High Quality Content by WIKIPEDIA articles! The Bigben Supercomputer is a Cray XT3 MPP system with 2068 nodes located at Pittsburgh Supercomputing Center. Bigben is also a part of the Teragrid. "BigBen is a Cray XT3 MPP system with 2068 compute nodes linked by a custom-designed interconnect. Twenty-two dedicated IO processors are also connected to this network. Each compute node has two 2.6 GHz AMD Opteron processors. Each compute processor has its own cache, but the two processors on a node share 2 GB of memory and the network connection." -- Pittsburgh Supercomputing Center Website "There are multiple front end processors, which are also AMD Opteron processors and which run SuSE Linux. Logins are to one of these front end processors, not to the compute processors." -- Pittsburgh Supercomputing Center Website
