Unbounded Lazy-CSeq: A Lazy Sequentialization Tool for C Programs with Unbounded Context Switches - (Competition Contribution)
نویسندگان
چکیده
We describe a new CSeq module for the verification of multi-threaded C programs with dynamic thread creation. This module implements a variation of the lazy sequentialization algorithm implemented in Lazy-CSeq. The main novelty is that we now support an unbounded number of context switches and allow unbounded loops, while the number of allowed threads still remains bounded. This is achieved by a modified sequentialization transformation and the use of the CPAchecker as sequential verification backend.

Lazy-CSeq: A Lazy Sequentialization Tool for C - (Competition Contribution)
We describe a version of the lazy sequentialization schema by La Torre, Madhusudan, and Parlato that is optimized for bounded programs, and avoids the re-computation of the local state of each process at each context switch. Lazy-CSeq implements this sequentialization schema for sequentially consistent C programs using POSIX threads. Experiments show that it is very competitive.
متن کاملLazy Sequentialization for the Safety Verification of Unbounded Concurrent Programs
Lazy sequentialization has emerged as one of the most promising approaches for concurrent program analysis but the only efficient implementation given so far works just for bounded programs. This restricts the approach to bugfinding purposes. In this paper, we describe and evaluate a new lazy sequentialization translation that does not unwind loops and thus allows to analyze unbounded computati...
متن کاملLazy-CSeq-SP: Boosting Sequentialization-Based Verification of Multi-threaded C Programs via Symbolic Pruning of Redundant Schedules
Sequentialization has been shown to be an effective symbolic verification technique for concurrent C programs using POSIX threads. Lazy-CSeq, a tool that applies a lazy sequentialization scheme, has won the Concurrency division of the last two editions of the Competition on Software Verification. The tool encodes all thread schedules up to a given bound into a single non-deterministic sequentia...
متن کاملCSeq: A Sequentialization Tool for C - (Competition Contribution)
Sequentialization translates concurrent programs into equivalent nondeterministic sequential programs so that the different concurrent schedules no longer need to be handled explicitly. It can thus be used as a concurrency preprocessor for many sequential program verification techniques. CSeq implements sequentialization for C and uses ESBMC as sequential verification backend [5].
متن کاملMU-CSeq: Sequentialization of C Programs by Shared Memory Unwindings - (Competition Contribution)
We implement a new sequentialization algorithm for multi-threaded C programs with dynamic thread creation as a new CSeq module. The novel basic idea of this algorithm is to fix (by a nondeterministic guess) the sequence of write operations in the shared memory and then simulate the behavior of the program according to any scheduling that respects this choice. Simulation is done threadby-thread ...
