September MPI Forum Reading and Vote Announcments
by Wes Bland 22 Aug '22

22 Aug '22

Hi all, I think Martin may still be out on holiday, so on his behalf I wanted to remind folks about a few things coming up: 1. We have virtual meetings for the next two weeks. This week, Joseph will lead a discussion about RMA topics that are planned for a reading at the September meeting. Next week, Ignacio will lead a discussion of the Reinit fault tolerance proposal. Please attend and give early feedback if possible. Recordings will be posted in the usual place on the website (https://www.mpi-forum.org/virtual_meetings/ <https://www.mpi-forum.org/virtual_meetings/>) after the meeting is over. 2. Please continue to work on the outstanding issues for MPI 4.1 that are assigned to you: https://github.com/orgs/mpi-forum/projects/1/views/3 <https://github.com/orgs/mpi-forum/projects/1/views/3>. As discussed during the VM, we’re trying to get through as many of these as possible to be able to turn out MPI 4.1 in the early timeframe. 3. Along those lines, if you have made progress on your MPI 4.1 issues (or anything else), go ahead and start sending out announcements to this list for the September 2022 meeting. The announcement deadline is September 12, but early announcements are always welcome. Remember that the upcoming meeting will take place as a hybrid meeting with both in-person attendees in Chattanooga, TN and remote participation via Zoom. We’re working with our new SPI partners to get the registration page set up for both the conference and the MPI Forum meeting as quickly as possible and will post details as soon as it’s ready to go. We’ll also post a more specific schedule when we have it, but we’ll be running this meeting as we have run in-person meetings in the past with full-day meetings in the local time zone. Thanks, Wes

Virtual MPI Forum Meeting Tomorrow (ACTION ITEMS INCLUDED)
by Martin Schulz 19 Jul '22

19 Jul '22

Hi all, After some break, we’ll have an MPI Forum Virtual Meeting tomorrow at the usual time – 10am CT – and using the usual link, which is on github at the usual place. As mentioned before, the goal tomorrow is get an overview of the state in the various working groups and chapter committees in our progress to MPI 4.1. We will use this to build a todo/gating issues list during the September meeting and with that plan a (hopefully) concrete timeline for MPI 4.1. However, this means that we need your input on two things: The status of the open items on the github boards (see Wesley’s email from July 6th) Any open issues from the WGs that should be considered for MPI 4.1 (or which ones can be postponed to MPI 5.0) (keep in mind, though, MPI 4.1 was not supposed to include major items or additions, just cleanup and minor urgent changes) Therefore, I would like to ask all of to review these items above (especially if you are tagged on one of the items on the github boards). Also, it would be really helpful, if each WG lead would be able to join us tomorrow or have a representative, so we can discuss the open issues. For reference, here are the links to the boards: * https://github.com/mpi-forum/mpi-issues/projects/3 (GitHub’s old project boards version) * https://github.com/orgs/mpi-forum/projects/1/views/2 (GitHub’s new project boards version) Thanks and hopefully see/hear you all tomorrow, 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

Re: [Mpi-forum] MPI 4.1 Plans and Progress
by Jeff Hammond 06 Jul '22

This conflicts with the Fortran WG5 meeting, although I guess I’m on the only affected person, since Bill Long doesn’t appear to have any outstanding issues with MPI right now. https://github.com/mpi-forum/mpi-issues/issues/17 <https://github.com/mpi-forum/mpi-issues/issues/17> is a good one for 4.1, since it is merely a clarification. I took care of some of the work, but have no time to work on the LaTeX changes to implement it. I’ve asked the RMA WG to make forward progress on https://github.com/mpi-forum/mpi-issues/issues/23 <https://github.com/mpi-forum/mpi-issues/issues/23>, which is one of a handful of issues that are reasonable to do in 4.1. While I like to be active in the discussion, I no longer have the ability to work on the LaTeX document, particularly since everything about it has changed since I last edited it, and because I no longer use LaTeX regularly (sob #CorporateLife).

MPI 4.1 Plans and Progress
by Wes Bland 06 Jul '22

06 Jul '22

Hi all, We’re going to discuss this at a virtual meeting on July 20th, but as there is some potential pre-work for the owners of these issues, I wanted to give people a preview so they could get started early. As discussed during the run up to MPI 4.0, we intend MPI 4.1 to be a (relatively) quick update to the MPI Standard to fix more minor issues with unclear semantics, terms, general formatting, etc. This release is not intended to include a large number of new features (though there will of course be some). During MPI 4.0, we started using the GitHub Projects features to keep track of how our work was progressing and to understand what our targets were. We also made boards for MPI 4.1 and MPI 5.0. I’d like to draw your attention to the MPI 4.1 project board for the discussion in a few weeks. Both of the boards show the same data. They just use different layouts. Feel free to look at whichever you like best. * https://github.com/mpi-forum/mpi-issues/projects/3 <https://github.com/mpi-forum/mpi-issues/projects/3> (GitHub’s old project boards version) * https://github.com/orgs/mpi-forum/projects/1/views/2 <https://github.com/orgs/mpi-forum/projects/1/views/2> (GitHub’s new project boards version) I want to point out that we currently have 148 open issues marked for MPI 4.1, which means there is a lot of work that we hope to have done in the next year or so in order to release MPI 4.1. Each of these items has an owner that should be responsible for moving the issue forward.

FEEDBACK REQUESTED: Upcoming MPI Forum Meetings
by Martin Schulz 28 May '22

28 May '22

Hi all, At the end of the forum meeting we also had an initial discussion on how to proceed with the MPI Forum meeting series, now that the pandemic is at least (hopefully) nearing its end. First, the next meeting will be 9/28-9/30 and it will be held as a hybrid meeting, i.e., both online and in person after EuroMPI in Chattanooga – following our rules, this will again be an “exceptional virtual voting meeting”, i.e., the same rules will apply as for the fully virtual meeting this week. What will change, though, is that we will follow a timing for the sessions that matches the local setup. However, we do know that this will create issues for folks joining from other timezones and we will take this into account. As for the following meetings: there seemed to be a consensus that our normal cadence of 4 voting meetings per year is still appropriate (please speak up if you disagree). Following our usual timeline, the following dates/weeks could work: Winter 2022: December 5-8, 2022 Spring 2023: February 27-March 2, 2023 Summer 2023: May 29-June 1, 2023 Fall 2023: together with EuroMPI in September (Dates tbd.) Note, this are just proposals! Please check if there are any substantial conflicts – we will adjust the dates if there are such and we will send a final proposal for dates before deciding on final dates. However, please send possible conflicts rather sooner than later, to give us time to react. Third, we had a discussion on whether to return to all or part in Person meetings – both for the tail end of the pandemic, but also afterwards. The general consensus from the attendees this week was that we need some in person meetings again (1-2 per year), but neither fully virtual nor fully only in person are good options. Also, there was a strong push towards allowing hybrid participation of some sort, possibly coupled with different voting roles. However, it was also clear that hybrid meetings will cause technical challenges. As a consequence, we decided to wait out the first hybrid meeting in September and then decide on how to proceed after that. The December meeting will be virtual for sure, with a possible hybrid option for the Spring meeting. If we do want to go hybrid for the spring, though, we would need volunteers that could host us in their organization and that have good video conference setups (similar to what we had at Cisco or Microsoft) in order to support such a meeting. If you are interested and willing to host the MPI forum (for the spring meeting or also in general), please let Wesley and me know. I think this covers the discussion at the forum meeting – if I missed something, or if you were not able to attend the discussion this week and would like to comment, please follow up here. Thanks!
