Use `--extra workflows` for GitHub integrations - Every priority-scheduled self-hosted job requests exactly one `nodes:N` label (physical Slurm nodes; single-node is `nodes:1`, multi-node forwards `node-count`). A queued job without the label is ineligible for priority scheduling, and labels cannot be added later; fix the branch and dispatch again. - A change that alters what any benchmark runs needs a `perf-changelog.yaml` entry for the affected config keys; the entry triggers result collection. Refactors, recipe moves, and docs need none. `python -m infx.matrix.changed --base origin/main` (from `inferencex-e2e/`) lists affected config and recipe keys; if it lists none, add no entry. It does not see script or launcher code, so judge script and launcher changes by what they run. - `perf-changelog.yaml` is append-only and byte-sensitive: preserve every existing byte and separator, append only at the tail, and resolve conflicts only with the [changelog conflict helper](.github/workflows/README.md#changelog-conflict-recovery). One PR has at most one block (listing one or more `config-keys`); revise it rather than adding another. New entries are English-only (the bilingual rules do not apply); leave historical entries unchanged. +- Use `append-only: true` when a PR only adds points to an existing curve and rerunning the curve would waste cluster time. For example, an existing GB300 curve has 12 points that took 12 hours to run; adding a 13th concurrency runs only that point and extends the latest curve. Existing points, the image, and any shared logic that can affect them must stay unchanged; otherwise use a regular entry and rerun the full curve. See [append-only](CONTRIBUTING.md#adding-points-to-the-latest-curve-with-append-only). - **`main` never runs sweeps.** A PR with a changelog entry needs an accepted `/use ` before merge, or its results are never ingested. Merge with `infx.workflows.merge_with_reuse`, except external PRs (pin their `e2e-tests.yml` run explicitly), ingest-recovery PRs (merge directly, per the [recovery command](.claude/commands/recover-failed-ingest.md)), and retirement-only PRs (all new entries have `retired: true`; merge directly after review and checks, with no `/use` or database ingest).

NCCL EP sizes its group to the ladder's top and runs every rung. DeepEP V2's receive is sized -from a constant rather than the ladder, so clamping around a kernel defect cannot change the -footprint. That was used once: DeepEP's low-latency combine corrupted the 256 rung on every -Blackwell SKU until the pin moved to upstream main with -[DeepEP #642](https://github.com/deepseek-ai/DeepEP/pull/642), a CTA-scope fence before the combine -staging buffer is recycled. +`workload.ladder_measured`, `ladder_dropped` and `ladder_cap` record what ran. DeepEP V2, UCCL-EP and +MoRI allocate their low-latency receive at 256 tokens per rank (vLLM's batched-DP budget), so those +ladders stop at 256. NCCL EP sizes its group to the ladder's top and runs every rung. + +### Unmeasured Cases + +Eleven registered EP cases have no published result: + +- **h100-dgxc EP16 prefill, deepep-v2 `normal` and nccl-ep `low-latency`** (four cases): they do not + finish through the EFA proxy inside `COLLX_RUN_TIMEOUT`. +- **mi355x mori EP16** (six cases): two-node MoRI does not start on the vLLM v0.32.0 ROCm image until + the hosts' AINIC user space matches the image's. +- **mi325x uccl-ep `low-latency` EP16 FP8**: UCCL stalls before the first measurement + ([uccl-project/uccl#1111](https://github.com/uccl-project/uccl/issues/1111)); BF16 runs. ### Precision -Combine is always BF16. Dispatch is a BF16 control plus, on backends whose FP8 dispatch is supported -upstream, an FP8 dispatch (`BACKEND_PRECISIONS` in `sweep_matrix.py`). Every FP8 codec is per-128-block -e4m3 with FP32 scales on the wire: 7168 value bytes plus 224 scale bytes per copy. - -- **MoRI** quantizes as vLLM's MoRI `prepare()` does for a block-quantized model (aiter `per_1x128`), - in e4m3fnuz on gfx942 and OCP e4m3fn on gfx950. -- **UCCL-EP** quantizes per token and per 128 channels, e4m3fnuz on gfx942 and e4m3fn elsewhere. -- **Blackwell low-latency** (DeepEP and UCCL-EP) rounds scales to powers of two and hands the receiver - packed UE8M0 exponents, as vLLM's DeepEP LL path asks when its expert GEMM takes UE8M0 scales. The - wire still carries FP32 scales. Those rows carry the `-ue8m0` generation suffix. -- **`normal`-mode codecs** of DeepEP V2, UCCL-EP and FlashInfer EP keep unrounded FP32 scales, where - vLLM rounds them on its DeepGEMM E8M0 path: byte-identical and timing-neutral, not bit-identical. -- **NCCL EP** uses its internal DS_FP8E3M4 recipe, for low-latency prefill and decode, with a BF16 - combine. FP8 dispatch zero-copies under the same conditions as BF16, registering both the token and - scale windows. It runs in the default matrix as a library row: TensorRT-LLM's `NcclEP` sends - DeepSeek-FP8 activations in BF16. NCCL EP's normal mode stays BF16-only. - -The caller-side quantize is **inside the measured dispatch**, because a forward pass pays it on the -critical path. On DeepEP V2, UCCL-EP, FlashInfer EP and MoRI it is one compiled kernel, checked -bitwise against its eager reference before timing. The DeepEP V2 and UCCL-EP