It＇s one of the main applications of high performance eomputing（HPC）. With the development of HPC, the scale of the high performance computers is expanded rapidly. The peak performance of computers increases in a continuous and rapid way. But the sustained performance achieved by the real applications does not increase in the same scale as the peak performance does. As the computer architectures and program structures are becoming much more complex, more and more factors may affect the performance of programs. Combined with the real me- teorological numerical model, the technical research work of effective performance evaluation to high per- formance computing system has more and more important guiding significance of each stage in system＇s procurement, installation and performance optimization. In order to promote the ability of dealing with climate change science and technology support, China Meteorological Administration starts a new generation of national meteorological high performance compu- ting power construction. The high performance computing system performance evaluation technology re- search during this period is carried out. The computing features of meteorological numerical models and its demand for high performance com- puting systems are analyzed in detail. Combined with the existing high performance computing system ar- chitectures and the attributes of software and hardware, the performance evaluation scheme of high per- formance computing system is proposed. Adopting the actual measurement, benchmark test and evaluation model methods, the comprehensive performance test of high performance computing system is carried out. The test is divided into two stages. In system selection stage, the evaluation model method and benchmark test method are used. In the system installation and debugging stage, the actual measurement metho
