Bug#954272: slurmd: SLURM not working with OpenMPI
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.
Regards,
Lars
