# Purpose: Test of srun functionality
#          Test of hostfile option (-hostfile) inside of an 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.
