China "Tianhe No. two" super computer to return to the top of the world xinhuanet.com Washington on 17 June, (reporter Lin Xiaochun) after two and a half years later, China super computing speed back to the top of the world. International TOP500 organization announced the 17 latest supercomputers in the world 500 strong list, development of China National Defense Science and Technology University "Milky Way No. two" to 33.86 quadrillion floating-point operations per second, become the world's fastest supercomputer.
In contrast, the United States Department of energy's Oak Ridge National Laboratory "Titan" to the order of two from the last one, the operation speed of 17.59 petaflops. The experts said, because "the Milky Way No. two" speed nearly twice as fast as second, China is likely to keep the crown for at least a year. In the future, the world's fastest supercomputers position will be possible by the three countries' computer alternate control the situation.
One of the main people in the United States, ranking compiled by University of Tennessee computer science professor Jack Tangara on-site verification of the "Milky Way No. two" speed. He told Xinhua News Agency reporter the interview said, "Tian two" impression "very deep", it has more than 3000000 computing cores, and the Internet network, operating system, front-end processors and software is the Chinese independent research and development.
The United States University of Illinois's Bana Champain, director of the William Grop Institute and parallel computing "Tianhe No. two" software development group had a series of discussion. He highly appreciated the Chinese researchers work quality and in-depth understanding of their computing software problem for high performance, and that the Internet has "China independently developed the most advanced level, making the" Milky Way "two" wide application.
Grop told reporters: "high performance computing is a key technology of modern engineering. China hopes to become a leader in the technology in twenty-first Century, in the high performance computing effort shows that China is serious. The new system continuously to develop a better guarantee China played an important role in the field of high performance computing."
Released the same day in the rankings, the United States Laurence Livermore National Laboratory, "Redwood" RIKEN "Jing", the United States Argonne National Laboratory's "Mira" in third to fifth. China "Tianhe No.1" in 2010 had topped the list, this has fallen to tenth place.
At present, more than half of the United States of America has the world's top 500 supercomputer, showing a clear advantage. China has a total of 65 super computer to enter the top 500 list, the list of 72 than in November last year declined slightly, but still ranked second. Japan ranked third to 30. Britain, France and Germany respectively by 29, 23 and 19 in the fourth to sixth place.
The experts said, in the future there will be a new round of the super computer competition. In 2010 November, "Tianhe No.1" ranks among the top 500 list, but after half an year is Japan's "Jing" more than. Since then the United States of America's "Sequoia" and "Titan" has also won the top. Chinese Academy of Sciences, computer network information center for Supercomputing Center Director Chi Xuebin think, "won the Milky Way No. two" was transient, increase investment in other countries will, is expected to soon come faster system. Illinois Institute of Technology computer science department director Professor Sun Xianhe told reporters, Japanese scientists have said publicly in the calculation of a high performance meeting, to make the "Milky Way No. two" faster machine.
International TOP500 organization published from 1993 to the global top 500 supercomputers list, this is also the world's most authoritative supercomputer list, published two times a year. List system to the measured Linpack velocity as a benchmark to rank the world super computer.
