Outline of Final Research Achievements

We came up with how to specify a distributed snapshot algorithm (DSA) as a meta-program (MP) in Maude, a computer language based on rewriting logic, and how to directly model check the distributed snapshot reachability (DSR) property, and confirmed the usefulness by conducting several case studies. An existing approach makes it necessary to specify a DSA for each distributed system (DS), while the proposed approach does not. It suffices to specify DSA once as an MP and specify each DS only as the DS is taken into account. Since the DSR property can be directly model checked, the proposed approach performs model checking faster than the existing approach and generates a counterexample when the property is not satisfied. The proposed approach can also be applied to distributed algorithms whose computational targets are DSs.
