Dear SP User, As the /scratch filesystem is now at 93% of capacity, we would like to remind SP users of the purge policy in /scratch. This filesystem is now very close initiating purging files to prevent its being filled. Scratch space on the SP is referred to by the environment variable $SCRATCH. This is not permanent storage: files will usually remain here for 7 days after they are created, after which time they may be purged. Note, however, that if the $SCRATCH filesystem becomes oversubscribed files may have to be deleted even before the 7 days are up (in which case the oldest files are deleted first). Directories themselves will not be purged. If you've become accustomed to storing files other than temporary ones in $SCRATCH please look into archival storage, deleting unneeded data or moving files you need to keep to your $HOME directory. If you have questions about file storage please see http://hpcf.nersc.gov/computers/SP/storage.php#Work or contact consult_at_nersc_dot_gov . Regards, David Skinner
