Building Low‑Latency RPC Systems for Orchestrating Distributed Small Language Model Clusters
Table of Contents Introduction Why Latency Matters for Small LLM Clusters Core Requirements for an RPC Layer in This Context Choosing the Right Transport Protocol Designing an Efficient Wire Protocol Connection Management & Load Balancing Fault Tolerance, Retries, and Back‑Pressure Practical Example: A Minimal RPC Engine in Go Performance Benchmarking & Tuning Security Considerations Deployment Patterns (Kubernetes & Service Meshes) Real‑World Case Studies Best‑Practice Checklist Conclusion Resources Introduction The rapid rise of small, fine‑tuned language models (often called “tiny LLMs” or “micro‑LLMs”) has opened the door to edge‑centric AI and high‑throughput inference pipelines. Unlike massive foundation models that require a single, powerful GPU, these lightweight models can be sharded across dozens or hundreds of commodity nodes, each serving a few hundred queries per second. ...
