| Abstract: | First, this paper presents the properties and fundmental principles of RegCM model with high distinguishability from National Climate Center.On the basis of the analysis of its basic flow,its serial algorithm and the characteristics of algorithm,data flow ,we developed a parallel scheme according to the longitude partition.We also optimized its I/O and communication efficiently.After the implementation on Sunway MPP,we found that better performance could be got when running on 4 processors and the number of the processors could be extended to 16. |