low-latency kernels -quantize internally. So an FP8 `normal` dispatch covers quantize plus transport, and its BF16 -control covers transport alone. Read that charge as a fixed per-call cost, not a payload-proportional -one, and compare FP8 with BF16 at the top of the ladder: at small T the FP8 path moves fewer bytes but -carries the quantize launch, and by T=512 the halved payload repays it. - -`implementation.fp8_consume` names the FP8 consumption the chained roundtrip models. `native`, the -default, has the expert GEMM consume the dispatched FP8 and scales directly, as vLLM and SGLang do for -this 128-block shape. `CX_FP8_CONSUME=dequant` stages every pair from its own dispatch, modelling -vLLM's quant-format mismatch fallback. It is a verification hatch, not a second metric, because the -mismatched cost is derivable from what every run emits (`dequant roundtrip ~= roundtrip + stage`, -within 2.4% on b200). The reverse does not hold, so measure native and derive dequant. +Combine is always BF16. Dispatch is a BF16 control plus, where FP8 dispatch is supported upstream, an +FP8 dispatch (`BACKEND_PRECISIONS` in `sweep_matrix.py`). Every FP8 codec is per-128-block e4m3 with +FP32 scales: 7168 value bytes plus 224 scale bytes per copy. + +- **MoRI** quantizes as vLLM's MoRI `prepare()` does (aiter `per_1x128`): e4m3fnuz on gfx942, e4m3fn + on gfx950. **UCCL-EP** uses e4m3fnuz on gfx942 and e4m3fn elsewhere. +- **Blackwell low-latency** (DeepEP, UCCL-EP) rounds scales to powers of two and hands the receiver + packed UE8M0 exponents, as vLLM asks; rows carry `-ue8m0`. +- **`normal`-mode codecs** keep unrounded FP32 scales where vLLM rounds them: timing-neutral, not + bit-identical. +- **NCCL EP** uses its internal DS_FP8E3M4 recipe in low-latency only, as a library row (TensorRT-LLM + sends DeepSeek-FP8 activations in BF16). + +The caller-side quantize is **inside the measured dispatch**, since a forward pass pays it. An FP8 +`normal` dispatch therefore covers quantize plus transport and its BF16 control transport alone; +compare the two at the top of the ladder, where the halved payload repays the quantize launch. + +`implementation.fp8_consume` is `native` by default: the expert GEMM consumes FP8 directly, as vLLM +and SGLang do. `CX_FP8_CONSUME=dequant` stages every pair from its own dispatch, as vLLM's +quant-format mismatch fallback does. It is a verification hatch, not a second metric +(`dequant roundtrip ~= roundtrip + stage`). ## Backends Each backend runs the configuration its reference engine selects: vLLM, except TensorRT-LLM for NCCL -EP low-latency (as of NVIDIA/TensorRT-LLM#20631; see [nccl-ep.md](nccl-ep.md)). -`implementation.maturity` is `production` where an engine can select the configuration today and -`candidate` where the row describes the library ([Result Document](#result-document)). Compare -`production` rows for deployed contracts. +EP low-latency ([nccl-ep.md](nccl-ep.md)). Backend source pins live in `runtime/common.sh` and are +enforced by exact fetched-commit comparison; each adapter's import probe rejects any other build. ### DeepEP V2 -DeepEP V2 is the `ElasticBuffer` of [DeepEP #605](https://github.com/deepseek-ai/DeepEP/pull/605). -The pin in `runtime/common.sh` is upstream `main`, which also carries #630 (pure scale-up init without -GIN), #640 (NCCL shared-memory mappings) and #642 (the low-latency combine fence). The adapter fails -closed unless the loaded `deep_ep` exposes `ElasticBuffer`, which also catches an image-bundled -`deep_ep` shadowing the build. - -On b300 (registry `deepep_efa_fork`) the build uses AWS's fork instead, -[amazon-contributing/DeepEP](https://github.com/amazon-contributing/DeepEP) `main`: the same pin plus -its EFA commits. Upstream treats EFA as unsupported -([deepseek-ai/DeepEP#369](https://github.com/deepseek-ai/DeepEP/issues/369)), and its scale-out -kernels assume writes land in order. The fork's default `unordered` kernels batch each put with an -in-band header and count completions, which the aws-ofi-nccl proxy's weak signals support; it also -caps the scale-out GIN contexts at 17. It builds against NCCL 2.32.3, whose headers declare the GIN -signal requirements the fork sets. These rows carry the `-aws-efa-fork` series suffix and record -`deepep_source` and `hybrid_kernel`, so they never pool with upstream rows. The fork is not what vLLM -ships, so there `normal` keeps vLLM's call configuration on AWS's kernels. h100-dgxc stays on upstream: -on its p5 nodes (32 EFA NICs each) the fork's unordered dispatch times out forwarding scale-out tokens. - -`normal` runs vLLM's `deepep_v2` configuration (`library_config.engine_contract = "vllm"`). With CUDA -graphs on, vLLM's default, every batch, prefill as well as decode, dispatches with `do_cpu_sync=False` -and `do_expand=False` into a receive bounded at the next power of two of T, with -`prefer_overlap_with_compute=False` (DeepEP then sizes its kernels at 64 SMs) and -`allow_multiple_reduction=False`. No deepep-v2 dispatch waits on the host. Decode replays a graph and -prefill runs eager, as vLLM runs large prefill batches uncaptured. - -Scale-up cases request NCCL Device API LSA and fail closed unless the LSA team covers the whole EP -world, which is also what makes the hybrid choice match vLLM's autoselect: DeepEP goes hybrid only -when the LSA team is smaller than the world. x86 EP16 is that hybrid path, GIN across two scale-out -domains of eight scale-up ranks each. GB EP16 stays inside MNNVL and uses LSA. Hybrid EP16 allocates -33 GIN QPs per peer (a fixed 512-QP budget) instead of the automatic 65/129, which exhausts the -per-NIC QP budget on CX-7. DeepEP's SM model reads the scale-out rate from an `ibstat` probe that cannot -see EFA and that the vLLM image does not ship, so on the EFA pools, h200-dgxc and b200-nscale the -registry's `network.rdma_gbs` supplies the per-GPU rate and the resulting count is passed explicitly -(`library_config.sm_model_rdma_gbs`). - -**A virtualized pool can make a scale-out row measure the hypervisor.