Qwen3-235B on Firmus AI Cloud (2× HGX H200) — PD serving reproduction guide
APAC HPC-AI Challenge 2026. Serving Qwen3-235B-A22B-Instruct-2507-FP8 with
SGLang prefill/decode disaggregation on the Firmus AI Cloud cluster — two HGX
H200 nodes (16 GPUs, 8× InfiniBand NDR), 17-minute walltime per job. Every number in this folder is read out of
results/logs/profile_export_aiperf.json from a real full-protocol run.
Current result (job 22002, "bor10d"): goodput 24.20 req/s = 4,840 good output tokens/s at declared N=108, good_request_fraction 0.9648.
(Fractions in this guide are the scored-window values — the export's
top-level good_request_fraction. Warmup-phase values are noted separately.)
The metric
score = goodput (req/s) x OSL (200) = good output tokens/s
A request counts as good only if it satisfies every SLO:
| gate | limit |
|---|---|
| TTFT | <= 3000 ms |
| ITL (per-request average) | <= 20 ms |
good_request_fraction |
>= 0.90 (below this the run scores zero) |
ISL 4000, OSL 200, closed-loop at the declared concurrency N, official AIPerf
command verbatim (warmup 60 / benchmark 120 / grace 30, seed 2026,
--cache-bust first_turn_prefix, greedy).
Result — official protocol, job 22002 (bor10d, argmax-gather patch)
| metric | value |
|---|---|
| goodput | 24.20 req/s -> 4,840 good tok/s |
| good_request_fraction (scored) | 0.9648 (2,984 of 3,093 requests; 0 errors) |
| request throughput | 25.08 req/s |
| TTFT avg / p50 / p99 | 734.0 / 587.8 / 3,539.8 ms |
| ITL avg / p50 / p99 | 17.68 / 17.76 / 20.27 ms |
| output token throughput | 5,016 tok/s |
| input token throughput | 99,978 tok/s |
| N declared | 108 |
Failures: 109 misses in the scored window (3.5%), zero request errors — both
tails improved vs the prior best (TTFT p99 3,654.6 -> 3,539.8 ms; ITL p99
20.60 -> 20.27 ms). The final lever is the argmax-gather patch
(build/patches/03 + 04): the per-step full-vocab logits gather and the
degenerate-penalty pass on the EAGLE3 greedy verify path are replaced by a
packed candidate gather (per-rank top-4 + one small packed all-gather;
penalties applied to candidates only, assert-guarded). Lossless under the
official command: greedy-only gate, penalties asserted to be {0, -inf},
accept held at 2.00. Measured: goodput 23.49 -> 24.20 req/s at the same N
(4,697.8 -> 4,839.7).
History at this N: spec-mode decode 4,681.5 (job 21544) / 4,697.8 (job 21698); the N-sweep closed at N=108 (N=116 invalid — frac 0.8618).
Artifacts: results/logs/ carries the job-22002 export; the 21544 and 21698
samples are results/confirmation-*-profile_export_aiperf.json; the verbatim
scored scripts are run/champion-22002.sbatch (best) and
run/champion-21698.sbatch (prior best).
Two run_meta.json fields are harness-template defaults, not the run's actual
env: mem_frac records 0.9 (the prefill value) and rail_affinity records
true; the authoritative per-worker values are the export lines in
run/champion-22002.sbatch — MEM_FRAC=0.9 prefill / 0.55 decode,
RAIL_AFFINITY=0 on all seven workers, and SGLANG_OPT_ARGMAX_GATHER=1 on
the decode worker.
Portability: every runnable script (build/setup.sh, run/submit.sbatch,
both champion-*.sbatch) derives personal paths from SG_* env vars with
generic $USER-based defaults — no account is hardcoded anywhere. The
results/ logs, run_meta.json, and milestones/ are as-run records and
therefore contain the team account's paths.
Config delta vs 20719: the tuned decode MoE config for E=128,N=384
(build/configs/), the declared concurrency (N=108, job 21257), the
spec-mode decode flag (4,660.3 -> 4,697.8), and the argmax-gather patches
(4,697.8 -> 4,839.7). The "Fallback to triton version 3.2.0" warning is absent
from all these runs' worker logs; goodput went 22.50 -> 23.22 -> 23.30 ->
23.49 -> 24.20 req/s.
