Description

Adds a modeling_v2 (Staircase) target for GLM-5.2-NVFP4 on Rubin (sm_107) at TP16: tensor-parallel attention
and experts over 16 ranks, no attention DP, no expert parallelism, with one-model MTP-Eagle (any draft length) or no
speculative decoding. It is the generation server of a disaggregated low-latency deployment (one DEP4 context server on
the built-in implementation, one TP16 generation server on this target, modeling_v2: require).

Supersedes #20502. That PR also changed the speculative step's executor path (decoder runner, step staging, KV
cache manager V2, DSA metadata). Those changes are left out here (about 2 % of x), so this PR touches fewer shared
files.

Routing. models/glm_moe_dsa/routing.py claims GlmMoeDsaForCausalLM only for compute capability (10, 7), the
GLM-5.2 shape (78 layers, hidden 6144, 256 routed experts, q_lora_rank 2048), the TP16 mapping above and MTP-Eagle /
no speculation. Unmatched deployments get NoTarget: auto uses the built-in implementation, while require
raises instead of falling back.

Target (models/glm_moe_dsa/glm_5_2_nvfp4__sm_107__tp16/). The target owns its decoder, checkpoint loader,
and embedded MTP modules. These preserve checkpoint and cache layouts compatible with the context server.
PrefillTarget runs the GLM-owned decoder. DecodeTarget runs a one-request generation step (verify rows <= 8) on
GLM-owned kernels:

  • Attention: fused-A GEMM with the indexer's rows, q_b with FP8 RoPE in the epilogue, the KV half written straight
    into the cache, a sparse-MLA flash decode that maps the selection to cache rows itself, and o_proj publishing its
    shard for the next hop. On indexer layers q_b runs on a side stream beside the top-k; on layers that reuse a
    selection the KV half is written at entry and flash decode gathers early.
  • DSA indexer: key-sharded over the 16 ranks: K tail on a side stream, FP8 paged MQA logits on the rank's key
    shard, and an exact histogram top-k merged across ranks.
  • Communication: MNNVL Lamport hops for post-attention, post-MLP and MoE-finalize, with the residual add and
    RMSNorm fused in; an all-gather for the verify logits.
  • MLP / MoE: small-M dense MLP; the routed experts on a GLM op over the TRTLLM-Gen FC1 / FC2 kernels, with the
    router GEMV inside the routing kernel, a quantize late join and FC2 at K=128; split-K shared expert.
  • Verify logits: a split-K LM head over the vocabulary shard.
  • MTP draft loop: a target-owned MTPDraftWorker (an MTPEagleWorker subclass). For a generation step of one
    request with greedy drafting at the configured draft length, it runs the draft steps on the same kernels: a
    token-table eh_proj, a reused top-k selection after step 0, a low-M BF16 MoE for the MTP layer, and fused
    sample/glue kernels for the argmax exchange and the next step's inputs. The draft steps reuse the step's DSA
    metadata instead of rebuilding it, and the verify step's acceptance (strict count or the forced count) is one
    kernel. Every other step runs the built-in loop.

Larger batches and anything the fast path does not cover fall back to the GLM-owned modules inside the same target.

Kernels. GLM-only CUDA kernels are in cpp/tensorrt_llm/kernels/glmMoeDsa/, exposed as torch.ops.trtllm.glm_*
(cpp/tensorrt_llm/thop/glmMoeDsa/). The routed-experts op (trtllm::glm_routed_experts, glmRoutedExpertsOp.cpp)
runs the TRTLLM-Gen FC1 / FC2 kernels through their runners, so it adds no cubins and leaves the TRTLLM-Gen MoE runner
unchanged. CuTe DSL kernels live in the target's ops/. Each op is a catalog OpWrapper with certified cells and a GPU
test. GLM C++ fake registrations and the target's FP4 quantization wrapper/certificate live under its own ops/.

Workspace contracts. The routed-experts custom op declares writes to its router workspace and optional caller
output, with matching fake results and fixed internal tensor returns for functionalization. Its public list and output
sentinel behavior is preserved. Histogram scratch buffers are checked against a replacement KV manager's capacity,
page size and device, while compatible buffers retain their addresses for CUDA graph replay. Ordinary draft-workspace
setup exceptions join the existing cross-rank failure vote before the workspace is used.

Shared code changes (general, not sm-gated):

  • 3rdparty: a DeepGEMM patch so DeepJIT builds for the 10.0 family target on 10.x devices past 10.3. The bundled
    CUTLASS enables TMA and tcgen05 only for targets it knows; without this the context server's warm-up hits a device
    assert on Rubin.
  • fmhaKernels.h: the token-sparse MLA generation kernels pad the Q tile to 8 rows, as the dense MLA selection does.
    With fewer than 8 heads per rank (64 MLA heads over 16 ranks) the SmemTile check fails at warm-up.
  • modeling_v2: Arch.SM_107 and the GlmMoeDsaForCausalLM router entry. Model-specific FP4 cells and fake
    registrations are local to GLM. The shared DeepSeek model and FP4 quantize catalog are unchanged.
  • .github/CODEOWNERS: the GLM owners co-own the new GLM folders with the owners of each parent path.