** ElasticBuffer registers its GIN -window `NCCL_WIN_STRICT_ORDERING`, which strips PCIe relaxed ordering; in h200-dgxc's KVM guests -strict-ordered GPU-NIC writes cap near 10 GB/s per GPU. The build patches the registration behind a -switch a pool opts into with `rdma_relaxed_ordering` in its `network` block: h200 bf16 decode at T=512 -drops from 3088 µs to 620 µs per roundtrip, oracle green in both precisions. Upstream made the window -strict on purpose (DeepEP #661/#674), since a relaxed GIN signal can in principle overtake its data; -that race has not been reproduced, and a passing oracle does not rule it out. Those rows carry -`-relaxed-ordering` and never pool with the strict series. - -`low-latency` drives the legacy `deep_ep.Buffer` IBGDA decode kernels, which deliver a per-expert -padded receive and apply the gate weights inside a source-side combine (weighted-kernel-sum). It -builds and calls them as vLLM's `deepep_low_latency` path does: `num_qps_per_rank` equal to the local -expert count, NVLink allowed, MNNVL allowed only on the GB pools (`VLLM_DEEPEP_LOW_LATENCY_USE_MNNVL`), -and each collective split into a send kernel and a receive hook that runs straight after it. EP8 -runs over intra-node NVLink; multi-node EP16 rides NVSHMEM IBGDA, which wants gdrdrv on the node -(b200-nscale's bare-metal IB has it), and GB EP16 stays inside MNNVL. B300 registers no DeepEP -low-latency: the legacy Buffer initializes NVSHMEM with an RDMA transport even on one node, and -NVSHMEM aborts on topology detection over B300's EFA. +The `ElasticBuffer` of [DeepEP #605](https://github.com/deepseek-ai/DeepEP/pull/605), pinned to +upstream `main`.

Rows carry `-aws-efa-fork` + and record `deepep_source` and `hybrid_kernel`. +- **h200-dgxc** opts into `rdma_relaxed_ordering`: ElasticBuffer's strict-ordered GIN window caps + GPU-NIC writes near 10 GB/s in the KVM guests. The patch removes that cap, but upstream chose strict + ordering on purpose (DeepEP #661/#674), and a passing oracle does not rule out the race. Rows carry + `-relaxed-ordering`. ### UCCL-EP -[UCCL](https://github.com/uccl-project/uccl) EP is an API-identical DeepEP replacement that keeps the -legacy `Buffer` but routes scale-out over CPU proxies issuing GPUDirect RDMA on plain `libibverbs`. -Its scale-up is single-node `cudaIpc`, never MNNVL, and proxies start only across nodes. No engine -ships a UCCL selector, so its rows stay `candidate`, but engines deploy it as a drop-in `deep_ep` -under vLLM's DeepEP backends, and the adapter runs that configuration. - -`normal` is vLLM's `deepep_ht` path: UCCL's default 20 SMs, `get_dispatch_config`/`get_combine_config` -per call, 1 GiB of NVLink buffer, plus 1 GiB of RDMA buffer and 10 QPs per rank across nodes. Its -dispatch polls receive counters on the host before launching the transfer, so `normal` stays eager and -passes through the host gate ([Rank Alignment](#rank-alignment)). `low-latency` issues the same calls -as DeepEP V2 (send kernel plus receive hook) with vLLM's 256-token receive; at EP8 `is_intranode` -keeps it on NVLink. UCCL-EP is built from source at its pin with UCCL's drop-in flags -`USE_DMABUF=1 PER_EXPERT_BATCHING=1`; `implementation.library_version` names the commit and flags, -and the import probe rejects any other `deep_ep`. - -**h200-dgxc EP16 runs a deeper RDMA receive ring than vLLM.** With vLLM's dispatch config (RDMA -chunks send 20 / receive 140), BF16 prefill deadlocks inside UCCL on every attempt: the sender -coordinator waits for a full chunk the senders cannot prepare, and the receiver for tokens that are -never delivered ([uccl-project/uccl#1110](https://github.com/uccl-project/uccl/issues/1110)). A -receive ring of 1040 tokens (a multiple of the send chunk) is deep enough that no prefill stream -wraps, and every rung passes the oracle. The registry's `network.uccl_rdma_recv_tokens` sets it for -h200-dgxc only; those rows carry `-rdmarecv1040` in `kernel_generation` and the realized config in -`library_config`, so they are library rows rather than vLLM's configuration until UCCL is fixed. - -UCCL-EP EP16 is not registered on mi355x: its CPU-proxy RDMA works over the Pollara fabric but runs -about 13x under UCCL's documented bandwidth, unchanged by registration mode or traffic class (an -ionic-driver suspect). +[UCCL](https://github.com/uccl-project/uccl) EP is an API-identical DeepEP replacement whose scale-out +runs over CPU proxies issuing GPUDirect RDMA; scale-up is single-node `cudaIpc`, never MNNVL.

