OMP_SET_NESTED

Purpose:

Used to enable or disable nested parallelism.

Format:

Fortran

SUBROUTINE OMP_SET_NESTED(scalar_logical_expression)

C/C++

#include <omp.h>
void omp_set_nested(int nested)

Notes & Restrictions:

• For Fortran, calling this function with .FALSE. will disable nested parallelism, and calling with .TRUE. will enable it.

• For C/C++, if nested evaluates to non-zero, nested parallelism is enabled; otherwise it is disabled.

• The default is for nested parallelism to be disabled.

• This call has precedence over the OMP_NESTED environment variable
