Chinese scientists have once again built the world’s fastest supercomputer. The super computer named Tianhe-2, or Milkyway-2, has a peak performance speed of 54.9 quadrillion operations per second, said by the National University of Defense Technology (NUDT), who built this computer.

This is the second time China has made  the first place in the Top 500 list of the world’s most powerful supercomputers. Li Nan, spokesman of the Tianhe-2 project said that  “They are producing supercomputers with a fundamental purpose of providing a driving force for the construction of an innovation-oriented country and solutions to sciences that concern the future development of human beings.It will cost 100 million dollars.Jack Dongarra, one of the editors of Top 500, said he was impressed with Tianhe-2’s interconnect, operating system and software which are mainly Chinese.

The NUDT said it would produce a supercomputer performing 100 quadrillion operations per second by 2015 and further raise it by 10 times around 2020.
