Abstract:High performance computing technology and industry have been developing and flourishing. From serving the only demand for peak performance of national strategic departments to serving market-driving, application promotion, and industrialization advancement, China's high performance computing has surpassed the three mountains of "breaking blockade", "breaking monopoly", and "leading innovation", gradually narrowing the gap with foreign advanced research and development level, and has achieved worldleading achievements in the design of the whole machine system and other key technologies. In this paper, we analyze the trend of the development of super-computer and the way of the development modes of Sugon super computer, then summarize the challenges of high-performance computers into two points:the sustainable construction of Exascale before the failure of Moore's law and the revolutionary technology of super-computer system in post-Moore's law era. In response to these challenges, the paper elaborates policy recommendations for "facing the world's scientific and technological frontiers, facing the country's major needs, and facing the national economy's main battlefield".
