[slurm-users] LAST TASK ID

[Michael Gutteridge]

Hi

The environment variable SLURM_ARRAY_TASK_MAX might be used for this as
well, e.g.:

    if [ $SLURM_ARRAY_TASK_ID -eq $SLURM_ARRAY_TASK_MAX ]
    then
       # last task
    fi

Though I'd caution that if you need this to run after all the jobs in the
array are _complete_, you should use a job dependency.  Not sure how your
scheduling is set up, but in our setup there's no guarantee that task 10
will complete before task 11.
