OMP_DISPLAY_ENV – Show OpenMP version and environment variables ¶If set to TRUE, the runtime displays the same information to
stderr as shown by the omp_display_env routine invoked with
verbose argument set to false. If set to VERBOSE, the same
information is shown as invoking the routine with verbose set to
true. If unset or set to FALSE, this information is not shown.
The result for any other value is unspecified.