Performance

Disaggregated c1 (1 ctx DEP4 + 1 gen TP16, 20 Rubin GPUs), MTP K=7 with forced acceptance 2.91 tokens/step;
x = 1000 / p90 inter-token latency (tokens/s/user). The generation server sets
sparse_attention_config.use_cute_dsl_paged_mqa_logits: false: the target scores keys with its own kernels, and the
CuTe DSL setting only adds metadata work for the built-in indexer.

Build x (tok/s/user) p50 / p90 ITL (ms)
this PR 858.4 1.122 / 1.165

Full 3600-second measurement plus request drain: 335 completed requests, zero errors.

Without this PR, main does not run this deployment on Rubin: the context server dies in the DeepGEMM warm-up, and the
built-in TP16 generation server fails the sparse-MLA SmemTile check.

Accuracy

GSM8K (1,319 questions) on the same disaggregated deployment with real acceptance: strict-match 0.9659,
flexible-extract 0.9682 (threshold 0.9). Measured acceptance length 5.53 tokens/step at K=7.

Test Coverage

  • tests/unittest/_torch/modeling_v2/models/glm_moe_dsa/glm_5_2_nvfp4__sm_107__tp16/: one GPU test per op entry over
    its certified cells, plus 4-rank matrices for the collective ops. sm_107 only; the files skip at module level
    elsewhere.
  • tests/unittest/_torch/modeling_v2/models/glm_moe_dsa/test_routing.py: GLM routing, including near misses (other shape,
    ADP, ep16, tp8, vanilla MTP, NGram, sm_103). CPU, registered in l0_cpu.yml.
  • Histogram lifecycle tests exercise profiling-to-final capacity growth, page-size changes, oversized fallback and
    CUDA graph replay with stable buffer addresses. Routed-experts tests cover mutation schemas, fake outputs and
    repeated fullgraph AOT calls with workspace and caller-output mutations. Unfinalized fullgraph tracing requires
    capture_dynamic_output_shape_ops=True; compilation coverage uses aot_eager.
  • models/glm_moe_dsa/test_draft_exchange.py: ordinary setup failures join the collective vote, control-flow
    exceptions propagate, and successful/failing workspaces keep the expected Python ownership. CPU, registered in
    l0_cpu.yml.
  • test_modeling_v2_claims.py, test_modeling_v2_no_stale_claims.py, test_modeling_v2_target_contract.py,
    thop/parallel_hw_agnostic/test_custom_ops.py (fake registrations).
  • No CI test list covers Rubin yet, so the GPU tests are local developer tests. Locally on sm_107 (4 GPUs), the list
    above passes in full against the installed wheel: 414 passed.

PR Checklist

  • Please check this after reviewing the above items as appropriate for this PR.

Dev Engineer Review

  • Adds a GLM-5.2-NVFP4 modeling_v2 target for Rubin sm_107 with TP16.
  • Adds custom attention, DSA, MNNVL, MoE, GEMM, embedding, verification, MTP, and draft-loop kernels with Torch bindings.
  • Restricts routing to the supported model shape, topology, and speculation modes. Other configurations use NoTarget.
  • Adds sm_107 registration, DeepGEMM support, sparse-MLA tile padding, CMake registration, weight loading, fake operators, and CODEOWNERS coverage.
  • Main risks include GPU synchronization, Lamport workspace rotation, cache indexing, quantization accuracy, MNNVL ownership, and fallback behavior.
  • Reported local performance is 858.2 tokens/s/user with 1.126/1.165 ms p50/p90 ITL. Reported GSM8K strict/flexible accuracy is 0.9674/0.9689.

QA Engineer Review

  • Adds SM107 GPU tests for attention, DSA, communication, GEMM, embedding, MoE, quantization, and speculative decoding.
  • Adds multi-rank certification matrices for MNNVL, DSA histogram top-k, and draft-step operations.
  • Tests cover correctness, CUDA graph replay, cache writes, workspace rotation, invalid layouts, unsupported shapes, aliasing, alignment, and out-of-range inputs.
  • Adds the routing test to tests/integration/test_lists/test-db/l0_cpu.yml.
  • Rubin GPU tests are not listed in a CI test list. The supplied evidence reports local validation with 382 passing tests.

PR effort13 points — A specialized execution target reuses existing GLM modules and checkpoint layouts, making this a feature. Sparse-MLA kernels, quantized cache updates, distributed DSA selection, Lamport synchronization and speculative selection reuse create interacting contracts warranting 13 attention-review points. The estimate remains provisional because implementation visibility is limited.
ImportanceImportant — The new sparse-MLA contract combines four-head execution, top-2048 selection and fused value projection. The visible fmhaKernels.h implementation also changes sparse generation tile selection across architectures. These introduce sensitive numerical, indexing and performance review obligations.

