China's super computer remains world's most powerful

China's Tianhe-2 supercomputer, stated to be twice faster than its competitor in US has retained its status as the world's most powerful computer for the third time, according to a report.

Tianhe-2, which means "Milky Way-2" in Chinese, can operate at 33.86 petaflops per second, equivalent to 33,860 trillion calculations per second.

One hour of calculation by the machine equals 1,000 years of difficult sums by 1.3 billion people, coincidentally China's current population on a calculator.

It is the third time Tianhe-2 has topped the list according to a biannual Top500 list of supercomputers.

Developed by China's National University of Defence Technology, the supercomputer is a product of China's 863 high technology program, which aims to reduce  reliance on foreign technology, state run Xinhua-news agency reported.

According to a statement from the Ministry of Science and Technology, Tianhe-2 has provided computing support for more than 120 clients at the National Supercomputer Centre in Guangzhou in south China.

The development of the C919 airliner and drug testing in the Shanghai Institute of Materia Medica were both helped by Tianhe-2's super powers.

The supercomputer also came to the help of Guangzhou's e-government database and cloud computing storage.
