Abstract
Fast boundary integration methods are implemented to increase the efficiency of the calculation of the magnetostatic interaction of magnetic particles. We test the treecode algorithm and a hierarchical matrices method to improve the original used matrix-vector multiplication with a fully populated matrix. We compare the CPU-time used for the setup phase and for the matrix-vector multiplication, as well as the required storage.
