May 6 Exceptional Virtual Meeting Registration
by Wesley Bland 22 Apr '20

22 Apr '20

*** ACTION ITEMS *** 1. Register for the May 6 Exceptional Virtual Meeting 2. Read the procedure changes proposal to enable virtual meetings 3. Attend the May 6 Exceptional Virtual Meeting and vote on the proposed changes *** Hi folks, As we’ve been discussing for the last few weeks, the MPI Forum will need to adapt to the current global situation. Specifically, because most of us are unable to travel, we will need to hold at least our planned June meeting and possibly future meetings as virtual meetings rather than physical meetings. To that end, I’ve drafted new rules to support this change, and we’ve all been discussing them during the recent virtual meeting time slots. After our meeting earlier today, I think we’ve reached agreement on how these rules should look and they are ready to be put up for a vote. You can find the proposed rule changes on the pull request here: https://github.com/mpi-forum/procedures/pull/5 <https://github.com/mpi-forum/procedures/pull/5> If you get a 404 error trying to view that page, it’s either because you’re not logged into GitHub or because you don’t have access to the repository. You can email me directly to get access. To vote in these new rules, because we don’t have any existing rules to do so, we’ll use the new rules themselves. To that end, we will hold our first Exceptional Virtual MPI Forum Meeting in two weeks, on May 6, 2020. The meeting will happen in our usual virtual meeting time slot (10 AM US Central time). You can find all of the information in the usual place for a voting meeting (used to be called physical): https://www.mpi-forum.org/meetings/ <https://www.mpi-forum.org/meetings/> During that meeting, I will officially read the proposed changes to the procedures. After that, I’ll open up the voting system for everyone who attends. In order to run this meeting as close to our existing rules as possible and enable us to calculate quorum, everyone will need to register (for free) for the meeting before the meeting time at the following link: https://forms.gle/jJxi5ztuoYg6xGSk8 <https://forms.gle/jJxi5ztuoYg6xGSk8> Note that if you do not register, I will not email you the link to vote. Also, this meeting will use the same rules for quorum as any other MPI Forum meeting so it is important that each organization register at least one person. Because we are calling this meeting on relatively short notice, I plan to leave the voting site running for 24 hours to give people who can not attend the ability to vote at a time that is more convenient for them. If you can not attend the call during the usual time slot, please make sure you read the proposal carefully and/or watch the recording of today’s call (posted on the virtual meeting website tomorrow) to hear the unofficial reading. Please let me know if you have any questions. Thanks, Wes

MPI Pythonization has been merged
by William Gropp 15 Apr '20

15 Apr '20

I have merged the pythonization PR into mpi-4.x . If you have a pending pull request, please review and address any conflicts or issues. I will be working on the formatting issues that Rolf has found, but those should not affect anyone (they will be changes to the macro definitions only).

Editor Changes for the Virtual Meeting Tomorrow
by Wesley Bland 14 Apr '20

14 Apr '20

Hi all, I just wanted remind folks that if you have an editor change that has been assigned to you, please try to finish those as soon as possible. Most are very short and can probably be done quickly. We have 12 that are already done (plus a few more I hope to do this afternoon). We’ll discuss these during the Virtual Meeting on Wednesday at 10:00am US Central time <https://time.is/1000AM_15_April_2020_in_Chicago>. I’m keeping track of the status of all of these issues here: https://github.com/mpi-forum/mpi-issues/projects/1 <https://github.com/mpi-forum/mpi-issues/projects/1> The issues we still need to discuss are in the “To Be Classified” column. We’ll talk about those (time permitting) on Wednesday after the Sessions discussion. The issues that have been scoped and assigned to someone are in the “Awaiting Implementation” column. If you have something in that column, you can go ahead and work on it and create a pull request. When you do that, I’ll see it and update the board. Please make sure that when you do, you reference the original issue in the PR description saying: Fixes mpi-forum/mpi-issues#1234 This is the best way to make sure the automatic links are created. If you try to do the links manually by doing something like using Markdown to make the links [like this](https://github.com/mpi-forum/mpi-issues/issues/1234 <https://github.com/mpi-forum/mpi-issues/issues/1234>), then the link doesn’t work properly. The issues that have open pull requests implementing them and are ready for discussion are in “Awaiting Informal Reading”. My plan is to clear out this column each Wednesday during the virtual meeting. If you have something in this column, please plan to attend the call on Wednesday to read your PR. For this week so far, that includes: * Guillaume * George * Thomas * Wesley / Aurelien * Joseph The last column, “Finished Informal Reading" is for the issues that have already been implemented and read. So far, that includes things that were done by the Pythonization branch, but I’ll move things over there as we work through the issues. Thanks to all for helping to clear this backlog. If you’re willing to contribute by helping with one of these issues, there are a number of issues assigned to the document editor (Bill) (https://github.com/mpi-forum/mpi-issues/projects/1?card_filter_query=assign… <https://github.com/mpi-forum/mpi-issues/projects/1?card_filter_query=assign…>) that could be picked up by anyone. Some probably require his expertise, but I’d be happy to point you toward some easy ones. You can also talk to the chapter committee chair of your favorite chapter and I’m sure they’d be happy to share the workload. Thanks and talk to you Wednesday, Wes

