| Abstract: | When using FDTD(Finite Difference Time Domain Method) to simulate electric-large or complex configuration objects,there exist two challenges: costing too much computer time and memory.The parallel computation is an effective method to meet the challenges.Some key steps of the parallel FDTD such as space decomposition,data exchange between neighbor subdomains,array operation and processes synchronization,was studied and optimized.A FDTD parallelization scheme employing MPI(Message Passing Interface) library ... |
