This paper proposes a new consistency model for software shared virtual memory, called Scope Consistency (ScC), which offers most of the potential performance advantages of the EC model but requires a programming interface as simple as that of RC or LRC. It does this by exploiting the implicit dynamic binding between data and synchronization events variables. In our simulation studies, we compared ScC with Automatic Update Release Consistency (AURC), a modified LRC model that takes advantage of new network interfaces. For two of the four real applications we used, ScC reduced the running time by about 11%.
