- The/tmp/$USER/ is the local disk space in each node, allowing for fast I/O rate, but can only be accessed from the node itself. Files in /tmp/ are cleared after 7 days and space usage is limited by job. Once job is finished, temporal files are copied automatically to /scratch/$USER/tmp/$JOBID for a better availability of data.
So, as a summary:
| Name | Variable | Availability | Quota | Time limit | Backup |
|---|---|---|---|---|---|
| /home/$USER | $HOME | Global | 4GB50 - 200 GB* | UnlimitedYes |  Yes |
| /scratch/$USER | - | Global | 1TB1 TB | 30 days | No No |
| /scratch/$USER/tmp/$JOBID | $SHAREDSCRATCH | 7 days | |||
| /tmp/$USER/$JOBID | $LOCALSCRATCH | Local to node | Job file limit- | 7 days | No No |
* There is a group quota, depending on the number of users. The limits are 4, 8 and 16 GB for groups up to 5, 10 and 20 users, respectively.
The storage quota is account-wide and depends on the basic pack aquired.
The users’ home directories are offered by a NetApp FAS8020 NFS server and the shared scratch by the BeeGFS cluster.
