In this paper,firstly introduce the application of HPC in WHIHR and the current mode of business systems. For the better re-quirements of the weather forecasting model fine to computing ability,the institute of heavy rain of China Meteorological Administration uses the dawn of high-performance computer clusters to upgrade the original cluster system. The upgraded computing node can provide the 11. 40 TFlops double-precision floating-point computing power. Secondly,discuss the present status and the prospect of key technol-ogy of advanced HPC. Finally,taking WRF model as example,analyze the performance of HPC and have a good speedup. The result shows that the new upgraded cluster system would greatly reduce the computation time of regional high-resolution numerical weather pre-diction model. Also it could improve the conversion efficiency of scientific research.
