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 stored in a particular memory location, in response to determining that the particular lock has already been acquired, continuing to perform the lock operation for multiple attempts using associated operation messages for accessing the particular memory location, or (2) an unlock operation corresponding to a particular lock stored in a particular memory location, releasing the particular lock from the first thread using an associated operation message for accessing the particular memory location. Selected operation messages associated with an unlock operation are prioritized over operation messages associated with a lock operation.
