Linearizability is an important correctness criterion for implementations of concurrent objects. Automatic checking of linearizability is challenging because it requires checking that: 1) All executions of concurrent operations are serializable, and 2) the serialized executions are correct with respect to the sequential semantics. In this work, we describe a method to automatically check linearizability...
Concurrent objects are notoriously difficult to design correctly, and high performance algorithms that make little or no use of locks even more so. In this paper, we present a formal verification of a lazy concurrent list-based set using model checking techniques. The algorithm supports insertion, removal, and membership testing of a list entry under optimistic locking scheme. The algorithm has nonfixed...
UML has become the dominant modeling language in software engineering arena. In order to reduce cost induced by design issues, it is crucial to detect model-level errors in the initial phase of software development. In this paper, we focus on the formal verification of dynamic behavior of UML diagrams. We present an approach to automatically verifying models composed of UML state machines. Our approach...
