System Architecture
BigBen was a Cray XT3 MPP system with 2068 compute nodes linked by a custom-designed interconnect. Twenty-two dedicated IO processors were also connected to this network. Each compute node had two 2.6 GHz AMD Opteron processors. Each compute processor had its own cache, but the two processors on a node shared 2 GBGigabyte
The gigabyte is a multiple of the unit byte for digital information storage. The prefix giga means 109 in the International System of Units , therefore 1 gigabyte is...

File System
Bigben had two file systems comprising together over 200 TBTerabyte
The terabyte is a multiple of the unit byte for digital information. The prefix tera means 1012 in the International System of Units , and therefore 1 terabyte is , or 1 trillion bytes, or 1000 gigabytes. 1 terabyte in binary prefixes is 0.9095 tebibytes, or 931.32 gibibytes...
