Since these ports are running in actual Ethernet mode (as opposed to
IPoIB), I do not think the interface names will be of the ibN (ib0,
ib1, etc) format. It is more likely that the interface names will be
of the form ethN or enPApBsCfD.
It would be best to check with your system administrator, bu
Thanks Gus. I'll try and post results.
I am newbie in this and appreciate any advice very much.

Hi Boris
The nodes may have standard Gigabit Ethernet interfaces,
besides the Infiniband (RoCE).
You may want to direct OpenMPI to use the Infiniband interfaces,
not Gigabit Ethernet,

Thanks very much for the replies and the help.
I got confirmation from the "root" that it is indeed RoCE with 100G.
I'll go over the info in the link Russell provided, but have a quick
question: if I run the "*mpiexec*" with "*-mca btl tcp,self*" do I get the

It looks like you have two dual-port Mellanox VPI cards in this
machine. These cards can be set to run InfiniBand or Ethernet on a
port-by-port basis, and all four of your ports are set to Ethernet
mode. Two of your ports have active 100 gigabit Ethernet links, and
the other two have no link up at
Boris,
these logs seem a bit odd to me.
as far as i remember, the state is POLLING when there is no subnet manager.
and when there is one, the state is ACTIVE *but* both Base and SM lid
are non zero
btw, is IPoIB configured ?
if yes, then can your hosts ping each other with this interface.
i not
Boris,
do you have a Subnet Manager running on your fabric?
I am sorry if there have bene other replies ot this over the weekend.
