# Purpose: Test of SLURM functionality
#		  test that when a job array is submitted to multiple
#		  partitions that the jobs run on all the assigned partitions
#
#
# 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.
