Pour mieux comprendre la structure mol\u00e9culaire du virus COVID19 , sous l\u2019impulsion de Jean-Philip Piquemal, professeur Sorbonne Universit\u00e9, directeur du laboratoire de chimie th\u00e9orique \u00e0 la Facult\u00e9 des Sciences et Ing\u00e9nierie de Sorbonne Universit\u00e9 et professeur adjoint \u00e0 l’universit\u00e9 de  Texas \u00e0 Austin (Etats-Unis), des scientifiques de nombreuses institutions collaborent pour simuler et cibler les prot\u00e9ines fonctionnelles du virus #COVID19. Ces mod\u00e8les informatiques aideront les scientifiques \u00e0 concevoir de nouveaux m\u00e9dicaments capables de neutraliser le coronavirus en l’emp\u00eachant de p\u00e9n\u00e9trer dans les cellules humaines ou en bloquant ses m\u00e9canismes internes.<\/p>\n

Les chercheurs s\u2019appuient sur un acc\u00e8s prioritaire (urgent computing) \u00e0 Jean Zay, le supercalculateur converg\u00e9 HPC et IA (16 PFlop\/s) le plus performant en Europe et sur l’approche multi-GPU massivement parall\u00e8le la plus rapide existante pour les simulations de dynamique mol\u00e9culaire de nouvelle g\u00e9n\u00e9ration #Tinker-HP<\/a>.<\/p>\n

Optimis\u00e9e par HPE (Hewlett Packard Enterprise), IDRIS et les d\u00e9veloppeurs de l’application, la solution logicielle Tinker-HP, offre d\u2019ores et d\u00e9j\u00e0 un environnement de calcul haute performance permettant d’acc\u00e9der \u00e0 la mod\u00e9lisation de syst\u00e8mes complexes comptant jusqu’\u00e0 des millions d’atomes. Il s’agit actuellement de l’approche la plus rapide et op\u00e9rationnelle, disponible pour r\u00e9aliser des simulations de dynamique mol\u00e9culaire de pointe avec un mod\u00e8le d’\u00e9nergie polarisable \u00e0 haute r\u00e9solution permettant de mod\u00e9liser les m\u00e9canismes d’infection virale dans les d\u00e9tails les plus r\u00e9alistes.<\/p>\n

Le supercalculateur Jean Zay con\u00e7u par HPE et inaugur\u00e9 en janvier 2020 a \u00e9t\u00e9 acquis par GENCI (Grand Equipement National de Calcul Intensif), l’agence fran\u00e7aise de calcul intensif, et est exploit\u00e9 au sein de l’IDRIS (Institut du D\u00e9veloppement et des Ressources en Informatique Scientifique), le plus grand centre d’IA et de simulation num\u00e9rique du CNRS.<\/p>\n
