Use Apple Qmaster to set up a distributed processing system

In the dialog that appears, add an instance for each extended node you want this intermediary

node to send commands to by doing the following:

Choose SSH from the Add (+) pop-up menu.

Edit the Host name, Username, and (if applicable) Password columns so that they describe

each computer you want to use as an extended node, and click OK.

Edit the Host name,

Username, and

Password columns

to specify the extended

nodes you’re adding.

In the Apple Qmaster Sharing window, click OK.

Note: If you’re making changes to existing settings and this computer is already providing
processing services, a window appears warning you that its services must be restarted for the
changes to take effect. You can delay the restart by entering the number of minutes to wait,
which gives you time to warn others or for current batches to finish processing.

If you configured this intermediary node as the cluster controller, your work is done and
the extended node cluster is ready to start receiving and processing batches submitted by
Apple Qmaster.
If, instead, you want the extended nodes to be part of a cluster that includes regular service
nodes, use Apple Qadministrator to add this intermediary node to that cluster. You add an
intermediary node in the same way you add other service nodes. For more information, see

Creating service nodes and cluster controllers overview

on page 222.
