1 Overview
The cluster storage system provides a large parallel file system based on IBM Spectrum Scale for $HOME, for workspaces and for temporary storage via the $TMPDIR environment variable
| $HOME | Workspaces | $TMPDIR | |
|---|---|---|---|
| Visibility | global | global | global |
| Lifetime | permanent | workspace lifetime | batch job walltime |
| Capacity | 5.2 PB | 5.2 PB | 128 GB per node (9 TB per fat node) |
| Quotas | 200 GB | 10 TB | none |
| Backup | no | no | no |
- global: all nodes access the same file system.
- permanent: files are stored permanently.
- workspace lifetime: files are removed at end of workspace lifetime.
- batch job walltime: files are removed at end of the batch job.
