# GLM-5.3-Flash NVFP4-lab RE-CUT on r39 (jovian-judgement tip 2026-09-21),
# 2× DGX Spark, TP=2 — the E-track test lane.
#
# Purpose: does the lab's new tip (vLLM 9e5d1793fa3 + b12x c2dc1cf022)
# fix the r38 b12x preparation-pool deadlock (BUG-2026-09-19) on 2x GB10,
# and what does the RoCE traffic-class commit ("switched Spark fabrics")
# change? Same model/config as the proven re-cut 2x lane (r35, 91/100 @512K)
# — only the engine image moves (r35-glm53 -> r39-glm53, dir
# jovian-judgement-r39, profile r39). Everything else identical so the
# bench is a clean engine A/B.
#
# Note: r39 moved the external-dep contract (all cmake pins + DeepSelect),
# so the image builds from docker-images/jovian-judgement-r39 (its own
# fetch-deps.sh + deps.lock); the r27/r35 dir keeps the r38-era contract.
#
# Structure (verified from model.safetensors.index.json, identical to the
# Spark checkpoint): `model.language_model.layers.*` with SPLIT GDN naming
# (q/k/g_a/g_b/f_a/f_b/b_proj + hc_* hybrid-conv), a `model.visual.*`
# tower (skipped via --language-model-only), and the MTP head embedded at
# layer 45 (eh_proj/enorm/hnorm) — no separate drafter download. Same
# loader path as the Spark lane: the JJ fork lineage (r35) maps it natively
# (no KeyError); r38 is out — b12x preparation-pool deadlock on 2x GB10.
#
# Image: jovian-judgement:r35-glm53 + VLLM_DISABLED_KERNELS (the small GDN
# mxfp8 GEMMs reject flashinfer cutlass' min n/k=128 — routed to the b12x
# Mxfp8 backend; proven on the Spark lanes 162/176 + 161/176).
#
# Memory: 199.4 GB / 2 ranks ≈ 93 GiB weights/node at GMU 0.88 (107.0 GiB)
# — no KV pin (auto-sizing takes the remaining ~10 GiB; a 10 GiB pin as in
# the old 186 GB cut would overshoot the tighter budget).
#
# PREREQUISITES: weights on each node's LOCAL hub (the NAS disk died
# 2026-09-19): /home/kilork/hf-local, ~/.cache/huggingface symlink
# re-pointed per node. Re-cut re-download in progress on all 4 nodes
# (dgx1 is the tightest: ~40 GiB left after the model).
