Lonestar

Powerful, multi-use HPC and remote visualization

Lonestar is one of the most productive, multi-use cyberinfrastructure HPC and remote visualization resources in the world. This Dell Linux cluster is funded by The University of Texas at Austin, UT's Institute of Computational Engineering and Sciences (ICES), UT System, Texas A&M, Texas Tech, and the National Science Foundation, and serves as a unique resource to researchers at all 15 UT System institutions.

Lonestar contains 23,184 cores within 1,888 Dell PowerEdgeM610 compute blades (nodes), 16 PowerEdge R610 compute-I/Oserver-nodes, and 2 PowerEdge M610 (3.3GHz) login nodes. Each compute node has 24GB of memory, and the login/development nodes have 16GB. The system storage includes a 1000TB parallel (SCRATCH) Lustre file system, and 276TB of local compute-node disk space (146GB/node). Lonestar also provides access to five large memory (1TB) nodes, and eight nodes containing two NVIDIA GPU's, giving users access to high-throughput computing and remote visualization capabilities respectively.

A QDR InfiniBand switch fabric interconnects the nodes (I/Oand compute) through a fat-tree topology, with a point-to-point bandwidth of 40GB/sec (unidirectional speed).
