Multi-thread processing system for detecting and handling live-lock conditions by arbitrating livelock priority of logical processors based on a predertermined amount of time

摘要

Method, apparatus and system embodiments to assign priority to a thread when the thread is otherwise unable to proceed with instruction retirement. For at least one embodiment, the thread is one of a plurality of active threads in a multiprocessor system that includes memory livelock breaker logic and/or starvation avoidance logic. Other embodiments are also described and claimed.
