Séminaire Performance et Généricité du LRDE le Mercredi 26 novembre 2008

12 Nov '08

Chers collègues, la prochaine session du séminaire Performance et Généricité du LRDE (Laboratoire de Recherche et Développement de l'EPITA) aura lieu le Mercredi 26 novembre 2008 (14h-17h). Au programme: * 14h: Mesure de Performance et Généricité à EDF R&D -- Laurent Plagne ; EDF R&D Clamart. L'outil BTL++ (Benchmark Template Library in C++) développé à EDF R&D se fonde sur la programmation générique et permet de mesurer les performances de noyaux de calcul intensif. Il s'agit d'une bibliothèque générique dont la conception vise à faciliter l'extensibilité par l'utilisateur. Récemment, le lien entre les mesures de performance et la génération automatique de bibliothèques optimales à été étudié pour le domaine de l'algèbre linéaire dense. Quelques mesures de performance de noyaux de calcul à base d'"Expression Template" permettront d'illustrer l'usage de l'outil BTL++. Laurent Plagne received his PhD in physics from the University of Grenoble, France. He is a research engineer at Electricité de France, one of largest electricity utilities in Europe. His research interests include parallel PDE solvers, High Performance Computing through Object Oriented and Generic programming. The management of the ever growing complexity of simulation tools in the industrial context is a recurring topic in his work. He co-authored a versatile library for performance assessment (BTL++) and is the main developer of a block-recursive linear algebra library in C++ (LEGOLAS++). * 15h15: Bibliothèque générique multi-cible d'algèbre linéaire -- Wilfried Kirschenmann, EDF R&D La multiplication des architectures HPC (CPU multi-coeurs, GPU, Cell,..) implique autant de spécialisations des codes de calcul intensif. Dans un contexte industriel, les codes de calcul multi-cibles posent alors des problèmes de maintenance et d'évolutivité importants. La génération automatique des spécialisations est une réponse à ces problématiques. Pour le domaine de l'algèbre linéaire, nous étudions les possibilités offertes par la programmation générique. La mise au point d'une bibliothèque générique multi-cible et performante constitue le sujet de départ d'une thèse dédiée aux méthodes de développement HPC qui minimisent l'adhérence aux machines cibles. Wilfried Kirschenmann est diplômé de l'école supérieure d'électricité. Il a travaillé sur la parallélisation d'un solveur de neutronique sur processeur graphique lors de son stage de fin d'étude à EDF R&D. Il va débuter une thèse sur les méthodes de développement HPC qui minimisent l'adhérence aux machines cibles. L'entrée du séminaire est libre.

[CFP] 2nd European Lisp Symposium, Milan, May 27-29 2009

************************************************************************ * * * 2nd European Lisp Symposium (ELS 2009) * * * * Milan, Italy, May 27-29, 2009 * * Università degli Studi di Milano-Bicocca * * * ************************************************************************ Important Dates: **************** * Submission deadline January 25, 2009 * Author notification February 27, 2009 * Final paper due March 23, 2009 * Symposium May 27-29, 2009 Accepted research papers will be invited for a special issue of the Journal of Universal Computer Science (J.UCS). See the symposium website for more details. Scope: ****** The purpose of the European Lisp Symposium is to provide a forum for the discussion of all aspects of the design, implementation and application of any of the Lisp dialects. We encourage everyone interested in Lisp to participate. The European Lisp Symposium 2009 invites high quality papers about novel research results, insights and lessons learned from practical applications, and educational perspectives, all involving Lisp dialects, including Common Lisp, Scheme, Emacs Lisp, AutoLisp, ISLISP, Dylan, Clojure, and so on. Topics include, but are not limited to: * Language design and implementation techniques * Language integration, interoperation and deployment * Language critique and future directions * Reflection and meta-level architectures * Educational approaches * Software adaptation and evolution * Configuration management * Artificial intelligence * Large and ultra-large-scale systems * Development methodologies * Development support and environments * Persistent systems * Scientific computing * Parallel and distributed computing * Data mining * Semantic web * Dynamic optimization * Innovative applications * Hardware and virtual machine support * Domain-oriented programming * Lisp pearls * Experience reports and case studies We also encourage submissions about past approaches that have been largely forgotten about, as long as they are presented in a new setting. We invite submissions in two categories: original contributions and work-in-progress papers. * Original contributions have neither been published previously nor are under review by other refereed events or publications. Research papers should describe work that advances the current state of the art, or presents old results from a new perspective. Experience papers should be of broad interest and should describe insights gained from substantive practical applications. The program committee will evaluate each contributed paper based on its relevance, significance, clarity, and originality. * Work in progress describes ongoing work that is not ready for publication yet, but would benefit strongly from feedback by other researchers, practitioners and educators. Such contributions will not be published in the symposium proceedings, but will be made available at the symposium website. The work-in-progress track will be organized as a series of writers' workshops where authors work together to improve their papers. Some authors who submit papers for the main track will be suggested to contribute their work in this track instead, if the program committee decides that their submission is not yet ready for a publication. The writers' workshops will take place at the symposium in Milan on May 27, 2008.
