Projects are provided with several storage areas for the data they need. Project directories provide members of a project with a common place to store code, data files, documentation, and other files related to their project. While this information could be stored in one or more user directories, storing in a project directory provides a common location to gather all files.

The following table summarizes project-centric storage areas available on OLCF resources and lists relevant policies.

Area Nickname Path Type Quota Backups Purge Retention
Project Home – /ccs/proj/[projectid] NFS 50 GB Yes Not purged 1 month after project deactivation
Project Work “Spider” /tmp/proj/[projectid] Lustre 2 TB No Not purged Not retained
Project Archive “HPSS” /proj/[projectid] HPSS 100 TB (or 100k files) No Not purged 3 months after project deactivation
Important! Files in Project Work directories are not backed up.
