Abstract
As HPC systems increase in scale and capability, the cost of supplying power to these systems grows significantly. This introduces the urgent need for energy efficient computing through the management of power consumption. The PowerStack initiative defines a holistic power management framework at three levels, i.e., at the cluster level, the job level, and the node level [1] –[3]. It is expected that a cluster will be given a system-wide power budget (aka an allocated power budget), which can be intelligently managed and distributed at the job and node levels. Our work provides a method for intelligently managing node-level power during execution.
