Abstract

We present a sound and fullyautomated method for the verification of safetyprop erties of parameterized systems with unbounded local data variables, a new class of infinite-state systems parametric in several dimensions. The method builds upon a specification and an assertional language based on the combination of multiset rewriting and constraints. We introduce new classes of parameterized systems for which verification of safetyprop erties is decidable, and we introduce abstractions, defined at the level of constraints, to handle examples outside these classes. As case-study, we applythe method to verifyfullyautomatically mutual exclusion properties for formulations of the ticket mutual exclusion algorithm parametric in the number of clients, servers, and in which both clients and servers have unbounded local data.
