MPI Voting Meeting Feb 28-Mar 3 2022 (next week)
by Martin Schulz 22 Feb '22

22 Feb '22

Hi all, I have added the agenda for next week’s meeting onto the MPI forum website at: https://www.mpi-forum.org/meetings/2022/02/agenda If I forgot any issues/ballots/items, please let me know. It seems, though, that we actually have a very light plenary agenda. On the other hand, we have currently some quite active WGs. Therefore, I am proposing to go back to the format from before corona and before the MPI 4.0 push, where we mixed longer blocks for working groups and plenary times. We will meet at the usual times, as the last few voting meetings – 9am to 1pm US CT – but Monday and Tuesday are reserved for WGs. Currently, the Sessions WG is scheduled for Monday and the RMA WG for Tuesday, but we can add parallel sessions, if WGs would like to. Please let me know. Wednesday/Thursday is reserved for plenary work – however, as the agenda is light, we could well be done on Wednesday (famous last words) and so I marked Thursday as a backup day for now. Thanks and talk to you all next week, Martin -- Prof. Dr. Martin Schulz, Chair of Computer Architecture and Parallel Systems Department of Informatics, TU-Munich, Boltzmannstraße 3, D-85748 Garching Member of the Board of Directors at the Leibniz Supercomputing Centre (LRZ) Email: schulzm(a)in.tum.de

4.1 reading: allow MPI_*_GET_NAME functions to accept MPI_*_NULL
by Jeff Squyres (jsquyres) 22 Feb '22

22 Feb '22

This is a pretty trivial issue (famous last words), and I have no idea about the current timeline, but it would be nice if this issue could make it into MPI-4.1. Either Howard Pritchard or Joseph Schuchart will read the following at the next meeting where this can be scheduled (this is clearly too late for the Feb 28 meeting, so please add this to the 23 May meeting; thanks): * Issue: https://github.com/mpi-forum/mpi-issues/issues/544 * PR: https://github.com/mpi-forum/mpi-standard/pull/652 -- Jeff Squyres jsquyres(a)cisco.com

Readings on February Meeting
by Marc-André Hermanns 21 Feb '22

21 Feb '22

Dear all, the tools group wants to read two tickets at the next meeting: ----------------------------------------------------- #542: Correct usage of the terms error and return codes in the tools chapter Issue: https://github.com/mpi-forum/mpi-issues/issues/542 PR: https://github.com/mpi-forum/mpi-standard/pull/646 ----------------------------------------------------- #520: Add compound datatypes for large integers for MPI_(MIN|MAX)LOC Issue: https://github.com/mpi-forum/mpi-issues/issues/520 PR: https://github.com/mpi-forum/mpi-standard/pull/648 Please check each individual commit, as these address different problems with the existing list of types for MPI_(MIN|MAX)LOC. ----------------------------------------------------- I would also like to get some plenary time for discussing "extensions or replacements" to #520 and explore a solution for #519, but we don't have PRs ready for a reading and still need preparations for those.
