Coupling Technique for Distributed High Performance Earth System Simulation Framework

摘要

The Earth system includes a mass of interactive physical elements which interact to cause the constant changing of the Earth, even disaster. Disaster prediction of this system is crucial, but the complexity of this system brings a great challenge to researchers. Distributed high performance Earth system simulation framework is designed to solve this problem on our previous work. This paper proposes an efficient coupling interaction technique for this framework based on PRMI (Parallel Remote Method Invocation). It could automatically implement a series of complex underlying heterogeneous physics data remapping including grid remapping and data parallel distribution remapping, and ultimately realize the process to process parallel communication between physics-model components directly with no third-party conversion tools. Experiment results showed that this coupling interaction technique has achieved desirable performance, and successfully realized the numerical simulation of the coronal mass ejections.
