China's super computer Tianhe-1 has overtaken us's jaguar system to gain top spot as the world's fastest computer.
Housed at the national centre 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, chinese news agency xinhua reported on Thursday.
On the biannual the world top 500 list published in june, china's nebulae machine had took the second spot only after the us's jaguar system, while tianhe-1 took seventh place.
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. 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. 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 defence technology (nudt) said.
Tianhe-1 has begun trial use among target clients including Tianjin meteorological bureau and the national offshore oil corporation data centre. "It can also serve the animation industry and bio-medical research," said liu guangming, director of the national center for supercomputing in tianjin.
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. 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.
