On verifying causal consistency

Webcausal consistency, delaying the execution of the operation if necessary. Charron-Bost in1991 [9] proved that, to provide the ability to check for concurrency in causal consistency (i.e., char-acterising causality or verifying causal independence), the minimum necessary metadata attached to any operation is 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"

We address the verification problem of eventual consistency of optimistic … WebCausal consistency for instance is one such model that is widely used in practice. In this paper, we investigate application-specific relationships between several varia-tions of causal consistency and we address the issue of verifying automatically if a given transactional program is robust against causal consistency, i.e., all its behaviors when diaper rash that looks like a burn

WebIn principle, algorithmically checking the consistency of executions according to various weak-consistency criteria is hard: in addition to the enumeration of linearizations of an execution’s operations, such criteria generally demand the enumeration of possible visibility relations among the linearized operations; a priori, both enumerations are exponential.
