Grappes de calcul

Les grappes d'usage général sont conçues pour l'exécution de plusieurs types de tâches. Elles sont composées de nœuds qui présentent des caractéristiques différentes et que nous classons selon trois groupes :

base nodes qui ont typiquement environ 4Go de mémoire par cœur;
large-memory nodes qui ont typiquement plus de 8Go par cœur;
nœuds GPU qui ont des processeurs graphiques.

The large parallel cluster Niagara is designed to support multi-node parallel jobs requiring more than 1000 CPU cores, although jobs as small as a single node are also supported there. Niagara is composed of nodes of a uniform design, with an interconnect optimized for large jobs.

All clusters have large, high-performance storage attached. For details about storage, memory, CPU model and count, GPU model and count, and the number of nodes at each site, please see the individual cluster pages linked under "Resources" at left.
