Cependant, leur impl\u00e9mentation classique repose souvent sur des files d\u2019attente, ce qui peut d\u00e9grader les performances en cas de contention \u00e9lev\u00e9e. <strong>QFSync<\/strong> introduit une approche \u00ab <em>queue-free<\/em> \u00bb (sans file), r\u00e9duisant ainsi les latences et am\u00e9liorant le passage \u00e0 l\u2019\u00e9chelle des applications sur les architectures multic\u0153urs modernes.<\/p>\n\n\n\n<p>Cette publication s\u2019inscrit dans une probl\u00e9matique cruciale pour les syst\u00e8mes parall\u00e8les et distribu\u00e9s, o\u00f9 la gestion efficace des ressources et la minimisation des temps d\u2019attente sont des enjeux majeurs.
