Dear MPI forum members,
at the virtual meeting this week (June 14, 2023) on "Any Pending Items for MPI 4.1" (Martin)
I would like to re-read the following proposals:
#710/PR823 clarifying MPI_COMM_DISCONNECT, MPI_FINALIZE and MPI_SESSION_FINALIZE
with an additional option about inactive persistent requests within a session, and
#676/PR825 resolving the missing definition of pending communication operation
in a hopefully understandable and easy way.
Details:
__________________________
#710 Errata: 'Pending communication' not defined in MPI_Comm_disconnect Rolf
Issue https://github.com/mpi-forum/mpi-issues/issues/710
PR https://github.com/mpi-forum/mpi-standard/pull/823
PDF https://github.com/mpi-forum/mpi-standard/files/11739843/mpi41-report_Issue710_PR823_update5_for-2023-6-14-meeting.pdf
This proposal clarifies MPI_COMM_DISCONNECT, MPI_FINALIZE and MPI_SESSION_FINALIZE
with an additional option about inactive persistent requests within a session.
__________________________
#676 Errata: 'Pending operation' not defined, pending proper definition Rolf,Joseph
Issue https://github.com/mpi-forum/mpi-issues/issues/676
PR https://github.com/mpi-forum/mpi-standard/pull/825
PDF https://github.com/mpi-forum/mpi-standard/files/11732752/mpi41-report_Issue676_PR825_v3.pdf
Defining "pending operation" as "active operation" (see page 12)
Best regards
Rolf

>>
>> If I have overseen something, then my apologies.

>> - Thanks to Joseph who did PR 822, which was such a counter proposal for #705.
>> - This method is often better than doing many change requests for the given PR.
>> and it helps to completely check whether it is really consistent over
>> all related parts of the MPI standard.
>> - And thanks for all the comments so far. They really helped me a lot for
