John,

Below are STREAM results for the HP ProLiant DL385 (2 CPU), DL585 (4
CPU), BL25p (2 CPU), BL35p (2 CPU), and ML370 G4 (1 CPU). The
configurations are described below with the results:

HP ProLiant DL385
2x2.6GHz/1MB L2 252 Opteron processors
16GB PC3200 DDR memory (8x2GB DIMMs)
SuSE Linux Enterprise Server 9 (x86_64)

I used Revision 5.3 of the stream code and compiled with PGI C/C++ for
Linux v.5.2-4:

pgcc -O2 -Mvect=sse -Mnontemporal -Munsafe_par_align -mp -o ompstream
stream_omp.c

-------------------------------------------------------------
This system uses 8 bytes per DOUBLE PRECISION word.
-------------------------------------------------------------
Array size = 1000000, Offset = 49152
Total memory required = 22.9 MB.
Each test is run 10 times, but only
the *best* time for each is used.
-------------------------------------------------------------
Number of Threads requested = 2
Number of Threads requested = 2
-------------------------------------------------------------
Your clock granularity/precision appears to be 1 microseconds.
Each test below will take on the order of 4107 microseconds.
(= 4107 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.
