Scratch files for computational jobs can be stored in /egr/scratch. /egr/scratch is available from all central login and compute servers. Files or directories more than 7 days old on /egr/scratch are removed because scratch space is temporary space. /egr/scratch is never backed up. Files needed for long-term usage or archives should be stored in another directory that is backed up, such as /home or /egr/research.
