Abstract:
1. A method for managing power consumption in a system including computing devices in both active and one or more inactive states of readiness, the method comprising: receiving, at a processing unit, a request to one of: activate or deactivate one or more computing devices from a respective group of inactive or active computing devices, each said inactive or active computing device initially in a pre-determined state of readiness; activating or deactivating said one or more computing devices, said activating or deactivating resulting in a number of computing devices in one or more states of readiness i; computing an optimal configuration of said computing devices in said one or more said states of readiness i by minimizing an expected power consumption Σ placing said computing devices in said optimized configuration, formulating an objective function to be minimized, said objective function representing said expected power consumption Σ wherein, after one of said activating or deactivating one or more computing devices: computing a resulting activation vector A′ representing said resulting number of computing devices in one or more activation states of readiness i; and computing an activation vector A″ representing a number of computing devices in said optimized one or more activation states of readiness i; wherein said objective function is subject to a constraint that R wherein a program using said processor unit is configured to perform one or more of said receiving, activating, computing, placing, formulating and said computing said activation vectors A′ and A″.
