Armis2 Storage

Every user has a /scratch directory for every Slurm account they are a member of.  Additionally for that account, there is a shared data directory for collaboration with other members of that account.  The account directory group ownership is set using the Slurm account-based UNIX groups, so all files created in the /scratch directory are accessible by any group member, to facilitate collaboration.


Please see the section on Storage Policies for more details.
