ABSTRACT:
A method and system to selectively move one or more of a plurality threads which are executing in parallel by a plurality of processing cores. In one embodiment, a thread may be moved from executing in one of the plurality of processing cores to executing in another of the plurality of processing cores, the moving based on a performance characteristic associated with the plurality of threads. In another embodiment of the invention, a power state of the plurality of processing cores may be changed to improve a power efficiency associated with the executing of the multiple threads.
