China’s first supercomputer capable of 100 million calculations per second was the YH-1,which was independently developed by the Institute of Computer Science at the National University of Defense Technology(NUDT)between 1978 and 1983.YH-1 played an important role in China’s national defense construction and national economic development.It made China one of the few countries in the world to successfully develop a supercomputer.Based on original archive documents,interviews with relevant personnel,and an analysis of the technological parameters of the supercomputers YH-1 in China and Cray-1 in the United States,this paper reviews in detail the historic process of the development of YH-1,analyzing its innovation and summarizing the experience and lessons learned from it.This analysis is significant for current military-civilian integration,and the commercialization of university research findings in China.
