The -openmp-report (Linux* and Mac OS* X) or /Qopenmp-report (Windows*) option controls the diagnostic levels for OpenMP* reporting. The OpenMP* report information is not generated unless you specify the option with a value of either 1 or 2. Specifying 2 provides the most useful information.
You must specify the -openmp (Linux and Mac OS X) or /Qopenmp (Windows) along with this option.

-openmp-report 2 |
/Qopenmp-report:2 |
Report results are same as when specifying 1 except the results also include diagnostics indicating constructs, like directives, that were handled successfully. This is the recommend level. |
-openmp-report 1 |
/Qopenmp-report:1 |
Reports on loops, regions, and sections that were parallelized successfully. This is the default level. |
-openmp-report 0 |
/Qopenmp-report:0 |
No diagnostics report generated. |
