3.6.8 omp_is_initial_device – Whether executing on the host device ¶

Description:

This function returns true if currently running on the host device, false otherwise. Here, true and false represent their language-specific counterparts.

Note that in GCC this function call is already folded to a constant in the compiler; compile with -fno-builtin-omp_is_initial_device if a run-time function is desired.

C/C++:

Prototype:

int omp_is_initial_device(void);

Fortran:

Interface:

logical function omp_is_initial_device()

Reference:

OpenMP specification v4.5, Section 3.2.34.
