cuda::experimental::make_hierarchy

Defined in include/cuda/experimental/__hierarchy/hierarchy_dimensions.cuh

template<typename L1, typename ...Levels>
constexpr auto cuda::experimental::make_hierarchy(L1 l1, Levels... ls) noexcept

Creates a hierarchy from passed in levels.

This function takes any number of level_dimensions or derived objects and creates a hierarchy out of them. Levels need to be in ascending or descending order and the lowest level needs to be valid for thread_level unit. To create a hierarchy not ending with thread_level unit, use make_hierarchy_fragment instead.

auto hierarchy2 = make_hierarchy(block_dims<8, 8, 8>(), cluster_dims<4>(), grid_dims(256));
static_assert(cuda::std::is_same_v<decltype(hierarchy1), decltype(hierarchy2)>);
