World’s Fastest Supercomputer|Tianhe-1A

World’s fastest supercomputer the Tianhe-1A was designed by the National University of Defense Technology in China, has set a new performance record at 2.507 petaflops via 7,168 NVIDIA GPUs and 14,336 CPUs, unseating the Cray XT5 Jaguar at Oak Ridge National Labs as the world record holder.It will be operated as an open access system for high-powered, large scale scientific computations. Costing $88 million, Tianhe-1A weighs 155 tons and consumes 4.04 megawatts of electricity.

The system uses 7,168 NVIDIA® Tesla™ M2050 GPUs and 14,336 CPUs; it would require more than 50,000 CPUs and twice as much floor space to deliver the same performance using CPUs alone.
