A computing device, a method and a system to control power. The computing device is configured to be used as part of a network fabric including a plurality of nodes and a plurality of pooled accelerators coupled to the nodes. The computing device includes: a memory storing instructions; and processing circuitry configured to perform the instructions. The processing circuitry is to receive respective requests from respective ones of the plurality of nodes, the requests addressed to a plurality of corresponding accelerators, each of the respective requests including information on a kernel to be executed by a corresponding accelerator, on the corresponding accelerator, and on a performance target for execution of the kernel. The processing circuitry is further to, based on the information in said each of the respective requests, control a power supply to the corresponding accelerator.
