Cluster Storage
There are three classes of disk storage on the cluster: home directory, scratch, and project-associated mass storage.
Home directory
Home directory storage is located at /home and is mounted from the central NAS array. Storage use is limited to 250MB per user by default but can be increased on request. This file system is globally available and is intended to house source code, binaries, and other relatively small files. This is the only storage that is backed up.
Scratch space
There are two types of scratch space: local and global. Each worker node has a locally attached disk that is available for temporary storage during the execution of a job. It is located at /state/partition1/. Available space is on the order of 100GB. Use of this space is only guaranteed during the execution of the job on that compute node.
Global scratch space is available at /data/scratch. This is a single storage space that is visible on all cluster nodes. To use this space you should create a subdirectory here using your username and store files under this directory. Files which have not been modified in the past month may be automatically deleted from this storage location.
Project-associated Mass Storage
For computing projects that have large storage requirements we offer multi-terabyte NFS shares. These shares are mounted on all compute nodes under the /data/ directory. We currently have a total of 30TB of network storage which is available on an as-needed basis for terms of 6 months or less. Please apply here:
