MPI环境下基于边界校正方法的海洋模型的并行化
符晓单1, 李洪平1
中国海洋大学 信息科学与工程学院
摘要:
基于区域分解技术, 设计了一种针对海洋模型的边界校正方法, 该方法不需要对原有海洋模型进行较大改动, 只需要利用消息传递接口(message passing interface, MPI)编写子区域间的数据传输模块, 即可实现原有海洋模型的并行化。相对于重新开发并行系统, 该方法能够较快把原有模型的串行解决方案转化为并行解决方案, 并且并行化后的海洋模型能够获得较高的加速比。

A boundary correction method for the parallelization of ocean model under MPI environment
Abstract:
Based on domain decomposition, this paper proposes a parallel technology for ocean model, and this technology doesn’t need many changes of the original ocean model, which can parallelize the original ocean model only by using MPI basic functions to construct data transmission module between sub-domains. Relative to redevelopment of a new parallel system, the parallel technology can quickly transform the serial solution of the original model into parallel solution, and the parallel version of the ocean model can get a higher speedup.
Key words:  boundary correction  parallelization  domain decomposition  MPI(message passing interface)
