Estimated code review effort

🎯 4 (Complex) | ⏱️ ~60 minutes

Areas requiring extra attention:

  • transform/library/fused_moe.py: Extensive pattern matching and graph reconstruction logic for BMM detection; complex weight transformation and normalization across Llama4 and TRT-LLM formats; verify correctness of helper methods (_find_gate_up_bmm, _find_input_and_routing, _find_output_and_routing_flavor) for edge cases.
  • utils/sharding_utils.py: New BmmEPShardingInfo class and sharding insertion logic; verify weight slicing, transposition, and all-reduce semantics align with tensor parallelism requirements; check parameter validation for allreduce strategies.
  • custom_ops/fused_moe/torch_moe.py: Conditional routing application logic; ensure both INPUT-side and OUTPUT-side routing paths produce correct numerics; validate operator registration and fake variant behavior.
  • Integration consistency: Verify that apply_routing_on_input parameter is threaded consistently across custom operators, transform library, and test helpers; check alignment between reference implementations and actual operator behavior.

tensorrt_llm/_torch/auto_deploy/utils/sharding_utils.py (1)

1591-1599: Potential issue with transform list routing.

The _transform_list_dict mapping at line 1598 adds BmmEPShardingInfo after EPShardingInfo at line 1596. Since BmmEPShardingInfo is a subclass of EPShardingInfo, and the add() method uses isinstance() to find the appropriate list, BmmEPShardingInfo instances will match EPShardingInfo first and be routed to ep_transforms instead of stacked_ep_transforms.

Consider reordering so subclasses come before parent classes:

         self._transform_list_dict = {
             WeightShardingInfo: self.weight_sharding_transforms,
             BMMShardingInfo: self.bmm_transforms,
+            BmmEPShardingInfo: self.stacked_ep_transforms,
             EPShardingInfo: self.ep_transforms,
             ParameterUpdateInfo: self.parameter_update_transforms,
-            BmmEPShardingInfo: self.stacked_ep_transforms,

🧹 Nitpick comments (3)
tests/unittest/_torch/auto_deploy/unit/singlegpu/custom_ops/test_ad_moe_op.py (1)

167-169: Clarify test setup: overriding selected_experts discards actual routing.

Line 169 replaces the actual topk routing decisions with all 1s, routing every token to expert 1. Combined with line 168 pre-scaling the input, this creates a specific but potentially confusing test scenario.

Consider adding a comment explaining why this setup is intentional, or use the actual routing from setup_bmm_moe_test for more realistic coverage.

     with torch.inference_mode():
+        # Pre-scale input and force all tokens to expert 1 to test
+        # uniform routing scenario with BMM-based MoE
         x = final_scales * x
         selected_experts = torch.ones_like(selected_experts)
tests/unittest/_torch/helpers.py (1)

131-139: Document the apply_routing_on_input parameter.

The docstring is missing documentation for the apply_routing_on_input parameter. This is important since it has a different default value (True) compared to reference_moe_torch (False).

     """Reference for stacked MoE (torch_moe_bmm) in TRT-LLM format.
 
     Args:
         x: (seq_len, hidden_size)

164-190: Consider simplifying dtype handling and ones_node creation.

Two observations:

  1. Dtype condition (line 168): The condition weight_dtype != torch.float32 casts when weights are NOT float32. However, this doesn't check if the input already matches the weight dtype, potentially adding unnecessary cast operations.

  2. Ones node overhead (lines 186-190): Creating a tensor of ones to prevent the kernel from applying routing adds runtime overhead. Consider adding a kernel flag to skip routing multiplication instead.

-        if weight_dtype is not None and weight_dtype != torch.float32:
+        # Cast to weight dtype only if input dtype differs
+        if weight_dtype is not None and hidden_states.meta.get('tensor_meta', {}).dtype != weight_dtype:
             input_to_scale = graph.call_function(

For the ones_node, this could be a future optimization if profiling shows it's a bottleneck.

Learning: In the CUTLASS MoE kernels (cpp/tensorrt_llm/cutlass_extensions), when `layout_info.fusion` is set to `TmaWarpSpecializedGroupedGemmInput::EpilogueFusion::FINALIZE`, the `router_scales` parameter must be non-null by design. The fused finalize kernel epilogue does not perform nullptr checks and requires valid router scales to function correctly. This is an implicit contract that callers must satisfy when enabling the FINALIZE fusion mode.

