Releasev20 mpi31

MPI 3.1 and Open MPI v2.x

• MPI-3.1 Compliance
  • Ticket 349 (MPI_Aint_add) - 2.0.X candidate
  • Ticket 369 (same_disp_info key for MPI_Win_create) - 2.0.X candidate, maybe
  • Ticket 273 (non blocking coll I/O, non trivial). This is dependent on moving libnbc core out of libnbc component.
  • Ticket 404 (MPI_Aint_diff) - 2.0.X candidate
  • Ticket 357 (MPI_Initialized, MPI_Query_thread, MPI_Thread_is_main) always thread safe (probably just verify with a test to see this is true now for OMPI thread models)
• At least some MPI-3 Errata Items
  • 438, MPI_WIN_BASE attribute for shared memory windows
  • 437,434,435 - active target sync for shared memory - need to check that OMPI is okay with this one?
  • 428 - non-profile-able mpi routines
  • 419 - neighborhood coll can’t handle non-symmetric general graphs, improve error checking
  • 424 - check fortran9X/F08 interface for MPI_IMPROBE
  • 415, 345, 388, 390 more fortran interface stuff
