# GLM-5.3-Flash NVFP4 (lab quant) on the COMMUNITY sparkrun image — 2× DGX # Spark, TP=2. # # Image: aidendle94/sparkrun-vllm-glm53-gb10 (Spark Arena / sparkrun # orchestrator's GLM-5.3 vLLM build). Verified 2026-08-29: same day-0 vLLM # dev base as our lab image reports (v0.1.dev20051+g487ecf187, torch # 2.13.0+cu130), arm64-only (no manifest list — sm_121 target), generic # `vllm serve` entrypoint, no baked weights. Digest pin (single-arch # manifest, checked with `docker manifest inspect`): # sha256:9b0592293a0b0161a040568578aca330227a03d140fa1c5f8965f64292431ef0 # # WHY THIS RECIPE: cross-checks our home-built lab image against the Spark # Arena community stack — same checkpoint, same proven flag set, different # runtime. If both boot and score alike, the flag set (not our patches) is # the load-bearing part; any delta localizes to the image overlay. # Flags are mirrored verbatim from recipes/glm53-flash-nvfp4-lab (their # launch config + our fabric/env deviations — see that header for the full # rationale of each knob). # # Weights live on the NAS (mounted at /mnt/nas on the nodes) and are # exposed to the container via extra_mounts + HF_HOME — no per-node # `hf download` needed (config.toml [mount_aliases] hf_cache repoints this # site-wide). # # Boot markers: "Model loading took ~92.7 GiB" → "[quantprobe] … # algo=MXFP8" (MTP/modelopt fix active in this image; algo=None means the # image lacks the mod — report and fall back to our lab image) → # "GPU KV cache size" → "Application startup complete". # # Chat needs "chat_template_kwargs":{"reasoning_effort":"low"} — omitted or # other values select MAX reasoning effort (empty content on short # max_tokens). engine = "vllm" name = "GLM-5.3-Flash W4A16-AutoRound Intel (vLLM, 2x Spark, r12 fork)" # glm53-jovian-r12:local — our in-docker build of local-inference-lab/vllm # (jovian-judgement composition + PR heads 550-557) with the native # Glm5NextForConditionalGeneration arch and B12X sparse-MLA attention. # The timothystewart6 image was abandoned: upstream vLLM 0.28 there has NO # native glm5_next arch (its Transformers-backend fallback lacks the # per-stream q_conv1d weight mapping — boot dies in the weight loader). docker_image = "glm53-jovian-r12:local" docker_image_dir = "glm53-jovian-r12" model = "Intel/GLM-5.3-Flash-W4A16-AutoRound" parent_model = "zai-org/GLM-5.3-Flash" required_nodes = 2 tensor_parallel_size = 2 pipeline_parallel_size = 1 distributed_backend = "mp" shm_size = "32gb" args = [ # Stable served name — quant-agnostic (shared across glm53 quants) "--served-model-name", "glm53", "--trust-remote-code", # AutoRound int4 pack → GPTQ-style safetensors; explicit quant route (the # timothystewart6 upstream-stack build knows quant_method auto-round).
