User directories
When you log into the teaching GPU cluster machines, the following file systems are available:
| File system | Expiry | Access | Purpose |
|---|---|---|---|
| /work/$USER | Yes (no backup) |
Unified | Active data files. Auto mounted. |
| /scratch/$USER | Post-job (no backup) |
Per-node | Node local scratch, caching |
Where:
- Per-node: means the volume is unique to each machine
- Unified access: means the volume is mounted on all Linux machines in the cluster
- Headnode: means the volume is mounted only on the headnode. Cannot be used to launch a job on the cluster because the compute nodes cannot see it.
