Explore a 20-minute conference talk from JuliaCon 2024 that introduces SeismicWaves.jl, a powerful wave simulation package designed for Full Waveform Inversion (FWI) applications. Learn about the package's implementation of finite-difference methods for solving wave equations in parallel and distributed systems, leveraging ParallelStencil.jl and ImplicitGlobalGrid.jl for seamless multi-xPU computing capabilities. Discover how rigorous benchmarks demonstrate the solvers' accuracy while achieving impressive memory throughput of up to 90% peak performance on modern GPUs and strong weak scaling on distributed systems. Understand how this package bridges the gap between theoretical concepts and practical applications in FWI, offering versatile solutions for both rapid prototyping on laptops and large-scale, high-resolution simulations on supercomputing clusters.
