Parallel Processing Options
This command supports the following options:
Option Page
-p[=on|off].............................................................................................................................................. 2–97
--parallel[=]............................................................................................................ 2–97
-p[=on|off]
Enables parallel compilation. The Quartus II software uses all processors detected on the system.
This option is equivalent to specifying the --parallel option without any arguments.
--parallel[=]
Controls parallel compilation.
If specified without an option, the Quartus II software uses all processors detected on the system.
Otherwise, the software attempts to use the specified number of processors. If the specified number is
more than the number of processors that actually exist on the system, runtime may increase.
The default value is 1, which disables parallel compilation.
