Am I mistaken in remembering that MPI doesn't allow an application to go
in and out of MPI:

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,

    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.
