v1.8.0

943d08b

V1.8.0

Added

Added a new conda package faiss-gpu-raft alongside faiss-cpu and faiss-gpu
Integrated IVF-Flat and IVF-PQ implementations in faiss-gpu-raft from RAFT by Nvidia [thanks @cjnolet and @tarang-jain]
Added a context parameter to InvertedLists and InvertedListsIterator
Added Faiss on Rocksdb demo to showing how inverted lists can be persisted in a key-value store
Introduced Offline IVF framework powered by Faiss big batch search
Added SIMD NEON Optimization for QT_FP16 in Scalar Quantizer. [thanks @naveentatikonda]
Generalized ResultHandler and supported range search for HNSW and FastScan
Introduced avx512 optimization mode and FAISS_OPT_LEVEL env variable [thanks @alexanderguzhva]
Added search parameters for IndexRefine::search() and IndexRefineFlat::search()
Supported large two-level clustering
Added support for Python 3.11 and 3.12
Added support for CUDA 12

Changed

Used the benchmark to find Pareto optimal indices. Intentionally limited to IVF(Flat|HNSW),PQ|SQ indices
Splitted off RQ encoding steps to another file
Supported better NaN handling
HNSW speedup + Distance 4 points [thanks @alexanderguzhva]

Fixed

Fixed DeviceVector reallocations in Faiss GPU
Used efSearch from params if provided in HNSW search
Fixed warp synchronous behavior in Faiss GPU CUDA 12

v1.7.4

d87888b

v1.7.4

Added

Added big batch IVF search for conducting efficient search with big batches of queries
Checkpointing in big batch search support
Precomputed centroids support
Support for iterable inverted lists for eg. key value stores
64-bit indexing arithmetic support in FAISS GPU
IndexIVFShards now handle IVF indexes with a common quantizer
Jaccard distance support
CodePacker for non-contiguous code layouts
Approximate evaluation of top-k distances for ResidualQuantizer and IndexBinaryFlat
Added support for 12-bit PQ / IVFPQ fine quantizer decoders for standalone vector codecs (faiss/cppcontrib)
Conda packages for osx-arm64 (Apple M1) and linux-aarch64 (ARM64) architectures
Support for Python 3.10

Removed

CUDA 10 is no longer supported in precompiled packages
Removed Python 3.7 support for precompiled packages
Removed constraint for using fine quantizer with no greater than 8 bits for IVFPQ, for example, now it is possible to use IVF256,PQ10x12 for a CPU index

Changed

Various performance optimizations for PQ / IVFPQ for AVX2 and ARM for training (fused distance+nearest kernel), search (faster kernels for distance_to_code() and scan_list_*()) and vector encoding
A magnitude faster CPU code for LSQ/PLSQ training and vector encoding (reworked code)
Performance improvements for Hamming Code computations for AVX2 and ARM (reworked code)
Improved auto-vectorization support for IP and L2 distance computations (better handling of pragmas)
Improved ResidualQuantizer vector encoding (pooling memory allocations, avoid r/w to a temporary buffer)

Fixed

HSNW bug fixed which improves the recall rate! Special thanks to zh Wang @hhy3 for this.
Faiss GPU IVF large query batch fix
Faiss + Torch fixes, re-enable k = 2048
Fix the number of distance computations to match max_codes parameter
Fix decoding of large fast_scan blocks

v1.7.3

19f7696

v1.7.3

Added

Sparse k-means routines and moved the generic kmeans to contrib
FlatDistanceComputer for all FlatCodes indexes
Support for fast accumulation of 4-bit LSQ and RQ
Product additive quantization support
Support per-query search parameters for many indexes + filtering by ids
write_VectorTransform and read_vectorTransform were added to the public API (by @AbdelrahmanElmeniawy)
