Reading Announcements Buffer Send Handling
by Martin Schulz 26 Feb '23

26 Feb '23

Hi all, Adding to Rolf’s previous announcement of the reading of Issue 586 (MPI_Buffer_attach and Sessions): The issue/PR has been updated to reflect the discussion from last time Zero buffer size behavior is now the same as in MPI 4.0 Automatic buffering is enabled by using a constant for the buffer argument Small text updates No changes in default behavior Further, there are now two companion issues with PRs, which I would like to read as well: Issue 684: make the automatic buffering the default behavior Issue 685: adds iflush procedures Note: the PRs for those two issue contain all changes for 586 as well and will have to properly merged should they pass. Also, should 586 fail, these issues will be retracted. Thanks!

Reading announcement for the 2023 March meeting of the MPI Forum
by Julien.JAEGER＠CEA.FR 24 Feb '23

24 Feb '23

Dear all, in addition to my previous announcemens, I would like to read the following : - issue: https://github.com/mpi-forum/mpi-issues/issues/341 (RC issues found in chap-coll) - PR: https://github.com/mpi-forum/mpi-standard/pull/806 (Fix most issues in collective chapter from MPI4.0-RC) This PR handles: - Process -> MPI process - root process/process root/etc... -> the root / the root is clearly defined in the chapter introduction - data type -> datatype - using \mpiarg{} and \mpicode{} when appropriate - and multiple small corrections that are identified by ticked boxes and the comment gathering other handled suggestions which had no box to tick in https://github.com/mpi-forum/mpi-issues/issues/341 Note that I sorted all suggestions in this issue in four separate comments: - suggestions handled in this PR https://github.com/mpi-forum/mpi-standard/pull/806 - suggestions that were already handled in other PRs and are corrected in the current mpi-4.x branch - suggestions that are not relevant, or that will be isolated in their own private issue - suggestions that are not handled yet and still need to be dealt with. If the current PR passes the reading, I will create a new issue with only the remaining suggestions. I updated all pages and lines references in the suggestions. In my comment, pages and lines now refer to the official MPI-4.0 standard (much more easy to find the issue). Best regards, Julien J.
