Which hardware should I concentrate on, when assembling a head node for an HPC cluster? The main task for the head node is to relay instructions to the compute nodes which will be running artificial intelligence algorithms.
Ubuntu 14.04 LTS will be running on the head node.
I would assume it should have a high bandwidth NIC such as the infiniband 50 Gbps card, but I'm relatively inexperienced in this area.
Thank you