Rows carry + `-rdmarecv1040` and are library rows until UCCL is fixed. +- mi355x EP16 is not registered: it runs about 13x under UCCL's documented bandwidth. ### MoRI -`normal` runs vLLM's MoRI configuration (`MoriAll2AllManager`) under MoRI's default MANUAL launch mode. -One node runs IntraNode at block_num 80, rdma_block_num 0 and 16 warps per block; two nodes run -InterNodeV1 at 64/32/8 on gfx950 (32/16/16 on gfx942). One QP per PE, an external input buffer and -combine `quant_type` `none`. `library_config` records the tuple the handle realized, and the adapter -fails closed if it differs from the request. - -Warp count and buffer mode are pinned together: MoRI's tuning keys combine on `zero_copy`, and 16 -warps loses 13-78% against 8 with a registered buffer but wins 9-27% from T=128 up with the external -input the engines run. These rows describe the engine-integrated configuration, not MoRI's peak: -its shipped per-shape tables reach a faster combine (0-15% depending on arch) with tuples no engine -selects. - -MoRI EP16 runs InterNodeV1 across two nodes with the STATIC_HEAP symmetric heap, and a scale-out case -fails closed under any other heap mode: `VMM_HEAP` corrupts cross-node combine on ROCm 7.2, where uncached VMM allocations -read stale lines (ROCm/mori#610). `combine()` takes the rank's own routing tensor, never dispatch's -recv-slot indices, because InterNodeV1 keys its node predicate by the rank's own token id -(ROCm/mori#475). `low-latency` follows vLLM's `mori_low_latency`, which differs only across nodes: -`InterNodeV1LL` with the arch's tuple, so MoRI has no EP8 low-latency cell. `MORI_ENABLE_SDMA` stays -unset, as vLLM leaves it; a row run with it set carries `-sdma`. +`normal` runs vLLM's `MoriAll2AllManager` under MANUAL launch mode: IntraNode on one node (block_num +80, rdma_block_num 0, 16 warps), InterNodeV1 on two (64/32/8 on gfx950, 32/16/16 on gfx942), one QP +per PE, external input buffer. The adapter fails closed if the realized tuple +(`library_config`) differs. These are the engine-integrated tuples, not MoRI's peak tables. + +EP16 requires the STATIC_HEAP symmetric heap (`VMM_HEAP` corrupts cross-node combine on ROCm 7.2, +ROCm/mori#610). `low-latency` follows vLLM's `mori_low_latency`, which differs only across nodes +(`InterNodeV1LL`), so MoRI has no EP8 low-latency cell. `MORI_ENABLE_SDMA` stays unset; rows run +with it carry `-sdma`. ### NCCL EP -NCCL EP is NVIDIA's MoE dispatch/combine on the NCCL Device API, shipped as the `nccl-extensions` -wheel. [nccl-ep.md](nccl-ep.md) documents its engine contract, row identity and wheel pin. It runs EP8 -and EP16 on all six NVIDIA SKUs: EP16 stays inside MNNVL on GB200/GB300 and is a 2x8 scale-out over -the cross-node GIN path on H100, H200, B200 and B300. - -`normal` selects `HIGH_THROUGHPUT`, whose FLAT receive and unweighted rank-sum combine match -`layout-and-dispatch-v1`. No engine runs it, so HT rows are `candidate`. Its timed dispatch carries -`ncclEpUpdateHandle`, the per-step routing update the API requires before every dispatch whose -routing changed, as every backend's dispatch carries its routing work. The update's HT work is sized -by the handle's capacity, not by T, so every rung carries a term set by the ladder's top. NVIDIA's -`ep_bench` excludes it. - -`low-latency` runs TensorRT-LLM's `NcclEP` configuration: rank-major receive with caller-side weighted -pre-reduction, an unweighted rank-sum combine, and one group sized to the ladder's top. Dispatch writes -a registered window directly within one LSA/MNNVL domain, graphed or eager, and scale-out stages, as -TensorRT-LLM does with NVIDIA/TensorRT-LLM#20631. The v0.2 wheel ships the combine fence the v0.1 -port lacked, so the ladder runs unclamped. The adapter binds one handle per group and rebinds it per -point, because two handles from one group share its double-buffer parity slots -([NVIDIA/nccl#2303](https://github.com/NVIDIA/nccl/issues/2303)). +NVIDIA's MoE dispatch/combine on the NCCL Device API (`nccl-extensions` wheel); [nccl-ep.md](nccl-ep.md) +has the full contract.

