MANNHEIM, Germany; BERKELEY, Calif.; and KNOXVILLE, Tenn.--Tianhe-2, a supercomputer developed by China’s National University of Defense Technology, is the world’s new No. 1 system with a performance of 33.86 petaflop/s on the Linpack benchmark, according to the 41st edition of the twice-yearly TOP500 list of the world’s most powerful supercomputers. The list was announced June 17 during the opening session of the 2013 International Supercomputing Conference in Leipzig, Germany.

MANNHEIM, Germany; BERKELEY, Calif.; and KNOXVILLE, Tenn.—The 36th edition of the closely watched TOP500 list of the world’s most powerful supercomputers confirms the rumored takeover of the top spot by the Chinese Tianhe-1A system at the National Supercomputer Center in Tianjin, achieving a performance level of 2.57 petaflop/s (quadrillions of calculations per second). 

HAMBURG, Germany—China’s ambition to enter the supercomputing arena have become obvious with a system called Nebulae, build from a Dawning TC3600 Blade system with Intel X5650 processors and NVidia Tesla C2050 GPUs. Nebulae is currently the fastest system worldwide in theoretical peak performance at 2.98 PFlop/s. With a Linpack performance of 1.271 PFlop/s it holds the No. 2 spot on the 35th edition of the closely watched TOP500 list of supercomputers.
