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

[Jeff Squyres (jsquyres)]

Mmm.  No, there's no Java binding for this one -- we didn't define an extension 
interface for the Java bindings.

Sorry!

Thank you Jeff. I guess there is no Java binding for this function.

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:

[OMPI users] Accessing Process Affinity within MPI Program

[Saliya Ekanayake]

Hi,

Is it possible to get information on the process affinity that's set in
mpirun command within the MPI program? For example I'd like to know the
number of cores that a given rank is bound to.

Thank you
