[OMPI users] Pinning of openmpi to certain defined cores possible

[Vlad Popa]

Hello!

We habe a shared memory system based on  4CPUs of 12-core Opteron with a 
total of 256Gb RAM .

Are there any switches, which we could set , so that  when running   
mpirun-jobs  we'd be able to pin them down to a defined certain memory 
area and defined processor cores so that they stay there?

best regards
