 ### GNU Parallel, Shared jobscript
 
-A combined approach, very similar to job arrays, can be taken. A job array is submitted to the queuing system. The subjobs run GNU parallel. The GNU parallel shell executes multiple instances of the jobscript using all of the cores on the node. The instances execute different work, controlled by the $PBS_JOB_ARRAY and the $PARALLEL_SEQ variables.

-In this example, the jobscript executes in multiple instances in parallel, on all cores of a computing node. The $TASK variable expands to one of the input filenames from the tasklist. We copy the input file to local scratch memory, execute myprog.x and copy the output file back to the submit directory, under the $TASK.out name.  The numtasks file controls how many tasks will be run per subjob. Once a task is finished, a new task starts, until the number of tasks in the numtasks file is reached.
