What is TACC?
Texas Advanced Computing Center provides:
...
Cluster systems are made up of multiple computers, connected together to act as one. Each computer is considered called a node in the cluster and can have multiple processors (called processorscores). Users log in to the cluster through a limited number of head nodes and submit jobs to the many compute nodes. These systems are inherently parallel and can be greatly beneficial when your jobs are also parallelized.
LONESTAR:
- 1906 1888 nodes (computers)
- 22,656 cores (processors)
- Max run time: 24 hours
- USE: For running large, parallel computation jobs.
...
- Replicated storage
- 6 Petabytes of storage
- Accessible on lonestar and stampede systems
- $250 per terabyte (First 5 terabytes free for UT users)
- USE: Backup data, analysis results.
RANCH:
- Tape storage-------
- Archival storage- not replicated or backed up.
- 60 Petabytes of storage
- Immediate access can be difficult.
- USE: Long term archival of data. One of two copies.
