The purpose of this document is to provide guidelines for using the global scratch storage space connected to the Berkeley Research Computing supercluster.
Every user has a scratch space located at /global/scratch/<username>. There are no limits on the use of the scratch space, though it is an 885 TB resource shared among all users.
Files stored in this space are not backed up; the recommended use cases for scratch storage are:
- Working space for your running jobs (temporary files, checkpoint data, etc.)
- High performance input and output
- Large input/output files
Please remember that global scratch storage is a shared resource. We strongly urge users to regularly clean up their data in global scratch to decrease scratch storage usage. Users with many terabytes of data may be requested to reduce their usage, if global scratch becomes full.
If you have any questions or concerns about global scratch storage, please contact us at firstname.lastname@example.org. If you have other concerns about managing your research data, please contact Research Data Management at email@example.com.
