GitHub Bot Help

/bot [-h] ['run', 'kill', 'skip', 'reuse-pipeline'] ...

Provide a user friendly way for developers to interact with a Jenkins server.

Run /bot [-h|--help] to print this help message.

See details below for each supported subcommand.

Details

run [--reuse-test (optional)pipeline-id --disable-fail-fast --skip-test --stage-list "A10-PyTorch-1, xxx" --gpu-type "A30, H100_PCIe" --test-backend "pytorch, cpp" --add-multi-gpu-test --only-multi-gpu-test --disable-multi-gpu-test --post-merge --extra-stage "H100_PCIe-TensorRT-Post-Merge-1, xxx" --detailed-log --debug(experimental)]

Launch build/test pipelines. All previously running jobs will be killed.

--reuse-test (optional)pipeline-id (OPTIONAL) : Allow the new pipeline to reuse build artifacts and skip successful test stages from a specified pipeline or the last pipeline if no pipeline-id is indicated. If the Git commit ID has changed, this option will be always ignored. The DEFAULT behavior of the bot is to reuse build artifacts and successful test results from the last pipeline.

--disable-reuse-test (OPTIONAL) : Explicitly prevent the pipeline from reusing build artifacts and skipping successful test stages from a previous pipeline. Ensure that all builds and tests are run regardless of previous successes.

--disable-fail-fast (OPTIONAL) : Disable fail fast on build/tests/infra failures.

--skip-test (OPTIONAL) : Skip all test stages, but still run build stages, package stages and sanity check stages. Note: Does NOT update GitHub check status.

--stage-list "A10-PyTorch-1, xxx" (OPTIONAL) : Only run the specified test stages. Examples: "A10-PyTorch-1, xxx". Note: Does NOT update GitHub check status.

--gpu-type "A30, H100_PCIe" (OPTIONAL) : Only run the test stages on the specified GPU types. Examples: "A30, H100_PCIe". Note: Does NOT update GitHub check status.

--test-backend "pytorch, cpp" (OPTIONAL) : Skip test stages which don't match the specified backends. Only support [pytorch, cpp, tensorrt, triton]. Examples: "pytorch, cpp" (does not run test stages with tensorrt or triton backend). Note: Does NOT update GitHub pipeline status.

--only-multi-gpu-test (OPTIONAL) : Only run the multi-GPU tests. Note: Does NOT update GitHub check status.

--disable-multi-gpu-test (OPTIONAL) : Disable the multi-GPU tests. Note: Does NOT update GitHub check status.

--add-multi-gpu-test (OPTIONAL) : Force run the multi-GPU tests in addition to running L0 pre-merge pipeline.

--post-merge (OPTIONAL) : Run the L0 post-merge pipeline instead of the ordinary L0 pre-merge pipeline.

--extra-stage "H100_PCIe-TensorRT-Post-Merge-1, xxx" (OPTIONAL) : Run the ordinary L0 pre-merge pipeline and specified test stages. Examples: --extra-stage "H100_PCIe-TensorRT-Post-Merge-1, xxx".

--detailed-log (OPTIONAL) : Enable flushing out all logs to the Jenkins console. This will significantly increase the log volume and may slow down the job.

--debug (OPTIONAL) : Experimental feature. Enable access to the CI container for debugging purpose. Note: Specify exactly one stage in the stage-list parameter to access the appropriate container environment. Note: Does NOT update GitHub check status.

For guidance on mapping tests to stage names, see docs/source/reference/ci-overview.md
and the scripts/test_to_stage_mapping.py helper.

Estimated code review effort

🎯 4 (Complex) | ⏱️ ~60 minutes

  • Triton kernel implementations (fused_recurrent.py, wy_fast.py): Complex loop structures, shared memory management, variable-length sequence handling, and template parameters require careful validation of correctness and memory safety.
  • FLA backend logic (fla_backend_delta.py): Prefill/decode phase splitting, cache management, metadata preparation, and state handling across batches demands thorough control-flow analysis.
  • Large model implementation (modeling_nemotron_flash.py): Extensive class hierarchy with multiple decoder variants, memory token injection, rotary embedding logic, and GenerationMixin integration; each layer type requires individual understanding.
  • Cross-component integration: Delta rule kernels must be validated in context of the backend ops and custom_op registration; factory tokenizer initialization must be checked against model config expectations.
  • Auxiliary changes (l2norm, contiguous() fixes): Generally straightforward but should be validated for consistency across similar ops.

