FYI, this is what we heard back from the Mellanox folks: I think, issue could be because of older MXM (part of MOFED) being used. We can ask him to try latest MXM from HPCX (http://bgate.mellanox.com/products/hpcx) — Pavan

MXM is part of the Mellanox OFED stack, which is not used on Triolith. Please note that NSC recommends using Intel MPI when possible.

You can install MXM on the vanilla OFED, even without Mellanox OFED. I don’t know why it’s failing to detect the network adapter, though. I’ve pinged the Mellanox folks to see if they can help.

Of course, the Intel MPI is installed and available. However, since Intel MPI is based on MPICH, it suffers from the same problems as MPICH does.

Right. Intel folks occassionally do release updates. For the next update, we’ll ask them to make sure to pick up this patch. But it’s going to be a few months out.
