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