The following are the primary computational assets:
Green, SGI Altix 3700 Bx2, originally purchased with 64 1.6GHz Itanium2 processors, 256GB of memory, and 6.4TB of scratch disk, has since been expanded to 128 processors and 576GB RAM. Its companion user node, white, is a four-processor system, suitable for compiling and short tests.
The Wilson cluster is a 512-core cluster from Western Scientific. Each of the 128 nodes contains 2 dual-core AMD Opterons running at 2.2GHz, 8GB of memory, and 100GB of local disk. The cluster is tied together with 1Gb Ethernet and Infiniband. A Lustre filesystem provides 8TB of scratch space.
The Brody cluster is a 1024-core cluster from SGI. Each of the 128 nodes contains 2 quad-core Xeons at 2.3GHz, 8GB of memory, and 250GB of local disk. Brody shares the same Ethernet and Infiniband networks as Wilson along with the Lustre filesystem.
