cub::AgentRadixSortHistogramPolicy

template<int _BLOCK_THREADS, int _ITEMS_PER_THREAD, int NOMINAL_4B_NUM_PARTS, typename ComputeT, int _RADIX_BITS>
struct AgentRadixSortHistogramPolicy

Public Types

enum [anonymous]

Values:

enumerator BLOCK_THREADS = _BLOCK_THREADS

enumerator ITEMS_PER_THREAD = _ITEMS_PER_THREAD

enumerator NUM_PARTS = cuda::std::max(1, NOMINAL_4B_NUM_PARTS * 4 / cuda::std::max(int{sizeof(ComputeT)}, 4))

NUM_PARTS is the number of private histograms (parts) each histogram is split into.

Each warp lane is assigned to a specific part based on the lane ID. However, lanes with the same ID in different warp use the same private histogram. This arrangement helps reduce the degree of conflicts in atomic operations.

enumerator RADIX_BITS = _RADIX_BITS
