Let's say you have a brand new cluster with
brand new Infiniband hardware, and that
you've installed OFED 1.4 and the
appropriate drivers for your IB
HCAs (i.e. you see ib0 devices
on the frontend and all compute nodes).
The cluster appears to be working
fine but you're not sure about IB.

How would you test your IB network
to make sure all is well?
