Thread-Modular Static Analysis by Abstract Interpretation: designing relational abstractions of interferences

International audienceIn this document, we use the Abstract Interpretation framework to analyze concurrent programs using Thread-Modular Analysis. We designed a relational abstraction of interferences in order to infer more properties and go beyond the state of the art. We implemented a basic analyzer, studying the numerical properties of a simple language. We present the results obtained, as well as a study of the scalability of this approach
