Abstract
In a shared memory process different threads may attempt to access a shared data variable in a shared memory. Locks are provided to synchronize access to shared data variables. Each lock is allocated to have a location in the shared memory relative to the instance of shared data that the lock protects. A lock may be allocated to be adjacent to the data that it protects. Lock resolution is facilitated because the memory location of a lock can be determined from an offset with respect to the data variable that is being protected by the lock.
