- Fastest verified SGLang setup for Qwen3.8-27B W4A16 AutoRound on 2x RTX 3090 with TP2. Uses DFlash speculative decoding with a local W8A16 DFlash2 drafter, 6 draft tokens, and a 40,960-token output-derived curated candidate vocabulary distributed across TP ranks. Candidate selection uses rank-local projection/top-k with compact cross-rank communication. Target execution uses torch.compile, CUDA graphs, selective SM86 W4A8 Marlin MLP kernels, BF16 KV/recurrent state, compiler-safe DFlash causal-convolution verification, and persisted tuned TorchInductor/Triton caches. Measurement is concurrency 1 with 2 warmups and 5 timed 512-token iterations. CUDA peer access and NVLink are unavailable on this PCIe topology, so TP collectives use NCCL's host-mediated path.
