| Abstract(in English) | This paper shows evaluation of GPU implementation Perfectly Matched Layer (PML) absorbing boundary condition for a 3-D FDTD method. Our previous implementation has a lot of invalid regions for padding because of unbalance between efficient blocking size for GPU and thin PML regions. This presses GPU memory usage and reduces the performance. We optimized the implementation of PML introducing the periodic boundary condition to cope with these problems. Our proposed method reduces about 49 % of memory usage and improves about 14 % of performance compared to our previously implementation, showing the effectiveness of the idea. |
