Abstract
A system with improved power performance for tasks executed in parallel. A plurality of processing cores each to execute tasks. An inter-core messaging unit to conveys messages between the cores. A power management agent transitions a first core into a lower power state responsive to the first core waiting for a second core to complete a second task. In some embodiments long messages are subdivided to allow a receiving core to resume useful work sooner.
