Meeting reminder: Jul 09, 2020 (today)
by Marc-André Hermanns 09 Jul '20

09 Jul '20

Dear all, @John D.: We will continue to focus on the Erratas for MPI 4.0, so we will not discuss handles again. I will reach out to you again directly when we start discussing handles, OK? This is a reminder of our regularly scheduled call today: Jul 09 at 8 am Pacific / 11 am Eastern / 5pm CET. Webex Info: https://github.com/mpiwg-tools/mpi-standard/wiki *NOTE*: The WebEx information moved to a non-public wiki. You have to be logged into Github *and* have to have access to the private Tools WG repositories. If you need access contact me. Agenda: ------- - Quit feedback on #160/PR#161 discussion with sessions WG. - Ticket #268/PR#168: Completely rethink what is to be said. Potentially eliminate everything before "e.g." - QMPI (if time permits) For PR#161, the discussion took quite an interesting turn (please check my comment on the PR) and I will schedule a separate meeting for that to ensure more people can join. PR#161: https://github.com/mpi-forum/mpi-standard/pull/161 PR@168: https://github.com/mpi-forum/mpi-standard/pull/168 Cheers, Marc-Andre -- Dr. rer. nat.

Binding of predefined handles
by Marc-André Hermanns 08 Jul '20

08 Jul '20

Dear all, Howard, Dan, and I discussed the binding problem on Monday during the sessions WG time slot (thanks again for the time and input) and we came to quite a change in direction this errata is going. We were discussing what was available when for predefined handles (contemplating what *link-time constant* means) and live-testing a bit with Open-MPI. Result was that a test with MPI_Comm comm = MPI_COMM_WORLD; MPI_Init(...); MPI_Send(..., comm); works as we would expect from a link-time constant, in that the value (of the handle, not necessarily the object behind it) is known to MPI before Init and does not change. That gave rise to the question, "If that is possible, what prevents the implementation of 'lazy binding' for an MPI libary?" So this would be a question to all implementors on the list. I updated the Errata with a new suggested text (now actually allowing binding to predefined handles at any time between MPI_T initialization and finalization, as a start for discussing this thoroughly before September. https://github.com/mpi-forum/mpi-standard/pull/161/files#diff-f6fa82f9df45c… The core idea here is that, as a library should always be able to tell apart a predefined handle from a user-defined one, it could catch any binding and postpone it until the handle is initialized.
