Working File System
Attention: The /staging filesystem is scheduled to be decommissioned and upgraded to a new, high-performing system on June 5, 2020. Please see our HPC Filesystem Status page for more information on which filesystem to use for your jobs as we complete our major filesystem upgrade.
All users should use the /staging storage area as their working space for jobs.
/staging is a parallel filesystem that is hosted on dedicated storage machines. This is a shared resource for use by all HPC researchers. Data stored in /staging is retained and not deleted between jobs.
A directory is automatically created for each HPC project under /staging so that data can be stored there temporarily. Project-specific user subdirectories are also created. All subdirectories created under /staging will automatically be set to allow project group access for easier data sharing.
Managing Files in /staging
Although files on /staging are not deleted between jobs, they are never backed up and it is very important for users to periodically copy results to a permanent project filesystem. While HPC will try to protect user files on these systems, any software or hardware failures can result in data loss.
Please remember that /staging is a resource shared among all users, so it will be monitored for overuse.
NOTE: When the /staging filesystem reaches 85% data use capacity, HPC will send an email requesting that users with the largest amount of data delete some of it. If no one responds and the filesystem reaches 90% capacity, HPC staff will begin deleting the oldest data, targeting larger data sets, in order to bring the usage back under 85%.
