Pipeline Implementation of Waveform Relaxation Methods Ong, Benjamin


Recently several waveform relaxation algorithms have been proposed, where the standard Dirichlet or Robin coupling conditions are replaced by transmission conditions that are implemented in stages, for example the Dirichlet--Neumann coupling conditions. These new transmission conditions promise better rates of convergence at the expense, as it turns out, of parallel efficiency. This talk focuses on a practical implementation of these new waveform relaxation algorithms, as well as an analysis of the communication cost and efficiency overhead of these algorithms.
