◆ AllocationSize()

template<typename T >
__host__ __device__ static __forceinline__ cudaError_t cub::ScanTileState< T, false >::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 348 of file single_pass_scan_operators.cuh.

◆ Init()

size_t  temp_storage_bytes 
)
inline

Initializer.

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