Parallel Studio XE 2011 with VS 2010: Unable to use multiple cores and extra memory available for fast computation

211 Views

Hello all,

I am using Parallel Studio XE 2011 with VS 2010. I am trying to run one code with repetitive calculations. However, speed for entire computation is very slow. When I looked at CPU and memory usage it shows that half of the memory and CPU is not used. I tried to enable Configuration Properties ->Fortran -> Optimization -> Parallelization -> Yes (/QParallel) and Optimization->Maximize Speed. But still no improvement in performance was observed. Diagnostics reports are as follows:

1><;-1:-1;PGO;;0>
1> 1 FUNCTIONS HAD VALID STATIC PROFILES
1> IPO CURRENT QUALITY METRIC: 50.0%
1> IPO POSSIBLE QUALITY METRIC: 50.0%
1> IPO QUALITY METRIC RATIO: 100.0%

Can anybody help me to interpret this report and improve performance of my code?

What other options that I can try to speed up computations?

Please let me know,

Thank you,

Nik
