Apple Qmaster 4 - Manual (Page 30)

Will Your Cluster Include Only Extended Nodes or Be Mixed?
If all the nodes in the cluster will be extended nodes (nodes that do not have Compressor
installed), the cluster needs one intermediary node that also acts as the cluster controller.
There is no need to use the Apple Qadministrator application at all if you are creating a
cluster that contains only an intermediary node and extended nodes. All the configuration
can be done in the Apple Qmaster Sharing window in Compressor, as described in
Configuring an Intermediary Node for an Extended Node Cluster .
However, if you want a cluster that contains both regular service nodes and extended
nodes, configure an intermediary node (as described in
Configuring an Intermediary Node
for an Extended Node Cluster ), and then add it to a regular cluster that already has a
cluster controller. (There can be only one cluster controller per cluster.)
Configuring an Intermediary Node for an Extended Node Cluster
Before you begin, make sure that:
• The computer that will be the intermediary service node has Compressor installed
• The computers that will be the extended nodes have a UNIX-based operating system
and have SSH enabled
To configure an intermediary service node to run Apple Qmaster commands on
extended nodes
1 Open the Apple Qmaster Sharing window in Compressor.
2 If this intermediary node will be part of a mixed cluster, with a different computer acting
as the cluster controller, skip this step and go to step 3. If you want this intermediary
node to be the cluster controller for this cluster, do the following:
a Select the “Share this computer” checkbox, then select one of the following buttons:
• “as QuickCluster with services”
• “as Services and cluster controller”
For more information on creating cluster controllers, see the “Apple Qmaster and
Distributed Processing” chapter in the Compressor User Manual.
b Enter a name in the “Identify this QuickCluster as” field. This is the name you will see
in the Cluster list in Apple Qadministrator and in the cluster pop-up menus in Share
Monitor and Apple Qmaster.
3 Select the Rendering and “Require these services to only be used in managed clusters”
checkboxes.
4 Click the Options button next to the Rendering item.