Learning: In TensorRT-LLM's CI infrastructure, pytest skip markers (pytest.mark.skip) are properly honored even when test files have __main__ blocks that call test functions directly. The testing system correctly skips tests without requiring modifications to the __main__ block execution pattern.

Learning: In TensorRT-LLM NCCL device allreduce implementation (cpp/tensorrt_llm/thop/allreduceOp.cpp), the goto pattern in runNCCLAllReduceDeviceFusion is intentionally used for future extensibility, allowing multiple switch cases to fallback to the default handler. While not aesthetically ideal, this pattern supports adding more fusion cases later that can reuse the same fallback logic.

🔇 Additional comments (28)
tensorrt_llm/_torch/auto_deploy/config/default.yaml (1)

31-32: LGTM!

The new match_bmm_moe_pattern transform entry is correctly placed in the pattern_matcher stage alongside the existing MoE pattern matchers. The ordering after match_dense_moe_pattern is appropriate.

tensorrt_llm/_torch/auto_deploy/custom_ops/fused_moe/torch_moe.py (4)

29-84: LGTM!

The apply_routing_on_input parameter is well-implemented with clear documentation. The conditional logic correctly handles both routing modes:

  • INPUT-SIDE: silu(input * routing_weight) - routing affects activation
  • OUTPUT-SIDE: silu(input) * routing_weight - routing scales output

The default value False maintains backward compatibility with existing callers.


174-227: LGTM!

The new torch_moe_bmm operator correctly implements BMM-based MoE with stacked TRT-LLM format weights. The implementation:

  • Properly extracts W3 (first half) and W1 (second half) from the fused gate_up tensor
  • Handles dtype conversion for mixed-precision scenarios
  • Delegates to _template_moe with the configurable routing behavior

The documentation clearly specifies the expected weight shapes and routing semantics.


230-240: LGTM!

The fake implementation correctly returns torch.empty_like(x) for shape inference during tracing. The static analysis warnings about unused arguments (ARG001) are expected for fake/stub implementations where the signature must match the real operator.


243-295: LGTM!

The torch_fused_moe implementation correctly follows the SwiGLU computation pattern with TRT-LLM format weights. The docstring updates clearly document the expected weight shapes and format conversions.

tensorrt_llm/_torch/auto_deploy/utils/sharding_utils.py (6)

1096-1153: LGTM!

The _slice_expert_dim function correctly handles both Node and Tensor inputs with proper load hook registration for checkpoint compatibility. The edge case handling for empty module names at line 1127 is appropriate.


1156-1258: LGTM with observation.

The _slice_and_transpose_expert_dim function correctly handles the Llama4 to TRT-LLM format conversion with W1/W3 swapping and transpose operations.

Minor observation: At lines 1204-1206, when swap_gate_up=True for non-parameter nodes, the code logs a warning but continues without actually swapping. This is acceptable given the primary use case is parameter nodes, but worth noting for future maintainers.


1261-1274: LGTM!

The _get_dim0_from_arg helper correctly handles multiple input types (Tensor, get_attr Node, and meta val) with appropriate fallback logic.


1277-1357: LGTM!

The _insert_sharded_moe_bmm function correctly implements EP sharding for BMM-based MoE nodes with stacked weights. The implementation:

  • Properly handles selected_experts and final_scales sharding
  • Applies Llama4 to TRT-LLM format conversion during weight slicing
  • Adds the required all_reduce for result aggregation

The pattern follows the existing _insert_sharded_moe implementation for consistency.


1508-1518: LGTM!

The BmmEPShardingInfo class correctly extends EPShardingInfo with appropriate validation and apply methods for torch_moe_bmm nodes. The unused gm argument in validate is expected for interface consistency with the parent class.


1521-1527: LGTM!

The EP sharding rules are correctly updated to include the mapping for torch_moe_bmm to BmmEPShardingInfo.

tensorrt_llm/_torch/auto_deploy/transform/library/sharding.py (2)

141-143: LGTM!

The executor loop for stacked_ep_transforms follows the established pattern for processing sharding transforms and correctly increments num_matches.


1060-1090: LGTM!

