Roadrunner Supercomputer Breaks the Petaflop Barrier Video Clips.
At 3:30 on the clock May 26, 2008, Memorial Day, each of the supercomputer "Roadrunner," a constant 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 of the TOP500 list number 1. The best sustained performance to date is 74.5% efficiency, 1.026 petaflop / s. "Petaflop / s" is computer jargon-peta is the number 1 followed by 15 zeros (sometimes called a quadrillion) and flop / s meaning, followed"Double precision floating point operations per second." Los Alamos has held the title of fastest supercomputer in 1993 with the Thinking Machines CM-5, and opened the super-computer era, assistance in developing 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, which is the IBM 704 in 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 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 processors plus four PowerXCell 8iTMprocessors ...
