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:
$ ompi_info|grep affinity
MCA maffinity: first_use (MCA v1.0, API v1.0, Component
v1.2.4)
Open MPI: 1.2.4
Open MPI SVN revision: r16187
Open RTE: 1.2.4
Open RTE SVN revision: r16187
OPAL: 1.2.4

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