Abstract :
Based on the message passing interface (MPI) implement of parallel FDTD, this paper puts forward a more efficient mechanism, which decreases the time of communication and synchronization so as to enhance the efficiency of parallel FDTD. The efficient mechanism mainly consists of overlapping model and logic layer model. In addition, this paper also analyzes the performance gain in various network environments. Meanwhile the mechanism reduces the interdependence between processes so that expanding parallel FDTD into grid computing (Foster et al., 2003) environment is feasible.
