# frank-primary.env — tcclaviger RDNA4 vLLM production config (dankserver :7770). # # 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 262144 x SEQS 3 (786,432 tokens) at bf16 KV boots at # KV_BYTES 11,047,010,304 PER RANK: the engine measured "KV cache size: # 798,280 tokens; Maximum concurrency for 262,144 tokens per request: # 3.05x". The pool holds all three full windows with an 11,848-token # margin. Measured decode at the winner shape: 39.38/38.79/36.42 tok/s # (166/1087/4064 ctx). # * 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. # # --- runtime ---------------------------------------------------------------- # Digest-pinned: the floating :latest tag moved once already.
