摘要

本文研究了一种新的时域有限差分法的加速技术，该技术采用了新的Intel指令扩展——Intel Advanced Vector extensions (AVX)。我们比较了FDTD算法的两种配置(一种启用AVX，另一种不启用AVX)，并给出了两种设置的性能演变。数值结果表明，带AVX的时域有限差分法比不带AVX的时域有限差分法具有7倍以上的加速比。

Performance study of AVX instructions for the FDTD method

This paper studies a novel acceleration technique for the FDTD method using new Intel instruction extensions - Intel Advanced Vector Extensions (AVX). We compare two configurations of FDTD algorithm (one enabled with AVX and a second without AVX) and present a performance evolution of the two settings. The numerical results show that the FDTD with AVX gives over 7 times speedup ratio compared to the FDTD without AVX.
