and thus allow for a smaller gap between the theoretical and actual performance. The gaps can also be inherent in the architecture itself (e.g. communications bandwidth like you said).
      • Uh, for purposes of Top 500 List classification, they are all solving the same problem -- the High Performance Linpack benchmark (solving a system of simultaneous equations via Gaussian elimination with array pivoting). Granted, I beleive some variance in the size of the arrays is allowed, giving more massively parallel machines that can handle larger arrays an advantage.

    BlueGene/L max linpack: 136800

    The #1 linpack score is well over twice the #3 linpack score ?!?

    That fact combined with the large number of IBM-based systems on the to 100 list really makes it look like IBM is dominating this sector of the market.

    You know what data is always missing from this list that we'd all like to see ? The cost of the systems. Although, I suppose if you're looking at building the most powerful computer system on the planet, cost might not be your first consideration...

    • What I want to see is the list of ongoing costs. I see a tun of PIV's on the list but I wonder how much more it costs to use those PIV's say Athlon 64's ect. Every extra watt adds up.

      At ~10c per kilowatt hour * 95% uptime = 0.83$ / watt per CPU / year.
      So ~100w CPU * 65,000 CPU's * 3 years * 2 (AC costs) = around 3.2 mill on energy costs.

      Not that I expect them to dump the system in 3 years but the energy costs to run a system like that stop being worth it after a few years and then it's time to upgra
