Editing Release consistency (section)

=== Hardware structure and program-level effort ===
Sequential consistency can be achieved simply by hardware implementation, while release consistency is also based on an observation that most of the parallel programs are properly synchronized. In programming level, synchronization is applied to clearly schedule a certain memory access in one thread to occur after another. When a synchronized variable is accessed, hardware would make sure that all writes local to a processor have been propagated to all other processors and all writes from other processors are seen and gathered. In release consistency model, the action of entering and leaving a [[critical section]] are classified as ''acquire'' and ''release'' and for either case, explicit code should be put in the program showing when to do these operations''.''
