Abstract: In the background of study on activity regularity of the sun-earth system, this paper proposes an efficient multi-physics coupling interaction mechanism PRMI++ for sun-earth system based on SCIRUN group’s PRMI with four-point improvement. It can automatically accomplish gird re-mapping and parallel distribution re-mapping of data when the physical model components on the parallel remote method invocation to achieve coupling interactions. Experimental results prove PRMI++ has better performance.

Key words: sun-earth system, multi-physics coupling, parallel distribution re-mapping, gird re-mapping

摘要： 以日地系统活动规律研究为背景，通过对SCIRUN提出的PRMI进行4点改进，提出一种高效的日地系统多物理耦合交互机制PRMI++，能够在物理模型组件进行并行远程方法调用实现耦合交互的同时，自动实现网格重映射和数据并行分布重映射。实验结果证明PRMI++具有较好的性能。
