On Pinnacle/Karpinski we currently only support interactive jobs on single nodes from one core to the number of the cores in the node. So always –nodes=1 with srun. MPI is supported, just not multiple-node interactive MPI.

slurm interactive, like torque interactive, will hang your terminal until the job starts. This is for an entire node (32 cores or tasks), which is more than a typical requirement for an interactive job (often 1 core).

srun --nodes=1 --ntasks-per-node=1  --cpus-per-task=32 --partition comp06 --time=6:00:00 --pty /bin/bash
