Item for discussion at 7/31/23 Sessions WG meeting
by Pritchard Jr., Howard 25 Jul '23

25 Jul '23

HI All, I opened an issue to track the “datatype” problem we have at the moment in the 4.1 standard – https://github.com/mpi-forum/mpi-issues/issues/733 We can discuss ideas on how to handle this on Monday. I’ll be out the rest of this week but will be back on Monday.

by Pritchard Jr., Howard 23 Jul '23

23 Jul '23

Hi All, There were no particular topics suggested for discussion if we meet on 8/24/23, so canceling. I will try to get an issue opened about the datatype problem that we can discuss on 8/31.

Topics for Sessions WG meeting 7/24/23
by Pritchard Jr., Howard 20 Jul '23

20 Jul '23

Hi All, Let me know if you have topics to discuss for the next scheduled sessions WG meeting on 7/24/23. I’m not sure if we have more to discuss on https://github.com/mpi-forum/mpi-issues/issues/732 ? I’ve updated the issue with observations about Open MPI’s behavior here and Hui clarified which MPI implementation actually did hang when an app had failed to free a persistent request. I’ve not had a chance to open an issue about the datatype handles we discussed when covering some of the changes accepted by the forum for https://github.com/mpi-forum/mpi-issues/issues/710<https://urldefense.com/v3/__https:/github.com/mpi-forum/mpi-issues/issues/7…> . I hope to have that done before our 7/31/23 meeting.

Sessions WG - meet on Monday at 9 AM US CDT
by Pritchard Jr., Howard 14 Jul '23

14 Jul '23

Hi All, We’ll discuss some of the items that came up/voted in a the last MPI Forum. In particular, there’s more discussion going on and is being tracked by https://github.com/mpi-forum/mpi-issues/issues/732 We will also discuss https://github.com/mpi-forum/mpi-issues/issues/710 and associated PR. Note the zoom link at https://github.com/mpiwg-sessions/mpi-standard/wiki still works for the new meeting time of 9 AM US CDT, but the zoom invite has not been updated (as best I can tell).

HI Dan, I think Martin Schulz owns the zoom account. Martin could you send out an updated invite for the new time?

Hi Howard, I keep getting the time wrong because I've not updated the calendar entry, although my absence today is more because I took your "I’m leaning toward cancelling" rather more literally than you meant it. The "ics" file on the wiki page (https://github.com/mpiwg-sessions/mpi-standard/wiki) gives the error "contains no appointments". Did we get confirmation from the owner of the Zoom account that it was okay to move the meeting time permanently?
