Abstract: As an indispensable support for knowledge and technological innovation,high-performance computing(HPC) is an important component for scientific and technological innovation system.In the new era,being an alternative way of scientific research,it is equally important as theories and experiments.In the past thirty years,HPC has achieved magic improvement,and has entered the era of exascale computing.China has achieved remarkable development in HPC,and has achieved a series of achievements represented by Tianhe,Sunway,and Dawning.China's high-performance system development level ranks among the top international ranks.Performance gains through semiconductor miniaturization is challenging after Moore's law ends.In the post-Moore era,improvements in computing power,opportunities for growth in computing performance will increasingly come from technologies from software,algorithms,and hardware architecture.Meanwhile,there are still many deficiencies in the development of HPC standards.This paper analyzes the current status and development trends of HPC technology and standards,analyzes the state-of-art of the current HPC standards,and proposes the necessity and importance of developing national HPC standards.
