General-purpose computing on graphics processing units (GPGPU) is a fast developing method of high performance computing (HPC). In some cases even a low-end video card can be several to dozens times faster than a modem CPU core. Seismic wave filed modeling is one of the problems of this kind. But in some modern methods of seismic exploration or seismology it is possible that hundreds of thousands of forward modelings are needed for final solution of the computational problem. Using mulit-GPU and hybrid CPU-GPU computations in distributed computer environments seems to be a natural next step in development of these method of HPC.
