HPC Implementations on SEM46: A 3D Modeling and Inversion Code for Anisotropic Visco-Elastic Coupled Acoustic Media

Résumé

Main objectives A 3D modeling and inversion code named SEM46 has been developed since few years in the SEISCOPE project. Currently this code implements a coupled visco-elastic/acoustic wave propagation, with generic types of anisotropy in the solid part. For practical usage, such 3D modeling and inversion code needs to be able to exploit efficiently the performance of modern large scale computing facilities. This study aims at presenting the recent HPC implementations and performance optimizations done on this code to achieve this goal. New aspects covered (1) Presentation of several optimizations and quantification of the performance gains. (2) New porting on the TGCC center (AMD Rome partition) and new parallel efficiency assessed to compare acoustic, elastic and acoustic-elastic coupling modeling.
