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"?

Thanks,
Wesley

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.
