Bigben (computer)

From Wikipedia, the free encyclopedia

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]
