une augmentation consid茅rable en tremes de besoins informatiques dans les ann茅es 脿 venir, d茅passant ce qui devrait 锚tre r茅alisable avec un budget d'investissement constant. Les besoins en capacit茅 de stockage et de calcul seront sup茅rieurs de plusieurs ordres de grandeur 脿 ce que, 脿 budget constant, les projections en termes de progr猫s technologiques permettent d鈥檈sp茅rer. Lorsque le LHC 脿 haute luminosit茅, HL-LHC, sera op茅rationnel en 2029, les besoins en traitement et stockage de donn茅es devraient 锚tre dix fois plus importants qu'aujourd'hui.</p> <p>Pour rem茅dier 脿 ce probl猫me, la Fondation HSF (HEP Software Foundation) a publi茅 cette ann茅e <a href="https://arxiv.org/abs/1712.06982">un livre blanc, une forme de feuille de route pour la communaut茅</a>, qui explore les d茅fis informatiques 脿 venir et d茅crit les m茅canismes possibles pour les surmonter.</p> <p>D鈥檃utres communaut茅s scientifiques sont aussi confront茅es 脿 de tels d茅fis. 脌 titre d鈥檈xemple, le CERN et la Grille WLCG collaborent avec la communaut茅 de la radioastronomie g茅rant le projet de radiot茅lescope Square Kilometer Array (SKA). Au mois de juin, le CERN et SKA ont sign茅 un accord de collaboration portant sur la capacit茅 de calcul et la gestion de donn茅es.</p> <p>CERN openlab a 茅galement publi茅 en 2017 <a
