Abstract: Based on the data of China’s high performance computer TOP100 rankings published in November 2018,this paper made an in-depth analysis of the current development status of high performance computers in China from the overall performance,manufacturer,industry and other aspects.The average Linpack performance of TOP100 in China continues to be higher than that of the international TOP500,and the threshold for entry performance of TOP100 still exceeds that of TOP500.China’s supercomputing system on TOP100 has almost all been a domestic supercomputer system,and the Shuguang and Lenovo have become the champion on the number of systems on Top100.The situation of the three strong hegemony of Shuguang,Lenovo and Inspur continues to be maintained and strengthened.On the basis of this,according to the performance data of the seventeenth ranking list,this paper analyzed and predicted the development trend of high-performance computers in mainland China in the future.According to the new data,we believe that machines with peak Exa ops will appear between 2018 and 2019;machines with peaks of 10 Exa ops will appear between 2022 and 2023;machines with peaks of 100 Exa ops will appear between 2024 and 2025.
