- GPU monitor: 5s interval nvidia-smi sampling during benchmarks - A/B test script: clean restart + monitor + benchmark for Combined vs PD-Sep - Fixed proxy: await bootstrap init (race condition), normalized LB scoring - Fixed port conflicts: proxy 9090 to avoid bootstrap 9000 clash Key finding: PD-Sep GPU utilization is 40% of Combined (12.4% vs 30.5%) - Decode GPUs: mean=7.8%, max=47% (memory-bound, compute wasted) - Prefill GPUs: active only 17% of samples (bursty, idle between requests) - Combined: 8 GPUs flexibly used, mean=30.5%, active=64% Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
