We report on the process for formal concurrency modelling at Arm. An initial formal
consistency model of the Arm achitecture, written in the cat language, was published and …

GenMC is an LLVM-based state-of-the-art stateless model checker for concurrent C/C++
programs. Its modular infrastructure allows it to support complex memory models, such as …

Program logics and semantics tell a pleasant story about sequential composition: when
executing (S1; S2), we first execute S1 then S2. To improve performance, however …

Liveness properties, such as termination, of even the simplest shared-memory concurrent
programs under sequential consistency typically require some fairness assumptions about …

In this article, we propose an approach to program verification using an abstract
characterisation of weak memory models. Our approach is based on a hierarchical axiom …

Deductive verification techniques for C11 programs have advanced significantly in recent
years with the development of operational semantics and associated logics for increasingly …

We investigate the problem of developing an" in-order" shared-memory concurrency model
for languages like C and C++, which executes instructions following their program order …

We present a compositional denotational semantics for a functional language with first-class
parallel composition and shared-memory operations whose operational semantics follows …

Local data-race-freedom guarantees, ensuring strong semantics for locations accessed by
non-racy instructions, provide a fruitful methodology for modular reasoning in relaxed …

We formally show that sequential reasoning is adequate and sufficient for establishing
soundness of various compiler optimizations under weakly consistent shared-memory …
