Yesterday at the Annual Meeting of National High Performance Computing (HPC China 2010) in Beijing. China unveiled its Tianhe-1A the world’s fastest supercomputer with a performance record of 2.507 petaflops, as measured by the LINPACK benchmark, 50 percent faster than America’s super computers.
Designed by the National University of Defense Technology (NUDT) in China, uses 7,168 Nvidia Tesla M2050 GPUs and 14,336 Intel Xeon CPUs. It cost $88 million; its 103 cabinets weigh 155 tons, and the entire system consumes 4.04 megawatts of electricity.
Tianhe-1A ousted the previous record holder, Cray XT5 Jaguar, which is used by the U.S. National Center for Computational Sciences at Oak Ridge National Laboratories. It is powered by 224,162 Opteron CPUs and achieves a performance record of 1.75 petaflops.[
