Message definition (Narval)
==Réseautique haute performance==
Le réseau [https://fr.wikipedia.org/wiki/Bus_InfiniBand InfiniBand] [https://www.nvidia.com/en-us/networking/infiniband/qm8700/ HDR de Mellanox] relie tous les nœuds de la grappe. Chaque commutateur de 40 ports HDR (200 Gb/s) permet de connecter ensemble jusqu'à 66 nœuds en HDR100 (100 Gb/s) avec 33 liens HDR divisés en deux (2) par des câbles spéciaux. Les sept (7) liens HDR restants servent à connecter le commutateur d'un cabinet à chacun des sept (7) commutateurs HDR du réseau InfiniBand central. Les îlots de nœuds sont donc connectés avec un facteur de blocage maximum de 33:7 (4.7:1). Par contre, les serveurs de stockage sont branchés avec un facteur de blocage significativement plus bas pour une performance maximale.

High-performance interconnect

The InfiniBand Mellanox HDR network links together all of the nodes of the cluster. Each hub of 40 HDR ports (200 Gb/s) can connect up to 66 nodes with HDR100 (100 Gb/s) with 33 HDR links divided in two (2) by special cables. The seven (7) remaining HDR links allow the hub to be connected to a rack containing the seven (7) central HDR InfiniBand hubs. The islands of nodes are therefore connected by a maximum blocking factor of 33:7 (4.7:1). In contrast, the storage servers are connected by a much lower blocking factor in order to maximize the performance.
