Abstract:
1. A computer-implemented method for optimizing power consumption of an executing processor, said method comprising: a computer determining a first sensitivity relationship based on a first performance metric value corresponding to a first operating frequency of the processor and a second performance metric value corresponding to a second operating frequency of the processor, wherein said first sensitivity relationship predicts workload performance of the processor over a range of operating frequencies; the computer determining a third operating frequency of the processor based on said first sensitivity relationship, wherein said third operating frequency corresponds to a workload performance floor; the computer determining a third performance metric value derived from an execution of said processor operating at said third operating frequency; the computer determining a second sensitivity relationship based on said third performance metric value corresponding to said third operating frequency and said second performance metric value corresponding to said second operating frequency; the computer logically combining said first sensitivity relationship and said second sensitivity relationship to generate a third sensitivity relationship; and the computer outputting a fourth operating frequency of the processor based on said third sensitivity relationship.
