What is the fastest computing speed in the world today?

The fastest computing speed in the world today is the computer.

The fastest computer in the world is Tianhe-2 supercomputer, which is a supercomputer system developed by National University of Defense Technology. In terms of the optimal performance of double-precision floating-point operation, it ranks first with a peak calculation speed of 549 million times per second and a continuous calculation speed of 339 million times per second, making it the fastest supercomputer in the world.

In the list of the world's top 500 supercomputers published in 17 10 on October 2010, China Tianhe II won the championship for the fourth time in a row, nearly twice as fast as the second American Titan. From 2065438 to May 2005, the N-body numerical simulation of 3 trillion neutrinos and dark matter was successfully carried out on Tianhe-2, revealing the long evolution process after BIGBANG16 million years.

Tianhe No.2 and Yinhe No.2

Tianhe No.2 has been applied in biomedicine, new materials, engineering design and simulation analysis, weather forecast, smart city, e-commerce, cloud computing and big data, digital media, animation design and other fields, and will be widely used in big science, big engineering, information technology and other fields, providing important support for economic and social transformation and upgrading.

Tianhe-2 has gradually shown its talents in a series of big science and big projects related to the national economy and people's livelihood, such as life science, material science, atmospheric science, geophysics, universe, economics, large-scale genome assembly, gene sequencing and pollution control. In addition, the National Supercomputing Guangzhou Center actively promotes international exchanges and cooperation, and provides high-performance computing services for foreign research institutions by using Tianhe II.

The domestic C9 19 large passenger plane has carried out high-precision aerodynamic calculation of the external flow field with the help of Tianhe-2. Shanghai Institute of Pharmacology, China Academy of Sciences has carried out the binding affinity evaluation of 750,000 small molecular compounds, and completed the in vitro and in vivo activity evaluation of more than 600 drugs. Tianhe-2 has adapted Guangzhou e-government data management system and cloud disk storage system, and built an efficient and reliable bearing platform for smart city construction.
