Local cluster setups can outperform ad-hoc single-node deployments only when network and queue behavior are measured, not assumed.
Validate these metrics first
- Node-to-node latency
- TTFT jitter across nodes
- Throughput variance over sustained runs
Topology recommendation
- One primary GPU node
- One or two helper nodes for routing and orchestration
- Deterministic benchmark prompts across all nodes
Common mistakes
- Scaling nodes before validating a single node baseline
- Comparing results with different prompt lengths
- Ignoring thermal drift on the primary GPU node
Treat cluster readiness as a testable state, not an architecture diagram.
