Struct faiss::SIMDResultHandlerToFloat

struct SIMDResultHandlerToFloat : public faiss::SIMDResultHandler

Subclassed by faiss::simd_result_handlers::ResultHandlerCompare< C, false >, faiss::simd_result_handlers::ResultHandlerCompare< C, with_id_map >

Public Functions

inline SIMDResultHandlerToFloat(size_t nq, size_t ntotal)
inline virtual void begin(const float *norms)
inline virtual void end()
virtual void handle(size_t q, size_t b, simd16uint16 d0, simd16uint16 d1) = 0

called when 32 distances are computed and provided in two simd16uint16. (q, b) indicate which entry it is in the block.

virtual void set_block_origin(size_t i0, size_t j0) = 0

set the sub-matrix that is being computed
