NVIDIA has created accelerated vector search algorithms for IVF-Flat, IVF-PQ, and CAGRA (a new graph based algorithm specifically designed for GPU's). These algorithms are part of RAPIDS RAFT. RAFT contains fundamental widely-used algorithms and primitives for machine learning and information retrieval. The algorithms are CUDA-accelerated and form building blocks for more easily writing high performance applications. API's exist for Python and C++ (we do not currently have a Java API).
RAFT has been integrated into Milvus, Redis, and Faiss. We are looking for other integration partners. I wanted to see if there was an interest in the Lucene community. https://github.com/rapidsai/raft Nathan Nathan Stephens (He/Him/His) Enterprise Products: Data Science, AI/ML NVIDIA<http://www.nvidia.com/>
