  Design and Implementation of Generic Solver Components
Peter Bastian (Univ. Heidelberg)

(joint work with Markus Blatt)

In the first part of this talk we show that generic programming represents a significant break-through in the design and implementation of scientific computing applications. Algorithms are formulated in a generic way based on abstract interfaces without any performance penalty while allowing the reuse of existing code. We demonstrate these techniques with the mesh and linear algebra interfaces which are implemented in the "Distributed and Unified Numerics Environment" (DUNE) that is currently being developed together with groups in Berlin and Freiburg. In the second part of this talk we apply these techniques to a parallel implementation of an algebraic multigrid method. Robustness and speedups for model problems in two and three space dimensions are demonstrated for up to several hundred processors.
