Gpu-based Calculation of Trajectory Similarities

Graphics Processing Units (GPUs) are more and more used for general purpose calculations. In the area of modeling and simulation, GPU’s calculations are typically associated with executing specific simulation models. Besides this application, we propose the use of GPUs not only in the context of model execution but also to analyze simulation results, e.g., to compute the similarity of simulation trajectories. We present initial evaluation results from using the GPU for such applications and discuss opportunities, challenges, and pitfalls. We conclude with further possibilities as well as some future directions for leveraging the GPU for different analyzing tasks in the field of modeling and simulation.
