RVANNS: Mixed-Precision Indexing and Locality-Aware Graph Traversal on RISC-V
RVANNS is presented, an RVV-oriented ANNS engine that jointly optimizes vector representation and graph locality and achieves 3.39x and 4.94x speedups over scalar execution on real 128-bit and 256-bit RVV processors, respectively.
