Doodle poll for new time options for Sessions WG meetings (still on Mondays)
by Pritchard Jr., Howard 07 Jun '23

07 Jun '23

HI Folks, Per discussions at the last Sessions WG meeting about moving to an earlier time in the day for our regular meetings, I’ve hopefully created a doodle poll we can use to pick a time. https://doodle.com/meeting/participate/id/dLvMNLXa Times are all earlier than the current 12 PM US central time in recognition of the fact that typically at least half of the participants on the calls are from UK or central European time zones. I’ll ask Martin Schulz to adjust the zoom meeting once we’ve settled on a new time. We will stick with the current 12 PM US central time if we meet next Monday.

Sessions WG - request for topics for 6/5/23 meeting
by Pritchard Jr., Howard 01 Jun '23

01 Jun '23

HI All, If you have a topic you’d like to discuss at next weeks Sessions WG meeting let me know and I’ll put it on the agenda. I’ve got one item to discuss, namely rewording of Sessions related functionality to lift some restrictions that currently exist on allowed pset name arguments to MPI_Group_from_session_pset. I’ve started work on a branch where these sorts of changes will be made. See https://github.com/hppritcha/mpi-standard/commit/b637545dc5f0c47ca897d5b8ce… Thanks, Howard — [signature_61897647] Howard Pritchard Research Scientist HPC-ENV Los Alamos National Laboratory howardp(a)lanl.gov [signature_2141780240]<https://www.instagram.com/losalamosnatlab/>[signature_2668660589]<https://twitter.com/LosAlamosNatLab>[signature_3191167880]<https://www.linkedin.com/company/los-alamos-national-laboratory/>[signature_432265969]<https://www.facebook.com/LosAlamosNationalLab/>

Sessions WG meeting 5/29
by Pritchard Jr., Howard 25 May '23

25 May '23

Hello All, This coming Monday is a US holiday so many of the US folks will be taking the day off. So I propose canceling next Monday’s Sessions WG meeting. For the following Monday, 6/5, I’d like to discuss this small change to the standard https://github.com/hppritcha/mpi-standard/commit/b637545dc5f0c47ca897d5b8ce… Its small but gives us an out for some of the dynamic pset work some of us are exploring.

Re: [mpiwg-sessions] Agenda items for Sessions WG meeting - 5/8/23

Hi Howard (et al), I wrote down my thoughts on #710 (including the sessions viewpoint) here: https://github.com/mpi-forum/mpi-issues/issues/710#issuecomment-1536306552 Addendum, just for sessions folks: ``` C MPI_Init(); MPI_Recv_init(..., MPI_COMM_WORLD, &req); MPI_Finalize(); MPI_Request_free(&req); // erroneous, MPI is no longer initialised, so calling MPI_Request_free is prohibited MPI_Session_init(); MPI_Request_free(&req); // oh dear lord, what is this? Surely this is also erroneous, but where ...flicks through the MPI Standard... is the prohibition in the standard? MPI_Session_finalize(); ``` Best wishes, Dan.