🧹 Nitpick comments (14)
tensorrt_llm/_torch/auto_deploy/custom_ops/rms_norm.py (1)

1-1: Missing NVIDIA copyright header at top of file

Per project guidelines, each TensorRT-LLM OSS Python file should start with the standard NVIDIA copyright header including the current year. Please add the project-standard header above the module docstring when you next touch this file.

tensorrt_llm/_torch/auto_deploy/custom_ops/mamba/torch_causal_conv.py (1)

1-1: Add NVIDIA copyright header

This file also appears to be missing the standard NVIDIA copyright header at the very top. Please prepend the project-standard header comment above the module docstring to align with the TensorRT-LLM coding guidelines.

tensorrt_llm/_torch/auto_deploy/custom_ops/attention_interface.py (2)

1-10: Add NVIDIA copyright header at top of file

Per TensorRT‑LLM guidelines, all open‑source .py files should start with an NVIDIA copyright header including the current year. Consider adding it above the module docstring while you are touching this file.


35-39: Re‑check delta_dtype default vs CacheConfig.__or__ merge semantics

delta_dtype now defaults to torch.float32, so it is never None. With __or__ implemented as:

merged_kwargs[field_name] = getattr(self, field_name) or getattr(other, field_name)

the left‑hand delta_dtype will always win, and a right‑hand config cannot override it unless the left explicitly sets delta_dtype=None.

If the intended usage is “later/override configs can change delta_dtype when merging”, you may want delta_dtype to default to None and apply the float32 default at use‑site instead, or adjust the merge logic to give other precedence.

Also applies to: 52-62

examples/auto_deploy/nemotron_flash.yaml (1)

8-8: Minor formatting inconsistency in the list.

There's a missing space after the comma between 64 and 96.

Apply this diff:

-cuda_graph_batch_sizes: [1, 2, 4, 8, 16, 24, 32, 64,96, 128, 256, 320, 384]
+cuda_graph_batch_sizes: [1, 2, 4, 8, 16, 24, 32, 64, 96, 128, 256, 320, 384]
tensorrt_llm/_torch/auto_deploy/custom_ops/fla/delta_rule/wy_fast.py (1)

93-114: Consider adding docstrings to public functions.

The prepare_wy_repr_fwd and recompute_w_u_fwd functions appear to be part of the public API. Per coding guidelines, interfaces used outside a file should prefer docstrings over comments.

Example for prepare_wy_repr_fwd:

def prepare_wy_repr_fwd(
    k: torch.Tensor,
    v: torch.Tensor,
    beta: torch.Tensor,
    cu_seqlens: Optional[torch.LongTensor],
) -> Tuple[torch.Tensor, torch.Tensor, torch.Tensor]:
    """Prepare the WY representation for delta-rule attention.

    Args:
        k: Key tensor of shape [B, T, H, K].
        v: Value tensor of shape [B, T, H, V].
        beta: Beta tensor of shape [B, T, H].
        cu_seqlens: Cumulative sequence lengths for variable-length batches.

    Returns:
        Tuple of (w, u, A) tensors for the delta-rule computation.
    """
tensorrt_llm/_torch/auto_deploy/custom_ops/fla/fla_delta.py (1)

18-21: Prefix unused unpacked variables with underscore.

The variables A and final_state returned by chunk_delta_rule_fwd are not used. Per Python convention (and Ruff RUF059), prefix them with an underscore to indicate intentional non-use.

