Abstract:

An implementation of the multilevel Fast Multipole method for time harmonic electromagnetic computations is presented. The method is parallelized for shared memory machines. A new parallelization scheme which is a hybrid between previous methods is proposed. Several symmetries and other methods that reduce the storage requirement are proposed. The most important symmetry is for the translation operators. A method for reducing the CPU-time in the interpolation is also proposed.
