The present invention is a method and mechanism of multiple processors synchronization. Calling global memory fence (GMF) service raises asynchronous memory fence being executed on other processors. By guarantee that asynchronous memory fence (AMF) or equivalence on other processors are executed within the window of global memory fence (GMF) service call, the expensive memory ordering semantics can be removed from the critical path of frequently-executed application code. Therefore, the overall performance is improved in modern processor architectures.
