Abstract :
In an HPC era attracting notice to energy efficiency, a promising performance per watt ratio motivates the usage of accelerators like GPGPUs or Intel´s Xeon Phi in today´s heterogeneous computer systems. However, these heterogeneous architectures often get far more complex to program and employ.
