Abstract

The large-scale simulation of the electromagnetic wave propagation using meshless time domain method (MTDM) is numerically investigated. Moreover, compute unified device architecture (CUDA) and OpenMP is adopted for parallelization technique to reduce the computation time. The results of computation show that the execution time of the time evolution calculation on GPU is 8.8 time faster than that of CPU. In addition, the execution time of the shape function generation procedure can be speedup about 7842 times by proposed scheme and OpenMP.
