[OMPI devel] Slurm integration and rankfiles....
Hi all, Using a rather trivial example mpirun -np 1 -rf rankfile ./HelloWorld on a Slurm system; -- While trying to determine what resources are available, the SLURM resource allocator expects to find the following environment variables: SLURM_NODELIST SLURM_TASKS_PER_NODE However, it was unable to find the following environment variable: SLURM_TASKS_PER_NODE -- (Both for OpenMPI 4.0/4.1). It is correct the variable is not set, but why is SLURM_TASKS_PER_NODE expected or required when using a rankfile where one presumes it would not be a constant across the job anyway? Martyn

[OMPI devel] Open MPI v5.0.x branch created
Open MPI developers, We've created the Open MPI v5.0.x branch today, and are receiving bugfixes. Please cherry-pick any master PRs to v5.0.x once they've been merged to master. We're targeting an aggressive but achievable release date of May 15th. If you're in charge of your organization's CI tests, please enable for v5.0.x PRs. It may be a few days until all of our CI is enabled on v5.0.x. Thanks everyone for your continued commitment to Open MPI's success. Josh Ladd, Austen Lauria, and Geoff Paulsen - v5.0 RMs
