Abstract: Various embodiments are generally directed to an apparatus, method and other techniques to send a power operation initiation indication to the accelerator device via the subset of the plurality of interconnects, the power operation initiation indication to indicate a power operation to be performed on one or more infrastructure devices, receive a response the accelerator device, the response to indicate to the processor that the accelerator is ready for the power operation, and ucause the power operation to be performed on the accelerator device, the power operation to enable or disable power for the one or more of the infrastructure devices.

Abstract: A local power control arbiter is provided to interface with a global power control unit of a processing platform having a plurality of processing entities. The local power control arbiter controls a local processing unit of the processing platform. The local power arbiter has an interface to receive from the global power control unit, a local performance limit allocated to the local processing unit depending on a global power control evaluation and processing circuitry to determine any change to one or more processing conditions prevailing in the local processing unit on a timescale shorter than a duration for which the local performance limit is applied to the local processing unit by the global power control unit and to select a performance level for the local processing unit depending on both the local performance limit and the determined change, if any, to the prevailing processing conditions on the local processing unit.