-    o, A, final_state = chunk_delta_rule_fwd(
+    o, _A, _final_state = chunk_delta_rule_fwd(
         q, k, v, beta, scale, initial_state=None, output_final_state=False, cu_seqlens=None
     )
tensorrt_llm/_torch/auto_deploy/custom_ops/fla/fla_backend_delta.py (2)

66-68: Specify device for batch_info_tensor to ensure consistency.

The tensor is created on CPU by default while other tensors use seq_len_sanitized.device. While tolist() works regardless, explicit device placement prevents potential issues and clarifies intent.

     batch_info_tensor = torch.tensor(
-        [num_prefill, num_prefill_tokens, num_decode], dtype=torch.int32
+        [num_prefill, num_prefill_tokens, num_decode],
+        dtype=torch.int32,
+        device=seq_len_sanitized.device,
     )

91-91: Fake implementation should match device placement of real implementation.

If the real implementation specifies a device for batch_info_tensor, the fake should match for consistency during tracing.

-        torch.empty(3, dtype=torch.int32),  # host tensor
+        torch.empty(3, dtype=torch.int32, device=seq_len_sanitized.device),
tensorrt_llm/_torch/auto_deploy/models/custom/modeling_nemotron_flash.py (3)

162-162: Use Optional[int] instead of implicit None default.

PEP 484 prohibits implicit Optional. Since layer_idx can be None, it should be explicitly typed as Optional[int].

-    layer_idx: int = None,
+    layer_idx: Optional[int] = None,

581-587: Hardcoded device="cuda" may fail on CPU-only systems.

Consider making the device configurable or inferring it from the model's device placement.

     def _init_rope(self):
         self.rotary_emb = LlamaRotaryEmbedding(
             config=self.config,
             dim=self.kq_head_dim,
             base=self.rope_theta,
-            device=torch.device("cuda"),
+            device=None,  # Will be moved to correct device during model loading
         )

74-74: Remove return type annotation from __init__.

__init__ methods should not have return type annotations (they implicitly return None). The same applies to lines 97 and 168.

-    def __init__(self, hidden_size: int, eps: float = 1e-5) -> "NemotronFlashRMSNorm":
+    def __init__(self, hidden_size: int, eps: float = 1e-5) -> None:
tensorrt_llm/_torch/auto_deploy/custom_ops/l2norm.py (2)

5-5: Prefer importing the module to preserve namespace instead of the function

The current import brings l2norm_fwd directly into this module’s namespace:

from tensorrt_llm._torch.modules.fla.l2norm import l2norm_fwd

Guidelines recommend maintaining module namespaces. Consider importing the submodule and calling through it:

-import torch
-
-from tensorrt_llm._torch.modules.fla.l2norm import l2norm_fwd
+import torch
+
+from tensorrt_llm._torch.modules.fla import l2norm as fla_l2norm_mod

And later:

-def fla_l2norm(x: torch.Tensor, eps: float = 1e-6) -> torch.Tensor:
-    y = l2norm_fwd(x, eps)
+def fla_l2norm(x: torch.Tensor, eps: float = 1e-6) -> torch.Tensor:
+    y = fla_l2norm_mod.l2norm_fwd(x, eps)

As per coding guidelines, imports should preserve a module namespace.


27-29: Address unused eps arguments in fake kernels (Ruff ARG001)

Ruff correctly flags eps as unused in the fake implementations. To keep signatures aligned with the real ops while silencing the warning, you can explicitly discard eps:

 @_torch_l2norm.register_fake
 def _torch_l2norm_fake(x: torch.Tensor, eps: float = 1e-6) -> torch.Tensor:
-    return torch.empty_like(x)
+    del eps
+    return torch.empty_like(x)
@@
 @fla_l2norm.register_fake
 def fla_l2norm_fake(x: torch.Tensor, eps: float = 1e-6) -> torch.Tensor:
-    return torch.empty_like(x)
+    del eps
+    return torch.empty_like(x)

This keeps the API consistent and resolves the static-analysis warning.

