Hello Geoffrey Paulsen, Can you share new release date of 5.0? I wonder what it means.

Open-MPI v5.0 branch date pushed back to May 14th (Geoffrey Paulsen) ---------------------------------------------------------------------- Message: 1 Date: Tue, 28 Apr 2020 19:28:23 +0000 From: Ralph Castain <r...@open-mpi.org> To: OpenMPI Devel <devel@lists.open-mpi.org> Subject: [OMPI devel] ORTE->PRRTE: some consequences to communicate to users Message-ID: <01010171c2430206-899d2eeb-6b32-442c-a60e-33ce860d1ec1-000...@us-west-2.amazonses.com> Content-Type: text/plain; charset=UTF-8 So here is an interesting consequence of moving from ORTE to PRRTE. In ORTE, you could express any mapping policy as an MCA param - e.g., the following: OMPI_MCA_rmaps_base_mapping_policy=core OMPI_MCA_rmaps_base_display_map=1 would be the equivalent of a cmd line that included "--map-by core --display-map" When defining what we wanted on the OMPI v5 cmd line, we removed some options like --display-map and replaced them with modifiers, so the above would have been replaced with: OMPI_MCA_rmaps_base_mapping_policy=core:display The move to PRRTE, however, means more than just changing the "OMPI" to "PRRTE". PRRTE doesn't support setting the default mapping policy to include "report" as that would mean we would be reporting the map for every job that was ever launched. Definitely not something the persistent DVM users would appreciate! So if you put: PRRTE_MCA_rmaps_default_mapping_policy=core:display (note the name change!!!) in your environment, you are going to get an error when you execute "mpirun": ===== A mapping policy modifier was provided that is not supported as a default value: Modifier: display You can provide this modifier on a per-job basis, but it cannot be the default setting. ======= And you will error out. However, it is perfectly okay to put "--map-by core:display" on your cmd line - that is legit and understood as it only applies to that specific job. It's these changes, plus the name changes (e.g., we replace "base" with "default" to emphasize these are ONLY the default settings), that will need to be communicated.
