-This instructs the compute node to schedule the IO traffic with "best effort" scheduling class and lowest priority for the scripts process ID and any processes launched from the script. This seems to have a positive effect on the client's IO traffic that hits the NFS mounted filesystem.
+This instructs the compute node to schedule the IO traffic with "best effort" scheduling class and lowest priority for the scripts process ID and any processes launched from the script. This seems (surprisingly, perhaps because of IpoIB?) to have a positive effect on the client's IO traffic that hits the NFS mounted filesystem. It has a tremendous positive impact when issued on the file server itself so perhaps a monitor script is needed in the future.
-Example using the /sanscratch area, you must stage your data in the temporary work directory and save results back to your home directory before the job finishes. The scheduler will automatically remove and delete that work directory.
