Utiliser les noeuds infiniband pour des transferts plus rapides:<\/h2>\n

R\u00f4le de l'Infiniband :<\/h3>\n

Le r\u00e9seau Infiniband(192.168.4.0) permet aux utilisateurs d'avoir acc\u00e8s \u00e0 un r\u00e9seau haut d\u00e9bit pour transf\u00e9rer leurs donn\u00e9es depuis le san vers les nodes et inversement ou entre les noeuds infiniband\u00a0 .<\/p>\n

Seulement certains noeuds dans la liste ci-dessous sont \u00e9quip\u00e9s d'infiniband pour le moment :\u00a0 <\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

R\u00e9server un noeud Infiniband:<\/h3>\n

Pour utiliser le r\u00e9seau infiniband, il suffit d'ajouter le suffixe -ib<\/strong> \u00e0 l'alias de la machine \u00e0 connecter, par exemple san deviendra san-ib et node0 deviendra node0-ib etc ...<\/p>\n

Utilisez les options\u00a0 \u00a0 -p partition<\/em> ( avec partition la partition du noeud de calcul) --constraint=infiniband<\/em> pour r\u00e9server un ou plusieurs coeurs d'un noeud infiniband. ( cf feature page<\/a> pour plus d'explications) <\/p>\n

Par exemple nous voulons r\u00e9server un noeud infiniband sur la partition highmem en mode int\u00e9ractif, taper la commande suivante:<\/p>\n

srun -p highmem --constraint=infiniband --pty bash -i <\/code><\/p>\n

Vous \u00eates d\u00e9sormais sur un noeud qui a acc\u00e8s au r\u00e9seau infiniband, pour l'utiliser, modifiez juste l'alias san en san-ib pour faire vos transferts.<\/p>\n

Transfert avec Infiniband:<\/h3>\n

Il y a 2 syntaxes possibles:<\/p>\n

R\u00e9cup\u00e9rer des donn\u00e9es depuis le san:<\/h4>\n

scp -r san-ib:path_to_files\/file local_destination<\/code><\/p>\n

Envoyer des donn\u00e9es vers le san:<\/h4>\n

scp -r \/local_path_to_files\/file san-ib:remote_destination<\/code><\/p>\n","protected":false},"excerpt":{"rendered":"
