Reply-To: Main MPI Forum mailing list <mpi-forum(a)lists.mpi-forum.org<mailto:[email protected]>> Hi all, Just as a reminder, today (i.e., THIS Wednesday) we will have our next virtual meeting in this quarter. The webex information can be reached via https://www.mpi-forum.org/meetings/ The topic will be a discussion on how we want to proceed with the MPI standard in general, what our roadmap is and how much we want to stick to backwards compatibility. This topic come out of a discussion towards the end of the MPI Forum in Barcelona and was triggered on how to handle “BigCount”, but then quickly went much wider. We ended up with a large majority (of those present only, of course) wanting to investigate this further and possible opting for something we called a “fork” of the standard, i.e., having an MPI 3.x line and an MPI 4.x line, which would no longer be backwards compatible, but still composable. The meeting today is intended to be an open discussion to a) continue the discussion from Barcelona and to b) get the pulse from people who were not at the meeting.
