Performance Analyses of Slice Based on MPI Cartesian Topology Structure
Jinmin Yang · Science Technology and Engineer · 2005
The thought of slice in MPI topology structure by analyzing topology structure and communication characters of MPI parallel processes is brougt forward,and realized the MPI library functions to slice in general network topology structure. From the experiment performance analyses based on Cartesian topology structure, the conclusion that the method of using slice communicator to communication is better than that of using original communicator is got.
