Waveform relaxation with adaptive pipeline (Felix Kwok, Hong Kong)

11.12.2018 14:00

Waveform relaxation methods are domain decomposition methods for time dependent PDEs in which subdomain problems are posed in space and time. In this talk, we introduce temporal parallelism in these methods, with different processors working on different time windows. Because the convergence rate of the new method is independent of the overall time horizon length, we obtain significant speedup relative to sequential time-stepping. Numerical examples are presented to illustrate the effectiveness of our approach.
