Located at IBM’s Thomas J. Watson Research Center in Yorktown Heights, NY, IBM’s Blue Gene Watson (BGW) is the third fastest supercomputer in the world. BGW earned that distinction by demonstrating sustained performance of 91.29 teraflops per second on the linpack benchmark. BGW’s peak performance is approximately 114 teraflops per second. BGW consists of 20 racks of hardware conforming to the BG/L architecture. Each BGW rack consists of 1024 nodes, and each node contains two 700 MHz power 440 processors and 512 MB of memory. The 20 racks are arranged as five rows of four racks each. The world’s fastest supercomputer is also is a BG/L computer. Blue Gene Watson’s primary mission is to perform production science computations that could not be successfully undertaken on less powerful computers. Except for periodic maintenance, it runs 24 hours a day seven days a week in production mode. Approximately 90% of BGW’s computational capacity is devoted to its production science mission. Within that mission BGW has target allocations of 40% protein folding; 40% for other biological simulations; and for 20% for other science. A secondary BGW mission is to enable pioneering computer science research; this mission is often fulfilled through application scaling experiments. The production science computations performed on BGW consist primarily of projects devised by IBM scientists from around the world. However, BGW also does undertake selected production science projects created by external parties. BGW is committed to run external science proposals selected by the DOE INCITE program and external science proposals selected by the BG/L Consortium for BGW Days. Users interact with BGW through its four Front End Nodes, each of which is an IBM p655 server running SLES 9 Linux.

Each BGW rack has 16 I/O nodes that are used for data input and output. Each I/O node communicates with the storage infrastructure via a gigabit Ethernet connection. The primary storage infrastructure consists of 60 terabytes of SAN-based disk storage configured using IBM's General Parallel File System

(GPFS). In addition, a 500 terabyte IBM 3494 tape library is used to back up data from the disk storage. An IBM 3580 tape drive can be used to move large data sets into, or out of, the facility. The latest addition to the BGW facility is an IBM Deep Computing Visualization System, which can produce multi-display renderings of results produced on BGW. BGW entered production on July 1, 2005, fulfilling a promise IBM made to the world in 1999 - to build a supercomputer capable of addressing the protein

folding problem. Over time, its mission expanded as the BG/L architecture’s ability to address a broad range of demanding computational problems was demonstrated. Copyright (c) 2000-2007 TOP500.Org | All trademarks and copyrights on this page are owned by their respective owners.
