Description

This option enables the parallelizer to generate multi-threaded code based on the OpenMP* directives. The code can be executed in parallel on both uniprocessor and multiprocessor systems.

If you use this option, multithreaded libraries are used, but option fpp is not automatically invoked.

This option sets option automatic.

This option works with any optimization level. Specifying no optimization (-O0 on Linux or /Od on Windows) helps to debug OpenMP applications.

Alternate Options
