英文摘要	As a crucial part of high-resolution waveform inversion and reverse time migration, seismic modeling demands a high efficiency of computation. The general-purpose GPU computing technology provides a fundamental basis as for GPU was naturally designed with data parallelism. By virtue of staggered-grid Fourier pseudo-spectral differentiation matrix operator, solving wave equation can be easily implemented on GPU by matrix multiplication. In large-scale two-dimensional wavefield computation, optimized single GPU forward seismic modeling can achieve at least 100x faster than that of single CPU using only one core. This high speedup GPU/CPU implementation enables us to quickly recognize seismic events of the reflectors of different layers in common shot profile, which is helpful for optimizing the acquisition configuration in field work.
