> I believe both OpenMPI and MPICH will work over the RxM and SHM providers I can't verify that the SHM provider works on either, but I don't think it's a compatibility issue (since it works on Intel MPI) but rather a configuration/setting issue with exposing the provider.

I don't know the specifics of what MPI requires. MPICH and OpenMPI are both flexible in what features they require, however, and usually default to a fairly minimal set. I believe both OpenMPI and MPICH will work over the RxM and SHM providers. (The owners of those components should be able to verify). If so, then this matrix will help identify which features are needed (though they may still implement more than what is required): https://github.com/ofiwg/libfabric/wiki/Provider-Feature-Matrix-master - Sean _______________________________________________ ofiwg mailing list [email protected] http://lists.openfabrics.org/mailman/listinfo/ofiwg
