Preparing a Network for Distributed Processing
Example of a Minimal Distributed Processing Network
A very small distributed processing setup could include as few as two computers:
 One computer connected to the client and configured to act as both the service
node and the cluster controller
 One client computer
Though simple, this setup is useful in a small-scale environment because it allows the
client computer to off-load a lot of processing work.
See “
Example of an Expanded Distributed Processing Network
” on page 24 for an
illustration of a more powerful setup.

Using One Computer to Serve Two Distributed Processing Roles
To maximize your resources, you may want to consider using some computers for
more than one distributed processing function.
 Service node and cluster controller: In a small setup, one of the service nodes in a
cluster can also act as the cluster controller so that it performs both functions.
However, in a cluster of many service nodes, the processing load required for the
cluster controller could be so high that it would not be efficient to use one
computer as both a service node and a cluster controller.
 Client computer and cluster controller or service node: You could also set up a client
computer to act as a cluster controller or service node in a cluster, but again, keep
in mind that the more available processing power a computer has, the faster it can
manage or process jobs.
