Abstract
A method and apparatus for power management is disclosed. The invention reduces power consumption in multiprocessing systems by dynamically adjusting processor power based on system workload. Particularly, the method and apparatus determines the number of required processors based on the number or active threads and sets a processor affinity to run the active threads on the determined number of required processors, thereby allowing the free processors to enter a low-power state.
