Stage 3:
Creating a Cluster
You can create a simple QuickCluster in the Apple Qmaster pane of System Preferences,
or you can create a managed cluster from the service nodes and cluster controller using
Apple Qadministrator. After a cluster is created, client applications on the same network
can start sending batches to the cluster. You can use Apple Qadministrator from any
computer (with Apple Qadministrator installed) that is on the same network as an
Apple Qmaster cluster. See any of the following for more details:

Creating Clusters with Apple Qadministrator
Note: If you are an Apple Qmaster user and you want to create a cluster that includes
computers that do not have Apple Qmaster installed, see the Apple Qmaster User Manual
for instructions.
Configuring Service Nodes and Cluster Controllers
Once service processing or cluster controlling is enabled on a computer, the computer
is advertised on the network as available to be used in a cluster.
Important:
There can be only one cluster controller in a cluster. However, a computer
can be designated as both a cluster controller and a service node (see
to Serve Two Distributed Processing Roles
).
Configuring Service Node Processing
Use the Apple Qmaster pane of System Preferences or Apple Qadministrator to set
processing services on a computer.
To turn on processing services
1
Open the Apple Qmaster pane of System Preferences.
2
Optionally, you can configure a number of settings before you turn on the processing
services. (See
Scheduling Service Availability
.)
Note: It’s easiest to do this now because you can’t configure these settings when
processing services are enabled. To configure these settings after services have been
enabled, you need to turn off the services, configure the settings, and then turn the
services on again.

In the “Share this computer as” section, select one of the following buttons:
• QuickCluster with services: Select this option to create an “instant” cluster with
unmanaged services. (See
for more information.)
