Abstract
Managing lock and unlock operations for a first thread executing on a first processor core includes, for each instruction included in the first thread and identified as being associated with: (1) a lock operation corresponding to a particular lock, in response to determining that the particular lock has already been acquired, continuing to perform the lock operation for multiple attempts during which the first processor core is not able to execute threads other than the first thread, or (2) an unlock operation corresponding to a particular lock, releasing the particular lock from the first thread. Prioritization of selected messages sent over interconnection circuitry configured to connect each processor core to a memory system of the processor is preserved. The selected messages associated with instructions identified as being associated with an unlock operation are prioritized over messages associated with instructions identified as being associated with a lock operation.
