Abstract
A method, apparatus, and program product are provided for managing power consumption in a computer system based on the degree with which performance of tasks can be degraded in order to save power. A criticality value controls the degree with which performance of a task may be degraded is associated with tasks within a computer system. Power consumption of the computer system is then managed based on the criticality values associated with tasks executing within the computer system. A reduction in computer system power consumption can be realized by degrading the performance of non-critical tasks, which is accomplished by reducing the power consumed by at least a portion of the computer system. Power can also be reduced by scheduling non-critical tasks to portions of the computer system and reducing power consumption of other portions of the computer system.