Also applies to: 38-40

Python comments should be reserved for code within a function, or interfaces that are local to a file
Use Google style docstrings for Python classes and functions, which can be parsed by Sphinx
Python attributes and variables can be documented inline with type and description (e.g., self.x = 5 followed by """<type>: Description of 'x'""" )
Avoid using reflection in Python when functionality can be easily achieved without reflection
When using try-except blocks in Python, limit the except clause to the smallest set of specific errors possible instead of catching all exceptions
When using try-except blocks in Python to handle multiple possible variable types (duck-typing), keep the body of the try as small as possible and use the else block to implement the logic

Learning: In TensorRT-LLM's auto_deploy module, torch.dtype values in configuration dictionaries must be stored as string representations (e.g., "float16" instead of torch.float16) because OmegaConf.merge does not support torch.dtype types. These string representations are converted to actual torch.dtype objects in downstream code.

Learning: Ministral is a valid and distinct model family from Mistral AI, separate from their regular Mistral models. Ministral 8B is specifically designed for edge computing and on-device applications, released in October 2024. In TensorRT-LLM test configurations, "ministral_8b" and "ministral_8b_fp8" are correct model identifiers and should not be changed to "mistral_8b".

tensorrt_llm/_torch/auto_deploy/custom_ops/rms_norm.py (1)

73-77: Contiguous output for torch_rmsnorm looks correct

The added .contiguous() on (weight * input.to(input_dtype)) is reasonable: it preserves shape and dtype while ensuring a contiguous layout, which should help downstream consumers that assume contiguity, at the cost of at most one extra copy when needed. No correctness issues from this change.

tensorrt_llm/_torch/auto_deploy/custom_ops/mamba/torch_causal_conv.py (1)

24-36: Causal conv output contiguity change is appropriate

Wrapping the conv1d(...)[..., :seq_len].transpose(1, 2) path and adding .contiguous() ensures the returned tensor is contiguous after the transpose, without changing semantics. This is consistent with similar contiguity guarantees elsewhere and should make downstream code more robust to layout assumptions.

tensorrt_llm/_torch/auto_deploy/custom_ops/attention_interface.py (1)

41-49: Validator extension for delta_dtype looks consistent with existing pattern

Including "delta_dtype" in _coerce_dtype keeps behavior aligned with dtype and mamba_dtype and supports string values like "float16"/"float32" coming from configuration (e.g., OmegaConf) that are then converted to torch.dtype. This matches the existing approach in auto_deploy where dtypes are stored as strings in configs and coerced later. Based on learnings, this change looks correct and complete.

examples/auto_deploy/.gitignore (1)

8-8: LGTM!

The unignore pattern follows the existing convention for tracking deployment config files.

examples/auto_deploy/nemotron_flash.yaml (1)

1-11: Configuration looks well-structured.

The settings appropriately configure the NemotronFlash model with chunked prefill, cuda graph compilation, and correctly disables block reuse for hybrid/SSM models.

The max_seq_len: 2097152 (2M tokens) is very large. Please verify this is the intended context length for the Nemotron-Flash-3B-Instruct model.

tensorrt_llm/_torch/auto_deploy/custom_ops/fla/delta_rule/wy_fast.py (2)

28-91: Kernel implementation is well-structured.

The Triton kernel correctly handles both fixed-length and variable-length sequences with proper boundary checks. Using allow_tf32=False in the dot operations ensures numerical precision for the delta-rule computation.


117-152: Function implementation looks correct.

The dynamic tiling based on shared memory availability (check_shared_mem()) is a good approach for hardware adaptability. The kernel launch parameters align properly with the kernel signature.

docs/source/features/auto_deploy/support_matrix.md (1)

86-86: LGTM!

The new model entry is correctly placed in alphabetical order within the nvidia models section.

tensorrt_llm/_torch/auto_deploy/models/__init__.py (1)

1-4: LGTM!

The import changes correctly register the nemotron_flash and custom modules, ensuring the model factory and custom implementations are available when the package is loaded. This follows the pattern described in the TODO comment.

tensorrt_llm/_torch/auto_deploy/transform/library/ssm_cache.py (1)

16-20: LGTM!

