Open publisher page 0 citations

Abstract

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.
