Intel mpirun interpreting process count incorrectly in Slurm

Intel mpirun interpreting process count incorrectly in Slurm

imagem de martijn@clustervision.com
mpirun launches only a maximum 8 processes per node, on a node that has 12 cores. I suspect this is a result of misinterpretation of the processor count from the slurm environment or some kind of limitation enforced by mpirun.

Intel MPI version:4.0.3.008 Slurm version : 2.2.4 Nodes have Intel Xeon CPU X5650 @ 2.67Ghz (12 cores) 1. Request resources via slurm. salloc -n 24 The resources are allocated properly. echo $SLURM_NNODES 2 echo $SLURM_JOB_NUM_NODES 2 echo $SLURM_NPROCS 24 echo $SLURM_TASKS_PER_NODE 12(x2) echo #SLURM_JOB_NODELIST node[049-050] 2. Run mpi job mpirun ./intelmpijob This lauches 8 processes pernode (total of 16). Any quick response will be greatly appreciated.

Dear martijn@clustervision.com,

Thank you forthe post.

Please try to run your job with

Best regards,
