What is the parallel parameter used for in datapump? If there is just one .dmp file can you still use the parallel parameter?

Controlling Resource Consumption
The Data Pump Export and Import utilities enable you to dynamically increase and decrease resource consumption for each job. This is done using the PARALLEL parameter to specify a degree of parallelism for the job. (The PARALLEL parameter is the only tuning parameter that is specific to Data Pump.) For maximum throughput, do not set PARALLEL to much more than twice the number of CPUs (two workers for each CPU).

The docs.  Just a different one:

You can supply multiple file_name specifications as a comma-delimited list or in separate DUMPFILE parameter specifications. If no extension is given for the filename, then Export uses the default file extension of .dmp. The filenames can contain a substitution variable (%U), which implies that multiple files may be generated. The substitution variable is expanded in the resulting filenames into a 2-digit, fixed-width, incrementing integer starting at 01 and ending at 99. If a file specification contains two substitution variables, both are incremented at the same time. For example, exp%Uaa%U.dmp would resolve to exp01aa01.dmp, exp02aa02.dmp, and so forth.
