Japanese 'K' Computer Now Fastest In The World
  • Profile picture of the author seasoned
    I HATE false advertising! This kind of "computer" doesn't scale well. And who REALLY makes the computers? This article is about fujitsu basically putting them into an MMP system. It is made up of 68,544 CPUs. SO, it can do 68,544 tasks simultaneously but one COMPLEX task may run FAR SLOWER! And you know what they say about 9 pregnant women! It STILL takes 9 months to have a kid!

      So it's not the fastest computer in the world??

        It's like the newer processors with the faster clocks. Doubling the clock doesn't make them twice as fast unless MAYBE they are efficient enough, and your code fits in the chips lowest level cache. Or the newer multicore processors. Put in six cores, and the software doesn't necessarily run six times as fast.

        Well, the article describes An MMP system that is almost like a very inefficient 68,544 core processor.

        So the raw power may be there, and it may add up to being so fast, but it isn't all usable.

        And they didn't even come up with that concept. I don't know who did, but IBM, INTEL, and OTHERS have been doing it for decades. Most have been much smaller, but some have been VERY large, and still had room for expansion.

        Who knows, the fujitsu one may even be smaller than some of the older ones, and simply use the newer faster CPUs.

        9 women certainly have more potential than one, and they could have kids an average of nine times as fast, but each kid will take an average of 9 months. The same is true of MMP systems. Unless you break up a task, and split it among the processors, that particular task will only use one CPU's potential.
