New Chinese Supercomputer Named World’s Fastest

A new Chinese supercomputer debuted atop a recently released list of the world’s most powerful computing systems. The Tianhe-2, which the government-run National University of Defense Technology developed, topped the latest Top500 list with a tested performance of 33.86 petaflops (one petaflops is 1015 flops). The second and formerly top-ranked system on the biannual list is the US’s Titan—housed at the Department of Energy’s Oak Ridge National Laboratory—which performs 17.59 petaflops. The US’s Sequoia computer ranked third, followed by the Japanese K and the US’s Mira. The Tianhe-2 uses Intel Ivy Bridge and Xeon Phi chips with 3,120,000 computing cores and has a theoretical peak performance of 54.9 petaflops. Most of the components are Chinese-made, including the Kylin Linux operating system. Of the systems on the Top500, the US has 252, China now has 66, Japan has 30, the UK has 29, and France has 23. Hans Meuer of the University of Mannheim, Erich Strohmaier and Horst Simon of the US Lawrence Berkeley National Laboratory, and Jack Dongarra of the University of Tennessee, Knoxville, compile the list.
