Configuration files for clusters requires some additional configuration options to be set in order to cause the CAVELib application to run in cluster mode. There are settings for both the master node and slave nodes.These additional options can be appended to the end of each machine specific (HOST.config) configuration file. The id's will change for each node and number of nodes is dependent upon the cluster setup. And the hostname of the master node is the node that is designated with id 0, and it must also be the system that is running trackd if trackers and controllers are being used.
