Kurt,
I think Joachim was also asking for the command line used to launch your
application.
Since you are using Slurm and MPI_Comm_spawn(), it is important to
understand whether you are using mpirun or srun
FWIW, --mpi=pmix is a srun option. you can srun --mpi=list to find the
available options
Joachim,
Sorry to make you resort to divination. My sbatch command is as follows:
sbatch --ntasks-per-node=24 --nodes=16 --ntasks=384 --job-name $job_name
--exclusive --no-kill --verbose $release_dir/script.bash &
--mpi=pmix isn’t an option recognized by sbatch. Is there an alternative?
Hi Kurt,
Without knowing your exact MPI launch command, my cristal orb thinks you might
want to try the -mpi=pmix flag for srun as documented for slurm+openmpi:
