Yes, the top-level /scratch directory on our batch nodes is the same as using /tmp. On our interactive nodes, /scratch is a separate 1TB shared storage space.
Top level scratch space is world-writeable and -readable (Unix 1777 permissions). User created directories are only owner writeable/readable (1700) or owner/group (2770) if you are a member of a research group.
In either case, if you need several gigabytes of storage, please request a project directory.
Please note:
- Do not store any Confidential Information in scratch/temp.
- Any files written to scratch/temp will be deleted after 2-4 weeks.
- Do not use the scratch space for permanent storage.
- Each server has a separate scratch/temp. If you need shared space for a distributed batch job, please request a project directory.
