Hierarchical Matrix Techniques for a Domain Decomposition Algorithm

Jeffrey Ovall


In this paper we investigate the effectiveness of hierarchical matrix techniques when used as the linear solver in a certain domain decomposition algorithm. In particular, we provide a direct performance comparison between an algebraic multigrid solver and a hierarchical matrix solver based on nested dissection clustering within the software package PLTMG.
