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!

Martin
