Abstract
A system, method, and computer program product are disclosed for reducing overhead associated with software lock monitoring in a multiple-processor data processing system having a memory that is shared among the multiple processors. Multiple memory locations in the shared-memory are associated with one of multiple locks. Overhead is reduced by generating a trace hook only in response to activity associated with lock misses.
