Hi all, Tony just asked a good question off list about how to do the diff from December, but I think others will find this useful so I wanted to put it on the list: It’s up to each person, but if I were doing it (which I guess I am 😀), I would start with the diff and see if it needs to be summarized beyond that. Here’s a link to the online version of the diff: https://github.com/mpi-forum/mpi-standard/compare/mpi-4.0-rc-dec-2020...mpi-... <https://github.com/mpi-forum/mpi-standard/compare/mpi-4.0-rc-dec-2020...mpi-4.0-rc-june-2021> You can click on “60 changed files” at the top of the diff and pick just the file you want from there. You can also get the same thing on the command line by fetching all of the remote tags and doing the comparison there (example with just the I/O chapter): $ git fetch —all —tags $ git diff mpi-4.0-rc-dec-2020 mpi-4.0-rc-june-2021 chap-io/io.tex Thanks, Wes

Hi all,

This is a bit of a long one with all of the announcements for the upcoming meeting, so stick with me:

The RC document for the June meeting is now available on the website. You can find it here: https://www.mpi-forum.org/docs/mpi-4.0/mpi40-rc-jun-21.pdf <https://www.mpi-forum.org/docs/mpi-4.0/mpi40-rc-jun-21.pdf>

I’ve also posted all of the plenaries and votes for this meeting that come from the ratification process. I’ll read each of these in the same way we did the last meeting to move things along more quickly. Today also closes the nomination period for officers. We’ll vote for those in the upcoming meeting.

Reminder to Chapter Chairs: As we’ve discussed previously, we’ll do a recap of the changes that have happened to each chapter since December 2020. Please have a slide or two ready to go over those changes..

You can find all of that on the agenda page: https://www.mpi-forum.org/meetings/2021/06/agenda <https://www.mpi-forum.org/meetings/2021/06/agenda>

Here’s that list: Procedure

If you have any other plenaries/votes to announce, please do so today. Martin will be updating the agenda later to include everything for the meeting. Note that we’ll need to have a voting block every day in order to accommodate our voting rules for a Final Ratification Meeting

Thanks, Wes
