WebRDM Associates is the premier accounting firm for nonprofit organizations in Michigan. WebAu début, il n'y avait pas de NVLink à l'intérieur de la machine unique, pas de RDMA sur le réseau et la bande passante était relativement faible. Il n'y avait pas beaucoup de différence de bande passante entre la distribution sur une seule machine et la distribution sur plusieurs machines, il suffisait donc de construire un grand anneau.