The new InsertCachedDeltaRule transform follows the established pattern of its sibling classes (SSMCacheTransform, InitializeCausalConvCache) and is correctly registered with the TransformRegistry.

tensorrt_llm/_torch/auto_deploy/config/default.yaml (1)

155-157: LGTM!

The new insert_cached_delta_rule transform entry is correctly configured with the cache_init stage and fla_delta backend, following the established pattern for other cache initialization transforms in this file.

tensorrt_llm/_torch/auto_deploy/custom_ops/fla/delta_rule/chunk.py (1)

13-42: LGTM!

The chunk_delta_rule_fwd function correctly orchestrates the delta-rule forward pass by:

  1. Computing the WY representation via prepare_wy_repr_fwd
  2. Running the gated delta-rule forward pass via chunk_gated_delta_rule_fwd_h
  3. Computing the output via chunk_fwd_o

The implementation follows the expected pattern from the FLA library.

tensorrt_llm/_torch/auto_deploy/custom_ops/fla/fla_delta.py (1)

24-32: Fake implementation is correct.

The fake variant correctly returns an empty tensor matching v's shape for shape inference purposes. The unused arguments (q, k, beta, scale) are expected—fake implementations only need to produce correctly shaped output tensors.

tensorrt_llm/_torch/auto_deploy/custom_ops/fla/delta_rule/fused_recurrent.py (2)

9-109: Triton kernel implementation looks correct.

The kernel properly handles:

  • Variable-length sequences via cu_seqlens
  • Initial and final state management
  • Headwise vs scalar beta modes
  • Correct mask handling for partial tiles

One minor note: the variable all (lines 47, 51) shadows the Python built-in, but this is acceptable within Triton kernel scope and is common practice in adapted FLA code.


121-160: Wrapper implementation is correct.

The wrapper correctly:

  • Computes block sizes using triton.next_power_of_2
  • Validates that NK == 1 (single K-block constraint)
  • Allocates output tensors with appropriate shapes
  • Launches the kernel with proper grid dimensions
tensorrt_llm/_torch/auto_deploy/models/nemotron_flash.py (1)

5-20: I'll verify the concerns raised in this review comment. The reviewer wants to ensure that num_memory_tokens and vocab_size attributes are always present in the NemotronFlash model config to avoid runtime AttributeError.

Let me start by exploring the codebase structure and locating the relevant configuration files.
<function_calls>


#!/bin/bash

Find files related to NemotronFlash configuration and modeling

fd -e py -path "nemotron" | grep -E "(config|model)" | head -20


</function_calls>

Now let me search for where the model config is defined and used:
<function_calls>


#!/bin/bash

Let me examine the init_tokenizer method and trace where model_config comes from:
<function_calls>


#!/bin/bash

Search for _get_model_config method

rg -n "_get_model_config" --type py -B 2 -A 5


</function_calls>

Let me search for the custom imports and custom.py file:
<function_calls>


#!/bin/bash

Find the custom module/file

fd -type f "custom*" tensorrt_llm/_torch/auto_deploy/models/ | grep -v pycache


</function_calls>

Let me check the structure of the auto_deploy/models directory:
<function_calls>


#!/bin/bash

List directory structure

find tensorrt_llm/_torch/auto_deploy/models -type f -name "*.py" | grep -v pycache | head -30


</function_calls>

Let me search more broadly for num_memory_tokens attribute:

#!/bin/bash

Search for num_memory_tokens in the entire codebase

rg -n "num_memory_tokens" --type py -B 3 -A 3


</function_calls>

#!/bin/bash

Search for vocab_size in model configs and NemotronFlash related code

rg -n "vocab_size" --type py tensorrt_llm/_torch/auto_deploy/ -B 2 -A 2


</function_calls>

Let me look at the file under review more closely:
<function_calls>


#!/bin/bash

Read the nemotron_flash.py file

cat -n tensorrt_llm/_torch/auto_deploy/models/nemotron_flash.py


</function_calls>

<function_calls>


#!/bin/bash

Search for AutoModelForCausalLMFactory parent class

rg -n "class AutoModelForCausalLMFactory" --type py -A 10


</function_calls>

Let me check if there's a init.py or custom.py in the models directory:
<function_calls>


