Optimizing RTM for Xeon Phi: Lessons Learned

In this presentation we will share our experience in porting and optimizing a commercial Reverse Time Migration (RTM) library to a cluster of Xeon Phi Coprocessors. The talk will focus on the different techniques needed to efficiently run real world data, as well as the similarities of optimizing a TTI propagation kernel for Xeon Phi and Xeon Sandy Bridge. The case study highlights the importance of fully utilizing the processing cores as well as the vector units within each core. We will demonstrate how parallel computation is obtained by tuning the OpenMP pragmas and the auto-vectorizer. Further speed improvements are obtained by implementing thread affinity for multi-tasking and fine tuning the memory access patterns for optimal data throughput. The second part of the presentation will focus on how to achieve linear scaling across multiple devices, which is critical when dealing with real-world RTM problems.
