Night ladder result (Frank's subtract-16k method): 262144 and 245760 both OOM
at CUDA graph capture ('Tried to allocate 76.00 MiB ... 0 bytes free'), 237568
passed (KV 718,606 tokens), and the +4096 bonus step PASSED -> 241664 is max
possible and DEPLOYED at util 0.98 (KV 732,359 tokens / 3.03x concurrency at
241,664-token requests). Util stays 0.98: lowering it shrinks the engine's own
budget instead of buying slack.
Client contract restored (the GLM rollback d91379d dropped all three and the
qwen rollback inherited the gap): --reasoning-parser qwen3 fixes the malformed
thinking block (thinking was landing inline in content with a dangling
</think> and a null reasoning field), --enable-auto-tool-choice with
--tool-call-parser qwen3_xml makes tools work, and
--default-chat-template-kwargs enables enable_thinking + preserve_thinking.
Harness: contextWindow 241664 (compaction gap recomputed), preserve_thinking
moved into chat_template_kwargs.

|
|
# 2026-10-01 cutover to the BF16-KV no-spec incumbent (the overnight redo
|
|
# campaign's verdict, Frank's call): same digest-pinned engine and payload as
|
|
# the 2026-09-29 cutover, but the KV cache is UNQUANTIZED (auto = bf16) and
|
|
# speculative decode is GONE. Git tag frank-primary-fp8-mtp-20261001 is the
|
|
# last pre-cutover commit; the old shape (fp8 KV + MTP4) is in history and
|
|
# restorable from the tag.
|
|
#
|
|
# Every number here was QUALIFIED by boot probe on 2026-10-01 (not inherited):
|
|
# * MAXLEN 241664 x SEQS 3 (724,992 tokens) at bf16 KV is the DEPLOYED
|
|
# shape (2026-10-01 night ladder): KV_BYTES 10,184,000,000 PER RANK,
|
|
# engine measured "KV cache size: 732,359 tokens; Maximum concurrency
|
|
# for 241,664 tokens per request: 3.03x". 262144 and 245760 both OOMed
|
|
# at graph capture (76 MiB short / 0 bytes free); 237568 passed at
|
|
# 718,606 tokens and the +4096 bonus step passed and won.
|
|
# * KV_BYTES is PER RANK. The old "7.2 GiB ceiling, 9/16 GiB OOM" law was
|
|
# the MTP4 WORKSPACE: the spec-era pool measured 729,545 tokens because
|
|
# the drafter reserved ~2.6 GiB/rank beside the pool. No-spec bf16 takes
|
|
# 11.05 GiB/rank and boots clean — the ceiling was spec's, not VRAM's.
|
|
# * bf16 KV doubles the attention-KV bytes/token (measured 14,047 vs
|
|
# 7,926) and costs ~14% decode vs fp8 at 4064 ctx (49.25 -> 36.42 with
|
|
# the gather win) — traded deliberately for clean cache + 262k windows.
|
|
# * GATHER 32x64 is the night's biggest lever: R4D_LRU_GATHER_CHUNKS=32 /
|
|
# R4D_LRU_GATHER_LANES=64 measured +18.7% decode vs default geometry,
|
|
# and the win grows with depth (39.5@166 -> 54.1@1087 -> 49.3@4064 fp8
|
|
# era). Do not drop it.
|
|
# * MNBT 1024 is Frank's lock: MNBT 512 doubles TTFT at 4064 ctx (2.46 s
|
|
# vs 1.36 s); 1024-4096 are interchangeable on decode; 12288 costs 2.5%
|
|
# and arena. 1024 keeps the workspace floor so the arena stays max.
|
|
# * PREFETCH IS ABSENT BY LAW: expert-cache telemetry measured the
|
|
# prefetcher at 36% precision (36,720 slabs prefetched, 13,369 served) —
|
|
# roughly half the gather traffic was waste. Never re-add
|
|
# --expert-prefetch without a fresh A/B.
|
|
# * TunableOp stays OFF: CLAV_TUNABLEOP_SWEEP silently skips under expert
|
|
# offload unless CLAV_TUNABLEOP_WITH_OFFLOAD=1, and forcing it corrupts
|
|
# numerics.
|
|
#
|
|
# HIP reads bare env vars TEMP, HOST, GPU_MAX_HEAP_SIZE — every key here is
|
|
# prefixed FRANK_PRIMARY_ so none can leak.
