[None][feat] Unify nvfp4 gemm backend #8963

Wong4j · 2025-11-06T06:30:30Z

Summary by CodeRabbit

New Features
- Introduced unified NVFP4 GEMM interface with automatic or manual backend selection (CUTLASS, cuBLASLt, CuteDSL).
Deprecations
- Deprecated existing NVFP4 entry points; users should migrate to the new unified interface.
Breaking Changes
- Linear module constructor now uses nvfp4_backend parameter instead of individual backend flags.
- All original nvfp4_gemm in the repo have been renamed to nvfp4_gemm_cutlass. The new nvfp4_gemm now serves as a unified API and accepts a backend (options: auto, cutlass, cublaslt, cutedsl) as an input parameter. (updated on November 26)
- The input argument alpha in cutedsl has been changed from a host-side float to a device-side tensor to stay consistent with other backends (cutlass, cublaslt) and support the unified interface. (updated on November 26)
Tests
- Added comprehensive test coverage for unified backend selection and tactic handling.

Description

This PR introduces a unified NVFP4 GEMM interface that consolidates multiple backend implementations (CUTLASS, cuBLASLt, and CuteDSL) into a single, easy-to-use API with automatic performance optimization.

Introduced torch.ops.trtllm.nvfp4_gemm_unified with a backend parameter supporting:

"auto" (default): Automatically profiles all available backends and selects the best one
"cutlass": Force CUTLASS backend
"cublaslt": Force cuBLASLt backend
"cutedsl": Force CuteDSL backend

Example:

output = torch.ops.trtllm.nvfp4_gemm_unified(
    act_fp4, weight, act_sf, weight_scale, alpha, 
    output_dtype, backend='auto'
)

📝 Walkthrough

Walkthrough

The changes consolidate multiple NVFP4 GEMM backends (CUTLASS, cuBLASLt, CuteDSL) into a unified entry point nvfp4_gemm_unified with automatic or explicit backend selection. Existing backend-specific functions and Boolean flags are deprecated with warnings, while the Linear module is refactored to replace multiple Boolean parameters with a single string-based nvfp4_backend parameter for runtime backend selection.

Changes

Cohort / File(s)	Summary
Deprecation notices `tensorrt_llm/_torch/custom_ops/cute_dsl_custom_ops.py`, `tensorrt_llm/_torch/custom_ops/torch_custom_ops.py`	Added deprecation docstrings and `logger.warning_once` to `cute_dsl_nvfp4_gemm_blackwell`, `nvfp4_gemm_cublaslt`, and `nvfp4_gemm` functions, directing users to the new `nvfp4_gemm_unified` entry point.
Unified NVFP4 interface `tensorrt_llm/_torch/custom_ops/torch_custom_ops.py`	Introduced new public function `nvfp4_gemm_unified` with auto/explicit backend selection (CUTLASS, cuBLASLt, CuteDSL). Added `CuteDSLNVFP4Wrapper` class to normalize CuteDSL backend interface. Added conditional imports and capability checks (`IS_CUBLASLT_AVAILABLE`, `IS_CUTLASS_DSL_AVAILABLE`).
Linear module refactoring `tensorrt_llm/_torch/modules/linear.py`	Replaced Boolean backend flags (`use_cute_dsl_nvfp4_blockscaling_mm`, `use_cublaslt_nvfp4_blockscaling_mm`) with single string parameter `nvfp4_backend` (default `"auto"`) in Linear class constructor. Consolidated backend selection branching logic to use unified `nvfp4_gemm_unified` call. Updated `NVFP4LinearMethod` to propagate `nvfp4_backend` parameter.
Test suite expansions `tests/unittest/_torch/thop/parallel/test_fp4_linear.py`	Updated existing tests to use `nvfp4_backend='cutedsl'` instead of Boolean flags. Added comprehensive test suite for `nvfp4_gemm_unified` including auto-backend selection, explicit backend testing (CUTLASS, cuBLASLt, CuteDSL), tactic discovery/replay, and autotuning validation. Included hardware capability and SM version gates for Blackwell-specific tests.

Estimated code review effort

🎯 4 (Complex) | ⏱️ ~45 minutes

New public API surface: nvfp4_gemm_unified function and CuteDSLNVFP4Wrapper class require careful validation of backend selection logic, input validation, and error handling.
Refactored module interface: Linear class constructor signature changed from multiple Boolean flags to a string parameter; verify all initialization paths, weight loading, and backward compatibility considerations.
Deprecation propagation: Ensure deprecation warnings are correctly routed and logged without disrupting functionality in existing code paths.
Multi-backend routing logic: The backend selection and runner initialization in nvfp4_gemm_unified and wrapper class involves conditional imports and runtime capability checks that need verification across different hardware/software configurations.
Test coverage heterogeneity: New tests span multiple backend implementations, autotuning flows, and hardware gates; each test variant may require separate reasoning.

