Lonestar Essentials

Introduction

The Lonestar Linux Cluster consists of 1,888 compute nodes, with two 6-Core processors per node, for a total of 22,656 cores. It is configured with 44 TB of total memory and 276TB of local disk space. The theoretical peak compute performance is 302 TFLOPS. In addition, for users interested in large memory, high throughput computing, Lonestar provides five nodes, six cores each, each with 1TB of memory. For visualization and GPU programming, Lonestar also provides eight GPU nodes with six cores. The system supports a 1PB global, parallel file storage, managed by the Lustre file system. Nodes are interconnected with InfiniBand technology in a fat-tree topology with a 40Gbit/sec point-to-point bandwidth. A 10 PB capacity archival system is available for long term storage and backups.
