Reading + No-no-vote #669 at MPI-Forum meeting Feb 1+8, 2023 (related to Terms)
by Rolf Rabenseifner 31 Jan '23

31 Jan '23

Dear MPI forum members, dear Wesley, based on the results of the virtual forum meeting on "terms" on Jan 25, 2023, and helpful and productive discussions with Dan Holmes, I implemented the results. The modified wording does not change the major goal of the ticket: adding the new term 'enabled' to describe the relation between semantically-related operations in different processes. The other topic, the extension of the terms local and nonlocal also to invocations under constraints was not changed. Therefore reading and an additional no-no-vote is needed.

Reading + No-no-vote #543 at MPI-Forum meeting Feb 1+8, 2023 (related to Terms and Contexts)

Dear MPI forum members, dear Wesley, based on the results of the virtual forum meeting on "terms" on Jan 25, 2023, I implemented the results. This is a shortening in modified wording, but no change in the major goal of the ticket: solving the problem that "pending operations" is not a defined term.

March 2023 Meeting Straw Poll
by Wes Bland 19 Jan '23

19 Jan '23

Hi folks, In an attempt to help Quincy with planning and ourselves with pricing for the March meeting, it would be helpful to get a ballpark figure of how many people plan to come to the meeting. We’re aware that many companies have travel restrictions right now, and some people will choose not to travel for other reasons. We’re not ready to open registration yet (since we don’t know how much to charge), so if people could help us by indicating whether they plan to attend the meeting in-person, that would be very useful. Please fill out the quick two question survey below to help us out. https://forms.gle/BHiUDkeSJqDptpcK8 2023 March Meeting Attendance forms.gle Thanks, Wes

Hello all, The Fault Tolerance and Error Handling WG would like to bring for a reading text adding the procedures to remove user-defined error classes, codes, and strings.
