Abstract:
A method and apparatus of operating a central processing unit (CPU) including a plurality of processors, is provided and includes collecting real-time statistics relating to the processors during dispatching activities, identifying give-help processors from the real-time statistics when the real-time statistics indicate that one or more of the nodes is overworked, and implementing help to be provided by the give-help processor to relieve the overworked node of a portion of the work to be distributed thereto.
