Service Nodes
When you combine multiple nodes into a cluster, they function as one very powerful
computer because all their resources are shared. You make a computer available as a
service node by configuring it in the Apple Qmaster pane in System Preferences. The
steps involved in using System Preferences to configure a service node are described in
“Creating and Administering Clusters” in the
Distributed Processing Setup guide.
Cluster Controllers
The cluster controller software acts as the manager of a cluster. The cluster controller
directs the distribution of batches within the cluster. It has the ability to determine the
best use of the cluster resources based on work and availability variables. (See the
Distributed Processing Setup guide for more details.) You make a computer available as
a cluster controller by turning on the cluster controlling service in the Apple Qmaster
pane in System Preferences. (See “Configuring Service Nodes and Cluster Controllers,”
in the
Distributed Processing Setup manual.)
The Apple Qmaster Interface
The Apple Qmaster application described in this document is one part of the larger
distributed processing system described above. The Apple Qmaster application is the
client software you use to submit jobs and batches to the system. Both this application
and the larger system are known by the same name (Apple Qmaster).
The Apple Qmaster window contains a toolbar, a Batch Name field; a Submit To field;
the Batch table; buttons to add, remove, and submit jobs (dimmed until at least one
job is in the Batch table); and pop-up menus to choose job types and batch priority.
