# Purpose: Test of SLURM functionality
#          Test srun handling of SIGINT to get task status or kill the job
#          (--quit-on-interrupt option).
#
# Output:  "TEST: #.#" followed by "SUCCESS" if test was successful, OR
#          "FAILURE: ..." otherwise with an explanation of the failure, OR
#          anything else indicates a failure mode that must be investigated.
