    摘要： A system for identifying a subset of sensors to sample to reduce the frequency of sensor access. The system determines rise times and records values for the sensors in the system. A time criticality of the sensors is determined based on the rise times. The system processes the sensors by first creating sensor subsets based on one or more constraints on the sensors. The system monitors the values of the sensors in a sensor subset and flags a sensor when it makes a determination that, prior to a next scheduled sampling of the sensor subset, the value of a sensor in the monitored sensor subset will exceed a threshold constraint. The system moves those flagged sensors to a second sensor subset which complies with the sensor's constraints.

    摘要： A method, computer program product, and apparatus for managing power in a data processing system are presented. A core is activated in the data processing system and configured to operate at a frequency in response to receiving a request to increase a processing capacity of a set of resources in the data processing system. A determination whether a use of power resulting from activating the core configured to operate at the frequency meets a policy for the use of the power in the data processing system is made. A set of parameters associated with devices in the set of resources are adjusted to meet the policy for the use of power in the data processing system in response to a determination that the use of power does not meet the policy. A determination whether a number of operations performed per unit of time by a set of cores associated with the set of resources increased after activating the core is made. An indication that the request to increase the processing capacity of the set of resources is unavailable is made in response to a determination that the number of operations performed per unit of time by the set of cores associated with the set of resources has not increased.
