VALU, AVX and GPU Acceleration Techniques for Parallel FDTD Methods — Recommend this title to your library

Thank you

Your recommendation has been sent to your librarian.

In this chapter, we apply the FDTD method advanced by the parallel processing and SSE acceleration techniques [1-9] in solutions to a variety of practical engineering problems and demonstrate its advantages over other electromagnetic simulation techniques. We first introduce the hardware platform configuration and then apply the parallel FDTD code enhanced by the SSE technique to solve the problems. The performance of VALU acceleration is associated not only with the hardware configuration and code structure but also with the problem model, excitation type, and output options. The parallel FDTD code used in this chapter has been optimized for the best performance in terms of the VALU acceleration, mesh generation, model handling, excitation, and output processing. The examples include a helix antenna array, dielectric lens, electromagnetic analysis of an automobile and a helicopter, finite-sized frequency selective surface (FSS), curved FSS, microwave filter, reverberation chamber, airplane wireless fidelity (WIFI) analysis, low-pass filter, microwave divider, and waveguide slot antenna array.
