The acoustic isotropic assumption for wave propagation in the subsoil has limitations, which threat to hamper the results of modern day imaging tools, such as RTM or FWI. Elasticity and anisotropy bring us closer to the real physics of the propagating waves, although at a severe computational cost. Hence, we aim at solving 3D anisotropic elastic wave propagation problems in modern HPC platforms. We require our solutions to be sufficiently accurate, efficient and highly scalable for large-scale scenarios. This condition set leads us to use multi-GPU platforms and a variety of time-domain staggered-grid finite-difference (FD) schemes.
