OPTIMIZING RUNTIME FRAMEWORK FOR EFFICIENT HARDWARE UTILIZATION AND POWER SAVING

摘要

A system and method are disclosed for polling in a multi-thread computing system. In one embodiment, a method includes actively polling at least one work queue associated with a worker thread; as a result of the at least one work queue being 5 empty during the polling for a first period of time, causing the worker thread to alternately: poll the at least one work queue during at least one polling interval; and enter an autonomous sleep state during at least one sleep interval; and, as a result of the at least one work queue being empty during each polling interval of a back-off period, causing the worker thread to enter a non-autonomous sleep state for a yield 10 period controlled by a wake-up signal.
