Study on High Performance of MPI-Based Parallel FDTD from WorkStation to Super Computer Platform

Parallel FDTD method is applied to analyze the electromagnetic problems of the electrically large targets on super computer. It is well known that the more the number of processors the less computing time consumed. Nevertheless, with the same number of processors, computing efficiency is affected by...
