Digital hologram generation methods commonly use computer generated hologram (CGH) algorithm. However, it requires complicated computation. Thus, this paper proposes an optimization method for a fast generation of digital hologram. The proposed method uses CUDA and OpenMP for multi-GPU. Also, it applies various optimization methods (variable fixation, vectorization, and loop unrolling) to a CGH algorithm. We verify the effectiveness of our optimization method through a variety of experiment.
