The Cray XT-5 System is a unique Linux computing platform. Unlike other clusters here at ARL, and in the DoD program, it is not a commodity cluster. It runs a full Linux installation on the login nodes with Cray's CLE( Cray Linux Environment) running on the compute nodes. The MRAP system is built using AMD Opteron quad-core processors running 2.3 GHz with a distributed memory architecture. All of this computing power is interconnected via Cray's proprietary SeaStar network. Each compute blade consists of 4 compute nodes. Each node is composed of 2 AMD quad-core processors and 32 GB of memory. This produces an ultra-dense high performance computing platform consisting of 8 login nodes and 1300 Compute nodes to deliver 95.68 TeraFlops.
