Heterogeneous HPC architectures are becoming increasingly prevalent in the Top500 list with CPU-based nodes being enhanced by accelerators or coprocessors optimized for floating-point calculations. This trend is likely to increase as we move towards Exascale (1018 flops) capable systems and it is vital that the relevant HPC applications are able to exploit this heterogeneity [1, 2].
