  • Japanese supercomputer takes world's fastest title from US

    A new Japanese supercomputer has taken the title of world's fastest away from the US.

    The NEC Earth Simulator processes data five times faster than its closest competitor.

    It works at a speed of 35,600 gigaflops compared to its closest rival, IBM's ASCI White, which runs at a speed of 7,226 gigaflops.

    A gigaflop equals a billion mathematical operations per second.

    The NEC Earth Simulator is as large as four tennis courts and creates a "virtual planet Earth" to predict climate patterns.

    Jack Dongarra, a University of Tennessee computer science professor, leads the group of researchers that tracks the world's 500 speediest computers.

    "This machine is more powerful than the 20 fastest computers in the US," Mr Dongarra said. "It's more powerful than all of the Department of Energy and Department of Defence computers together."

    Today's most popular supercomputers use a massively parallel processing system, in which thousands of mass-produced microprocessors are linked to solve complex problems.

    NEC calls the Earth Simulator a "vector parallel" computer, which combines parallel processing with vector processing.

    The TOP500 list is compiled by researchers at the University of Mannheim in Germany and the University of Tennessee. The list ranks computers by their performance on Dongarra's Linpack Benchmark, a standardised measure of a computer's speed at solving a "dense system of equations.

    According to the latest official figures, 43% of all statistics are totally worthless...

    If you want that running at home you have to have a big, biiiig, backyard!!!

    Wonder if it comes bundled with a Parhelia???

      Sure it can simulate global weather patterns, but how many FPS can it get in UT?

        probably not much faster, but the skybox in UT would be prettier.
        This sig is a shameless atempt to make my post look bigger.

          I wish we could settle on this as a more universal way of enumerating processor performance, though of course motherboard, chipset, system RAM, etc. all come into play. Then Intel couldn't play games with a high speed processor that does less work per clock cycle than AMD's offerings, spawning the model number system, etc etc.. It's all just a mess now..

              Your untapped power is 1.02 Gigaflops, which is approximately 11% of SGI Origin 2000 w/16 processors.
              This is with my dual P3/600. The algorithm is pretty basic though.. still assumes quite a bit, being based entirely upon processor speed. What processor at 600MHz though? a 4004? an EV7? what?

              Found an easy java linpack bench here:

                  I put dual 1.7ghz cpus:

                  Your untapped power is 2.89 Gigaflops, which is approximately 30% of SGI Origin 2000 w/16 processors.

                  Your untapped power is 2.89 Gigaflops, which is approximately 0% of ASCI White.
