【2010－10－29】China's supercomputer faster than US' No 1
[p=30, 2, left]BEIJING -- China's Tianhe-1 has overtaken Nebule to regain top spot as China's fastest computer, according to a new list of China's Top 100 supercomputers released Thursday.[/p][p=30, 2, left]On the biannual world TOP 500 list published in June, China's Nebulae machine took the second spot only after the US's Jaguar system, while Tianhe-1 took seventh place.[/p][p=30, 2, left]Housed at the National Center for Supercomputing in northern port city of Tianjin, Tianhe-1, meaning Milky Way, has a sustained computing speed of 2,507 trillion calculations, or 2.507 petaflops, per second. [/p][p=30, 2, left]It has a theoretical speed of 4.7 petaflops per second, according to a R&D research member of Tianhe-1. A petaflop is equivalent to 1,000 trillion calculations.[/p][p=30, 2, left]Nebulae housed in Shenzhen is capable of sustained computing of 1.271 petaflop per second (PFlop/s) on the Linpack benchmark, a measure for ranking supercomputers in world Top 500 list.[/p][p=30, 2, left]The US leads the world in supercomputing and is home to more than half of the top 500 supercomputers. The Jaguar system at Oak Ridge National Laboratory in Tennessee has a speed of 1.75 PFlop/s, now slower than China's Tianhe-1.[/p][p=30, 2, left]The enhanced Tianhe-1 has upgraded Intel CPUs, NVIDIA GPUs, and new domestically developed FeiTeng-1000 CPUs have been installed, the developer the National University of Defense Technology (NUDT) said.[/p][p=30, 2, left]Tianhe-1 has begun trial use among target clients including Tianjin Meteorological Bureau and the National Offshore Oil Corporation data center. "It can also serve the animation industry and bio-medical research," said Liu Guangming, director of the National Center for Supercomputing in Tianjin.[/p][p=30, 2, left]In September 2009, the NUDT created Tianhe-1 with a sustained computing speed of 0.5631 PFlop/s, the fastest supercomputer in China at that time.[/p][p=30, 2, left]The new technical data of Tianhe-1 has been submitted to the world Top 500 list and the next list will be released in November.[/p] Good news ,let's congratulate it!
