Increasing the parallelism in common azimuth migration with overlap domain decomposition
Sean E. Crawley · 2008
Common azimuth migration (COMAZ) is an efficient algorithm for generating wave equation quality images of narrow azimuth (in particular towed streamer) seismic data. The algorithm is naturally parallel over input frequency. We increase the parallelism of the algorithm using overlap domain decomposition to divide the spatial axes of the data.
