Lucy-n is a dataflow programming language similar to Lustre extended with a buffer operator. This language is based on the n-synchronous model which was initially introduced for programming multimedia streaming applications. In this article, we show that Lucy-n is also applicable to model Latency Insensitive Designs (LID). In order to model relay stations, we have to introduce a delay operator. Thanks to this new operator, a LID can be described by a Lucy-n program. Then, the Lucy-n compiler automatically provides static schedules for computation nodes and buffer sizes needed in the shell wrappers.

Why3 is the next generation of the Why software verification platform. Why3 clearly separates the purely logical specification part from generation of verification conditions for programs. This article focuses on the former part. Why3 comes with a new enhanced language of logical specification. It features a rich library of proof task transformations that can be chained to produce a suitable input for a large set of theorem provers, including SMT solvers, TPTP provers, as well as interactive proof assistants.

For critical software development, containers such as lists, vectors, sets or maps are an attractive alternative to ad-hoc data structures based on pointers. As standards like DO-178C put formal verification and testing on an equal footing, it is important to give users the ability to apply both to the verification of code using containers. In this paper, we present a definition of containers whose aim is to facilitate their use in certified software, using modern proof technology and novel specification languages. Correct usage of containers and user-provided correctness properties can be checked either by execution during testing or by formal proof with an automatic prover. We present a formal semantics for containers and an axiomatization of this semantics targeted at automatic provers. We have proved in Coq that the formal semantics is consistent and that the axiomatization thereof is correct.

Functory: A distributed computing library for Objective Caml.
In Trends in Functional Programming, volume 7193 of
Lecture Notes in Computer Science, pages 65--81, Madrid, Spain, May 2011.
[ bib |
We present Functory, a distributed computing library for Objective Caml. The main features of this library include (1) a polymorphic API, (2) several implementations to adapt to different deployment scenarios such as sequential, multi-core or network, and (3) a reliable fault-tolerance mechanism. This paper describes the motivation behind this work, as well as the design and implementation of the library. It also demonstrates the potential of the library using realistic experiments.

Divide and recycle: types and compilation for a hybrid synchronous
In ACM SIGPLAN/SIGBED Conference on Languages, Compilers, Tools

Hybrid modelers such as Simulink have become corner stones of embedded systems development. They allow both discrete controllers and their continuous environments to be expressed in a single language. Despite the availability of such tools, there remain a number of issues related to the lack of reproducibility of simulations and to the separation of the continuous part, which has to be exercised by a numerical solver, from the discrete part, which must be guaranteed not to evolve during a step.

Typage des horloges périodiques en Lucy-n.
In Sylvain Conchon, editor, Vingt-deuxièmes Journées
Francophones des Langages Applicatifs, La Bresse, France, January 2011.
[ bib |
Lucy-n est un langage permettant de programmer des réseaux de processus communiquant à travers des buffers de taille bornée. La taille des buffers et les rythmes d'exécution relatifs des processus sont calculés par une phase de typage appelée calcul d'horloge. Ce typage nécessite la résolution d'un ensemble de contraintes de sous-typage. L'an dernier, nous avons proposé un algorithme de résolution de ces contraintes utilisant des méthodes issues de l'interprétation abstraite. Cette année nous présentons un algorithme tirant profit de toute l'information contenue dans les types.
