Swept ncmoe(30..40) x ubatch(256..4096) on the RTX 3090 (Qwen3.6-35B-A3B Q6_K_P, pp16384/tg512, fit-target 0). Key findings: - Generation depends only on ncmoe: 40.9 (ncmoe40) .. 51.1 (ncmoe30); ubatch/batch do not affect decode at all. - Prefill + graph VRAM scale with ubatch; logical batch is irrelevant. - VRAM model (peak + 11.44GiB KV pool + 2.2GiB overhead) reproduces the historical OOMs: ncmoe32-ub2048 sums ~24.4GiB > 24. Chosen state: ncmoe 32 (8 expert layers on GPU), batch 8192, ubatch 1024. gen ~48.7 t/s (+7% vs prior ncmoe 35), prefill ~766 t/s, ~1.0GiB headroom. Alternates: ncmoe34-ub2048 (gen 46.4, pp 1221, 1.5GiB) for prefill-heavy; ncmoe32-ub768 (1.3GiB) if headroom matters most. Docs: new frank-default-small-benchmark.md; synced deployment.md + specs.
