The method of Support Operator(SOM) is a numerical method based on finite difference method. We use SOM to simulate seismic wave propagation by solving the three dimension viscoelastic equations. The Support Operator Rupture Dynamics(SORD) has been proved to be highly scalable in large-scale multi-processors computing. This paper discusses accelerating SORD on multi-GPU system using NVIDIA CUDA C and MPI. Compared to its original version on multi-CPU system, we have achieved a maximum 15.0X speed-up.
