      abstract     = {We have implemented the computation of Coulomb interactions
                      in particle sys-tems using the performance portable C++
                      framework Kokkos. For the com-putation of the electrostatic
                      interactions in particle systems we used an Ewaldsummation.
                      This implementation we consider as a basis for a
                      performanceportability study. As target architectures we
                      used Intel CPUs, including In-tel Xeon Phi, as well as
                      Nvidia GPUs. To provide a measure for performanceportability
                      we compute the number of needed operations and required
                      cycles,i.e. runtime, and compare these with the measured
                      runtime. Results indicate asimilar quality of performance
                      portability on all investigated architectures.},
