On decreasing the calculation time in three-dimensional acoustic numerical simulation by multi-gpu parallel computing

Numerical analysis for sound wave propagation in time domain has been investigated widely as a result of computer development. The finite difference time domain (FDTD) method is the most popular scheme used in acoustics. In the past study, the authors have proposed an acoustic simulation technique using generalized constrained interpolation profile method (GCIP method). When we analyze large-scale sound wave propagation, the reduction of the calculation time is a necessary requirement. Recently, GPU (Graphic Processing Unit) is used as an acceleration tool for the calculation in various study fields. This study makes an examination on decreasing the calculation time in three-dimensional acoustic field numerical analysis using GPU
