Distributed Processing Setup Guide

• Cluster Storage button: Enter a local folder directory to change the scratch location for
the cluster’s temporary process files. See Using Cluster Storage for more information.
Network
Use these features to configure network settings.
• “Allow discovery via Bonjour” checkbox: By default, this checkbox is selected to have the
Apple Qmaster distributed processing system use the Bonjour networking technology.
You can deselect the “Allow discovery via Bonjour” checkbox for enhanced security.
This will prevent detection of your computer over a Bonjour network. This feature
requires Mac OS X v10.4 or later.
• “Use Network Interface” pop-up menu: Restrict distributed processing activity to a
particular network interface card by choosing it from this pop-up menu. If you do this
on a service node computer, use a different computer to submit Compressor jobs and
batches.
• “Enable Port Range” checkbox and fields: You can define which ports Apple Qmaster
uses for service advertisements with the Enable Port Range checkbox and text fields
in the Network section of the Advanced pane within the Apple Qmaster pane of System
Preferences. For more information, see Defining Ports for Service Advertisements.
Extras
Use these features to configure additional settings.
• “Log service activity to file” checkbox: If this checkbox is selected, an activity log is created
and updated regularly with information about the Apple Qmaster actions on this
computer. Logs are stored in /Library/Logs/Qmaster/. To turn this feature off, deselect
the checkbox.
Note: You can also access this log information using the Log button in
Apple Qadministrator or the Log tab in Batch Monitor.
• “Show Apple Qmaster service status in menu bar” checkbox: If this checkbox is selected,
an Apple Qmaster icon appears in the computer’s menu bar. The menu bar item provides
Apple Qmaster status and activity information. For more information, see Service Node
Status Indicator in the Menu Bar.
• “Identify this computer to Qadministrator as” field: By default, a computer is identified
on the network by its computer name (as it is entered in the Sharing pane of System
Preferences). You can change this name to something more meaningful if you like,
since it is the name used to identify this computer in the Apple Qadministrator
application. If you are setting up a managed cluster controller, this is the name that
will appear in the Apple Qadministrator Controller pop-up menu.
