This abstract first appeared for US patent application 18490622 titled 'MECHANISM FOR FINE-GRAINED DEVICE POWER ATTRIBUTION TO SOFTWARE ENTITIES
Original Abstract Submitted
An integrated circuit (IC) device with capability to finely determine power attributions to software entities is disclosed. During each digital power meter (DPM) interval, and for each virtual machine (VM) (e.g., an instantiation of a software entity), power consumed by the cores, memory, and/or IO ports of the compute node in executing that VM may be determined. The power attribution information may be provided to higher level profilers so that over-subscription of power can be avoided. The power attribution information may be gathered without using cycles of the cores of the compute node.
