You should be doing:
srun -n X program instead of srun -n X mpiexec ... Thanks, Kiran On 09/23/2014 01:49 PM, Lev Givon wrote:
I have OpenMPI 1.8.2 compiled with PMI support enabled and slurm 2.6.5 installed on an 8-CPU machine running Ubuntu 14.04.1. I noticed that attempting to any program compiled against said OpenMPI installation via srun using srun -n X mpiexec program with X > 1 effectively is equivalent to running mpiexec -np X program X times. Is this behavior expected? Running the program via sbatch only causes 1 run over X MPI processes.
