A system and method for allocating computing resources. The system obtains a current set of connections from the matrix switch and then renders a display which reflects the current state of the connections. Source and destination ports are displayed as icons with each icon bearing a label that describes the corresponding source or destination. In some embodiments, a user clicks on a source icon and drags it onto a destination icon to route a particular source to a destination. Dragging a source icon off of a destination icon breaks the connection between the source and destination. The display uses a variety of icons, colors, and grouping schemes to indicate other attributes of the ports, such information regarding X Server configuration, physical location of destination devices, and user login sessions.
