[Beowulf] How to debug error with Open MPI 3 / Mellanox / Red Hat?

[Faraz Hussain]

Thanks. Before I go down the path of installing things willy-nilly, is  
there some guide I should be following instead? I obviously have a  
problem with my mellanox drivers combined with "user error"..

So should I be paying Mellanox to help? Or is it a RedHat issue? Or is  
it our harware vendor, HP who should be involved??

Looks like I need support on how to get support :-)
