Resumo

Parallelism is now a standard from the hardware standpoint considering the multicore nature of current processors and their vector processing feature. Beside somehow following Moore's Law and/or running faster, the design of multicore processors was also driven by energy concern. With an increasing number of cores per chip and wider SIMD capabilities, the question of how the corresponding parallelism is related to power consumption is important for energy-aware parallel implementation. The goal of this work is to provide from experimentation some basic insights on the power consumption pattern related to the aforementioned levels of parallelism including accelerated-computing with GPUs.
