Hi all -

I have been using OpenMPI for quite a while now, and its working out great.
I was looking at the FAQ and trying to figure out how to configure OpenMPI
with infiniband. It shows how to enable IB pointing to the OFED directory.

I have infiniband built into the kernel, along with IP over IB and with the
Mellanox drivers. What would I still need to install, and how would I
configure OpenMPI to work with this?
