Setting thread Affinity to Single Core

Setting thread Affinity to Single Core

Hi,

I couldn't understand from the doc how to limit my omp program to a single Core.

Basically I'm checking a program with 1 or 2 threads, and I want both threads to run on the same Core to see the advantages or hyperthreading.

There should be a simple KMP_AFFINITY to set, but I couldn't understand which.

Thanks,

Arik

For more complete information about compiler optimizations, see our Optimization Notice.

Also,

Is there a way to set the affinity to a specific core? As in if I want the program to run entirely on Core 0?

Arik,

You are asking your question on the wrong forum, as this one is dedicated to discussions on the Open Source run-time library.  General questions on the compiler behavior should be asked on the corresponding compiler forum.

I'll try to write some details on the question in personal e-mail.

Regards,
Andrey
