Abstract
In at least one embodiment, a method includes locally scheduling a memory request requested by a thread of a plurality of threads executing on at least one processor. The memory request is locally scheduled according to a quality-of-service priority of the thread. The quality-of-service priority of the thread is based on a quality of service indicator for the thread and system-wide memory bandwidth usage information for the thread. In at least one embodiment, the method includes determining the system-wide memory bandwidth usage information for the thread based on local memory bandwidth usage information associated with the thread periodically collected from a plurality of memory controllers during a timeframe. In at least one embodiment, the method includes at each mini-timeframe of the timeframe accumulating the system-wide memory bandwidth usage information for the thread and updating the quality-of-service priority based on the accumulated system-wide memory bandwidth usage information for the thread.
