Subject: [OMPI users] Processor affinitiy
From: Alberto Giannetti (albertogiannetti_at_[hidden])

I would like to run one of my MPI processors to a single core on my
iMac Intel Core Duo system. I'm using release 1.2.4 on Darwin 8.11.1.
It looks like processor affinity is not supported for this kind of
configuration:

> v1.2.4)

Can I get processor affinity recompiling the distribution, maybe with
different option?
