      abstract     = {Since Aurora entered the TOP500 list in November 2023, the
                      top ten systems saw some shifts in the ratio of GPU vendors
                      represented. With each vendor supplying their own preferred
                      programming models for their hardware, it becomes relevant
                      to compare the portability of these models on other hardware
                      platforms. For the present paper we implemented the N-body
                      problem with different optimizations using native and
                      portable programming frameworks. For each of those we
                      determined the best performing optimized version on one
                      target architecture and compared the performance achieved
                      for each platform.},
