I appreciate the following update/response. I was looking into tackling Infiniband technology/configuration for the first time as well. But I was wondering how the Master node was going to communicate effeciently with the other systems. I did not want to invest in an additonal HCA in the master node if there was another possible configuration. Eg my current master node will not have any GPU's in the system; however it does have x4 ethernet ports. However the infiniband switch does not have any ethernet ports at all.
From what I see above and know now I should be able to configure another Ubuntu VM as the cluster master to configure all the jobs.

The broker node is essentially the cluster master – it is the system that controls all the other nodes in the cluster. It does not need to have any GPU devices installed, and it should not have the AMD Catalyst driver installed. This node can be just about anything – even a virtual machine – as long as it has at least 8GB of RAM. It is the only node that you will interact with directly.
