- Abstract
- Although explicit time integration schemes require small computational efforts per time step, their efficiency is severely restricted by stability limits. In particular, unstructured meshes can lead to a very restrictive global stable time step. Multirate methods offer a way to increase the efficiency by gathering grid cells in appropriate groups. The parallelization of these schemes is challenging because grid cells have different workloads. We propose a strategy that shares the workload almost equitably between all processors at every multirate stage. Performance analyses are provided for ocean modeling applications.
