Roadrunner petaflop supercomputer barrier exceeds by Video Clips.

At 3:30 on the clock May 26, 2008, Memorial Day, each of the supercomputer "Roadrunner," a sustained speed of 1 petaflop / s, or 1 million billion calculations per second. The sustained performance makes Roadrunner more than twice as fast as the current system number 1 in the TOP500 list. The best sustained performance to date is 74.5% efficiency, 1.026 petaflop / s. "Petaflop / s" is jargon-peta computer is the number 1 followed by 15 zeros (sometimes called a quadrillion) and importance on the flop / s, followed"Double precision floating point operations per second." Los Alamos, instead of the current fastest supercomputer title in 1993 with the Thinking Machines CM-5, and inaugurated the era of supercomputers, support for the development of the Cray-1 in 1976. The Laboratory and IBM go all the way up to the first card-programmable calculators, used at Los Alamos in 1949. Los Alamos and the serial number 1 of the IBM 704 is 1956. The Roadrunner supercomputer developed by IBM in collaboration with the laboratoryand the National Nuclear Security Administration, uses commercially available hardware, including aspects of commercial game console and graphics technologies. Because of its off-the-shelf components, the cost of the computer much less than a one-of-a-kind machine. It also uses a Linux operating system. The secret of its performance record is a unique hybrid. Each compute node in this cluster consists of two AMD Opteron ™ dual-core and four PowerXCell 8iTMProcessors ...
