Cette thèse a pour but de définir et de développer des solutions informatiques de manière à permettre la mise en place de simulations physiques sur des domaines de simulation très grands tels qu'un site industriel comme le terminal méthanier de Dunkerque. Le modèle d'écoulement mis en place est basé sur la méthode de Boltzmann sur réseau et permet de gérer de nombreux cas de simulation. Différentes architectures de calculs sont étudiées dans ce travail de thèse. L'utilisation du processeur central ainsi que de processeurs graphiques pour la parallélisation des calculs est abordée. Des solutions sont mises en place de manière à obtenir une parallélisation efficace du modèle de calcul sur plusieurs GPUS pouvant calculer en parallèle. Une appr...
