Abstract

A networked system includes a computing device having a central processing system and accelerator system(s). A central processor/accelerator power management system coupled to the computing device via a network operates to deploy workload(s) on the computing device and receive workload performance information from the computing device that identifies a central processing system utilization of the central processing system in performing the workload(s) and an accelerator system utilization of each accelerator system in performing the workload(s). Based on the workload performance information, the computing device determines a first power consumption ratio of the central processing system and the accelerator system(s) in performing the workload(s), and modifies operation of at least one of the central processing system and the accelerator system(s) to change the first power consumption ratio to a second power consumption ratio that is more power efficient than the first power consumption ratio.
