Creating A Configuration File

Suppose you have a distributed display such as that pictured above. It has 4 screens, each connected to a different computer. Each screen has a resolution of 400X400 pixels. Furthermore, assume that the bezels of the screens are about an inch thick, and that you could fit about 50 pixels in the bezels. Hence, the mullionWidth and mullionHeight. The computers hostnames are c1,c2,c3, and c4. c1 is the bottom left, c2 the bottom right, c3 top left, c4 top right. You also intend to have a master process running on a local screen, on host localhost.

• numTilesWidth = 2, numTilesHeight = 2
• screenWidth = 400, screenHeight = 400
• mullionWidth = 50, mullionHeight = 50

The configuration file would look like this for the display above:

The configuration file has a element for each display. In the case that there might be a computer driving two monitors, you might have two elements for that process, and one of the elements would have x and y offsets.
