Dan Fei Huang · Journal of Changchun Normal University · 2007
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.
