Parallel computing architectures are becoming more complex with increasing core counts and more heterogeneous architectures. However, the most commonly used programming models, C/C++ with MPI and/or OpenMP, make it very difficult to write source code that is easily tuned for many targets. Newer language approaches attempt to ease this burden by providing optimization features such as computation and communication overlap, message-driven execution, automatic load balancing and implicit data layout optimizations. In this paper, we compare multiple implementations of LULESH, a proxy application for a shock hydrodynamics, to determine strengths and weaknesses of four traditional (OpenMP, MPI, MPI+OpenMP, CUDA) and four emerging (Chapel, Charm++, Liszt, Loci) programming models for parallel computation. In evaluating these programming models, we focus on programmer productivity, performance and ease of applying optimizations.