Dispatch writes a + registered window directly within one LSA/MNNVL domain and stages across nodes. ### FlashInfer EP -FlashInfer EP is TensorRT-LLM's one-sided MNNVL `MoeAlltoAll` from FlashInfer 0.7.1, vLLM main's pin: -each rank writes tokens directly into its peers' workspace windows, so it is GB200/GB300-only and runs -EP8 and EP16 inside MNNVL. It has one kernel family, so it runs `normal` only, across both ladders. -It runs vLLM's integration (`flashinfer_nvlink_one_sided`): combine is handed a caller-owned payload -with `payload_in_workspace=False`, so FlashInfer's staging copy into the workspace runs, and is timed, -inside `combine`, as in vLLM (writing the expert output into the workspace directly is TensorRT-LLM's -path). FP8 dispatch is DeepSeek blockwise FP8 carried as a fourth payload (vLLM v0.29.0+). Through -0.6.15 the combine accumulates in BF16 with a pairwise slot tree, which the oracle models exactly -(`combine_reduction = "topk-slot-tree"`); 0.6.16 moved to FP32, and the adapter picks the model from -the installed version. Graph replay cuts gb200 EP8 T=1 from 151 µs to 43 µs, so decode replays. +TensorRT-LLM's one-sided MNNVL `MoeAlltoAll` from FlashInfer 0.7.1 (vLLM's pin): every rank writes into +its peers' workspaces, so all ranks share one NVLink domain (EP8 on one node, EP8 and EP16 on +GB200/GB300). `normal` only, on both ladders, through vLLM's `flashinfer_nvlink_one_sided` +integration, so the staging copy into the workspace is timed inside `combine`. FP8 dispatch carries +DeepSeek blockwise scales as a fourth payload. ## Workload Identity -One deterministic workload is generated over the global token batch from the workload's seed and -sliced by source rank. A keyed BLAKE2b counter over (token, slot, attempt, stream) gives byte-identical -expert indices and gate weights on every runtime, and the harness proves the routing trace identical -across ranks before a case can succeed. Token-expert assignments (expert compute load) and -rank-deduplicated token copies (EP activation traffic) are kept distinct; adapters may not generate -routing or reinterpret one as the other. +One deterministic workload is generated over the global token batch from the seed and sliced by +source rank. A keyed BLAKE2b counter gives byte-identical expert indices and gate weights on every +runtime, and the routing trace must match across ranks before a case can succeed. Adapters may not +generate routing. ## Measurement -Every window is a pair of CUDA events on the stream. `roundtrip` means dispatch then combine, the -transport. Expert-output staging is outside it and outside isolated combine, and is reported as its -own `stage` component where it does device work (the `dequant` hatch puts it back on purpose). +Every window is a pair of CUDA events. An event costs device time of its own: two adjacent event +nodes in a replayed graph sit 2.4 to 3.3 µs apart on NVIDIA GPUs and about 6 µs on AMD, and a window around +real kernels carries more. Every windowed number includes that cost; only the pair period is +measured without an event between its pairs. -**`stage` is harness scaffolding, not a serving phase.** Under FP8 it converts the received payload -to the BF16 combine sends, standing in for the expert GEMM that reads FP8 natively in production. Do -not sum it into a total or compare it across backends: each adapter converts a different amount (only -the received rows, the whole padded plane, or, for FlashInfer, only filled slots). -`implementation.stage_excluded_from_roundtrip` means device-work staging existed and was hoisted out; -`false` covers both "nothing to stage" (every BF16 row) and the `dequant` hatch. `isolated_sum` is -derived: isolated dispatch plus combine, never `stage`. +`roundtrip` is dispatch then combine. Expert-output staging is +outside it and is reported as `stage` where it does device work. Under FP8, `stage` converts the +received payload to BF16 in place of the expert GEMM; each adapter converts a different amount, so do +not compare or sum it. `isolated_sum` is isolated dispatch plus combine, never `stage`. -Each point measures two families: +![How CollectiveX times dispatch and combine](img/ep-timing-methodologies.svg) -- **Fresh entry** (`roundtrip`, `dispatch`, `combine`, and eager `stage`): one aligned call per - sample, reduced across ranks by MAX, because a layer finishes with its slowest rank. - [Rank Alignment](#rank-alignment) describes how each sample opens. -- **Chained** (`pair_period`, `chain_floor_us`, `chain_health`): pairs issued back to back with no host - sync, as a decode loop issues them. `pair_period` is the **headline** for every row, graphed or - eager. See [Chained Pair Period](#chained-pair-period). +The diagram ([source](img/ep-timing-methodologies.excalidraw)) shows the published windows: -![One fresh-entry sample](img/fresh-entry.svg) +1. **Fresh entry** (`roundtrip`, `dispatch`, `combine`): one aligned call per sample, reduced across + ranks by MAX (a layer finishes with its slowest rank). `combine` runs behind an untimed dispatch. +2. **Stage**: eager FP8 rows only. +3. **Chain floors** (`chain_floor_us`): events around each op, MIN across ranks. +4. **Pair period** (`pair_period`), the headline: back-to-back pairs between two events, MEDIAN + across ranks. -Every row also carries `cross_rank_min_us` (the same samples reduced by MIN) and -`cross_rank_spread_us` (roundtrip MAX minus MIN). Alignment removes entry skew, but ranks still leave a -window unevenly, so read MAX and MIN as a bracket: two cells whose MAX gap is smaller than the larger -spread are not separated by the data. Do not rank multi-node decode cells on p99 of MAX, which -worst-rank stalls dominate. The isolated `dispatch` and `combine` inherit the preceding op's exit -stagger, so treat them