Chinese Supercomputer Overtakes Jaguar


November 15, 2010

China's National University of Defense Technology's Tianhe-1A supercomputer has taken the top ranking from Oak Ridge National Laboratory's Jaguar supercomputer on the latest Top500 ranking of the world's fastest supercomputers. The Tianhe-1A achieved a performance level of 2.67 petaflops per second, while Jaguar achieved 1.75 petaflops per second. The Nebulae, another Chinese-built supercomputer, came in third with a performance of 1.27 petaflops per second.

"What the Chinese have done is they're exploiting the power of [graphics processing units], which are . . . awfully close to being uniquely suited to this particular benchmark," says University of Illinois Urbana-Champagne professor Bill Gropp. Tianhe-1A is a Linux computer built from components from Intel and Nvidia. "What we should be focusing on is not losing our leadership and being able to apply computing to a broad range of science and engineering problems," Gropp says.

Overall, China had five supercomputers ranked in the top 100, while 42 of the top 100 computers were U.S. systems.
