If the Stig was more into computers than he was cars, he'd be mighty proud right now, as IBM has overtaken Fujitsu with their brand new supercomputer that is now the fastest... in the world.
IBM's Sequoia takes pole position on the list of the world's fastest supercomputers, and bumps down Fujitsu's effort down to second place. The newly crowned champion will be used to carry out simulations to help extend the life of ageing nuclear weapons, thus avoiding the need for real-world tests that could be potentially hazardous.
Sequoia is 1.55 times faster than Fujitsu's K, clocking in at an incredible 16.3 petaflops, and uses over 1.5 million processors -- which is more than double than its rival. But despite using more processors and being even faster, Sequoia also consumes a lot less energy, making it much more efficient, which makes its triumph even more impressive. [BBC, io9]
