Future computer systems are built under much stringent power budget due to the limitation of power delivery and cooling systems. To this end, sophisticated power management techniques are required. Power capping is a technique to limit the power consumption of a system to the predetermined level, and has been extensively studied in homogeneous systems. However, few studies about the power capping of CPU-GPU heterogeneous systems have been done yet. In this paper, the authors propose an efficient power capping technique through coordinating DVFS and task mapping in a single computing node equipped with GPUs.
