No MPI Virtual Meeting Today / Plans for next weeks
by Martin Schulz 26 May '21

26 May '21

Hi all, We'll have no virtual MPI forum meeting today. Next week, we'll also skip a general meeting, but instead Rolf would like to get an extended MPI Terms WG together (focus on the progress rules, with all interested parties and specifically the RMA WG). We'll use the usual time slot and the usual link for this. The following week, we'll then have the MPI forum meeting - the concrete agenda is online and we'll meet 9:00-1:00 US Central Time on Mo-We (hopefully three days are sufficient this time). If anything is missing from the agenda, please let Wesley and me know. Thanks!

Re: [Mpi-forum] June 2021 Voting Announcements and RC Document

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…> 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 > On May 24, 2021, at 11:30 AM, Wesley Bland <work(a)wesbland.com> wrote: > > 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.