Wong4j · 2025-11-13T02:22:22Z

In single tests, multiple backends may be tested, which can lead to the following situation. For example:

The first ut, using “auto”:

runners = [
    FP4GemmRunner(...),           # idx=0  (CUTLASS)
    CublasLtFP4GemmRunner(...),   # idx=1  (cuBLASLt)
    CuteDSLNVFP4Wrapper(...),     # idx=2  (CuteDSL)
]

The second ut, forcing “cublaslt”:

runners = [
    CublasLtFP4GemmRunner(...),   # idx=0  (only this one!)
]

In this case, the cached idx becomes incorrect, leading to an IndexError: list index out of range.
So I modified the autotuner.py code, but I’m not sure if this will cause any side effects.
Could you please take a look? @rosenrodt

Just put some general ideas about how to define a nested tuning op. This might be clearer and more expandable.

This is critical and very helpful change for DS R1 performance - we probably need to verify the performance before merging it to avoid perf regression.

@kaiyux Doesn't DS-R1 NVFP4 checkpoint actually use very few FP4 GEMMs? I see most of the GEMMs in the up/down projection is still in BF16. And while MoE is indeed NVFP4, this PR touches only the dense GEMMs, not MoE grouped GEMMs

We're currently working on moving more dense gemms to nvfp4, it will helpfully be landed soon. (that should not block this PR though)

hyukn · 2025-11-13T16:59:27Z

To simplify the nested tuning process, we want :

The inner op is not forced to have forward and get_valid_tactics to be implemented (whether it is a tunable one or not).
The interface of the inner op is not required to be the same as any other candidate op. (wrapper is not necessary).

This commit might be helpful to illustrate the idea: hyukn@b5d3b4c

I just took minutes to write the draft commit based on @Wong4j 's original changes, but without any local validation. Maybe @Wong4j can try this idea to see if it achieves the same tuning purpose as the original code. Truly appreciate.

To simplify the nested tuning process, we want :

The inner op is not forced to have forward and get_valid_tactics to be implemented (whether it is a tunable one or not).

The interface of the inner op is not required to be the same as any other candidate op. (wrapper is not necessary).

Sure, I will try it.

hyukn · 2025-11-14T03:15:31Z

Sure, I will try it.
Thanks a lot for the effort.

I have just pushed another commit to clean the code and make UT work. Because this is the first practical nested tuning process, it is a good opportunity to explore if we can do things in a tidy and efficient way. Some concerns:

AutoTuner will do redundant profiling generation, which introduces a lot of host overhead even if the inputs are already in the profiling cache. This will destroy the outer tuning. Thus, I did some minor changes to the AutoTuner to eliminate this unacceptable
overhead.
When doing nested tuning, capture-replay mechanisms will encounter some issues. I guess it might be the status of the counter that is shared among all the ops, which will be incorrectly updated for the nested tuning process. Therefore, I just disabled that part in the UT for now. Maybe we can do some extra work to make this correct later. cc @rosenrodt
I suggest @Wong4j observing the final profiling cache status. It should contain all the results for each low-level NVFP4 gemm tuning result, followed by the unified op tuning result.

Hope this will help.

hyukn · 2025-11-21T03:31:11Z

Hi @Wong4j. Thanks a lot for the effort!
I just moved the common code changes in AutoTuner to a standalone PR #9348 because it might be required by other tunable op as well.

How does the CuteDSL and cuda_core DSL supports to_userbuffers=True? I do not see related change. to_userbuffers=1 means the op must writes to a UB buffer. Or the following allreduce would fail.

cuda_core:

TensorRT-LLM/cpp/tensorrt_llm/thop/cudaNvfp4MM.cpp

Lines 120 to 122 in 9d2df04

    
           if (to_userbuffers) 
        
           { 
        
               out = torch_ext::create_userbuffers_tensor(output_size, out_dtype_).first;

cubalslt:

TensorRT-LLM/cpp/tensorrt_llm/thop/cublasFp4ScaledMM.cpp

Lines 189 to 191 in 9d2df04

    
           if (to_userbuffers) 
        
           { 
        
               out = torch_ext::create_userbuffers_tensor(output_size, mOutputDtype).first;

cutlass:

TensorRT-LLM/cpp/tensorrt_llm/thop/fp4Gemm.cpp

Lines 198 to 200 in 9d2df04

    
               out = torch_ext::create_userbuffers_tensor(out_shape, out_dtype.value()).first; 
        
           } 
        
           else

For CuteDSL, I add to_userbuffers here:
