Tells the auto-parallelizer to generate multithreaded code for loops that can be safely executed in parallel. This feature is only available for ifort.

Multithreaded code is not generated for loops that can be safely executed in parallel. |
This option tells the auto-parallelizer to generate multithreaded code for loops that can be safely executed in parallel.
To use this option, you must also specify option O2 or O3.
This option sets option [q or Q]opt-matmul if option O3 is also specified.
Using this option enables parallelization for both Intel® microprocessors and non-Intel microprocessors. The resulting executable may get additional performance gain on Intel microprocessors than on non-Intel microprocessors. The parallelization can also be affected by certain options, such as /arch or /Qx (Windows*) or -m or -x (Linux* and macOS*).
