Exascale systems will present programmers with many challenges. We review the parallel programming models that are appropriate for such systems and the challenges that implementations of those models face on an exascale system. We discuss the feasibility of using existing programming systems, thus preserving the investment in legacy applications, as well as the benefits and likelihood of new programming models and systems. We conclude with a discussion of pragmatic issues in the implementation of programming models and their use on an exscale system.
