KV-psi, a method using Linux PSI (Pressure Stall Information) to trim an LLM KV cache.

Technical Positioning
A technique to optimize LLM runtime memory usage, particularly for edge devices with unified memory like the Jetson Orin super nano kit.
SaaS Insight & Market Implications
This addresses a critical performance and resource management challenge for deploying Large Language Models (LLMs) on constrained hardware, specifically edge devices. The pain point is inefficient memory utilization, particularly the KV cache, which impacts LLM inference speed and feasibility on devices with unified memory. Leveraging Linux PSI for dynamic cache trimming represents an innovative approach to optimize resource allocation. This solution targets a growing market segment focused on local and edge AI deployments, where hardware efficiency is paramount. The implication is improved LLM performance and broader applicability on lower-cost, lower-power hardware, accelerating the trend of decentralized AI inference. Benchmarking will be crucial for market validation.

Show HN: KV-psi, using Linux PSI to to trim an LLM KV cache

I thought it'd be interesting to use Linux PSI (Pressure Stall Information) for an LLM runtime to trim the KV cache. This is mainly useful imo for edge devices like the Jetson Orin super nano kit which have unified memory. I haven't benched much, but plan to do so more over time and see if I can make a real use of it as I run local LLMs. Let me know if it makes sense :P (I of course vibed this idea)
