Parallel Compilation
Allows you to specify the number of processors the Quartus® Prime software can use at once to run parallel executables, which reduces total processing time.
When you run any Compiler module with parallel compilation enabled, the Parallel Compilation report lists the number of processors it detects, the average processor use, the maximum processor use, and the time the Compiler uses each processor.
Parallel compilation is set to Use global compilation setting by default.
- Use global parallel compilation setting—Sets Parallel compilation to the setting specified under Parallel compilation in the Processing page of the Options dialog box.
- Use all available processors—Specifies that the Quartus® Prime software uses all available processors to run parallel executables.
- Maximum processors allowed—Specifies the number of processors
parallel executables can use on a single machine at the same time. For example, if
you have a quad-core processor machine and want to leave one processor free for other
tasks, you would specify
3as the setting of this option. Setting this option to1effectively disables parallel compilation.
Important: Important: Setting this option to a
number higher than the number of physical processors in your system
may degrade the performance of the
Quartus® Prime software by creating
more than the optimal number of threads.
