MiniMax-M3 MXFP8 full sweep config for GB300#1735
Conversation
Add minimaxm3-fp8-gb300-dynamo-vllm to nvidia-master.yaml with 7
topologies covering the full concurrency range:
- TP4/TP8 (low latency, conc 4-64)
- TP4+EP4 agg + 1P+1D disagg 2-node + 1P+1D collocated (mid, conc 64-512)
- DEP4/DEP8 (high throughput, conc 256-2048)
All recipe YAMLs included under minimax-m3-gb300-fp8/{1k1k,8k1k}/.
GB300 recipes include srun_options mem=0 (CW DefMemPerCPU cgroup fix)
and omit safetensors-load-strategy prefetch (host-memory limit).

Thanks for the contribution! For vLLM & SGLang, please ensure that your recipes is similar to the official vLLM recipes and/or the SGLang cookbook If it is not, please create a PR first before we can merge your single node PR into the master branch. Let's ensure that the documentation is first class such that the entire ML community can benefit from your hard work! Thank you
PR authors are responsible for ensuring that after merging, all GitHub Action jobs fully pass. A lot of the time, failures are just flakes and simply re-running the failed jobs will fix it. If re-running failed jobs is attempted, PR authors are responsible for ensuring it passes. See GitHub's docs on re-running failed jobs: https://docs.github.com/en/actions/how-tos/manage-workflow-runs/re-run-workflows-and-jobs#re-running-failed-jobs-in-a-workflow As a rule of thumb, generally, PR authors should request a review & get a PR approval from the respective companies' CODEOWNERS before requesting a review from core maintainers. If additional help is needed, PR authors can reach out to core maintainers over Slack. |

srun_options.mem=0 only grants a step the job's existing allocation; on gb300-cw (DefMemPerCPU=4096, no DefCpuPerGPU) the job itself was only allocated 4 GB/node and workers were cgroup-OOM-killed during engine init (run 27452273567: oom_kill in StepId=7409.7 on slurm-gb300-133-193, worker RLIMIT showed 4194304 KB). The canary passed because it landed on gb300-nv, which doesn't enforce the cap. Mirrors the sbatch_directives block of the DSV4 agentic recipes.

…h_model lock race With the mem fix in place, run 27452976271 cleared the OOM but hit a new failure: both nodes of the TP8-2n job called dynamo fetch_model within 200ms (191 @ :23.637, 193 @ :23.833), 191 took the per-blob .lock on the shared /mnt/vast/hf-home cache and held it verifying the 444 GB snapshot, 193 retried ~6.4s and died 'Lock acquisition failed' (dynamo's rust hub doesn't wait like Python hf_hub). The launcher already pre-stages and verifies the snapshot offline before submit, so the workers never need to fetch. Setting HF_HUB_OFFLINE=1 in every worker env block makes dynamo serve cache-only and skip the download lock entirely, so co-fetching workers no longer collide. Applied to all agg + disagg (prefill/decode) env blocks across the 11 recipes.

The previous pin 062a5de9 (set by #1571 "chore: agentx v0.3") was the cjq/agentx-v0.3 tip on 2026-06-02, but that branch was later rebased/ force-pushed (now at ff2b646c) which orphaned 062a5de9; GitHub has since garbage-collected it. It is now unfetchable ("upload-pack: not our ref") and absent from every CI runner cache, so actions/checkout fails on any cold runner with "Unable to find current revision in submodule path utils/aiperf" (e.g. the newly-added gb300-cw runner-4, run 27453693856). Re-pin to the current cjq/agentx-v0.3 tip — the branch .gitmodules already declares, which is live/fetchable and contains the prior aiperf history as an ancestor. This makes the pin and the declared branch consistent again.

Replace the aggregated M3 GB300 topologies with disaggregated-only, and enable NixlConnector KV transfer over multi-node NVLink on every disagg recipe. On gb300-cw the cross-node prefill->decode KV handoff was silently falling back to RDMA/TCP (~268 MB/s, ~1400 tiny descriptors for M3 MSA cache) — the disagg ceiling. Setting UCX_CUDA_IPC_ENABLE_MNNVL=y plus --enable-cumem-allocator (VMM-registers KV so NIXL uses cuda_ipc across the NVL fabric) lifts it to ~1.4-1.7 GB/s and gives +17% / +23% / +49% out tok/s/gpu at conc 64 / 128 / 256 (jobs 7490 base vs 7493 MNNVL, 1P1D TP4EP4). This is a GB300-only win: B300 8-GPU IB islands cannot move KV over multi-node NVLink. Sweep (1k1k), all MNNVL: - 1P1D TP4+EP4 collocated 1n (8 GPU), conc 8-256 - low/mid latency - 1P1D TP4+EP4 split 2n (8 GPU), conc 64-512 - mid throughput - 1P + DP16+EP wide decode 5n (20 GPU), conc 512-2048 - max throughput (decode keeps scaling on NVL where 1P1D saturates: ~1213 vs ~810 out tok/s/gpu @ conc 1024) Removes all agg-gb300 recipes (1k1k + 8k1k); applies MNNVL to the 8k1k disagg recipe too for consistency.

All prefill workers switched to DEP8 (TP1 DP8 EP, 8 GPU, 2 nodes). Low conc (<128): two decode variants — TEP8 (TP8+EP8) and TP8+Marlin. High conc (128+): DEP8 decode, 2P+7D = 18 nodes. TP8 decode (not TP4) to avoid Marlin OOM seen on previous run. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

TEP8 cudagraph limits too high
High Severity
Four 1k1k TEP8 decode recipes still set max-num-seqs: 4096 and max-cudagraph-capture-size: 8192, while the same change documents GB300 MiniMax-M3 graph capture OOM from those magnitudes and caps DEP decoders at 512/2048. Decode startup can hit CUDA OOM during graph capture before benchmarks run.
