Message definition (Narval)
En pratique, les cabinets de Narval contiennent des îlots de 48 ou 56 nœuds CPU réguliers. Il est donc possible d'exécuter des tâches parallèles utilisant jusqu’à 3584 cœurs et une réseautique non bloquante. Pour des tâches plus imposantes ou plus fragmentées sur le réseau, le facteur de blocage est de 4.7:1. L’interconnexion reste malgré tout de haute performance.

In practice the Narval racks contain islands of 48 ou 56 regular CPU nodes. It is therefore possible to run parallel jobs using up to 3584 cores with a non-blocking network. For larger jobs or ones which are distributed in a fragmented manner across the network, the blocking factor is 4.7:1. The inter-connect remains a high-performance one nonetheless.
