So the number you are looking for needs to be unique per node only?
What about using the additional group ID then which SGE creates – this will be
unique per node.
This can be found in the `id` command's output or in location of the spool
directory for the execd_spool_dir in
${HOSTNAME}/active_jobs/${JOB_ID}.${TASK_ID}/addgrpid
