Performance portability is becoming more-and-more important as next-generation high performance computing systems grow increasingly diverse and heterogeneous. Several new approaches to parallel programming, such as SYCL and Kokkos, have been developed in recent years to tackle this challenge. While several studies have been published evaluating these new programming models, they have tended to focus on memory-bandwidth bound applications. In this paper we analyse the performance of what appear to be the most promising modern parallel programming models, on a diverse range of contemporary high-performance hardware, using a compute-bound molecular docking mini-app.
