On this day, 27 years ago, on October 5, 1998 (August 15, 1998, the "Galaxy III" supercomputer was equipped with troops for the first time. The "Yinhe III" supercomputer is equipped with troops for the first time, and our military meteorological support capabilities have been improved. After three days of strict testing and nearly 10 days of smooth operation, the "Yinhe III" parallel supercomputer has demonstrated excellent performance in the numerical prediction business of the General Staff Department Meteorological Center. The responsible comrades of the relevant departments of the General Staff Department announced on October 5, 1998 that this is the first time that the "Galaxy-III" supercomputer has been equipped with troops. It is of extraordinary significance to improving our military's military meteorological support capabilities and modernization level. The "Galaxy-III" supercomputer was successfully developed in September last year, with a peak computing speed of 13 billion calculations per second. Due to sufficient preparations in terms of application software development and software and hardware running-in, the "Yinhe-III" was successfully launched in just over a day to assemble. It was seamlessly connected with the "Military Numerical Weather Forecasting System", a key meteorological project of the entire army during the Ninth Five-Year Plan. The actual computing speed greatly exceeded the indicators when the "Yinhe-III" passed the appraisal. "From 'birth' to 'emergence','Galaxy-III' has grown into a beautiful big girl. Yang Xuejun, chief designer of "Galaxy-III", expressed satisfaction with the performance of the machine. He said that "Yinhe-III" is currently the highest performance computer used by domestic meteorological operations departments. Medium-and long-term numerical forecasting requires extremely high computer computing speed. A more complex numerical prediction model to produce a 10-day forecast requires continuous operation for 12 days on a million-time computer, but only two hours on a billion-time computer. According to reports, running numerical weather prediction system software on parallel computers is a development trend in the field of world meteorological applications and a worldwide problem. The parallel meteorological application software developed by the National University of Defense Technology and the Meteorological Department of the General Staff Headquarters has been put into practical use on distributed storage parallel computers for the first time among similar domestic software, ranking a leading position in the country and reaching the current international advanced level. Relevant people called it a "milestone event" in military weather. In addition to better meeting the requirements of numerical prediction in terms of computing speed indicators,"Yinhe-III" has adopted a new model of synchronous cooperation with users during the development process, which has greatly shortened the development cycle of numerical prediction operational application software.
