Chinese supercomputers return to the top of the world, how high is their significance?

After 9 years, China's supercomputer returns to the world's number one spot! At a recent international supercomputing conference, the Shenzhen National Supercomputing Center unveiled the new generation "Ling Shi" supercomputing system, with a measured sustained performance of 2.19EFLOPS, making it the world's first supercomputer system with sustained performance exceeding 2EFLOPS. This "return to the top" marks China's return to the global number one ranking in supercomputing since the "Sunway TaihuLight" in 2017. In the past, many key technological products in the supercomputing field relied on imports, which to some extent constrained the high-quality development of China's computing power field. This top-ranking supercomputing system achieves full-stack localization of key components, marking a significant step towards independent research and development, independent iteration, and leading development in China's supercomputing industry. In the increasingly fierce global technological competition, key core technologies cannot be bought, begged, or borrowed, and only independent innovation can grasp the initiative in development. The significance of China's return to the world's number one spot in supercomputing lies in the increasingly strong independent controllable capabilities in the high-tech field.
