China Dominates Top 500 Supercomputers List

(Yicai Global) Nov. 14 -- Chinese supercomputers Sunway TaihuLight and Tianhe-2, or Milkyway-2, took first and second on a list of the world's top 500 supercomputers for the fourth time in a row. China dominated the list from supercomputer statistics firm TOP500, with more systems than any other country.

Sunway TaihuLight's 93 trillion calculations per second (petaflops per second) and Tianhe-2's 33.9 petaflops per second topped the ranking, followed by Switzerland's Piz Daint, Japan's Gyoukou and the US's Titan.

Summit, a system the US Department of Energy is developing, could dethrone TaihuLight next year, when it comes to run with an expected performance of 200 petaflops per second, experts said. The Department of Energy is also working on the Sierra supercomputer.

A record high of 202 Chinese supercomputers made the list. The US was the second most represented country with 143 systems.

US-based groups still control the core technologies underpinning high-performance computation products such as CPUs (central processing units) and GPUs (graphics processing units), while China's application of high-performance computation and talent pools are still lagging behind those of the US and Europe, said Liu Jun, general manager the high-performance server unit at Inspur Co., one of China's largest information technology enterprises. A persistent endeavor is necessary, Liu said.
