+# Purpose: Test of Slurm functionality
+#          Confirm that memory per cpu properly set on an srun job that
+#          does not have a preexisting allocation.
+#
+# 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.
