Tianhe-2 is a supercomputer built by the National University of Defense Technology in China.[1] It can do more than 33,862 million million operations every second. It is the fastest computer in the world.[2][1] It is twice as fast as the Tianhe-1, the previous fastest supercomputer.[2] It is predicted to become even faster by 2015, reaching speeds of 100,000 million million operations every second.[3] The computer's name means "milky way".[1] The building of Tianhe-2 was expected to be finished in 2015, but was finished in 2013 instead.[4] Proposed applications for the supercomputer include physics-related applications, such as studying combustion and magnetism. It is also being used to model the atmosphere.[5]

It has been said that Tianhe-2 "may be too powerful for most tasks".[6]

Statistics[change | change source]

Tianhe-2 can do 33,862 trillion operations per second. It could possibly do 54,900 trillion operations per second.[7][1] It uses more than three million processor cores.[7] The supercomputer uses 17.8 million watts of power.[8] The cost of construction was 2.4 billion yuan.[6]

Records[change | change source]

Tianhe-2 has been ranked at the top of the Top500 list twice, in June 2013 and November 2013.[9]
