The concept of this project is to enable productive optimization of parallel heterogeneous systems by providing rapid energy and performance feedback to the software developer, hardware developer (architect or SoC designer), runtime system, and compiler. The objectives are to 1) develop efficient low-overhead techniques for capturing architecturally-independent application profiles, and 2) to use this data to rapidly and accurately model power and performance across a wide range of heterogeneous system parameters. Critically, our modelling approach will provide insight into the source of inefficiencies by going beyond simple power and performance metrics to answer the real question of "why." These techniques will form the core capabilities needed to leverage increasingly heterogeneous systems in the era of Dark Silicon, across the spectrum of hardware, software, runtime, and compiler designers.
