numa aware scheduling

**NUMA-Aware Scheduling** is the **placement strategy that aligns threads and memory to socket locality on multisocket servers**. **What It Covers** - **Core concept**: reduces remote memory latency and cross socket traffic. - **Engineering focus**: improves bandwidth stability for data intensive jobs. - **Operational impact**: supports predictable performance on shared servers. - **Primary risk**: static pinning can hurt balance under shifting load. **Implementation Checklist** - Define measurable targets for performance, yield, reliability, and cost before integration. - Instrument the flow with inline metrology or runtime telemetry so drift is detected early. - Use split lots or controlled experiments to validate process windows before volume deployment. - Feed learning back into design rules, runbooks, and qualification criteria. **Common Tradeoffs** | Priority | Upside | Cost | |--------|--------|------| | Performance | Higher throughput or lower latency | More integration complexity | | Yield | Better defect tolerance and stability | Extra margin or additional cycle time | | Cost | Lower total ownership cost at scale | Slower peak optimization in early phases | NUMA-Aware Scheduling is **a practical lever for predictable scaling** because teams can convert this topic into clear controls, signoff gates, and production KPIs.
