    Hi,

    I don't know if you are still updating the stream results table, but
    here's the score for my new server a Rackable C2004 with an ASUS
    PSCH-SR/IDE motherboard. 1GB RAM dual channel, Pentium4 3GHz 1M 800MHz
    FSB. The code is unmodified from your site and compiled with:

    gcc -O3 -march=prescott stream.c -o stream

    -------------------------------------------------------------
    This system uses 8 bytes per DOUBLE PRECISION word.
    -------------------------------------------------------------
    Array size = 2000000, Offset = 0
    Total memory required = 45.8 MB.
    Each test is run 10 times, but only
    the *best* time for each is used.
    -------------------------------------------------------------
    Your clock granularity/precision appears to be 5 microseconds.
    Each test below will take on the order of 8653 microseconds.
        (= 1730 clock ticks)
    Increase the size of the arrays if this shows that
    you are not getting at least 20 clock ticks per test.
    -------------------------------------------------------------
    WARNING -- The above is only a rough guideline.
    For best results, please be sure you know the
    precision of your system timer.
