What is the Galaxy II computer designed and developed by our country?

The Galaxy II computer designed and developed by our country is a supercomputer.

The Galaxy II supercomputer was successfully developed by the National University of Defense Technology and the National Meteorological Center. With 1 billion operations per second, its emergence has made China one of the few countries in the world that can issue medium-term numerical forecasts.

"Galaxy" computer series

• Galaxy-Ⅰ

##In November 1983, my country The first billion-time giant electronic computer named "Galaxy" was born at the National University of Defense Technology after five years. Its successful development announced to the world that China has become a country that can independently design and manufacture supercomputers after the United States, Japan and other countries.

• Galaxy-III

On June 19, 1997, the "Galaxy-III" parallel supercomputer developed by the National University of Defense Technology passed the test in Beijing National identification. The machine adopts a distributed shared storage structure and is oriented to large-scale scientific and engineering calculations and large-scale data processing. The basic word length is 64 bits and the peak performance is 13 billion times. This machine has many technologies that are domestically leading, and its comprehensive technology has reached the current international advanced level.

After the "Galaxy" computer was successfully developed, the China Electronic Computer and Large Scale Integrated Circuit Leading Group organized 95 computer experts and engineering technicians from 29 units across the country to establish the "Galaxy Computer National Technical Appraisal Group". And they were divided into seven groups to conduct a comprehensive and strict technical assessment of the "Galaxy" aircraft.

The results show that: 26 correctness test questions that are widely representative in national economic development and scientific research have been calculated three times, the data are exactly the same, the results are correct, and the accuracy meets the requirements; under single-channel operating system control The whole system and host are stable and reliable; the hardware system vector calculation speed reaches more than 100 million times per second; the software system is rich in content, strong in functions, easy to use, advanced in performance, and has complete drawings and materials.

Significance

The successful development of the "Yinhe" aircraft will have great impact on China's petroleum and geological exploration, medium and long-term weather numerical forecasting, satellite image processing, calculation of large-scale scientific research projects and national defense Construction plays an important role.
