Computers that submit batches to the Apple Qmaster distributed processing system are
called clients. A job is a processing task such as a Compressor preset-source pair, or a
Shake file, or other files or commands that use UNIX commands to specify settings such
as rendering instructions and file locations and destinations.

A batch is one or more jobs submitted for processing at one time. The procedure is
analogous to printing multipage documents from a word processing program; the files
are spooled and processed in the background. Although a batch can include just one
job, you will typically want to submit several jobs at once for processing. Similarly, several
people can use the same Apple Qmaster system at the same time, with several client
computers sending batches in the same time frame. Batches are managed and distributed
by the computer that is designated as the Apple Qmaster cluster controller, which is
described in the next section.
There are three approaches you can take toward setting up a distributed processing
system:
Note: All three approaches also produce either service nodes (used by the This Computer
Plus option in the Final Cut Pro and Motion Share menu items) or clusters that the
Final Cut Pro and Motion Share function can use to process output files.
• Use This Computer Plus: Using This Computer Plus is the easiest approach you can take
to create a distributed processing system. You simply install Compressor, configured
as a service node, on any computers you want to perform processing duties. For more
information, see Getting Started Quickly Using This Computer Plus.
• Create a QuickCluster: Creating a QuickCluster allows you to configure a single computer
to be a cluster by choosing the number of instances it supports, based on the number
of cores available. For more information, see Getting Started Quickly Using QuickClusters.
