Contents
A parallelization of a sweeping preconditioner for three-dimensional Helmholtz equations without large cavities is introduced and benchmarked for several challenging velocity models. The setup and application costs of the sequential preconditioner are shown to be $O(\gamma^2 N^{4/3})$ and $O(\gamma N \log N)$, where $\gamma(\omega)$ denotes the mod...