Q2 2020 PMIx Standard Quarterly Administrative Steering Committee (ASC) Meeting
by Mohror, Kathryn 08 Apr '20

08 Apr '20

Hello everyone, The PMIx community is pleased to announce the second-quarter meeting of the Administrative Steering Committee (ASC) of the PMIx standardization body for 2020. The objective of the PMIx standard is to provide an implementation-independent specification to facilitate interaction between applications, tools, and middleware and system runtime environments. The interface focuses on supporting application launch and wire-up; supporting tools that wish to inspect, steer, and/or debug parallel applications; providing interfaces to manage dynamic workload applications, to support fault tolerance and cross-library coordination; and facilitate communication across container boundaries. The PMIx standard is governed by the ASC comprised of representatives from a wide range of research, academic, and industrial organizations. The ASC plays a critical role in shaping the evolution of this critical system interface. The goal of this meeting is to read, discuss, and vote on modifications to the PMIx standard, discuss potential modifications or new ideas for the standard, welcome formal participation in the governance body from new, interested groups, and learn of community progress with respect to PMIx. As such we are calling for broad participation from the parallel and distributed computing community to participate in this meeting. Meeting information: * Date: April 15, 2020 * Time: 11 am - 5 pm US Central Time * Location: Virtual (online) Meeting (see agenda link for details) * Meeting Link: https://github.com/pmix/pmix-standard/wiki/ASC-Q2-2020-Meeting For more information about the PMIx standardization body and its activities please join the mailing list [1], check out the activity on the GitHub repository [2], and/or review the website [3].

Re: [Mpi-forum] Reminder: Next Virtual MPI Forum Meeting: Wednesday 10am US Central Time
by Martin Schulz 02 Apr '20

02 Apr '20

Hi all, Just as a reminder and addendum to Wesley’s email, in particular if you had to drop off early yesterday or couldn’t make it: As Wesley said, we went through issues 161-181 yesterday, which means we covered the classification and we assigned unassigned tickets; in cases where there was no volunteer or obvious victim, we assigned it to the chapter or working group chair matching the topic. In these cases, you should have gotten email through GitHub alerting you of that - please check. Next week, we will first circle back to the assigned tickets 161-181 to see if a suggested change or wording is ready - especially for non ticket 0 or chapter committee changes - and discuss them. Hence, if you have a ticket assigned, please try to complete it by next Wednesday (they are typically very small items). After that, we will continue with 182++ for next assignments. Thanks! Martin PS: As a reminder - we will continue with this process unless we get requests for other topics that need to be discussed in our virtual meetings as part of the MPI 4.0 finalization. If you have one of these items, please let Wesley and me know (preferably substantially ahead of the meeting time you would like to request).

As a reminder, we’re always looking for folks to pick up a few GitHub issues. We’ve already covered everything from #161 to #181 in the call today. Next week we’ll cover some more. Feel free to grab anything that’s already unassigned before #181 and present a short pull request next week to resolve it. If you don’t know what to do, but want to help, no problem!

Updated Proposal for Virtual Meeting Procedures
by Wesley Bland 01 Apr '20

01 Apr '20

Hi all, Based on the feedback during today’s virtual meeting, I’ve updated the proposal to include text about how to change the procedures document without a physical meeting. https://github.com/mpi-forum/procedures/pull/5 <https://github.com/mpi-forum/procedures/pull/5> As we said during the call, this obviously won’t apply for the current situation since we don’t currently have any rules to cover the situation we’re in, but if we ever need to update the procedures document again under extraordinary circumstances, we’ll now have documented what we did this time. As part of the rules, I specified a two week timeline (as with all other voting announcements) between showing the text and reading/voting. So this email will serve as the two week announcement. Next Wednesday I’ll present the text again for comment and we’ll vote on it the following week. Thanks, Wes
