ipo-jobs, Qipo-jobs
Specifies the number of commands (jobs) to be executed simultaneously during the link phase of Interprocedural Optimization (IPO). This feature is only available for ifort.
Syntax
Linux: |
-ipo-jobsn |
macOS: |
-ipo-jobsn |
Windows: |
/Qipo-jobs:n |
Arguments
n |
Is the number of commands (jobs) to run simultaneously. The number must be greater than or equal to 1. |
Default
-ipo-jobs1 |
One command (job) is executed in an interprocedural optimization parallel build. |
Description
This option specifies the number of commands (jobs) to be executed simultaneously during the link phase of Interprocedural Optimization (IPO). It should only be used if the link-time compilation is generating more than one object. In this case, each object is generated by a separate compilation, which can be done in parallel.
This option can be affected by the following compiler options:
[Q]ipo when applications are large enough that the compiler decides to generate multiple object files.
[Q]ipon when n is greater than 1.
[Q]ipo-separate
Be careful when using this option. On a multi-processor system with lots of memory, it can speed application build time. However, if n is greater than the number of processors, or if there is not enough memory to avoid thrashing, this option can increase application build time.
