Automatic OpenCL device characterization : guiding optimized kernel design

<02>This paper significantly advances our understanding of the pressing issue of how to obtain performance from many different heterogeneous devices, all of which require different programming styles for high performance. The paper breaks new ground in attacking this problem by automatically characterising devices via probing and testing using custom micro-benchmarks, and automatically giving the programmer advice as to how to optimise across a variety of platforms, and leading to significant improvement over state-of-the-art. This work has lead to further research in performance prediction for heterogeneous devices. EuroPar is a highly regarded conference, with generally low acceptance rates.
