/scratch#
Usage#
Each cluster features its own dedicated /scratch filesystem, optimized for high-performance operations through carefully designed hardware and software configurations.
These filesystems are specifically engineered to handle large streams of raw data efficiently, making them the ideal location for directing the output of your jobs.
Each user is provided with a personal /scratch/<gaspar_user> directory, accessible exclusively to them.
Scratch policies#
If the /scratch file system gets full, Slurm automatically drains all the
running jobs. To prevent this, we have established:
- A 30-days file deletion policy.
- Occupancy limits that trigger a series of automated actions.
- Policy compliance rules to ensure fair resource sharing.
30-days file deletion policy#
Files older than 30 days are automatically removed daily. Please do not use the
/scratch file system for long-term storage.
Please transfer regularly your important data to a more permanent location, for
example, to the /work file system or your personal /home/<gaspar_user> storage.
Occupancy limits#
- At 60% occupancy, we urge immediate action to delete unnecessary data.
- If occupancy reaches 80%, an automatic cleanup process will activate during the night. It will remove files and folders, prioritizing the oldest ones first until occupancy falls below 80%.
- Please note in this case, this may include the removal of files less than 30 days old.
Policy compliance#
Use of the touch command or similar techniques to prevent file deletion is
strictly prohibited. This action contravenes our community's resource-sharing principles.
Price#
The cost of using /scratch is included in the compute services, so there are no additional charges for it.
