*NEWS*FASTEST SUPERCOMPUTER GETS FASTER

    Fastest supercomputer gets faster
    Blue Gene/L, the fastest supercomputer in the world, has broken
    its own speed record, reaching 135.5 teraflops-a trillion calculations a
    second.

    That is double the speed it clocked up to take it to the number one spot in
    the Top 500 supercomputer league.

    The IBM Blue Gene machine that achieved the new mark is being assembled for
    the Lawrence Livermore National Laboratory, a US Department of Energy (DOE) lab.

    It did 70.72 teraflops last year to beat Japan’s NEC Earth Simulator.

    The Blue Gene/L is due to be completed for the Livermore labs in 2005.





    WORLD TOP 5 SUPERCOMPUTERS

    1. Blue Gene/L, USA
    2. Columbia, USA
    3. Earth Simulator, Japan
    4. MareNostrum, Spain
    5. Thunder, USA

    Its peak theoretical performance is expected to be 360 teraflops,
    with the machine taking up 64 full racks.

    Blue Gene’s new record was achieved by doubling the number of current racks
    to 32. Each rack holds 1,024 processors, yet the chips are the same as those
    found in high-end computers on the High Street.

    The processors are special dual-processing engines, known as cores.
