Preface
 
    Introduction to Distributed Processing
 
 
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 file 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 multi-page 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.
 
Basic Components of the Apple Qmaster Distributed 
Processing System
 
While the Apple Qmaster software includes a few different applications (see Chapter 3, 
,” on page 31), as a whole it is part of a networked system that includes 
the following basic components:
Â
 
Client(s):
 
  The computer or computers that use Compressor or Apple Qmaster to 
submit jobs for distributed processing. Applications that can use Apple Qmaster 
services for processing include Compressor, Shake, Alias Maya, and many UNIX 
command-line programs.
