Distributed -matrices for boundary element methods
Steffen Börm
Standard discretization techniques for boundary integral equations, e.g., the Galerkin boundary element method, lead to large densely populated matrices that require fast and effic…

Dielectric breakdown prediction with GPU-accelerated BEM
Cedric Münger, Steffen Börm, Jörg Ostrowski
The prediction of a dielectric breakdown in a high-voltage device is based on criteria that evaluate the electric field along field lines. Therefore it is necessary to efficiently…

Semi-Automatic Task Graph Construction for -Matrix Arithmetic
Steffen Börm, Sven Christophersen, Ronald Kriemann
A new method to construct task graphs for \mcH-matrix arithmetic is introduced, which uses the information associated with all tasks of the standard recursive \mcH-matrix algorithm…
