Hello all.
we have here a setup of Infiniband nodes, grouped around IB switches. I wonder if it's possible to have MPI jobs run on a set of nodes that are connected on the *same* IB switch. I thought about special attributes for the nodes, but it is by no way dynamical. Let me be more precise : - we have 64 nodes, connected by groups of 4 nodes per chassis. - we have 4 "leaves" IB switches, all receiving 16 nodes (4 chassis) IB plugs. ... and 2 more spine IB switches. We want the jobs fitting on 16 nodes to run on a set of nodes all connected to the same leaf switch. Does anyone have already configured such a setup ?
