Reverse Time Migration Seg Wiki This poster de scribes our experiences of applying rice university’s hpctoolkit and hardware performance counters to gain insight into an mpi openmp code that performs reverse time migration (rtm) on a cluster of multicore processors. Hpctoolkit correlates such metrics with the program’s source code, works with multilingual, fully optimized binaries, has very low measurement overhead, and scales to large parallel systems.
Reverse Time Migration 1 At Main Wwj337 Reverse Time Migration Github Hpctoolkit works with multilingual, fully optimized applications that are statically or dynamically linked. hpctoolkit is designed for use on large parallel systems. Thanks to hpctoolkit's support for profiling hardware counters, such techniques can easily be evaluated with no manual bookkeeping whatsoever by the developer. further, it can also help determine the impact of these changes on different architectures. Hpctoolkit set of tools for measurement, analysis, attribution, and presentation of application performance for sequential and parallel (multi threaded and message passing) programs. We demonstrate hpctoolkit's utility by applying it to two scidac applications: the s3d code for simulation of turbulent combustion and the mfdn code for ab initio calculations of microscopic structure of nuclei.

This poster describes our experiences of applying rice university's hpctoolkit and hardware performance counters to gain insight into an mpi openmp code that performs reverse time migration. What can we do? trace call path samples. amd: pc sampling coming soon! want some help?. A unique capability of hpctoolkit is its ability to unwind the call stack of a thread executing highly optimized code to attribute time, hardware counter metrics, as well as software metrics (e.g., context switches) to a full calling context. In this work we will describe a method to automatically select the optimal number of nodes and the best domain decomposition for each shot in a rtm project.