as diagnostics; the paired roundtrip is the comparable fresh-entry quantity. +Every row also carries `cross_rank_min_us` and `cross_rank_spread_us`. Read MAX and MIN as a bracket: +two cells whose MAX gap is smaller than the larger spread are not separated. Isolated `dispatch` and +`combine` inherit the preceding op's exit stagger, so treat them as diagnostics. ### CUDA Graph Replay -Serving engines capture their decode step, so graph-compatible pairs replay `CUDAGraph.replay()` at -decode by default, as each backend's engine captures it. Prefill stays eager everywhere, as engines run -it, and `COLLX_CUDA_GRAPH=0` restores eager everywhere. - -- **deepep-v2** `normal` and `low-latency` decode. -- **nccl-ep** low-latency and HT decode. Graphed low-latency within one domain takes the window path - (`-zc`), as TensorRT-LLM's captured decode does with #20631; scale-out stages.

Capture uses torch's default `global` error mode, as vLLM's and SGLang's decode captures do, -so a capture-unsafe call fails instead of being recorded. Graphed rows carry `-cudagraph-spin-ar` on -`kernel_generation` and eager rows `-eager-spin-ar`, so the two never pool. +Engines capture decode, so graph-compatible decode pairs replay CUDA graphs; prefill stays eager +everywhere, and `COLLX_CUDA_GRAPH=0` forces eager. Graphed: deepep-v2 (both modes), nccl-ep (both +modes; HT runs NCCL graph usage mode 1, `-gum1`), mori (both modes), flashinfer-ep, and uccl-ep +low-latency intranode only. + +Only the launch changes. Each fresh-entry component captures one pair with the alignment ahead of its +first event; each chain sibling is one graph of 128 pairs. Capture uses torch's `global` error mode, +so a capture-unsafe call fails. Rows carry `-cudagraph-spin-ar` or `-eager-spin-ar`. ### Rank Alignment -Every fresh-entry sample opens the way DeepEP's `bench_kineto` does: a GPU spin, then a device -all-reduce, with no host sync before the start event. The spin lasts 2 ms of wall time -(`COLLX_ALIGN_SPIN_US`), calibrated after each warm-up because `torch.cuda._sleep` counts cycles. It -outlasts the host's enqueue of the sample, so the last rank to arrive already has its timed work queued -when the all-reduce releases everyone, and every window opens at the barrier's exit: entry skew and -the first kernel's launch latency both leave the window. Eager rows queue the spin and all-reduce -before each sample; graphed rows capture them in the graph ahead of its first event, so no host -handoff follows the alignment. Before the all-reduce moved into the graph, a late host launch stalled -the other ranks inside the window (gb200 flashinfer EP8 T=1 roundtrip p99 858 µs); in-graph, graphed -decode roundtrip p99 runs 1.01-1.19x its p50. That is why graphed rows publish tails. On ROCm, where -HIP submits a replay node by node from the host, the spin is what gives a lagging host time to submit -the whole replay before the barrier releases anyone. - -A sample is **missed** when some rank's host took longer than the spin to finish enqueuing its timed -work (eager) or to return from its replay call (graphed). Garbage collection is off for every timed -series. Rows publish `rank_alignment.missed_samples` per series and `missed_fraction`, and the -fresh-entry tails are withheld once missed or host-stalled samples could fill them: p99 at 1%, p95 at -5%, p90 at 10%. `implementation.rank_alignment` records the method and the spin. - -`combine` (and eager `stage`) is timed behind its own untimed dispatch, so its window inherits that -dispatch's exit stagger. A dispatch that waits on the host (uccl-ep `normal`) runs before the -alignment, so the spin is not spent on its wait. - -**Host-synced series wait out a throttled host.** In uccl-ep `normal`, the host's poll and relaunch -sit inside the window, which is their production cost. While uccl-ep EP16 runs, b200-nscale nodes -intermittently drop every core to about 200 MHz for 100-200 ms every 2-5 s (the platform's response to -uccl-ep's 32 busy-polling proxies per node; never idle, never under deepep-v2), which put ~1% of EP16 -decode samples at 1-2 ms. So each sample of these series first times a ~20 µs loop of interpreter -work outside the window and keeps probing while it runs more than 2.5x slow; the other ranks wait at -the barrier. A second probe after the sample catches a throttle that began inside it. A sample waits -at most 0.5 s and a run 60 s. Rows publish `host_held_samples` (start held more than 1 ms) and -`host_stalled_samples` (a probe more than 5x slow; these gate the tails like missed samples), with -their largest series shares; all four are null where the dispatch does not wait on the host. The probes -see only the two ends of a sample, and nothing flushes L2 between samples. - -Each chain sibling is aligned once, by the all-reduce alone when eager: a spin in front lets the host -queue a backlog the GPU drains faster than the host refills it, mixing two speeds into the kept pairs. -A graphed sibling keeps the captured spin, since its replay is one host call. In host-synced modes -each eager sibling also passes the host gate, and every rank restarts it together, up to three times, -if any host ran throttled (`chain_health.host_retried_siblings`, `host_stalled_trials`). +![One fresh-entry sample on three ranks](img/fresh-entry.svg) + +Each fresh-entry sample opens as DeepEP's `bench_kineto` does: a 2 ms GPU spin +(`COLLX_ALIGN_SPIN_US`, recalibrated after warm-up) and then a device all-reduce, with no host sync. +The spin outlasts the host's enqueue, so every rank's timed work is queued when the all-reduce +releases them, and entry skew and launch latency stay outside the window. + +A sample is **missed** when a rank's host took longer than the spin to enqueue its work (eager) or +return from its replay (graphed).

