      Here is a stream submission for HP's Itanium workstation. I'd appreciate
    if you could post it tonight.

    Please confirm you receive this (reply all since I'll be at home later). If
    you have any questions or need more information, please let me know.
    xxx-555-xxxx. cheers, Ian

    hp workstation i2000 800Mhz dual processor 2MB cache 8GB RAM
    Itanium processor
    HP-UX 11.20

    stream output:

    Double precision appears to have 16 digits of accuracy

    Assuming 8 bytes per DOUBLE PRECISION word


    Array size = 5000000

    Offset = 8

    The total memory requirement is 114 MB

    You are running each test 30 times


    The *best* time for each test is used

    *EXCLUDING* the first and last iterations


    Your clock granularity/precision appears to be 1 microsecond_s


    Function Rate (MB/s) Avg time Min time Max time

    Copy: 1159.3521 0.0692 0.0690 0.0702

    Scale: 1177.3877 0.0682 0.0679 0.0687

    Add: 1378.7075 0.0874 0.0870 0.0893

    Triad: 1403.2446 0.0859 0.0855 0.0884


    Solution Validates!


    compiled as follows:

    #! /bin/ksh

    echo compile stream

    rm streamf.out

    cc +O2 timerf.c -c

    f90 +noppu +O2 -Wl,+pd,64M streamf.f timerf.o -o streamf.out
