Abstract
We introduce the time-parallel compound wavelet matrix method (tpCWM) for modeling
the temporal evolution of multiscale and multiphysics systems. The method couples time
parallel (TP) and CWM methods operating at different spatial and temporal scales. We
demonstrate the efficiency of our approach on two examples: a chemical reaction kinetic
system and a non-linear predator–prey system. Our results indicate that the tpCWM technique
is capable of accelerating time-to-solution by 2–3-orders of magnitude and is amenable
to efficient parallel implementation.
