Why is such a proposal coming out of the hybrid working group ? This is more appropriate for the point-to-point working group. Not that it is that critical what the group name is, but more to get feedback from a wide range of folks interested is such topics. Rich From: mpi-forum [mailto:[email protected]] On Behalf Of Jim Dinan Sent: Saturday, November 22, 2014 8:58 AM To: Main MPI Forum mailing list Subject: [Mpi-forum] Info Keys Ticket Hi All, The hybrid working group would like to put forward ticket #461 (https://svn.mpi-forum.org/trac/mpi-forum-web/ticket/461) for consideration for MPI 3.1, with a formal reading at the upcoming December meeting. This ticket proposes the no_any_tag and no_any_source info keys, on which we have achieved consensus. We continue to have vigorous and productive debate on additional communicator info keys proposals that have been captured in #381. We will pursue these additional proposals for MPI 4.0. Thanks and see you in December, ~Jim.
