############################################################################
# Purpose: Test of Slurm functionality
#          Confirm that srun stdin, stdout, and stderr options work (--input,
#          --output, and --error option respectively).
#
# Note:    This script generates and then deletes files in the working directory
#          named test1.8.input, test1.8.output, and test1.8.error
