Canonical title: INF²: High-Throughput Generative Inference of Large Language Models using Near-Storage Processing | |||
Question: Can long-context LLM attention scale beyond host memory bandwidth by processing KV cache near SSDs? | |||
Context: Offloaded inference repeatedly transfers large KV state across the host-storage link. | |||
Method: INF² executes attention near computational storage, delays KV writeback, and coordinates a host-side X-cache in a PyTorch prototype. | |||
Evaluation: workloads=30B, 66B, and 175B LLMs at long context lengths; baselines=state-of-the-art offload systems including FlexGen; metrics=generative-inference performance; results=up to 3.46x speedup | |||
Interpretation: Moving attention to stored KV state can replace bandwidth-heavy data movement with near-data compute. | |||
Reusable lesson: Offload the operator whose input is largest and most stationary, then cache only its high-value working set centrally. | |||
Applicability: Long-context LLM inference with computational-storage devices. | |||
Limits: Requires near-storage compute and custom software; arXiv publication status only was verified.</nowiki> | |||