Eager chain siblings pass the same gate and +restart together, up to three times (`chain_health.host_retried_siblings`, `host_stalled_trials`). ### Chained Pair Period -Fresh-entry components start every sample from an idle pipeline. A decode loop never stops, and what it -pays per MoE layer is the pipeline's steady-state **period**. `benchmark_chain` issues dispatch→combine -pairs back to back with events enqueued on-stream and no host sync inside the loop, drops the first 16 -pairs as pipeline fill, and pools 4 trials per point over the same rotated ladder order as the -fresh-entry pass. The pairing is `run_roundtrip`'s, so `pair_period` excludes staging on the same rule -`roundtrip` does. - -![Two sibling chains](img/chained-pairs.svg) - -Each trial runs **two sibling chains** of 128 pairs, so the statistics do not carry the -instrumentation that collects them. One chain with six `record()` calls per pair charged the inner -records into the period wherever the device drained faster than the host enqueued, a roughly -T-independent 10-30 µs on every vendor at once. So a **floors chain** runs first with only the four -op-window events, and a **period chain** second with only the outer pair events, whose host cost lands -in the inter-pair gap. - -- `components.pair_period` (origin `chained-median`): each pair window, reduced across ranks by MEDIAN. - The period is a rate: the collectives phase-lock every rank into one cadence, and a MAX would publish - whichever rank hiccuped. -- `chain_floor_us.dispatch` / `.combine` (origin `chained-cross-rank-min`): each op window, reduced by - MIN. The last rank into a collective waited least, so its window is the op's floor, within ~10% of - profiler kernel time. `period - Σfloors` has meaning in both signs. Positive is per-pair inter-rank - wait, which on a synchronization-dominated backend sits flat in T (`period = max(sync budget, work)`). - Negative is the floors chain's own record cost inflating its windows where the device outruns the - host. -- `chain_health.pair_spread_us`: per-pair cross-rank spread. Large next to `pair_period` means a paced - or slow rank, and the point is not a steady-state period. -- `chain_health.interpair_gap_us`: start-to-start median minus pair-window median, the cost outside - the window and the regression guard against the six-events defect. -- `chain_health.settle_drift_us`: late-half minus early-half period, the proof that 16 dropped pairs - were enough. - -**Chained per-op medians and p99s are never published.** Without a host sync, each rank's wait parks in -whichever op window it happens to block in: stable per rank, arbitrary across ranks, bistable across -runs, while the pair period is conserved. Only the period and the MIN floor are stable. - -**The period is always free-running.** Ranks may drift by up to about one iteration, which is sound -only where the receive plane tolerates it: every backend double-buffers per dispatch, enforces strict -pairing, or completes each op on a reusable handle, and DeepEP V2 `normal` passed an un-synchronized -256-pair hand probe at EP8 and EP16 in both precisions. A backend that cannot run free needs a fix, -not a variant: re-aligning ranks between pairs adds its own ~10 µs and removes the overlap the -measurement exists to capture. - -**An eager chain can be host-bound.** Prefill chains are eager, so the host enqueues every pair. Where -its per-pair cost exceeds the GPU's pair time, the slowest host sets the cadence and the other ranks -wait inside dispatch: on GB200/GB300 the Grace host makes deepep-v2 normal FP8 prefill at T=1024 run -above its aligned roundtrip (EP8 227-229 µs against 197 µs). The aligned `roundtrip` is the transport -number there. +A decode loop pays the pipeline's steady-state **period** per MoE layer. `benchmark_chain` issues +dispatch→combine pairs back to back with no host sync, drops the first 16 as fill, and pools 4 +trials. -### Timing Profile +![Three sibling chains](img/chained-pairs.svg) -One timing profile, defined in `configs/sweep.json` and recorded in `measurement.sampling`: +Each trial runs three sibling chains of 128 pairs, so one chain's events never enter another's +numbers: the **floors chain** records op windows, the **period chain** pair windows, and the **span +chain** two events only, one before its first kept pair and one after its last. -- Fresh entry: 256 trials x 8 timed iterations = 2048 samples per component. -- Chained: 4 trials x (128 pairs - 16 dropped) = 448 pairs for the period and 448 for the floors. -- 32 full dispatch-stage-combine warm-ups before each component at every trial and point, and before - each chain trial. -- Component order rotates each trial (`trial_order`) over a per-trial-rotated ladder. -- Each fresh-entry sample is reduced across ranks by MAX before nearest-rank p50/p90/p95/p99. +- `components.pair_period` (`chained-span-median`): the span chain's time per kept pair, reduced by + MEDIAN, since collectives phase-lock the ranks into one cadence and a MAX would publish whichever + rank hiccuped.

