The management module needs some software to manage the cluster. I'll detail setting up NFS and TFTP to boot the nodes and get MPICH2 running in a later post because it's fairly involved.

I put the code for my management interface on GitHub here https://github.com/calston/tinyjaguar

This provides simple control for the ATX power supply, and makes the buttons and LED's do the right things.

Just for fun I added in a little isometric view of the cluster which updates in real time according to the temperature of each node which is somewhat hypnotic to watch, especially when I apply load and it starts warming up and turning green and then yellow. The ambient temperature today is pretty cold in my lab, seems Winter Is Comming.
