# DeepSeek-V4-Flash-Vision-Exp on 4× GB10 — aiden production profile. PARKED. # # 2026-09-03: parked — this image's FP8 O-proj einsum path (B12X/FlashMLA/ # FlashInfer sparse attention shared kernel, DeepGEMM fp8_einsum) hard-asserts # "layout.hpp:39: t.dim() == N" at warmup on our GB10s in EVERY config tried # (2x TP2 GMU 0.85 no-pin; 4x TP4+DCP2 — his exact production shape). It is a # kernel/JIT layout issue in the image on our hardware, not a flag difference. # Vision lanes stay on our proven dsv4-flash-vision overlay image (2x: 88/100). # # Source: https://aidenle.com/recipes/deepseek-v4-flash-vision-4x-dgx-spark/ # TP4 across 4 nodes with **DCP2 inside it** and DSpark-6 running together — # the combination stock vLLM refuses twice ("DSpark requires DCP_SIZE=1" + # "Non-causal DSpark SWA does not support DCP"); aiden's image resolves it by # marking the draft's sliding-window cache `dcp_replicated` (full ctx on every # rank, cost-free for a few hundred tokens). Shipped profile numbers: # decode 66-71 tok/s @ acceptance 3.5-3.8; cold 334K prefill 2,088 tok/s; # KV pool 3.51M tokens (8.9× full-length ctx); 393K ctx verified; # image request ~1.2 s warm / ~6 s first. # # Profile trade (his table): DSpark+DCP1 73.8-75.2 / DCP2-no-spec 34 / # DSpark+DCP2 66-71 (DCP1 pool 1.77M vs DCP2 3.51M — KV doubled at ~7% decode). # # NOT READY TO DEPLOY: needs a 4-node cluster window. Fabric NCCL envs omitted # here (launcher-managed, [nccl.*]). His runner envs carrying operational # requirements: earlyoom tuned on every node, root for RDMA passthrough + # memlock + page-cache flushing, ~120 GB free per node for weights + JIT cache. # # Env/flag deltas vs our 2x variant (dsv4-vision-aiden-2x): DCP_SIZE=2, # --decode-context-parallel-size 2 --dcp-comm-backend ag_rs (ag_rs = +12% KV # over a2a), KV_CACHE_MEMORY_BYTES unpin (empty — the ~26 GB cap off), # GPU_MEMORY_UTILIZATION 0.75 (0.82 → earlyoom kills a worker on his kit), # VLLM_DSV4_CKV_GATHER=1 + CKV_GATHER_MAX_TOKENS + ALLOW_IMAGES (prefill # gather required for images under DCP). engine = "vllm" name = "DeepSeek V4 Flash Vision-Exp (aiden image, 4x Spark, DSpark-6 + DCP2) [DEFERRED]" docker_image = "aidendle94/sparkrun-vllm-ds4-gb10:production-3.72-vision" model = "deepseek-ai/DeepSeek-V4-Flash-Vision-Exp" required_nodes = 4 tensor_parallel_size = 4 pipeline_parallel_size = 1 distributed_backend = "mp" shm_size = "32gb" # the image's BAKED-IN entrypoint is aiden's env-script (doubles our tail # args if left in place).
