Automata and fixpoints for asynchronous hyperproperties

JO Gutsfeld, M Müller-Olm, C Ohrem - Proceedings of the ACM on …, 2021 - dl.acm.org
Hyperproperties have received increasing attention in the last decade due to their
importance eg for security analyses. Past approaches have focussed on synchronous …

The power of well-structured systems

S Schmitz, P Schnoebelen - International Conference on Concurrency …, 2013 - Springer
Well-structured systems, aka WSTS, are computational models where the set of possible
configurations is equipped with a well-quasi-ordering which is compatible with the transition …

Kee** a crowd safe: On the complexity of parameterized verification (invited talk)

J Esparza - 31st International Symposium on Theoretical Aspects …, 2014 - drops.dagstuhl.de
We survey some results on the automatic verification of parameterized programs without
identities. These are systems composed of arbitrarily many components, all of them running …

Parameterized verification under release acquire is PSPACE-complete

S Krishna, A Godbole, R Meyer… - Proceedings of the 2022 …, 2022 - dl.acm.org
We study the safety verification problem for parameterized systems under the release-
acquire (RA) semantics. In the non-parameterized setting, access to atomic compare-and …

Parameterized verification under TSO is PSPACE-complete

PA Abdulla, MF Atig, R Rezvan - Proceedings of the ACM on …, 2019 - dl.acm.org
We consider parameterized verification of concurrent programs under the Total Store Order
(TSO) semantics. A program consists of a set of processes that share a set of variables on …

SMT and POR beat counter abstraction: Parameterized model checking of threshold-based distributed algorithms

I Konnov, H Veith, J Widder - International Conference on Computer Aided …, 2015 - Springer
Automatic verification of threshold-based fault-tolerant distributed algorithms (FTDA) is
challenging: they have multiple parameters that are restricted by arithmetic conditions, the …

Reachability in networks of register protocols under stochastic schedulers

P Bouyer, N Markey, M Randour, A Sangnier… - arxiv preprint arxiv …, 2016 - arxiv.org
We study the almost-sure reachability problem in a distributed system obtained as the
asynchronous composition of N copies (called processes) of the same automaton (called …

Parameterized verification under TSO with data types

PA Abdulla, MF Atig, F Furbach, AA Godbole… - … Conference on Tools …, 2023 - Springer
We consider parameterized verification of systems executing according to the total store
ordering (TSO) semantics. The processes manipulate abstract data types over potentially …

A compositional deadlock detector for android java

J Brotherston, P Brunet, N Gorogiannis… - 2021 36th IEEE/ACM …, 2021 - ieeexplore.ieee.org
We develop a static deadlock analysis for commercial Android Java applications, of sizes in
the tens of millions of LoC, under active development at Facebook. The analysis runs …

Safety of parametrized asynchronous shared-memory systems is almost always decidable

S La Torre, A Muscholl… - … on Concurrency Theory …, 2015 - drops.dagstuhl.de
Verification of concurrent systems is a difficult problem in general, and this is the case even
more in a parametrized setting where unboundedly many concurrent components are …
