Re: [OMPI users] OpenMPI crashes with TCP connection error

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: https://slurm.schedmd.com/mpi_guide.html#open_mpi -Joachim From: users on behalf of Mccall, Kurt E.
