Returns the number of subgroups that the current workgroup is divided into.

uint get_enqueued_num_sub_groups ()


Returns the same value as that returned by get_num_sub_groups if the kernel is executed with a uniform work-group size. If the kernel is executed with a non-uniform work-group size, returns the number of sub groups in each of the work groups that make up the uniform region of the global range.
