At 03:30 of May 26, 2008 hours, Memorial Day, has exceeded the supercomputer "Roadrunner" sustained speed of 1 petaflop / s or 1 million billion calculations per second. The sustained performance makes Roadrunner more than twice as fast the current number 1 system in the TOP500 list. The best sustained performance to date is 74.5% efficiency, 1.026 petaflop / s. "Petaflop / s" is computer jargon PETA is the number 1 with 15 zeros (sometimes called a quadrillion) and flop / s importance"The operations to double precision floating point per second." Los Alamos is the fastest supercomputer available in 1993 with the Thinking Machines CM-5 has opened, and was super-computer, support for the development of the Cray-1 in 1976. The Laboratory and IBM go all the way back to the first card-programmable calculators, used at Los Alamos in 1949. Los Alamos and serial number is one of the IBM 704 in 1956. The Roadrunner supercomputer from 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, let alone in a car-a-kind. It also uses a Linux operating system. The secret of its performance record is a unique hybrid design. Each compute node in this cluster has two AMD Opteron ™ dual-core processors plus four PowerXCell 8iTMProcessors ...
