Re: [OMPI users] Accessing Process Affinity within MPI Program

Sorry for the delay in answering this; this mail came after I disappeared for 
the US holidays.

Yes -- through an Open MPI extension (you must configure Open MPI with 
--enable-mpi-ext=affinity or --enable-mpi-ext=all).  See:

http://www.open-mpi.org/doc/v1.8/man3/OMPI_Affinity_str.3.php
