A computer cluster is a group of linked computers working closely together so that in many respects they form a single computer. Often clusters are used for primarily computational purposes. For instance, a cluster might support computational simulations of weather or vehicle crashes. Cluster computing is also very important for the movie industry, particularly for animation.
With our new Mobile Cluster (4x Intel Xeon Dual Core CPUs, Linux powered) we are able to demonstrate how image rendering can be distributed onto a cluster. In our demo, a digital picture of the interested visitor will be made with an off-the shelf webcam. Then the cluster will render it onto a rotating coffee cup. The result is a movie which shows the rotating cup with the picture of the tester on it.
