A method of optimizing memory synchronization through software in a multi-threaded computer system using a read-initiated memory synchronization process is described. One or more embodiments of the invention may operate in a computer system capable of executing at least one computational activity needing exclusive access shared memory. In the method of one or more embodiments, a multi-field lock may be associated with shared memory to reserved it for exclusive use by a first processor, and where the multi-field lock is already reserved by a second processor, synchronizing the shared memory by the second processor, updating the multi-field lock reservation information; and performing instruction synchronization for the first processor.
