The Ultimate Linux Lunchbox
 

In this article, we describe the construction of the Ultimate Linux Lunchbox, a 16-node cluster that runs from a single IBM ThinkPad power supply but can, as well, run from an N-charge or similar battery. The lunchbox has an Ethernet switch built-in and has only three external connections: one AC plug, one battery connector and one Ethernet cable. To use the lunchbox with your laptop, you merely need to plug the Ethernet cable in to the laptop, supply appropriate power-even the power available in an airplane seat will do-and away you go, running your cluster at 39,000 feet. We've designed the lunchbox so that we can develop software on it, as a private in-office cluster or a travel cluster. The lunchbox is an example of a newer class of clusters called miniclusters.
