cuda::experimental::distribute

template<int _ThreadsPerBlock>
constexpr auto cuda::experimental::distribute(

int numElements,

) noexcept

A shorthand for creating a kernel configuration with a hierarchy of CUDA threads evenly distributing elements among blocks and threads.

Snippet

#include <cudax/hierarchy_dimensions.cuh>
using namespace cuda::experimental;

constexpr int threadsPerBlock = 256;
auto dims = distribute<threadsPerBlock>(numElements);

// Equivalent to:
constexpr int threadsPerBlock = 256;
int blocksPerGrid = (numElements + threadsPerBlock - 1) / threadsPerBlock;
auto dims = make_hierarchy(grid_dims(blocksPerGrid), block_dims<threadsPerBlock>());
