Am I mistaken in remembering that MPI doesn't allow an application to go in and out of MPI: INIT .... FINALIZE .... INIT .... FINALIZE I've looked at the standard and that's what Section 8.7 says to me. So am I correct in assuming that this will change that text to say that you can start, stop, and start new "MPI epochs"?

The hybrid working group will be hosting a plenary on Friday afternoon in Madrid.

We will be presenting a proposal on MPI_INIT/MPI_FINALIZE regarding interaction with threads (going back to the use cases Jeff Hammond raised at a prior Forum meeting), and nested MPI_INIT/MPI_FINALIZE. This is not a formal reading; we're requesting Forum feedback on the overall ideas.

The slides are attached. See you in Madrid.
