Abstract

Summary

Reverse Time Migration (RTM) is the seismic imaging everyday tool. Traditionally, it is implemented with finite differences method, which is at its core a stencil computation. Stencil computations pose major challenges for all major processor architectures with their deep memory hierarchies. In this work, a novel RTM algorithm is presented. It efficiently exploits extreme scale distributed-memory platforms with no cache hierarchy, a paradigm closer to dataflow rather than traditional von Neumann architecture. The implementation following this paradigm delivers disruptive level performance.
