AB  - The simulation of long-range electrostatic interactions in huge particle ensembles is a vital issue in current scientific research. The Fast Multipole Method (FMM) is able to compute those Coulomb interactions with extraordinary speed and controlled precision. A key part of this method are its shifting operators, which usually exhibit O(p^4) complexity. Some special rotation-based operators with O(p^3) complexity can be used instead. However, they are still computationally expensive. Here we report on the parallelization of those operators that have been implemented for a GPU cluster to speed up the FMM calculations.
