OpenFabrics MPI listserve

I pinged this list a few months ago soliciting the MPI Forum for feedback creating a new low layer OpenFabrics network-agnostic API (see http://lists.mpi-forum.org/mpi-forum/2014/01/2693.php) After a round of gathering requirements and presenting them to the OpenFabrics Interfaces Working Group (OFIWG), steady progress is occurring. If you're interested in the MPI side of the work that the OFIWG is doing, please feel free to subscribe to the listserve below: http://lists.openfabrics.org/mailman/listinfo/ofiwg-mpi -- Jeff Squyres jsquyres(a)cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
