Direct-Coupled Machines Definition/Meaning:
A system in which two (or more) machines are connected
by a high-speed link in order to perform the total workload. Typically a small
machine, the master, deals with file editing, job submission, and all
scheduling. Larger jobs that would take too long to process on this small
machine are passed to a larger machine, the slave, for processing, the results
being returned to the user via the small machine. See also master-slave machine.
