John,

I would like to submit this STREAM standard result for the IBM Power 575
system with
32 cores, 128 GB (64 x 2 GB) DDR2 667MHz, 32 4MB L2 caches and 16 32MB L3
caches.

The following pieces of software are installed on the machine:
- Red Hat Enterprise Linux Advanced Platform 5.2 for IBM POWER
- IBM XL Fortran Advanced Edition V11.1 for Linux
- IBM XL C/C++ Advanced Edition V9.0 for Linux

Computer Array size SMT Triad score
--------------------------------------- ------------ --- -----------
IBM Power 575 (4.7 GHz POWER6 RHEL 5.2) 1000,000,284 off 158638.8408
 
Please make this result publicly available at your earlier convenience for
highlighting
IBM Power 575 server and RHEL 5.2.

Let me know if you have any questions.

Thanks,
Peter

This system uses 8 bytes per DOUBLE PRECISION word.

Array size = 1000000284, Offset = 0
Total memory required = 22888.2 MB.
Each test is run 10 times, but only
the *best* time for each is used.

Your clock granularity/precision appears to be 1 microseconds.
Each test below will take on the order of 84836 microseconds.
   (= 84836 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.
