SeismicWaves.jl: a wave simulation package for FWI on multi-xPUs by Giacomo Aloisi PreTalx: https://pretalx.com/juliacon2024/talk... Presentation Slides: https://pretalx.com/media/juliacon202... The package is based on finite-difference methods for solving the wave equation in parallel and distributed systems using [ParallelStencil.jl](https://github.com/omlins/ParallelSte...) and [ImplicitGlobalGrid.jl](https://github.com/eth-cscs/ImplicitG..., enabling seamless multi-xPU computing. Rigorous benchmarks and synthetic inversions validate the solvers' correctness while achieving high memory throughput (up to 90% of peak) on modern GPUs and exhibiting good weak scaling on distributed systems. In conclusion, [SeismicWaves.jl](https://gitlab.com/JuliaGeoph/Seismic...) provides easy-to-use and efficient solvers to bridge the gap between theory and practice for a variety of FWI applications and use cases, from fast prototyping on a laptop to high-resolution, large-scale simulations on supercomputing clusters.
