Hello All, The Fault Tolerance and Error Handling WG would like to bring to a vote the first part of fine-grain fault tolerance: process failure error semantics and revoke (aka ulfm part 1). Issue: https://github.com/mpi-forum/mpi-issues/issues/581 PR: https://github.com/mpi-forum/mpi-standard/pull/665 This has been read during the Sept. 22 meeting and is brought forward without changes.

Reading request for Session WG issue related to clarifying err handling fallback
by Aurelien Bouteiller 21 Nov '22

21 Nov '22

Hello All, I’d like to put in a request to read the following pull request at the December ’22 MPI Forum: ## Clarification of errhandler fallback with Sessions Issue: https://github.com/mpi-forum/mpi-issues/issues/588 PR: https://github.com/mpi-forum/mpi-standard/pull/644 PR 644 was already read (as-is) in prior meetings, but it was labeled under the wrong issue number and that caused confusion. In the spirit of transparency we will restart the process with a dedicated issue number. This is an MPI 4.1 item.
