Subject: [OMPI users] IPoIB
From: David Turner (dpturner_at_[hidden])

Hi all,

Please, some clarification. I have built Open MPI 1.4.1 against
our IB verbs layer, and all seems well. But a question has come
up about IPoIB. While all communications are using the "native"
IB interface (verbs), will mpirun use IPoIB during job launch
and teardown?

If it matters, resource allocation is via torque.

Thanks!
