+TODO: The recommended approach by NERSC for running tasks with intensive I/O tools (most of our tools), is to utilize 
+the scratch directory. Before executing the task, source data and reference libraries should be copied to the scratch 
+directory. Soft links (such as for collection sources) should be created as needed. Once the task is complete, 
+the results should be copied back to the user's directory. For more information, refer to the NERSC documentation:
