A dynamic power management strategy selection method and module

Abstract

The invention relates to a method and a module for dynamic power management strategy selection. The method is achieved based on a dynamic power management framework, a strategy selection layer is arranged in the dynamic power management framework and used for strategy selection, the method concretely includes: at the moment t using a strategy i to carry out dynamic power management on system components; sensing the states of the system components, receiving feedback information of the system component environment, evaluating a loss value of a current selected strategy, and evaluating loss values of other selectable strategies through the simulation of the dynamic power management of the system components with the other selectable strategies; according to the loss values, dynamically updating selected probability of the selectable strategies, and selecting the strategy corresponding to the maximum selected probability as an optimal strategy; and carrying out the dynamic power management on the system components with the optimal strategy, when the optimal strategy acts on the system components, the system components transferring to next moment t+1, and executing the strategy selection in a looping mode. According to the method and the module for the dynamic power management strategy selection, a dynamic power management strategy can be selected dynamically in the versatile real environment to achieve a better energy-saving effect.

Description

technical field [0001] The invention belongs to the technical field of computer dynamic power management, and in particular relates to a dynamic power management strategy selection method and a module. Background technique [0002] Energy consumption is a key issue in today's computer system design, and the contradiction between high performance and low power consumption is becoming increasingly prominent. [0003] Dynamic Power Management (Dynamic Power Management, DPM) is a system-level low-power consumption technology. According to the requested service and performance requirements, through the dynamic configuration of the system components, the state of the system components is dynamically converted, and as few as possible are started. Components or put them in an appropriate energy consumption state, so as to achieve the effective use of energy consumption. [0004] Strategy optimization is the key point of dynamic power management. Traditional dynamic power management...

In the technical solution disclosed in this patent, the strategy optimization is only realized by the Markov model, and the strategy is calculated through the Markov model, and the instructions of the system equipment are controlled according to the strategy, that is to say, only one strategy can be selected for one system equipment Management is performed to achieve state transition, which makes the power management strategy of system components solidified, and cannot dynamically adjust its own strategy according to the actual operating environment to save more energy

For the Chinese patent CN200810030260.8, the name is a disk dynamic power management method based on an embedded system, which has the same problem as the above-mentioned patent. For the power management of the disk, only the update model is used for strategy optimization, and there is no Provide a platform for disks that can choose different strategies for optimization to achieve dynamic policy management
