Standard STREAM Submission for IBM Power 750 Express

John,

I would like to submit this STREAM standard result for IBM Power 750
Express.

This system has four 3.3 GHz POWER7 processors with a total of 24 cores,
128 GB (32 x 4 GB) DDR3 1066 MHz, 32KBI+32KBD L1 on chip per core,
256KB L2 on chip per core, and 4MB L3 on chip per core.

This system also runs the following software:
- SUSE Linux Enterprise Server 11 for IBM POWER
- Libhugetlbfs 2.0
- IBM XL C/C++ for Linux, V10.1 updated with the Oct2009 PTF
- IBM XL Fortran for Linux, V12.1 updated with the Oct2009 PTF

Computer Array size SMT Triad score
-------------------------------------- ------------- --- -----------
IBM Power 750 Express (3.3 GHz POWER7) 1,789,569,700 off 122766.3208

Please make this result publicly available at your earliest convenience
for highlighting IBM Power 750 Express to be announced on February 8,
2010.

Let me know if you have any questions.

Thanks,
Peter

Your clock granularity/precision appears to be 1 microseconds.
Each test below will take on the order of 184026 microseconds.
   (= 184026 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.
