# Spawn srun with $task_cnt tasks each of which runs a $mult way /bin/id
#

# NOTE: The inner srun needs to use --cpu-bind=quiet option so that it ignores
# SLURM_CPU_BIND environment variable that gets set if task/affinity plugin is
# used. Each node could have a diffenent cpu mask specified by SLURM_CPU_BIND
# making any tasks launched from that node be required to use the same mask
# leading to "CPU binding outside of job step allocation" errors.
