Towards Parameterized Contract Validator in ANaConDA Framework

This work deals with problematics of contracts for parallelism. It is a technique allowing to specify requirements for atomicity in parallel programs and to create automatic tools for detection of atomicity violation. ANaConDA framework provides dynamic analyser called Contract-validator which can detect contract violations in parallel programs. However, due to analysis without context, it can produce a lot of warnings about contract violation that are not considered as errors. The aim of this work was to design and implement a method supporting contracts extended with parameters and their constraints which will lead to more accurate results of the analysis. Experiments using newly created analyser on a set of benchmarks with known atomicity violations showed that analysis with parameters can reduce the results by dozens of reports that unnecessarily burdened developers and made it harder to reveal real errors
