# GLM-5.3-Flash on 4× DGX Spark — aiden image with the LAB's own DFlash2 # drafter (local-inference-lab/GLM-5.3-Flash-DFlash2, 1.2 GB, on the shared # NAS HF) instead of incoai's — the competitive A/B the user asked for: # same image, same NVFP4 checkpoint, only the speculative model differs. # (This recipe = glm53-flash-aiden-4x with the drafter swapped.) # # PARKED 2026-09-04: with the MXFP8→bf16 dequantized lab drafter the target # loads clean and the drafter loads (no missing params), but the FIRST draft # pass at warmup dies in _project_context_kv: "mat1 and mat2 same dtype — # BFloat16 vs Float8_e4m3fn" (the fused KV-proj weight ends up fp8 at # runtime — the NVFP4 target's quant config bleeds into the draft's linears, # and the lab drafter's layout doesn't survive that path; incoai's does). # The lab drafter belongs to the lab's own vllm fork (newer dflash + aux- # capture). Revisit with a lab-fork image build. # # aiden's production 4-node profile, verbatim translation of # https://aidenle.com/recipes/glm-5-3-flash-4x-dgx-spark into our 4x launcher # shape. Reference numbers (his, single stream, idle cluster, thinking off): # ~84 tok/s decode (FP8, DFlash2 k=7) — NVFP4 +23% (110.7 structured); # prefill ~2,100 cold; TTFT 4 s @ 8K → 40 s @ 94K; KV 2.25M tokens at 16 GiB # pin; 393K context verified. Decode flat with context (34/45 KDA layers + # 11 sparse-MLA @ index_topk 2048). # # DFlash2: acceptance 0.5–0.8; k=7 (drafter block 8 − 1 target token); k=6 # wins prose, loses structured. Native MTP fallback (production-1.0 image or # spec omitted) optimum k=5. ~15 min full relaunch on FP8 (963 s measured). # FP8-MLA + DFlash2 combination is STRUCTURALLY broken upstream (three trees # fail differently) — hence plain fp8_e4m3 KV. # # NOT READY TO DEPLOY: needs a 4-node cluster (ds4 + 2nodes-dac freed) and the # unsloth/GLM-5.3-Flash-FP8 checkpoint (328 GB — background download running # on dgx3, /tmp/dl_fp8.log; ~340 GB free per node required for weights + Triton # cache). Fabric: RoCE dual-HCA NCCL profile comes from the launcher (config # [nccl.*] / GID auto-detect) — his NCCL_* env block intentionally omitted. # NOTE: his launcher unsets VLLM_PREFIX_CACHE_RETENTION_INTERVAL via bash -lc # before exec; if our boot rejects it in the KV coordinator, add a mods script. engine = "vllm" name = "GLM-5.3-Flash aiden image (vLLM, 4x Spark, LAB DFlash2-7, NVFP4)" docker_image = "sparkrun-vllm-glm53-flash-aiden:glm53" docker_image_dir = "glm53-flash-aiden" model = "local-inference-lab/GLM-5.3-Flash-NVFP4" parent_model = "zai-org/GLM-5.3-Flash" required_nodes = 4 tensor_parallel_size = 4 pipeline_parallel_size = 1 distributed_backend = "mp" shm_size = "32gb" # image ships ENTRYPOINT ["vllm","serve"]; our launcher passes the recipe # entrypoint as CMD words after the image, which would double it.
