Intel® C++ Compiler 19.0 Developer Guide and Reference
Lets you select between old or new implementations of parallel loop support.
Linux and macOS: | -par-loops=keyword |
Windows: | /Qpar-loops:keyword |
keyword |
Specifies which implementation to use. Possible values are:
|
-par-loops=old or /Qpar-loops:old |
The compiler uses the old implementation of parallel-loop support, the same one used in previous releases of the compiler. |
This option lets you select between old or new implementations of parallel loop support.
The new implementation handles parallel C++ range-based loops, and also collapsing of OpenMP* parallel loops with complicated bounds expressions, for which the previous implementation reported errors.
If your code has a parallel loop that is not handled by the previous implementation, we recommend that you enable use of the new implementation.
