3.4.1 omp_get_num_threads_dim – Size of a dimension of the active team ¶

Returns the size in dimension DIM of threads in the current team and, therefore, of the parallel region that binds to that team, i.e. the value of the team-size-var ICV in dimension dim. For inactive spatial dimensions, the routine returns 1. The dimension argument DIM must be non-negative.

Fortran note: In GCC, this routine does not support passing default-kind integer arguments with -fdefault-integer-8.

C/C++:

Prototype:

int omp_get_num_threads_dim(int dim)

Fortran:

Interface:	integer function omp_get_num_threads_dim(dim)
	integer :: dim
