Struct faiss::simd_result_handlers::SIMDResultHandler

template<class C, bool with_id_map>
struct SIMDResultHandler

Record origin of current block

Public Types

using TI = typename C::TI

Public Functions

inline explicit SIMDResultHandler(size_t ntotal)
inline void set_block_origin(size_t i0, size_t j0)
inline void adjust_with_origin(size_t &q, simd16uint16 &d0, simd16uint16 &d1)
inline int64_t adjust_id(size_t b, size_t j)
inline uint32_t get_lt_mask(uint16_t thr, size_t b, simd16uint16 d0, simd16uint16 d1)

return binary mask of elements below thr in (d0, d1) inverse_test returns elements above
