MPI进程通信子动态重构的实现

Implementation of the Dynamic MPI Process Communicator Reconstruction

本文深入研究了MPICH的p4库通信机制及通信子结构,提出一种MPI通信子动态重构方法,实现了MPI 进程的动态加入,解决了MPI容错和进程迁移所涉及的新生成进程与已有进程间的通信问题。

This paper analyses and proposes a solution to the dynamic MPI communicator reconstruction, which permits a newly created MPI process to join an existing process group freely, and resolves the problem of the communications between the newly created processes and the existing processes in MPI fault tolerance and process migration.