Checks -6 and 7 exist because 2-5 see only drained calls: without them a backend that corrupts under -back-to-back pairs would present as the fastest cell.

Under FP8 -the oracle applies the backend's exact quantize round-trip to the semantic payload, so the payload match -stays bit-exact and the tolerance does not widen. Physical receive order is not a correctness property. +Any failure makes the case `invalid` (`correctness.passed`).

Run `CX_FP8_CONSUME=dequant` when an FP8 period moves without its BF16 +sibling, and before publishing a new FP8 backend. Read `correctness.chain_last_output_error` before +the verdict. + +The combine model follows `implementation.combine_reduction`: `domain-fp32` (uccl-ep, MoRI, nccl-ep +HT, FlashInfer) reduces in FP32 per scale-up domain and casts before the scale-out sum; `rank-fp32` +(deepep-v2, nccl-ep low-latency rank-major) sums per destination rank in FP32. The gate is max +relative error (denominator clamped at 0.02) below `8 * 2^-8`.

Each cache directory's name binds the CPU architecture, the image and -the pin (plus the GPU architecture and build-recipe generation for GPU builds), and it is never -committed. The DeepEP V2 build applies one local patch, the opt-in relaxed-ordering switch; UCCL-EP's -AMD build swaps managed allocations for pinned host memory. MoRI ships in the image and is only -import-checked. Runtime probes fail closed before reuse, and a cache that fails them is rejected, not -reset, so a concurrent allocation cannot lose files it is using. +Each image tag is imported once per cluster into a squash, refreshed when the registry digest moves +(`COLLX_IMAGE_REFRESH=1` forces it) and validated on each use. Backends the image does not ship are +built at their pins into a mode-0700 cache mounted as `/cx-cache`, keyed by CPU and GPU architecture, +image and pin.

The lane's shared block in [`configs/srt-recipes/`](../../../configs/srt-recipes) (`fixed-sequence-{single,multi}.yaml` or `agentic.yaml`) is merged under the fragment (under `base` for bundles). Every multi-node benchmark point on a cluster with a GPU exporter also gets a telemetry block, with the cluster's CPU exporter where it declares one, unless its recipe runs etcd and NATS on a dedicated node: [`telemetry-dcgm.yaml`](../../../configs/srt-recipes/telemetry-dcgm.yaml) where the cluster sets `srt-slurm.power-exporter-port`, else [`telemetry-native.yaml`](../../../configs/srt-recipes/telemetry-native.yaml). The binder sets `telemetry.required` only for a row with `power: true`. The fragment wins: mappings merge and lists replace, so a fragment may keep telemetry tunables such as `collector_join_timeout_seconds`. Native single-node benchmarks also get [`telemetry-native.yaml`](../../../configs/srt-recipes/telemetry-native.yaml) before variant selection. That block enables best-effort power collection with the cluster's `default_gpu_exporter`; eval-only points omit collection. A native single-node point on a cluster that declares `srt-slurm.cpu-power-exporter`, and a `cpu-power: true` row, also gets `telemetry.cpu_power_exporter` with that source. The binder sets `telemetry.required` from `REQUIRE_POWER`, so a single-node fragment may not set it, and gives AgentX clients matching power switches. 2. The row's selector picks the variant.

Fixed-sequence recipes also get `benchmark.env.ISL`/`OSL`; single-node recipes get `MODEL` and `CONC`, and fixed-sequence ones `RANDOM_RANGE_RATIO` and `USE_CHAT_TEMPLATE` (`true` exactly when the recipe speculates). Multi-node AgentX recipes get the client's `RESULT_DIR`, `AIPERF_DATASET_MMAP_CACHE_DIR` and `HF_HUB_CACHE` from the launcher, which derives them from the volumes it mounts (`volume-mounts`, `agentic-volume-mounts`, lane mounts); a fragment that sets `HF_HOME` keeps its own cache. They also get `IS_MULTINODE: "true"` and `ENABLE_AGENTX_POWER`, `"1"` exactly when the launcher collects the point's AgentX power (a `power: true` row whose lane rule collects AgentX or adapter power, or any GB200 or GB300 AgentX point the launcher measures by default) and `"0"` otherwise, and `REQUIRE_POWER`, `"1"` when the workflow requires power or the lane rule marks the point `require`, so the client fails a point whose power is invalid.
