- Bigben
The Bigben Supercomputer is a Cray XT3 MPP system with 2068 nodes located at
Pittsburgh Supercomputing Center . Bigben is also a part of theTeragrid .System Architecture
"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." -- [http://www.psc.edu/machines/cray/xt3/bigben.html 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." -- [http://www.psc.edu/machines/cray/xt3/bigben.html Pittsburgh Supercomputing Center Website]
Operating System
Currently Bigben runs Catamount, a subset of Unix.
File System
Bigben has two file systems comprising together over 200 TB of storage space.
Compilers
Currently Bigben has the Portland Group, the Gnu, and UPC compilers installed.
Purpose
The Bigben supercomputer is developed to help scientific researchers conduct their research.
