A parallel AMG for overlapping and non-overlapping domain decomposition

Gundolf Haase


There exist several approaches for the parallel solving of huge systems of linear equations resulting from the finite element (f.e.) discretization of $2^{{\rm nd}}$ order elliptic pdes. On the other hand, there exists a great demand for Algebraic Multigrid solvers (AMG) which have as input only matrix and right hand side or, as a substitute, the appropriate information per element. In this paper we propose a general parallel AMG algorithm using overlapping or non-overlapping data decompositions.