Configuration (job 22002 = 20938 stack + spec-mode decode + argmax-gather, declared N=108)

Fine-tune note: the team-trained EAGLE3 drafts (HF prometheus04/…Pilot-FP8,
…5K-FP8) were validated on-cluster (2,960 / 3,000) and later superseded by
the official Nebius release (accept 2.02 vs 1.65), which is what the final
config uses. The fine-tune pipeline and its measured sim-to-real transfer
(0.31 -> 0.11) are documented in milestones/.
Building / running
Stack: build/setup.sh (idempotent, login-node) rebuilds the overlay,
applies the four patches, installs the two tuned configs, and stages the draft
from HF. Details and md5s in build/build.log. Prerequisites: a pip venv
(default ~/venv-sglang, or set SG_VENV), network access (pip + HF), and
patch; every path is SG_*-env-driven end to end, and step [5/5]
hard-fails if any patch or config did not land.
Job: run/submit.sbatch — a single Slurm script in which deploying the stack
and invoking the official AIPerf command are consecutive steps. It reproduces
the 4,839.7 run; the deltas along the chain were the tuned MoE config file
that build/setup.sh installs, the declared concurrency, the spec-mode flag,
and the argmax-gather patch (env-gated on the decode worker).
bash build/setup.sh # overlay + patches + configs + slurmconf + draft
sbatch run/submit.sbatch # deploy + official AIPerf, one job
Paths are parameterized (SG_REPO_ROOT, SG_OVERLAY, SG_DRAFT,
SG_SLURMCONF); defaults are generic ($USER-based) and match the team
account layout on this cluster.
Cold-account behavior (reproducing the score from scratch)
The job is self-contained except for the cluster-provided images/model and the
persistent per-worker caches under ${ROOT}/jitcache/home/* (Triton/DeepGEMM
JIT). The harness states its own coldness in the log:
DeepGEMM cache: 0 entries (0 = COLD, expect a slow first run)
Job 22002 ran with warm caches (ready at 510 s). On a brand-new account the first deploy pays the compiles during warmup and may not fit the 17-minute wall. Recommended sequence:
bash build/setup.sh # once
PREWARM=1 sbatch run/submit.sbatch # deploy + smoke only; warms caches
sbatch run/submit.sbatch # scored run — reproduces 4,840 (N=108, spec-mode decode + argmax-gather)
PREWARM=1 exits right after the PD smoke gate (before the benchmark); the
scored run never sets it. The same script, same official command — only the
cache state differs.

| chunked-prefill-size 16384 (prefill) | TTFT p50 588 -> 655 ms, input tok/s 100.0k -> 97.9k, score 4,839.7 -> 4,746.9 — shapes > 8k fall off the tuned MoE table and the start-of-window wave drain is unchanged | reverted (job 22119) |
| DP8/EP8 + DeepEP prefill (8v8 rebuild) | 58.6k input tok/s on 8 GPUs vs 79.4k for 4x TP2 pairs — 0.74x per-GPU; DeepEP a2a dispatch overhead is structural; the EAGLE3 draft also faults under DP8 | closed (jobs 21955/21956) |
| prefill admission 4 + RAIL_AFFINITY=1 | frac 0.9442 vs 0.9545, TTFT p99 3,420 vs 3,655 ms — wash; the tail is a ~1% multi-second stall class, not admission or rail | closed (job 21970) |
| fused qk-norm-rope / moe-sum-AR flags | qk-norm-rope: CUDA-graph capture crash; moe-sum-AR alone (decode): runs but ITL 17.68 -> 18.24 ms, score 4,839.7 -> 4,603.6 — the fused kernel is slower than separate moe_sum + custom-AR-v2 | closed (job 22346) |
| MoE retune expectation | decode MoE already ~HBM-bound; retune = single-digit % | bounded |
Submission logistics (per the organisers, Oct 2026)
- Oct 9 deliverable = presentation slides, job scripts, and the logs that support the reported results. It is used to plan the online interviews — it is not the final package.
- The full package (docs, code, scripts, logs, run instructions) is due after the interview, when result reproduction starts.
- How to submit: a folder on Google Drive (or similar) shared with
pengzhiz@hpcadvisorycouncil.com; upload plain files, not a zip; the folder may keep being updated after Oct 9, up to the interview. Mirror:huggingface.co/datasets/prometheus04/apac-submission-build. - Both tasks (HPC + AI) are scored separately; this folder covers the AI task.