1503-1514: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Add a regression test for the changed dense-MLP tensor-parallel selection.

This change affects every built-in DeepSeek-V3 and V3.2 multi-node deployment, not only the GLM target. When tp > gpus_per_node and enable_fusion is true, _compute_mlp_tp_size now returns the full tp instead of capping it at gpus_per_node. The new comment calls this a correctness fix: with fusion enabled, the old cap counted each partial sum tp_size / mlp_tp_size times in the fused post-MLP all-reduce. No test in this cohort exercises this branch. A later edit could restore the cap and silently double the dense-layer outputs on multi-node TP.

Add a CPU unit test in tests/unittest/_torch/ that calls DeepseekV3DecoderLayer._compute_mlp_tp_size on a stub self. The stub needs enable_attention_dp=False and mapping.tp_size=16, gpus_per_node=8. Use intermediate_size // block_size divisible by 16. Assert these results:

  • With enable_fusion=True, the result is 16.
  • With enable_fusion=False, the result is 8.
  • With enable_attention_dp=True, the result is 1.

This test needs no GPU, so it can go in tests/integration/test_lists/test-db/l0_cpu.yml.

As per path instructions: "A bug fix without a practical regression test that would have failed before the fix." As per coding guidelines: "CPU-only tests go in l0_cpu.yml."

…ubin (modeling_v2, TP16)

Adds a modeling_v2 (Staircase) target for GLM-5.2-NVFP4 on Rubin (sm_107)
at TP16, the generation server of a disaggregated low-latency deployment:
GLM-only CUDA kernels in cpp/tensorrt_llm/kernels/glmMoeDsa exposed as
torch.ops.trtllm.glm_*, CuTe DSL ops in the target, a target-owned MTP
draft loop, and the routed experts on a GLM op over the TRTLLM-Gen FC1 /
FC2 kernels. Every other deployment keeps the built-in path.

Shared changes this deployment needs on Rubin: a DeepGEMM patch so DeepJIT
builds for the 10.0 family target on 10.x devices past 10.3, the
token-sparse MLA Q tile padded to 8 rows in fmhaKernels.h, and the dense
MLP keeping the full TP under the fused post-MLP all-reduce in
modeling_deepseekv3.py. CODEOWNERS: the GLM owners co-own the GLM folders.

Signed-off-by: Dongfeng Yu <dongfengy@nvidia.com>
Own GLM decoder, checkpoint loader, and embedded MTP construction in the target. Keep its fused dense-MLP TP behavior local and restore the shared DeepSeek model.

Group Torch bindings under thop/glmMoeDsa, move fake registrations and FP4 certification into the target, and split GLM routing tests into the model directory.

Signed-off-by: Dongfeng Yu <dongfengy@nvidia.com>
Declare router workspace and caller-output mutations with consistent fake outputs and functionalizable internal returns. Refresh histogram storage when KV-manager capacity or layout changes, and include ordinary draft-workspace setup failures in the collective vote.

Cover mutation schemas and repeated AOT calls, profiling-to-final cache growth and CUDA graph reuse, and coordinated allocation failures.

Signed-off-by: Dongfeng Yu <dongfengy@nvidia.com>
Add a model-local TP16/c1 MTP7 accuracy test with inline engine settings
and score thresholds. Require all 1319 GSM8K samples, complete request
statistics, and optimized decode/draft GPU kernels on all sixteen ranks.
Keep the probe statistics separate from corpus acceptance length.

Validation: full GSM8K on the pinned 0f5b379 runtime passed with
1267/1319 (96.0576%) for both filters and AL 5.1260543896. Freeze the
aggregate AL minimum at 95% of that reference. Independent raw-result,
GPU-trace and threshold checks passed, as did repository pre-commit.

Accept the resolved KV-cache algorithm passed by the shared modeling_v2 resolver. Claim only the FP8 latent layout supported by the target, and cover explicit dtype overrides and incompatible cache layouts.

Match the cluster epilogue helpers to the existing kernel architecture guards so multi-architecture builds do not parse SM90-only APIs for SM80, SM86, or SM89.

CI Report

⚠️ Resource Maintenance — Test Coverage Reduced:

Resource maintenance in LLM/main/L0_Test-x86_64-Multi-GPU #754: B200 multi-GPU stages are paused to relieve the CI queue backlog (109 running / 459 pending on 2026-10-22). Owner: @sharabeshj-nvda. The CI team decides when to lift it.
Affected stages:
DGX_B200-2_GPUs-PyTorch-1
DGX_B200-4_GPUs-PyTorch-1
DGX_B200-4_GPUs-PyTorch-2

Resolves fmhaKernels.h against NVIDIA#20242 and NVIDIA#20517: both include lists
are kept, and selectKernelAutotuned() takes the selection lock before
the new configurePaddedMlaTile() call. The barrier test follows NVIDIA#20270:
DecoderWarmup no longer carries kv_cache_manager_key, run() warms the
named all-reduce topologies on the model, and the general warmup adds
the MiniMax-M3 MSA indexer prewarm.
