2020 arXiv   pre-print
Simulations are carried out on industry scale synthetic models in a HPC Cloud system and reach a performance of 28TFLOP/s, hence demonstrating Devito's suitability for production-grade seismic inversion  ...  In this article, the generation and simulation of MPI-parallel propagators (along with their adjoints) for the pseudo-acoustic wave-equation in tilted transverse isotropic media and the elastic wave-equation  ...  Secondly, through the elastic modelling example, we demonstrate that Devito now fully supports and automates vectorial and second order tensorial staggered-grid finite-differences with the same high-level  ...
