cub::ScanTileState< T, true > Struct Template Reference

Detailed Description

template<typename T>
struct cub::ScanTileState< T, true >

Tile status interface specialized for scan status and value types that can be combined into one machine word that can be read/written coherently in a single access.

Member Function Documentation

◆ AllocationSize()

template<typename T >
__host__ __device__ static __forceinline__ cudaError_t cub::ScanTileState< T, true >::AllocationSize ( int  num_tiles,
size_t &  temp_storage_bytes 
)
inlinestatic

Compute device memory needed for tile status

Parameters
[in]num_tilesNumber of tiles
[out]temp_storage_bytesSize in bytes of \t d_temp_storage allocation

Definition at line 193 of file single_pass_scan_operators.cuh.

◆ Init()

void *  d_temp_storage,
size_t   
)
inline

Initializer.

Parameters
[in]d_temp_storageDevice-accessible allocation of temporary storage. When NULL, the required allocation size is written to temp_storage_bytes and no work is done.

Definition at line 179 of file single_pass_scan_operators.cuh.

◆ SetInclusive()

template<typename T >
__device__ __forceinline__ void cub::ScanTileState< T, true >::SetInclusive ( int  tile_idx,
T  tile_inclusive 
)
inline

T  tile_partial 
)
inline

Update the specified tile's partial value and corresponding status

Definition at line 246 of file single_pass_scan_operators.cuh.
