A tactic language for refinement of state-rich concurrent specifications

Marcel Oliveira, Frank Zeyda, Ana Cavalcanti
2011 Science of Computer Programming  
Circus is a refinement language in which specifications define both data and behavioural aspects of concurrent systems using a combination of Z and CSP.  ...  Here, we present ArcAngelC , a language for defining such tactics; we present the language, its semantics, and its application in the formalisation of an existing strategy for verification of Ada implementations  ...  The function applyTacsGC takes two lists: the first is a list of tactics and the second is a list of refinement cells.  ...

An Event-Based SOS for a Language with Refinement [chapter]

It is usually introduced in the form of an operator in a process algebraic language, for which a denotational semantics in a suitable model is then given.  ...  In this paper we complement this approach b y de ning a corresponding operational semantics for re nement, in the form of derivation rules for a transition relation.  ...  Introduction Process algebras form a well-known speci cation paradigm for concurrent systems.  ...

A separation logic for refining concurrent objects

Aaron Joseph Turon, Mitchell Wand
2011 Proceedings of the 38th annual ACM SIGPLAN-SIGACT symposium on Principles of programming languages - POPL '11  
Fine-grained concurrent data structures are crucial for gaining performance from multiprocessing, but their design is a subtle art.  ...  In this paper we show how the ownership discipline of separation logic can be used to enable atomicity refinement, and we develop a new rely-guarantee method that is localized to the definition of a data  ...  Acknowledgements Thanks to Dan Brown, Claudio Russo and Sam Tobin-Hochstadt for feedback and discussions. The first author was supported by a grant from Microsoft Research.  ...

A Formal Method for Specifying The Interface of Components in Real-time Concurrent Systems

Do Van Chieu
2015 Research and Development on Information and Communication Technology  
In this paper, we propose a method for specifying the interface of components in real-time concurrent systems.  ...  In addition, we propose a class of automata that can recognize a class of timed trace languages called timed concurrent interface automata.  ...  Definitions As introduced in Section 1, the protocol of a realtime concurrent component interface is timed trace language. For the finite representation of the languages, we use ADA.  ...

Hongjin Liang, Xinyu Feng, Ming Fu
2012 Proceedings of the 39th annual ACM SIGPLAN-SIGACT symposium on Principles of programming languages - POPL '12  
In this paper, we propose a Rely-Guarantee-based Simulation (RGSim) to verify concurrent program transformations.  ...  We also propose a general garbage collector verification framework based on RGSim, and verify the Boehm et al. concurrent mark-sweep GC.  ...  Here we propose a more direct approach. We view a concurrent garbage collecting system as a transformation T from a high-level garbage-collected language to a low-level language.  ...
