HELMSMAN: Redefining Large-Scale Vector Retrieval on All‑Flash Servers (OSDI 2026)
HELMSMAN replaces DRAM‑heavy graph indexes with a clustering‑based, SSD‑first ANN system that uses a custom SPDK storage stack, adaptive LLSP pruning, and a GPU‑CPU construction pipeline, achieving 2‑16× throughput, up to 85% of in‑memory performance, and over 90% hardware cost reduction for billion‑scale search workloads.
