Summary:
We present a multilevel parallel algorithm for migration of seismic data based on the solution of one-wave wave equation. Wavefield extrapolation is performed by using pseudo-spectral method, thus the main computational effort is to perform forward and backward FFT which is done by use of GPU. Parallel data processing implemented in the algorithms allows computing common-offset common-angle gathers for multi-source seismic data
