4 Optionally, do one of the following to start the Apple Qmaster processes:
 Enter this command:
sudo SystemStarter start Qmaster
 Restart the remote computer.
5 Repeat these steps for each computer in your distributed processing network.
You can also install Apple Qmaster using Apple Remote Desktop. Just select a node, click
Install Package, and select the standalone installer package (AppleQmasterNode.mpkg).
The copy and installation process is done automatically.
Shell Commands for Configuring Service Nodes and Cluster Controllers
As an alternative to using the Apple Qmaster pane in System Preferences, you can use
the command qmasterprefs, with command-line options for enabling and disabling
service node and cluster-controlling services.
In the command-line descriptions below, angle brackets < > indicate a mandatory
argument in a command and brackets [ ] indicate an optional argument.
Note: While it is possible to use the command line to run an Apple Qmaster distributed
processing network, each Compressor service node (each computer providing
Compressor distributed processing services) must be logged in (with a Mac OS X
user name and password) for full functionality.
