摘要
In the light of the function and characteristics of the Dawning-1000 paral- lel computer made in China, we designed the parallel calculation scheme of the MM4 mesoscale numerical model. Because of the technological processing and meticulously remaking of the data organization and program flow of the sequential program, it reaches reliable calculation results and the SPEEDUP ratio rises obviously at last. When sixteen processing nodes are used, the SPEEDUP ratio reaches 1:6.7. In finite region, the model needs only less than 30 minutes to integrate 36 hours, and the operational parallel calculation environment for application of MM4 mesoscale model is preliminarily set up.
