Package: slurmd Version: 19.05.3.2-2+b1 Severity: important Dear Maintainer,
I am trying to get SLURM working on a single node. I have installed and configured slurmd and slurmctld. A simple test like `srun hostname` works, even on multiple cores. However, when trying to use MPI, it crashes with the following error message: *** An error occurred in MPI_Init *** on a NULL communicator *** MPI_ERRORS_ARE_FATAL (processes in this communicator will now abort, *** and potentially your MPI job) This happens even in the most simple "Hello World" case, as long as the program is MPI-enabled. I am trying to use OpenMPI (4.0.2) from the Debian repositories. `srun --mpi list` returns: srun: MPI types are... srun: openmpi srun: pmi2 srun: none I have tried all options, but the result is the same in all cases. Maybe this is user error, as this is my first time setting up SLURM, but I have not been able to find any possible causes/solutions and I am kind of stuck at this point.
