[Mpi3-rma] Fwd: [Mpi-forum] MPI 3.0 overview

[William Gropp]

Though in *FIVE* years of asking for PGAS codes that we could run on Blue Waters, I've receive *ZERO* codes, and only one indirect, whose author declined to make his code available.  (And others have had similar experiences.) While PGAS interoperability could be important, I see no evidence that people are migrating away from MPI to PGAS.  If there is any quantifiable evidence, I'd like to see it.
