We have a cluster with nodes connected by FDR IB and with 2 Intel Phis per node.
Some basic Q:
To support "symmetric" Intel Phi compute mode (some MPI ranks on Phi cores some on xeon cores), I need to define the "external Bridge" networking, correct?
We have to define the "bridge" br0 i/f on each node, but do we change anything with the IP addressing of the main networking i/f (say) eth0 ?
thanks
