# GLM-5.3-Flash on 2× DGX Spark — aidendle94 sparkrun image (TP=2).
#
# aiden's 4x guide (https://aidenle.com/recipes/glm-5-3-flash-4x-dgx-spark)
# translated to our 2-node ds4 launcher: same image (production-1.2 — SM90
# NoPE-MLA-to-capability-12 route + three functional fixes + DFlash2 overlay),
# same serve flags, TP2 instead of TP4.
#
# Image: aidendle94/sparkrun-vllm-glm53-gb10:production-1.2 (Docker Hub).
#   production-1.0 = MTP-only fallback; 1.1 ships the DFlash2 drafter overlay
#   (drafter package + aux-capture patch + KV-page LCM patch + backend-registry
#   patch); 1.2 adds a fused Triton mHC prefill kernel (post-mix + pre-norm
#   GEMM + sinkhorn pre-mix + RMSNorm in one pass; aiden: 1.37x on the mHC
#   section at 4K tokens, prefill ≥1024 tokens, hc_mult=4). Same wheel and
#   overlays otherwise. VLLM_MHC_FUSED_LARGE=0 reverts to the 1.1 path.
#   Grep the log for "B12X PCIe|DFlash" style markers per his guide.
#
# Weights: LibertAIDAI/GLM-5.3-Flash-NVFP4 (194 GB, 97 GiB/node at TP2; cached
# on both nodes). aiden: NVFP4 is ~23% faster than unsloth FP8 (which needs 4
# nodes at 82 GB/rank). Drafter: incoai/GLM-5.3-Flash-DFlash2 (2.34 GB, cached).
#   spec k MUST be 7 = block_size(2304? no: drafter block 8) − 1; acceptance
#   0.5–0.8, ~0.15 = broken aux capture (silent).
#
# Memory plan (2x): 97 GiB weights/node + KV pin 4 GiB + eager activations
# ≈ 103 GiB vs GMU 0.85 × 121.63 = 103.4 GiB. If a boot dies on free-memory,
# drop KV pin to 3 GiB or GMU to 0.83. KV pool ≈ 400-600K tokens — fine for
# agent-class benches, NOT for the 393K context the 4x profile serves.
#
# WARNING (from aiden's guide, untested on our 2x boot): the image bakes
# VLLM_PREFIX_CACHE_RETENTION_INTERVAL; his launcher unsets it via bash -lc.
# If the boot rejects the value in the KV coordinator, add a mods script that
# unsets it (ours cannot env-unset across the exec boundary).
#
# Boot markers: "Loading safetensors" (~2-4 min sequential from NVMe) →
# "GPU KV cache size" → "Application startup complete". DFlash2 acceptance
# 0.5-0.8 in SpecDecoding metrics.
