Abstract

The behaviour of Distributed Shared Memory Systems is dictated by the memory consistency model. In order to provide a better understanding on the semantics of the memory models, many researchers have proposed formalisms to define them. Even with formal definitions, it is still difficult to say what kind of execution histories can be produced on a particular memory model. In this paper, we propose Visual-MCM, a visualisation tool that shows what operations orderings could lead to user-defined execution histories on different memory models. We also present a prototype of Visual-MCM that analyses execution histories for two different memory consistency models.
