    Stream results for an 8 processor HP rp7410:

    ----------------------------------------------
    Double precision appears to have 16 digits of accuracy
    Assuming 8 bytes per DOUBLE PRECISION word
    ----------------------------------------------
    Array size = 53477820
    Offset = 0
    The total memory requirement is 1224 MB
    You are running each test 10 times

    --
    The *best* time for each test is used
    *EXCLUDING* the first and last iterations
    ----------------------------------------------------
    Your clock granularity/precision appears to be      2 microseconds
    ----------------------------------------------------
