Subject: [OMPI users] Different Interfaces on Different Nodes .. OpenMPI 1.2.3, 1.2.4 ..
From: Graham Jenkins (Graham.Jenkins_at_[hidden])

We're moving from using a single (eth0) interface on our execute nodes
to using a bond interface (bond0) for resilience.
And what we're seeing on those nodes which have been upgraded is:

invalid interface "eth0"
This of course, is because all nodes share a common copy of
openmpi-mca-params.conf .. in which its says:
So .. does anybody have a suggestion for a way around this during our
migration/upgrade period?
If we place "bond0" in there as well, then we get error messages about
whichever one is absent on the node where execution is happening.