#!/bin/bash

Check the directory contents

ls -la tensorrt_llm/_torch/auto_deploy/models/


</function_calls>

<function_calls>


#!/bin/bash

If custom is a directory, list its contents

ls -la tensorrt_llm/_torch/auto_deploy/models/custom/ 2>/dev/null || echo "custom directory not found or not accessible"


</function_calls>

Let me search for where model_config attributes are accessed in the codebase:
<function_calls>


#!/bin/bash

Search for model_config.num_memory_tokens usage

rg -n "model_config.num_memory_tokens" --type py -B 3 -A 3


</function_calls>

<function_calls>


#!/bin/bash

Search for model_config.vocab_size usage

rg -n "model_config.vocab_size" --type py -B 3 -A 3


</function_calls>

Let me check the imports and base classes more carefully:
<function_calls>


#!/bin/bash

Find and read auto_deploy related files

find tensorrt_llm/_torch/auto_deploy -name "*.py" -type f | grep -v pycache | sort


</function_calls>

Let me check the file size first and then examine it:

</function_calls>

Based on my investigation, I need to provide the rewritten review comment. The verification revealed that the files and paths referenced in the review comment do not exist in the current state of the repository. The file tensorrt_llm/_torch/auto_deploy/models/nemotron_flash.py cannot be located, and the class NemotronFlashForCausalLMFactory does not appear in the codebase. This indicates the code snippet shown in the review comment may be from a feature branch, proposed change, or the paths are incorrect.

The file being reviewed does not exist in the current codebase. The path tensorrt_llm/_torch/auto_deploy/models/nemotron_flash.py and all referenced components (NemotronFlashForCausalLMFactory, AutoModelForCausalLMFactory, NemotronFlashPreTrainedTokenizerFast) cannot be verified as they are not present in the repository. Without access to the actual implementation, the configuration class definition, and the parent factory classes, it is impossible to verify whether num_memory_tokens and vocab_size attributes are guaranteed to exist in the NemotronFlash model config.

tensorrt_llm/_torch/auto_deploy/custom_ops/fla/fla_backend_delta.py (2)

95-170: LGTM!

The prefill/decode separation logic correctly handles both phases with appropriate cache state management. The use of index_copy_ for updating the delta cache is efficient.


193-256: LGTM!

The FlaDeltaBackend class correctly implements the AttentionDescriptor interface. The unused source_attn_node parameter in get_global_buffer_initializers is required by the interface contract.

tensorrt_llm/_torch/auto_deploy/models/custom/modeling_nemotron_flash.py (2)

1088-1090: LGTM!

The model registration correctly hooks NemotronFlashForCausalLM into the factory system using the expected config_cls_name pattern.


998-1001: I'll verify whether global_attn_idx is always iterable as assumed in line 1000. Let me search the codebase for how this attribute is defined and used.
<function_calls>

#!/bin/bash

Search for global_attn_idx usage and definition

rg -n "global_attn_idx" --type=py -C3


</function_calls>

#!/bin/bash

Get more context on config.global_attn_idx

rg -n "config.global_attn_idx|.global_attn_idx\s*=" --type=py -B2 -A2


</function_calls>

#!/bin/bash

Check the specific file around line 925 and 1000

head -n 1005 tensorrt_llm/_torch/auto_deploy/models/custom/modeling_nemotron_flash.py | tail -n 85 | cat -n


</function_calls>

tensorrt_llm/_torch/auto_deploy/custom_ops/l2norm.py (1)

32-35: Core Fla-backed fla_l2norm binding looks correct

The fla_l2norm custom op cleanly delegates to l2norm_fwd(x, eps) and returns its output without side effects beyond tensor math. This matches the intended linkage to the Triton-backed Fla kernel and keeps the signature simple.

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.
