For the third consecutive time, Tianhe-2, a supercomputer developed by China’s National University of Defense Technology, has retained its position as the world’s No. 1 system with a performance of 33.86 Pflop/s (quadrillions of calculations per second) on the Linpack benchmark, according to the 43rdedition of the twice-yearly TOP500 list of the world’s most powerful supercomputers.
In fact, there was little change among the ranking of the world’s top 10 supercomputers in the latest edition of the closely watched list. The only new entry was at number 10—a 3.14 Pflop/s Cray XC30 installed at an undisclosed U.S. government site.
A detailed analysis of the latest TOP500 list will be presented Monday, June 23, at the International Supercomputing Conference in Leipzig, Germany. At that time, the full list will also be published at TOP500.org.
Although the United States remains the top country in terms of overall systems with 233, this is down from 265 on the November 2013 list. The number of Chinese systems on the list rose from 63 to 76, giving the Asian nation nearly as many supercomputers as the UK, with 30; France, with 27; and Germany, with 23; combined. Japan also increased its showing, up to 30 from 28 on the previous list.
