reading announcement: PR 958 (ABI)
by Jeff Hammond 29 Feb '24

29 Feb '24

https://urldefense.us/v3/__https://github.com/mpi-forum/mpi-standard/pull/9… is not the final version but will be final on Sunday. This fixes most of the prior complaints and adds what can be added about Fortran. However, a full standard ABI for Fortran is not included because it's not practical at this time.

March 2024 MPI Forum Registration
by Wes Bland 06 Feb '24

06 Feb '24

Hi all, The registration page for the March MPI Forum meeting is now live. https://www.eventbrite.com/e/mpi-forum-march-2024-meeting-tickets-823784901… Regardless of whether you are attending in-person or remotely, please fill out the registration form. If you are attending remotely, there is a free ticket. If you are attending in-person, the ticket will be $150 + Eventbrite fees (about $11 in the US). Please register ASAP so I can plan some of the logistics on the hosting side. One difference for this meeting is that we will be eating in the building cafeteria rather than having catered meals. Looking at the menu’s for the current week’s meals as an example, it looks like there are options for all of the dietary restrictions and preferences that I’m aware of in the past (e.g., non-dairy, vegetarian, gluten free, etc.) and everything is well labeled. If you have any concerns, please let me know and I can look out for something in particular. Thanks, Wes

Dear all, For planning purposes, I'd like to request some plenary time for the following items: - A proposal on process time synchronization: https://github.com/mpi-forum/mpi-issues/issues/829 - A proposal on immediate request completion: https://github.com/mpi-forum/mpi-issues/issues/828 - Hyperrefs for symbols in the document: https://github.com/mpi-forum/mpi-issues/issues/826 - Related: incorrect usage of MPI macros: https://github.com/mpi-forum/mpi-issues/issues/825 - MPI continuations (no official ticket yet) - A discussion on what guarantees users can expect of MPI_Status elements: - Outcome of MPI_Test_cancelled on nonblocking collective requests not defined: https://github.com/mpi-forum/mpi-issues/issues/821 - Content of status not defined for partitioned requests: https://github.com/mpi-forum/mpi-issues/issues/820 - Whether to always set MPI_ERROR in MPI_Status: https://github.com/mpi-forum/mpi-issues/issues/814 None of these are official readings so they can be scheduled at any time and if we don't make it through all of them that's fine too. I don't want to occupy the full week :) See you Chicago, Joseph

March Meeting / Agenda Requests and New Location
by Martin Schulz 03 Feb '24

03 Feb '24

Hi all, Our March Meeting, which will be hybrid, is slowly coming up – we are scheduled for March 18-22 in Chicago. However, there has been a change in venue: the meeting will be hosted by Meta (thanks, Wes!). The new venue is still downtown Chicago, so hopefully this change will have no negative effect for anyone. The logistics page with exact location information is up and we will add a registration page soon (as soon we have exact cost estimates). In the meantime, please let me know if there are any additions to the plenary sessions and – for now more important – if any WG would like to use the meeting for dedicated WG time. For now, I have reserved the two sessions for WG time (one on Monday and one on Tuesday), but we can adjust as needed. Thanks!
