 |
|
Hi,
Whenever I try to run an OpenMP program and set OMP_NUM_THREADS to 8 or more the application does not run correctly. When the application reaches an OMP call it aborts with the following message:
"OMP_NUM_THREADS or NCPUS value (8) is invalid"
Is this a known limitation of the PGI compiler and is there a way of getting around it?
The reason I am asking is that I have an application that I am going to run on a 8-way Opteron machine and it would be nice if I can actually use all the processors.
Best regards,
Peter |

Hi Peter,
The PGI workstation is limited to 4 CPUs. You'll need to upgrade to the PGI Server in order to run 8 CPUs. Please refer to our product page or contact sales at sales@pgroup.com for more information.
Thanks,
Mat |
