摘要
提出两种不同级别透明MPI(Message Passing Interface)的概念和结构组成,分别从应用级透明和通信级透明两个层面来阐述提出透明MPI的动机,以及它们的具体架构和基于MPICH2的实现过程,并对其优缺点进行全面分析。通过测量发现,在单一系统映像的机群下,透明MPI不仅简单易用,还获得了性能上的提高。
We propose the concept and structure formation of message passing interface （MPI） in two different transparent levels, and expatiate on the motivation of presenting the transparent MPI from two Ieveis respectively, the application level transparency and the communication level transparency, as well as their specific architecture and the implementation process based on MPICH2, followed by the comprehensive analyses on their advantages and disadvantages. It is found from the measurement that the transparent MPI is simple and easy in use under the single system imaging computer cluster condition, and wins the improvement in performance.
