Apple Qmaster 2 and Compressor 2 (Distributed Processing Setup) - Manual (Page 40)

40 Chapter 4 Creating and Administering Clusters
An Overview of Configuring a Cluster
Assuming Apple Qmaster software is installed on all the computers that you plan to
use as part of the cluster, there are three basic steps involved in configuring a cluster.
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 2 User
Manual for instructions.
Step 1: Configure service nodes
Configuring a service node to perform distributed processing is a matter of turning on
processing services in the Apple Qmaster pane in System Preferences. Optionally, you
can also set passwords at this time. See “
Configuring Service Nodes and Cluster
Controllers ,” below, for details.
Step 2: Configure a cluster controller
To configure a computer to control the cluster, turn on the cluster control services in
the Apple Qmaster pane in System Preferences. See “
Turning Cluster Controller Services
On or Off ” on page 45 for more information.
Step 3: Create a cluster
You can create a simple “QuickCluster” in the Apple Qmaster pane in 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:
 “ Getting Started Quickly ” on page 15
 “ Creating QuickClusters ” on page 50
 “ Creating Clusters With Apple Qadministrator ” on page 48
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.
There can only be one cluster controller in a cluster. However, a computer can be
designated as both a cluster controller and a service node (see “
Using One Computer
to Serve Two Distributed Processing Roles ” on page 22).
