What is TACC?
Texas Advanced Computing Center provides:
- High performance computing systems- large clusters, capable of running highly parallel computation and advanced visualization.
- Large data storage and data archival capabilities.
- Software packages already installed on the clusters.
To find documentation/training on TACC systems: User guides, training courses offered by TACC and CCBB.

TACC's Cluster Systems
Cluster systems are made up of multiple computers, connected together to act as one. Each computer is called a node in the cluster and can have multiple processors (called cores). 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.
LONESTAR5:
- 1252 nodes (computers)
- 30,000 cores (processors)
- 8 large memory nodes (512 GB of RAM) and 2 huge memory nodes (1TB of RAM)
- Max run time: 48 hours (24 for large and huge memory nodes)
- USE: For running large, parallel computation jobs.
STAMPEDE2:
- 4,200 KNL nodes (computers); 1736 SKX nodes (computers)
- 285,600 cores (processors); 83,328 cores (processors)
- Max run time: 48 hours (without approval), 120 hours (with approval)
- USE: For running large, parallel computation jobs
TACC's Data Storage Systems
- 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.
