ABSTRACT:
A technique releases locks associated with particular memory locations. The technique uses a “background” approach to determining when the locks should be released in that memory operations associated with the memory locations are monitored while instructions continue to execute on a processor. The memory operations are monitored by generating a condition for each memory operation and clearing the condition when the operation completes. When all the conditions are cleared, the associated locks are released.
