Clusters
When a client sends batches to the Apple Qmaster distributed processing system, all the
processing and subsequent moving of any output files is performed by a group of
Apple Qmaster–configured computers called a cluster. You can create one or more clusters
of service nodes, with one cluster controller included in each cluster. Each computer in
the cluster is connected to the other computers in the cluster through a network
connection.
