# DeepSeek-V4.1-Flash EXL3 3bpw — coolbho3k "2x DGX Spark" production recipe, # adapted to sm121 (rc2 image, pinned at release commit 878e0ee). # # 2x Spark over 200G RoCE (8nodes-switch, first two free ranks): # TP2/DCP2, DSpark K=3 drafter, EXL3 3bpw experts, FP4 main KV + FP8 SWA, # 1M context, GMU 0.92, max-num-seqs 2 (C2; the runtime's cooperative # profile validates 1..6), prefill batch 3072. # # 2 GB headless-RAM unlock: the runtime's display-pool KV (1.75 GiB of the # firmware's 2 GB display reserve per GPU) needs nvidia_drm remoded with # modeset=1 fbdev=0. That is TEMPORARY by design (technology still in # approval): before_serve remods per boot, after_stop restores the plain # module. No UEFI change, no /etc/modprobe.d entry, resets on reboot. # # Model + drafter overlay live on the shared NAS (hub layout); the launch # nodes symlink the current refs/main snapshot and bind it at /model (the # runtime hard-requires the model at exactly /model) and the drafter overlay # at /draft-exl3. # # Cgroup: the runtime's serving guard hard-requires a 9 GiB / no-swap / # <=6-CPU cgroup (memory.max==9g, swap 0, cpu quota <=6) — memory_limit + # cpus below. engine = "vllm" docker_image = "ghcr.io/coolbho3k/deepseek-v4.1-flash-exl3-3bpw-2x-dgx-spark:20260917-rc2" model = "" name = "DeepSeek-V4.1-Flash EXL3 3bpw (2x Spark, TP2/DCP2, DSpark K=3, 1M)" port = 8888 required_nodes = 2 cluster = "8nodes-switch" tensor_parallel_size = 2 distributed_backend = "mp" shm_size = "2g" devices = ["/dev/dri/card0"] memory_limit = "9g" cpus = 6 # /model + /draft-exl3 are the exact mounts the runtime validates. entrypoint = [ "/opt/ds41-venv/bin/python", "/opt/ds41-serving/serve.py", "serve", "/model", "--config", "/opt/ds41-serving/conservative.yaml", "--worker-cls", "combined_worker.CombinedWorker", "--disable-custom-all-reduce", ] args = [ "--served-model-name", "deepseek-v41-flash-exl3", "--enable-auto-tool-choice", "--tool-call-parser", "deepseek_v41", "--reasoning-parser", "deepseek_v41", ] before_serve = [ { script = "unlock_display_ram" }, # Stable per-node symlinks to the current refs/main snapshots (recreated # every serve; docker resolves the symlink at bind time).
