ACM Transactions on Programming Languages and Systems

Software Transactional Memory (STM) is an attractive basis for the development of language features for concurrent programming. However, the semantics of these features can be delicate and problematic. In this article we explore the trade-offs semantic ...

Locksmith is a static analysis tool for automatically detecting data races in C programs. In this article, we describe each of Locksmith's component analyses precisely, and present systematic measurements that isolate interesting trade-offs between ...

Concurrent objects are inherently complex to verify. In the late 80s and early 90s, Herlihy and Wing proposed linearizability as a correctness condition for concurrent objects, which, once proven, allows us to reason about concurrent objects using pre- ...

Developing a theory of bisimulation in higher-order languages can be hard. Particularly challenging can be: (1) the proof of congruence, as well as enhancements of the bisimulation proof method with “up-to context” techniques, and (2) obtaining ...
