Abstract

Summary

In this work, authors propose an open-source solution for the seismic stacking method with support to multi-GPU nodes and computational clouds. Three traveltime models are supported by default, namely Common Midpoint, Zero Offset Common Reflection Surface and Offset Continuation Trajectory. Future integrations with other computing technologies and/or models are also possible due to the solution’s extensible software architecture. Authors also propose and discuss a heuristic to improve the trace selection for the Offset Continuation Trajectory model. Finally, this article presents the performance gains obtained by the proposed heuristic and the scalability results got from the four distinct multi-node execution scenarios in the AWS computational cloud.
