On Verifying Causal Consistency - École Polytechnique

WebCausal consistency is one of the most adopted consistency criteria for distributed implementations of data structures. It ensures that operations are executed at all sites according to their causal precedence. We address the issue of verifying automatically whether the executions of an implementation of a data structure are causally consistent. … WebFigure 2: The differences between causality criteria can be explained in terms of time zones. The more constraints the past imposes on the present, the stronger the criterion. The zones in plain blue must be respected totally, and the updates of the zones in striped orange must be taken into account. - "Causal consistency: beyond memory" chipmunk\u0027s a2
