    Here are the results for a 'hp server rx2600' with:
      2 1000MHz Itanium 2 (3 MB cache) processors
      12GB memory (fully populated with 12 1024MB dimms)
      B.11.22 HPUX11i-TCOE (full listing of SW and tunable updates below)
      The following is a uniprocessor run

    % ./streams_f.uni
    ----------------------------------------------
     Double precision appears to have 16 digits of accuracy
     Assuming 8 bytes per DOUBLE PRECISION word
    ----------------------------------------------
     Array size = 10000000
     Offset = 0
     The total memory requirement is 228 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 1 microseconds
     ----------------------------------------------------
