This might not be the reason for what you observe, but I believe deleting the scratch dir in the task epilog is not a good idea. The task epilog is run after every "srun" or "mpirun" inside a job, which means that the scratch dir will be created and deleted for each job step. On our systems, we create the scratch dir in the (slurmd) Prolog, set the environment variable in the TaskProlog, and delete the dir in the (slurmd) Epilog. That way the dir is just created and deleted once. > I am not sure I understand what constitutes a job step. In practice, every run of srun or mpirun creates a job step, and the job script itself counts as a job step. -- B/H
