Accelerated Computing: "Reverse Time Migration: A Case Study of GPU/CPU Hybrid Computing," Scott Quiring, Acceleware Ltd


Watch the video


Reverse Time Migration (RTM) is now the dominant imaging technique used in deep marine seismic exploration. This commercial case study highlights the need for the implementation to be continuously re-balanced as hardware performance and software features evolve over time in order to avoid performance bottlenecks and maintain optimum throughput. The basic methodology of RTM and the computational challenges it raises will be shown, and a solution that takes full advantage of the resources available on a GPU / CPU hybrid compute node will be presented.

There are two major computational challenges in RTM: efficient propagation of a 3D seismic wavefield and accessing the wavefield in reverse-time order.
