The Intel SCC manycore processor supports energy-efficient computing by dynamic voltage and frequency scaling of cores on a fine-grained level. In order to enable the use of that feature in application-level energy optimizations, we report on experiments to measure power consumption in different situations. We process those measurements by a least-squares error analysis to derive the parameters of popular models for power consumption which are used on an algorithmic level. Thus, we provide a link between the worlds of hardware and high-level algorithmics.
