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.

What is a cluster?

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 login/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.
