Public Members

void *d_temp_storage

Device-accessible allocation of temporary storage.

When nullptr, the required allocation size is written to temp_storage_bytes and no work is done.

size_t &temp_storage_bytes

Reference to size in bytes of d_temp_storage allocation.

KeyInputIteratorT d_input_keys

Pointer to the input sequence of unsorted input keys.

ValueInputIteratorT d_input_items

Pointer to the input sequence of unsorted input values.

KeyIteratorT d_output_keys

Pointer to the output sequence of sorted input keys.

ValueIteratorT d_output_items

Pointer to the output sequence of sorted input values.

OffsetT num_items

Number of items to sort.

CompareOpT compare_op

Comparison function object which returns true if the first argument is ordered before the second.

cudaStream_t stream

CUDA stream to launch kernels within. Default is stream₀.

int ptx_version

KernelSource kernel_source

KernelLauncherFactory launcher_factory

Public Static Attributes

static constexpr bool KEYS_ONLY = ::cuda::std::is_same_v<ValueT, NullType>

Whether or not there are values to be trucked along with keys.
