Abstract
A multiprocessor system dynamically updates CPU affinities for processes executing on processors of the multiprocessor system based on an external signal. The external signal is generated by a monitor device. The external signal identifies the processors and the processes that require updating. In response to the external signal, the multiprocessor system redistributes the processes identified in the external signal and powers on or off one or more processors based on a processor threshold associated with the multiprocessor system.