The detect_ep_shard function correctly handles the new torch_moe_bmm op by:

  1. Including it in the MoE op whitelist
  2. Routing it to BmmEPShardingInfo.from_node for proper sharding info creation

The conditional logic cleanly separates BMM-based MoE from other variants while maintaining the existing pattern for other MoE operations.

tests/unittest/_torch/auto_deploy/unit/multigpu/transformations/library/test_ep_sharding.py (1)

162-201: Verify attribute names in SharedConfig class.

The suggested fix changes sharding_config to sharding_transform_container but the attribute naming between stacked_ep_transforms vs ep_transforms needs clarification by cross-referencing the SharedConfig definition and line 132 of the same test file.

tests/unittest/_torch/auto_deploy/unit/singlegpu/custom_ops/test_ad_moe_op.py (2)

65-106: LGTM!

The setup function correctly initializes test data for BMM-based MoE with topk=1 and TRT-LLM formatted stacked weights.


191-204: Verify routing weight application is not doubled.

The input x is pre-scaled by final_scales at line 168, and reference_bmm_moe_torch is called with apply_routing_on_input=True which scales again. Verify that torch_moe_bmm, torch_moe_fused, and trtllm_moe_fused operators all consistently apply or skip routing scaling internally; if they behave differently, the test tolerances and comparison assertions may mask operator divergence.

tests/unittest/_torch/helpers.py (2)

96-121: LGTM!

The apply_routing_on_input parameter addition correctly implements conditional routing—scaling inputs before MLP computation when True, or scaling outputs after when False.


140-170: LGTM!

The implementation correctly handles TRT-LLM weight format with proper slicing and transposition, and the conditional routing logic mirrors reference_moe_torch.

tensorrt_llm/_torch/auto_deploy/transform/library/fused_moe.py (10)

21-92: LGTM!

The function correctly stacks per-expert weights into fused tensors and registers them as parameters. The handling of both gated_mlp and mlp styles is appropriate.


204-257: LGTM!

The unified handling of both standard MoE and Llama4 BMM MoE patterns is clean. The fused_key_counter increment placement after the if/else is correct.


740-760: LGTM!

The config class and transform registration follow the established pattern. The docstring clearly states the topk=1 constraint.


762-827: LGTM!

The _find_gate_up_bmm static method correctly traces back through the BMM MoE pattern: final_bmm ← mul(up, silu(gate)) ← chunk ← first_bmm. The chunk validation (chunk.args[1] != 2) ensures we're matching the expected gate/up split.


829-891: LGTM!

The _find_input_and_routing method correctly validates the topk=1 constraint and traces back to find original input and routing information.


893-944: LGTM!

The _find_output_and_routing_flavor method properly detects both INPUT-SIDE and OUTPUT-SIDE routing patterns by checking for multiplication after the sum operation.


1056-1061: Unused arguments are acceptable for interface compliance.

The cm, factory, and shared_config arguments are required by the BaseTransform._apply interface. The static analysis warnings can be safely ignored.


1070-1076: Consider itertools.pairwise() for Python 3.10+.

Static analysis suggests using itertools.pairwise() for successive pairs. However, since the codebase targets Python 3.8+ per coding guidelines, the current zip() approach is appropriate. The strict= parameter suggestion is also not critical here since both slices come from the same list.


1164-1192: LGTM!

The fusion correctly creates the torch_moe_bmm node with extracted routing information and properly cleans up dead nodes after replacement.


1114-1157: Verify whether the 2-hop heuristic for scatter/sigmoid detection is sufficient for production patterns.

The code allows up to 2 intermediate operations between scatter and sigmoid (specifically designed for to.dtype conversions), but whether this covers all real graph structures in MoE model tracing remains unverified. Review the actual patterns produced during model compilation and check if any exceed this limit.

The performance results of some kernels could be easily affected by the warm/cold L2 cache status. To achieve more precise profiling results, the L2 cache is cleared for every execution by the circular buffer method for better benchmarking during autotuning.

Before this commit, the kv cache manager does the same regardless, which causes a mis-calculation in free memory available to allocate for the KV cache manager, hence causing a crash.

This commit fixes this by letting KV cache manager initialization be aware whether it is doing the dry run or not. If it is a dry run, use the max_tokens setting that is already pre-calculated and filled into kv_cache_config.max_tokens.
