对采用无网格时域法（MTDM）进行大尺度电磁波传播模拟进行了数值研究。采用CUDA计算统一设备架构和OpenMP并行化技术，减少了计算时间。计算结果表明，时间演化计算在GPU上的执行速度比CPU快8.8倍。此外，该方案可将形状函数生成过程的执行时间提高约7842倍。
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.
