Abstract

Co‐processors offer attractive acceleration opportunities to waveform‐based imaging and inversion applications in challenging exploration and production environments. Unlike seismic forward modeling, the large amount of data involved in seismic imaging and inversion can pose a significant challenge to scalable acceleration. We provide and compare several computational schemes to perform anisotropic reverse‐time migration on two co‐processor platforms: FPGAs and GPUs. Our ongoing experiments so far indicate that both platforms can potentially achieve high speedups using acceleration‐friendly schemes which minimize interruptions to computation from data movement and storage.
