Bigben (computer)

Last updated

The Bigben supercomputer was a Cray XT3 MPP system with 2068 nodes located at Pittsburgh Supercomputing Center. [1] [2] It was decommissioned on March 31, 2010. [3] Bigben was a part of the TeraGrid. [2]

System architecture

BigBen was a Cray XT3 MPP system with 2,068 compute nodes linked by a custom-designed interconnect. [2] [3] Twenty-two dedicated IO processors were also connected to this network. [3] [4] Each compute node had two 2.6 GHz AMD Opteron processors. [3] [5] Each compute processor had its own cache, but the two processors on a node shared 2 GB of memory and the network connection. [3] [5]

Operating system

Bigben ran Catamount, a subset of Unix. [5] [6] On Bigben's front-end processors, SUSE Linux was used. [5]

File system

Bigben had two file systems comprising together over 200 TB of storage space. [5]

Compilers

Bigben had Portland Group, GNU, and UPC compilers installed. [5]
