The hosts or host ranges appear in the Host table in the main Preferences dialog.

Setting Passwords

You can create several types of passwords for the Apple Qmaster distributed processing

system. All these passwords are optional; you can use the system without creating them.

• Cluster administrator password: A password required for modifying a cluster in

Apple Qadministrator, and for modifying the status of the cluster’s batches in

Batch Monitor. See Setting Cluster Administrator and User Passwords.

• Cluster user password: A password that client users need in order to submit batches to

a cluster and to modify the status of those batches in Batch Monitor. See Setting Cluster

Administrator and User Passwords.

• Service password: A password required for an administrator to add a specific service

node or cluster controller to a cluster. See Setting a Service Password for Including a

Computer in a Cluster.

You can also change the default scratch storage location for a cluster, or for each computer

in a cluster. See Using Cluster Storage.

Setting Cluster Administrator and User Passwords

You can create cluster passwords while creating a new cluster, as described in Creating

Clusters with Apple Qadministrator. However, once the cluster is created, you can still

add or change passwords, using the same settings in Apple Qadministrator.

To create or change cluster passwords

1 In Apple Qadministrator, select the cluster from the Cluster list.

2 Click Security.

3 Select and enter or change the passwords you want.

4 Click Apply.

Note: Cluster administrator and cluster user passwords can be stored in a user’s keychain.

Setting a Service Password for Including a Computer in a Cluster

If you want to control who is able to include a specific service node or cluster controller

in a cluster, you can create a password called a service password for the computer.
