| Operating System: | Linux | |
| Number of Nodes: | 1,888 | |
| Number of Processing Cores: | 22,656 | |
| Interconnect Type: | Quad Data Rate (QDR) InfiniBand | |
| Total Memory: | 44 TB | |
| Peak Performance: | 302 TFlops | |
| Total Disk: | 276 TB (local), 1000 TB (global) | |
| File System: | Lustre | |

The TACC Dell Linux Cluster contains 22,656 cores within 1,888 Dell PowerEdge M610 compute blades (nodes), 16 PowerEdge R610 compute-I/O server-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). A QDR InfiniBand switch fabric interconnects the nodes (I/O and compute) through a fat-tree topology, with a point-to-point bandwidth of 40GB/sec (unidirectional speed).
Compute nodes have two processors, each a Xeon 5680 series 3.33GHz hex-core processor with a 12MB unified L3 cache. Peak performance for the 12 cores is 160 GFLOPS. The new Westmere microprocessor (basically similar to the Nehalem processor family, but using 32nm technology) has the following features: hex-core, shared L3 cache per socket, Integrated Memory Controller, larger L1 caches, Macro Ops Fusion, double-speed integer units, Advanced Smart Cache, and new SSE4.2 instructions. The memory system has 3 channels and uses 1333 MHz DIMMS.
