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.
