CIRCE Layout
The following page will describe the system layout with details on where files and directories are stored.
CIRCE Login Nodes
When a user connects via SSH to circe.rc.usf.edu, they will end up on one of several login nodes. These are the redundant, load-balancing login nodes which will allow you to access your files, develop code, submit jobs, and review your data.
Storage
CIRCE has three tiers of storage, details below:
/home
/home is your primary storage location and the default location you are assigned when you log into the system.
/homeresides on a FibreChannel SAN- Served by two NFS servers, for fail-over redundancy
- Continuously replicated to a second array
- Backed-up nightly with up to 14 days of snapshots
Home directories are laid out as follows:
/home/[a-z]/<netid>
where [a-z] is the first letter of the user’s NetID.
/shares contains folders for group collaboration. If you are a member of any groups or you create any groups, you will have a folder under /shares of the same name. /shares is
- Served by two NFS servers, for fail-over redundancy
- Continuously replicated to a second array
- Backed-up nightly with up to 14 days of snapshots
/work
/work is the storage space used when running jobs. Jobs will read and write files from /work as it is designed to be fast and responsive so as not to hold up calculations. /work is
- Based on a Lustre filesystem provided by Data-Direct Networks’ ExaScaler appliance
- NOT backed up in any way
- NOT replicated
- Regularly purged of files that have not been accessed within 6 months.
/apps
/apps contains most of the system’s third-party applications.
Clusters
CIRCE provides access to several compute cluster environments, some of which are accessible University-wide and others which are only accessible by certain research groups. Please see the queue layout documentation for more information.
