| Abstract(in English) | In this study, the finite-difference time-domain (FDTD) method has been accelerated by CPU cluster with 64 CPUs (NVIDIA Tesla K20m), and we have applied to large-scale and realistic electromagnetic simulations, such as ground penetrating radar (GPR) and analysis of lightning electromagnetic filed. We have obtained the performance of floating-point operations of the FDTD method for single and double precision in 6.2 Tflops and 3.7 Tflops, respectively. It is shown that large-scale and realistic GPR simulation for searching reinforcing bar using FDTD method with 64 GPUs can be calculated in about 30 minutes, and analysis of lightning electromagnetic filed with numerical terrain model using moving-window FDTD (MW-FDTD) method with 48 GPUs can be calculated in about I minute. |
