TACC Overview

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
