摘要
MPICH是一种重要的MPI实现,其提供的通信函数对于并行程序的性能有很大影响。论文讨论了MPI消息传递机制,详细分析了标准通信模式下MPICH消息传递的分层结构、传输接口以及消息数据发送和接收过程中的数据拷贝和队列管理的实现方法,并给出了分析结果。
MPICH is an important implement of MPI. Its communication functions have significant influence to the performance of parallel program. This paper discusses communication mechanism for MPI, analyses particularly the MPICH' s hierarchical structure of message passing, interface of transmission, the methods of data - copy and queue - management during messages' sending and receiving in the standard communication mode. In the end, it shows the analytic results.
