Inria Large Scale Initiative on Multicore

Philippe Clauss, Jens Gustedt, Alain Ketterlin, Cédric Bastoul and Vincent Loechner are involved in the Inria Project Lab entitled “Large scale multicore virtualization for performance scaling and portability” and regrouping several French researchers in compilers, parallel computing and program optimization (https://team.inria.fr/multicore). The project started officially in January 2013. In this context and since January 2013, Philippe Clauss is co-advising with Erven Rohou of the Inria team PACAP, Nabil Hallou's PhD thesis focusing on dynamic optimization of binary code. The PhD defense was held December the 18th 2017.

Philippe Clauss, Jens Gustedt and Maxime Mogé are involved in the ADT Inria project ASNAP (Accélération des Simulations Numériques pour l'Assistance Peropératoire), in collaboration with the Inria team MIMESIS. The goal is to find opportunities in the SOFA simulation platform for applying automatic parallelization techniques developed by Camus. We are currently investigating two approaches. The first uses memory behavior memoization to generate a parallel code made of independent threads at runtime. The second uses ordered read-write locks (ORWL) to dynamically schedule a pipeline of parallel tasks.

ANR AJACS

Participant : Arthur Charguéraud [contact] .

The AJACS research project is funded by the programme “Société de l'information et de la communication” of the ANR, from October 2014, until November 2018. http://ajacs.inria.fr/

The goal of the AJACS project is to provide strong security and privacy guarantees on the client side for web application scripts implemented in JavaScript, the most widely used language for the Web. The proposal is to prove correct analyses for JavaScript programs, in particular information flow analyses that guarantee no secret information is leaked to malicious parties. The definition of sub-languages of JavaScript, with certified compilation techniques targeting them, will allow deriving more precise analyses. Another aspect of the proposal is the design and certification of security and privacy enforcement mechanisms for web applications, including the APIs used to program real-world applications. Arthur Charguéraud focuses on the description of a formal semantics for JavaScript, and the development of tools for interactively executing programs step-by-step according to the formal semantics.

Partners: team Celtique (Inria Rennes - Bretagne Atlantique), team Prosecco (Inria Paris), team Indes (Inria Sophia Antipolis - Méditerranée), and Imperial College (London).

ANR Vocal

Participant : Arthur Charguéraud [contact] .

The Vocal research project is funded by the programme “Société de l'information et de la communication” of the ANR, for a period of 48 months, starting on October 1st, 2015. https://vocal.lri.fr/

The goal of the Vocal project is to develop the first formally verified library of efficient general-purpose data structures and algorithms. It targets the OCaml programming language, which allows for fairly efficient code and offers a simple programming model that eases reasoning about programs. The library will be readily available to implementers of safety-critical OCaml programs, such as Coq, Astrée, or Frama-C. It will provide the essential building blocks needed to significantly decrease the cost of developing safe software. The project intends to combine the strengths of three verification tools, namely Coq, Why3, and CFML. It will use Coq to obtain a common mathematical foundation for program specifications, as well as to verify purely functional components. It will use Why3 to verify a broad range of imperative programs with a high degree of proof automation. Finally, it will use CFML for formal reasoning about effectful higher-order functions and data structures making use of pointers and sharing.

Partners: team Gallium (Inria Paris), team DCS (Verimag), TrustInSoft, and OCamlPro.
