ASCI White is a Supercomputer at the Lawrence Livermore National Laboratory in California . It is a Computer Cluster based on IBM 's commercial RS/6000 SP computer. 512 of these machines are connected together for ASCI White, with 16 Processor s per node and 8,192 processors in total with 6 Terabyte s of memory and 160 terabytes of disk storage. Despite these formidable statistics, each processor is slow by 2005 standards, operating at a mere 375 MHz. Therefore, it is almost exclusively used for computations requiring dozens of processors. The computer weighs 106 tons and consumes 3 MW of electricity with a further 3 MW needed for cooling. It has a theoretical processing speed of 7,226 Gigaflops . The system runs IBM's AIX Operating System . ASCI White is made up of three individual systems, the 512 node White, the 28 node Ice and the 68 node Frost. The system was built in Poughkeepsie, New York . Completed in June 2000 it was transported to specially built facilities in California and officially dedicated on August 15 , 2001 . Claimed performance was 12,300 gigaflops, although this was not achieved in the widely accepted LINPACK tests. The system cost $110 million. It was built as stage three of the Accelerated Strategic Computing Initiative (ASCI) started by the U.S. Department Of Energy and the National Nuclear Security Administration to build a simulator to replace live Nuclear Testing following the Moratorium on testing started by President George H. W. Bush in 1992 and extended by Bill Clinton in 1993 . EXTERNAL LINK |
