# DeepSeek-V4.1-Flash — local-inference-lab r37 (jovian-judgement, 2026-09-13), 4x.
#
# Clone of dsv41-flash-jovian-r36-4x retargeted at the r37 source lock — the
# lab's newest published DS4.1 qualification. r37's headline is a
# kernel-dispatch overhead removal: no more repeated CPU argument-list
# expansion, mutable-schema inspection, scalar dtype allocations or
# tensor-equality calls per dispatch (no quantization or sampling change);
# plus measured B12X projection tiles, four FP32 projection partials, visible
# index-score tiles, a compact mHC prefill config, removed attention-output
# copies and bounded short-index scratch. Their RTX-quartet qualification
# (public-source control -> r37): uncached 32K prefill 14,896 -> 21,399 tok/s
# (+43.65%), C1 output 238.80 -> 281.08 tok/s (+17.70%, budget-50 three-cell
# median), C1 verifier +11.92%, Sieve +8.17%. r37 also corrects the named
# `high` reasoning budget 50 -> 75 (behaviour, not speed — our benches pass
# reasoning_effort explicitly). Carries the B12X small-tile barrier fix (#363)
# and TP3 prefill-head support (TP3 is not serving-qualified here).
#
# Image: our own build for GB10 sm_121a from docker-images/glm53-jovian-r27
# with profile jovian-r37-ds41 (vLLM c687594b8a8 + b12x f1c4e9dd5b1; LMCache
# 29bc5a2e / FlashKDA 3b225bf2 / DeepGEMM 8b1392b9 unchanged; torch 2.13.0 +
# flashinfer 0.6.17 = the same GB10 pins as r35/r36, dep gates re-checked
# against the r37 tree; liburing 2.5 + dev headers already in the apt lock).
# The published lab image is CUDA 13.3 x86 / sm_120 — ours is the documented
# CUDA 13.2 aarch64 / sm_121a deviation.
#
# Serving profile, GB10 deviations and the Engram-on-node-NVMe mechanism are
# unchanged from r36 (see that recipe's header + history/night-shifts/
# 2026-09-12.md "Day follow-up 2/3"): TP4/DCP1, native DSpark K7 (greedy
# draft, standard rejection, adaptive verification), 512K (our floor — their
# 131K qualified profile is not usable for us), GMU 0.88, B12X attn/MoE/linear,
# block 256, instanttensor, Engram table on disk via
# [composed_model].local_files hardlinked from the eugr lane's per-rank sparse
# copies in /var/tmp/engram-local (48 GB real per node, zero extra disk).
#
# Measured reference points (dev65/seed 42, d0 c1):
#   r36 + local Engram @512K   154/176 (88), 3,774 pp / 45.7 tg /  822 ms TTFT
#   r36 + local Engram @131K   149/176 (85), 3,654 pp / 43.9 tg /  826 ms
#   r36 + Engram over NFS      158/176 (90),   401 pp / 33.7 tg / 5,061 ms
#   eugr dsv41 prod (K5)       167/176 (95), 1,642 pp / 47.0 tg / 1,738 ms
# What r37 targets: the same r36 profile with their +43% prefill fix. The A/B
# vs the eugr prod decides (quality gap vs speed lead) — plan:
# history/night-shifts/2026-09-13.md.
#
# PREREQUISITE: weights in the shared NAS HF cache; per-node local Engram
# sparse copies under /var/tmp/engram-local/DeepSeek-V4.1-Flash.
