Hi everyone, We have a meeting scheduled for today. It may be short, as the agenda for next week Forum Meeting is locked. I have announced the following readings for the Forum Meeting next week. * expansion of error handler association to cover sessions (and clarifications) * https://github.com/mpi-forum/mpi-standard/pull/644 * fine-grain recovery (slice 1) (aka ULFM v2) * https://github.com/mpi-forum/mpi-standard/pull/665 We’ll make a roundtable call to see if someone wants to add an agenda item.

Meeting Summary ===============

Advice about unsupported fault types ------------------------------------

We discussed changes to the introduction of fine-grain recovery to add an advice to implementors about non-process-fail-stop faults. Text visible here:

https://github.com/mpiwg-ft/mpi-standard/pull/17

Overall text appears clear enough, please add more feedback on the PR itself (ping me if you do not have access to the repo).
