A Chinese supercomputer has topped a list of the world's fastest computers for the seventh straight year—and for the first time the winner uses only Chinese-designed processors instead of U.S. technology.
The announcement Monday is a new milestone for Chinese supercomputer development and a further erosion of past U.S. dominance of the field.
Last year's Chinese winner in the
TOP500 ranking maintained by researchers in the United States and Germany slipped to No. 2, followed by a computer at the U.S. government's Oak Ridge National Laboratory in Tennessee.
Also this year, China displaced the United States for the first time as the country with the most supercomputers in the top 500. China had 167 systems and the United States had 165. Japan was a distant No. 3 with 29 systems.
Supercomputers are one of a series of technologies targeted by China's ruling Communist Party for development and have received heavy financial support. Such systems are used for weather forecasting, designing nuclear weapons, analyzing oilfields and other specialized purposes.
"Considering that just 10 years ago, China claimed a mere 28 systems on the list, with none ranked in the top 30, the nation has come further and faster than any other country in the history of supercomputing," the TOP500 organizers said in a statement.
This year's champion is the Sunway TaihuLight at the National Supercomputing Center in Wuxi, west of Shanghai, according to TOP500. It was developed by China's National Research Center of Parallel Computer Engineering & Technology using entirely Chinese-designed processors.
The TaihuLight is capable of 93 petaflops, or quadrillion calculations per second, according to TOP500. It is intended for use in engineering and research including climate, weather, life sciences, advanced manufacturing and data analytics.
Its top speed is about five times that of Oak Ridge's Titan, which uses Cray, NVIDIA and Opteron technology.
Other countries with computers in the Top 10 were Japan, Switzerland, Germany and Saudi Arabia.
The TaihuLight is due to be introduced Tuesday at the International Supercomputing Conference in Frankfurt by the director of the Wuxi center, Guangwen Yang.
"As the first No. 1 system of China that is completely based on homegrown processors, the Sunway TaihuLight system demonstrates the significant progress that China has made in the domain of designing and manufacturing large-scale computation systems," Yang was quoted as saying in the TOP500 statement.
The TaihuLight uses Chinese-developed ShenWei processors, "ending any remaining speculation that China would have to rely on Western technology to compete effectively in the upper echelons of supercomputing," TOP500 said in a statement.
The second-fastest computer, the Tianhe-2 at the National Supercomputer Center in the southern city of Guangzhou, is capable of 33 petaflops. It uses chips made by Intel Corp.
Among countries with the most computers on the top 500 list, Germany was in fourth place with 26 systems, France was next with 18, followed by Britain with 12.
The TOP500 is compiled by Erich Strohmaier of NERSC/Lawrence Berkeley National Laboratory, Jack Dongarra of the University of Tennessee, Knoxville, Horst Simon of NERSC/Lawrence Berkeley National Laboratory, and Martin Meuer of Prometeus GmbH, a German technology company. Another contributor, Hans Meuer of Germany's University of Mannheim, died in 2014.
http://phys.org/news/2016-06-chinese-supercomputer-tops-world-fastest.htmlThe Sunway TaihuLight is a Chinese supercomputer that, as of June 2016, ranks as the fastest supercomputer in the world, with a LINPACK benchmark rating of 93 petaflops. This is nearly three times faster than the previous holder of the record, the Tianhe-2, which ran at 34 petaflops.
It uses a total of 40,960 Chinese-designed SW26010 multicore 64-bit RISC processors based on the ShenWei architecture. Each processor chip contains 256 general-purpose processing cores, and an additional 4 auxiliary cores for system management, for a total of 10,649,600 CPU cores across the entire system. The system runs on its own operating system, Raise OS, which is based on Linux.
It is located at the Chinese National Supercomputing Center in the city of Wuxi, in Jiangsu province, China.

Sunway TaihuLight is the new No. 1 system with 93 petaflop/s (quadrillions of calculations per second) on the LINPACK benchmark.
Developed by the National Research Center of Parallel Computer Engineering & Technology (NRCPC) and installed at the National Supercomputing Center in Wuxi, Sunway TaihuLight displaces Tianhe-2, an Intel-based Chinese supercomputer that has claimed the No. 1 spot on the past six TOP500 lists.
The newest edition of the list was announced Monday, June 20, at the 2016 International Supercomputer Conference in Frankfurt. The closely watched list is issued twice a year.
Sunway TaihuLight, with 10,649,600 computing cores comprising 40,960 nodes, is twice as fast and three times as efficient as Tianhe-2, which posted a LINPACK performance of 33.86 petaflop/s. The peak power consumption under load (running the HPL benchmark) is at 15.37 MW, or 6 Gflops/Watt. This allows the TaihuLight system to grab one of the top spots on the Green500 in terms of the Performance/Power metric. Titan, a Cray XK7 system installed at the Department of Energy’s (DOE) Oak Ridge National Laboratory, is now the No. 3 system. It achieved 17.59 petaflop/s.
Rounding out the Top 10 are Sequoia, an IBM BlueGene/Q system installed at DOE’s Lawrence Livermore National Laboratory; Fujitsu’s K computer installed at the RIKEN Advanced Institute for Computational Science (AICS) in Kobe, Japan; Mira, a BlueGene/Q system installed at DOE’s Argonne National Laboratory; Trinity, a Cray X40 system installed at DOE/NNSA/LANL/SNL; Piz Daint, a Cray XC30 system installed at the Swiss National Supercomputing Centre and the most powerful system in Europe; Hazel Hen, a Cray XC40 system installed at HLRS in Stuttgart, Germany; and Shaheen II, a Cray XC40 system installed at King Abdullah University of Science and Technology (KAUST) in Saudi Arabia is at No. 10.
The latest list marks the first time since the inception of the TOP500 that the U.S is not home to the largest number of systems. With a surge in industrial and research installations registered over the last few years, China leads with 167 systems and the U.S. is second with 165. China also leads the performance category, thanks to the No. 1 and No. 2 systems.
