Towards supporting composability of directive-based programming models for heterogeneous computing

Current trends in High Performance Computing suggest a significant shift towards heterogeneous architectures, utilising GPUs and other accelerators for their combination of computation capacity and power efficiency. Therefore, programming heterogeneous applications becomes increasingly relevant. How...
