 Creating and Administering Clusters

 

You have flexibility in how you build clusters for distributed processing with 
Compressor or Apple Qmaster. When you turn on processing services (See “

” on page 48), you can choose to make them either 

managed services or unmanaged services (the default).

Managed services can be assigned to serve one particular cluster controller. Once assigned, 
managed services remain exclusively dedicated to that cluster until they are removed with 
the Apple Qadministrator application. QuickClusters cannot use managed services from 
other nodes, except in the case of extended node clusters. For more information, see 
“

” on page 58. See the 

Apple Qmaster User Manual for more information on extended node clusters.

Unmanaged services will automatically assign themselves to the first available 
QuickCluster with enabled unmanaged services support. QuickClusters listen for 
unmanaged service advertisements and may mark or remember any of them for later 
use. A QuickCluster can use any available unmanaged service on the same local 
network (subnet). An unmanaged service will remain dedicated to its QuickCluster only 
long enough to finish the current job. Once the current job is complete, an unmanaged 
service is once again a “free agent,” and will advertise its availability to all QuickClusters.

Note:  Managed clusters (those created with Apple Qadministrator) can also use 
unmanaged services. When unmanaged services support is enabled on a “managed” 
cluster, the cluster will automatically add any available unmanaged services in addition 
to its managed services (that were explicitly added using Apple Qadministrator).
