Tianhe-1A capable of sustained computing of 2.507 petaflops a second – 1.4 times faster than Cray XT5 Jaguar
China has overtaken the US as home of the world's fastest supercomputer. Tianhe-1A, named for the Milky Way, is capable of sustained computing of 2.507 petaflops – equivalent to 2,507 trillion calculations – each second.
The US scientist who maintains the international rankings visited it last week and said he believed it was 1.4 times faster than the former number one, the Cray XT5 Jaguar in Oak Ridge, Tennessee. That topped the list in June with a rate of 1.75 petaflops a second.
The US is home to more than half of the world's top 500 supercomputers. China had 24 in the last list, but has pumped billions of pounds into developing its computational ability in recent years. The machines are used for everything from modelling climate change and studying the beginnings of the universe to assisting aeroplane design.
Housed in the northern port city of Tianjin, near Beijing, Tianhe-1A was developed by the National University of Defence Technology. The system was built from thousands of chips made by US firms – Intel and Nvidia – but domestic researchers developed the networking technology that allows information to be exchanged between servers at extraordinary speeds.
Tianjin's weather bureau and the National Offshore Oil Corporation data centre are already using it for trial projects. "It can also serve the animation industry and bio-medical research," Liu Guangming, director of the National Centre for Supercomputing, told China Daily.
