文摘

An open source software for viscoelastic full waveform inversion is presented. This software is based on OpenCL and can run on CPUs, GPUs and accelerators. On large clusters, MPI is used and a nearly linear scaling is achieved. Using GPUs, we obtain a speed-up of up to 80x over a single threaded CPU code.
