Date: July 25 - 29, 2011

Venue:

Lectures: HIM lecture hall, Poppelsdorfer Allee 45

Exercises: Institut für Numerische Simulation, Wegelerstr. 6

Speakers: Wolfgang Hackbusch (Leipzig), Steffen Börm (Kiel), Lars Grasedyck (Aachen)

Hierarchical Matrices can be a useful tool for the treatment of integral operators as well as the solution of linear systems arising in the discretization of elliptic partial differential equations. Moreover, the representation of matrices in the hierarchical matrix format is suitable for the efficient solution of matrix equations. This school teached the necessary theoretical foundations for hierarchical matrices, but most of all the efficient implementation of the algorithms. The practical realization on the computer was done during the exercise courses in the afternoons. The participants used the HLib library in order to assemble and solve BEM and FEM systems.
