                      2023 three different GPU (Graphics Processing Unit) vendors
                      are represented in the top 10 of the list. Each vendor has
                      its own preferred model for programming GPUs. For this paper
                      we implemented the N-body problem using portable programming
                      frameworks and the vendors’ preferred APIs. We show how
                      the performance of the portable solutions compares to the
                      performance of the native solution on each hardware both in
                      absolute numbers and as fraction of the achievable peak
                      performance.},
