Revisiting concurrent separation logic

Pedro Soares, António Ravara, Simão Melo de Sousa
2017 Journal of Logical and Algebraic Methods in Programming  
We present a new soundness proof of Concurrent Separation Logic (CSL) based on a structural operational semantics (SOS).  ...  We build on two previous proofs and develop new auxiliary notions to achieve the goal. One uses a denotational semantics (based on traces).  ...  Concurrent Separation Logic We revisit Concurrent Separation Logic (CSL), as presented by Brookes [4] .  ...

Resources, Concurrency, and Local Reasoning [chapter]

Peter W. O'Hearn
2004 Lecture Notes in Computer Science  
The purpose of this work is to revisit these issues, using the recent formalism of separation logic [11] .  ...  There is thus a mismatch, between the intuitive basis of concurrent programming with resources, where separation remains a vital design idea, and formal techniques for reasoning about such programs, where  ...  The purpose of this work is to revisit these issues, using the recent formalism of separation logic [11] .  ...

A Game Semantics of Concurrent Separation Logic [article]

Paul-André Melliès, Léo Stefanesco
2017 arXiv   pre-print
In this paper, we develop a game-theoretic account of concurrent separation logic.  ...  We establish the soundness of concurrent separation logic by interpreting every derivation tree of the logic as a winning strategy of this specification game.  ...  The syntax and the semantics of the formulas of Concurrent Separation Logic is the same as in Separation Logic.  ...

Bringing Order to the Separation Logic Jungle [chapter]

Qinxiang Cao, Santiago Cuellar, Andrew W. Appel
2017 Lecture Notes in Computer Science  
In this paper, we introduce a unifying semantics and build a framework that allows to reason parametrically over all separation logics.  ...  We prove every separation logic to be sound and complete with respect to this unifying semantics. Further, our framework enables us to generalize the soundness proofs for the frame rule and CSL.  ...  Concurrent separation logic Concurrent separation logic is an extension of separation Hoare logic to reason about concurrent programs.  ...

Rewriting Logic Semantics: From Language Specifications to Formal Analysis Tools [chapter]

José Meseguer, Grigore Roşu
2004 Lecture Notes in Computer Science  
Formal semantic definitions of concurrent languages, when specified in a well-suited semantic framework and supported by generic and efficient formal tools, can be the basis of powerful software analysis  ...  By combining, yet distinguishing, both equations and rules, rewriting logic semantic definitions unify both the semantic equations of equational semantics (in their higher-order denotational version or  ...  modular rewriting logic definitions have been developed in joint work of the first author with Christiano Braga at UFF Brazil.  ...

Towards a Novel Model Versioning Approach Based on the Separation Between Linguistic and Ontological Aspects

Antonio Cicchetti, Federico Ciccozzi
2013 ACM/IEEE International Conference on Model Driven Engineering Languages and Systems  
In particular, we revisit the main versioning tasks in terms of the mentioned separation.  ...  The aim is to maximize the amount of versioning problems that can be automatically addressed while leaving the ones intertwined with domain-specific semantics to be solved separately, possibly by means  ...  Based on the separation mentioned so far, this work revisits the current techniques developed for model version management and outlines a research agenda to cover all the aspects of model versioning.  ...

Back to futures

2022 Journal of functional programming  
Common approaches to concurrent programming begin with languages whose semantics are naturally sequential and add new constructs that provide limited access to concurrency, as exemplified by futures.  ...  This approach has been quite successful, but often does not provide a satisfactory theoretical backing for the concurrency constructs, and it can be difficult to give a good semantics that allows a programmer  ...  However, because both cuts in this term are concurrent cuts, P and Q run concurrently, as we expect from a parallel pair. mapReduce Revisited.  ...

Separation Logic Semantics for Communicating Processes

Tony Hoare, Peter O'Hearn
2008 Electronical Notes in Theoretical Computer Science  
It extends separation logic by an operator for separation in time as well as separation in space.  ...  This paper explores a unification of the ideas of Concurrent Separation Logic with those of Communicating Sequential Processes.  ...  Introduction This paper reports on work bringing together semantic ideas lying behind Concurrent Separation Logic (CSL, [18, 4] ) and Communicating Sequential Processes (CSP, [11] ).  ...

Towards type-theoretic semantics for transactional concurrency

Aleksandar Nanevski, Paul Govereau, Greg Morrisett
2008 Proceedings of the 4th international workshop on Types in language design and implementation - TLDI '09  
As a programming language, we define its operational semantics and show adequacy with respect to specifications.  ...  HTT follows Separation Logic in providing tight specifications of space requirements. As a logic, we argue that HTT is sound and compositional.  ...  To our knowledge, none of the mentioned languages and logics has been extended to a concurrent setting. Separation Logic and concurrency.  ...

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  
We present the first semantics of separation logic that is sensitive to atomicity, and show how to control this sensitivity through ownership.  ...  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.  ...
