Weasel has 1 head node and 50 slave nodes each with 2 Pentium III 1GHz processors.
The head node, slave nodes, network switch, monitor/keyboard/mouse, and power strips are all contained and mounted to two midpoint rack units.
The power is dispersed across six 20amp circuits, and in a conditioned room with two 5 ton air conditioning units (heat,cool,humidity). Room is set to approx. 65degF and 55% RH.
Look at the installation photo-log to
