The fastest computer in the world today is a computer.

The fastest computer in the world is the Tianhe-2 supercomputer, Tianhe-2 is a supercomputer system developed by the National University of Defense Technology, topping the list of the world's fastest supercomputers with a peak computation speed of 549 million times a second, sustained computation speed of 339 million times a second of double-precision floating-point operations of the superior guide performance.

In the list of the world's top 500 supercomputers announced on November 17, 2014, China's Tianhe-2 won the title for the fourth consecutive time at a speed nearly twice as fast as that of the second-place U.S. Titan.

In May 2015, the numerical simulation of the 3 trillion-particle-count neutrinos and dark matter of the U.S.S.R. N-body on the Tianhe-2 was carried out successfully, which revealed the evolutionary process of the U.S.S.R. 16 million years after the Big Bang, and so far it's been about 13.7 billion years after the Big Bang, so far about 13.7 billion years of the long evolutionary process.

Tianhe-2 supercomputer

Tianhe-2 has been applied in many fields such as biomedicine, new materials, engineering design and simulation analysis, weather forecasting, smart city, e-commerce, cloud computing and big data, digital media and animation design, etc., and it will also be widely used in the fields of big science, big engineering and informatization to provide important support for the economic and social transformation and upgrading. economic and social transformation and upgrading to provide important support.

Tianhe-2 is gradually making its presence felt in a series of big sciences and big projects concerning national economy and people's livelihood, such as life sciences, material sciences, atmospheric sciences, geophysics, cosmos, economics, as well as large-scale genome assembly, gene sequencing, pollution control, and so on. In addition, the National Supercomputing Center Guangzhou actively promotes international exchanges and cooperation, using Tianhe-2 to provide high-performance computing services for foreign research institutions.

With the help of Tianhe-2's computational power, the domestic C919 large passenger airplane has carried out high-precision aerodynamic calculations of the external flow field. The Shanghai Institute of Pharmaceutical Sciences of the Chinese Academy of Sciences carried out the binding affinity assessment of 750,000 small molecule compounds, and completed the evaluation of more than 600 various types of drug activity tests in vivo and in vitro. Tianhe-2 has been adapted to the e-government data management system and cloud disk storage system of Guangzhou Municipality to build an efficient and reliable hosting platform for the construction of smart cities.
