Hello Howard,
Here is the error output after building with debug enabled. These CX4 Mellanox
cards view each port as a separate device and I am using port 1 on the card
which is device mlx5_0.

Hello Brendan,
This helps some, but looks like we need more debug output.
Could you build a debug version of Open MPI by adding --enable

Hi Brendan
I doubt this kind of config has gotten any testing with OMPI. Could you rerun
with
--mca btl_base_verbose 100
added to the command line and post the output to the list?

Hello,
I am attempting to get Open MPI to run over 2 nodes using a switch and a
single breakout cable with this design:
(100GbE)QSFP <> 2x (50GbE)QSFP
Hardware Layout:
Breakout cable module A connects to switch (100GbE)
Breakout cable module B1 connects to node 1 RoCE NIC (50GbE)
