This method can also be used to accelerate reverse time migration algorithms and full waveform inversion. The absorb boundary conditions used in the method are based on the Perfectly Matched Layer (PML) strategy. The GPU devices accelerate the alternating iterative process between velocity and stress. With the help of the optimized CUDA code on GPU, the computing speed of 3D modeling problems accelerated obviously. The results show a speedup of approximately 60x in the GPU implementation than in the Intel CPU. Therefor this method can be applied in industrial production.
