China to challenge U.S. supercomputer Dawning "nebulae" catching up "Puma".

<P Align=center> </ P> <P align=center> Dawn "Nebula" super computer </ P> <P> a Monday scientists from the United States and Europe jointly announced a global Top 500 Supercomputer ."TOP500" shows that China's supercomputer has been in operation speed can challenge the United States, Shenzhen National Supercomputing Center for use of a "cloud" computing speed has been super 1270000000000000 times per second, after the U.S. Department of Energy in Tennessee .Oak Ridge National Laboratory has a state of "Jaguar" supercomputer. .</ P> <P> TOP500 list is the world's most authoritative ranking of supercomputers, the list in order to test the value of a super computer system Linpack benchmark ranking, published twice a year. .In the Linpack benchmark, the "Nebula" performance 1270000000000000 times per second. .TOP500 said, "nebula" has the ability to 1,750,000,000,000,000 times per second rate of sustained operations. .In addition to "Nebula", the Chinese National Defense University developed the "Milky Way One" also ranked No. 7, which is China's first super computer has two top 10 ranks. .</ P> <P align=center> </ P> <P align=center> "Jaguar" supercomputer </ P> <P> </ P> <P> top-ranked Tennessee remain in the United States Department of Energy .Oak Ridge National Laboratory to use the state's "Jaguar" supercomputer, according to Top500LInpack test results, "Jaguar" supercomputer able to 1,750,000,000,000,000 times / s speed of operation. ."Puma" operation 1 second, equivalent to an ordinary personal computer operating 10 hours; its operation 1 hour, equivalent to 4 years of general computer operations. .</ P> <P> "Nebula" by Tianjin Hi-tech Industrial Development Zone, the "dawn of the industrial base in Tianjin," the research, will be formally delivered to the end of 2010 the national supercomputer center in Shenzhen, mainly used for scientific computing, the Internet intelligent search, gene .sequencing and other fields. ."Nebula" of the theoretical peak computing speed, it is estimated 3000000000000000 times per second, effectively become the world's fastest. .</ P> <P> According to TOP500, the world's top 500 supercomputers in the United States has 282, 114 in Europe (which has 38 UK, France has 29, Germany has 24), 24 in China, 18 .Ministry in Japan, five in India. .</ P> <P> "New York Times" commented that China is challenging U.S. hegemony in this field. .In the article, "nebula" in one fell swoop over a large number of European and Japanese systems, highlights China's growing strength in science and technology and ambition. .</ P>.
