This directory contains benchmarking tools for MoE (Mixture of Experts) kernels.
### Tuning Tool
### Overview
- `tuning_fused_moe_triton.py`: A tool for tuning the `fused_moe_triton` kernel. Adapted from [vllm's benchmark_moe.py](https://github.com/vllm-project/vllm/blob/main/benchmarks/kernels/benchmark_moe.py), with added support for various model architectures.
The tuning tools support both **Tensor Parallelism (TP)** and **Expert Parallelism (EP)** modes:
Example usage:
- **TP Mode**: Traditional tensor parallelism where intermediate layers are sharded across GPUs
- **EP Mode**: Expert parallelism where experts are distributed across GPUs. Can be combined with TP mode (e.g., `--tp-size 8 --ep-size 2`)
- **MLLM Support**: Multi-modal Large Language Models with text encoders (e.g., Llama4, Qwen3VL)
### Tuning Tools
#### 1. `tuning_fused_moe_triton.py`
A unified tool for tuning the `fused_moe_triton` kernel. Adapted from [vllm's benchmark_moe.py](https://github.com/vllm-project/vllm/blob/main/benchmarks/kernels/benchmark_moe.py), with support for EP mode and various model architectures.
#### 2. `tuning_fused_moe_triton_sep.py`
A specialized tool for separate kernel tuning, optimizing the first and second MoE kernels independently with TMA (Tensor Memory Accelerator) support.
### Usage Examples
#### Basic TP Mode Tuning
```bash
# Tune Mixtral-8x7B with default settings
# Tune Mixtral-8x7B with default TP settings
python benchmark/kernels/fused_moe_triton/tuning_fused_moe_triton.py \
--model mistralai/Mixtral-8x7B-Instruct-v0.1 \
--tune
......@@ -20,29 +34,149 @@ python benchmark/kernels/fused_moe_triton/tuning_fused_moe_triton.py \

--dtype fp8_w8a8 \
--tune
```
# Tune DeepSeek-V3 with FP8 and TP=8
#### EP Mode Tuning (Expert Parallelism)
**Note**: EP mode can be used alone or combined with TP mode. When using both, ensure `tp_size` is divisible by `ep_size`.
```bash
# Tune Mixtral-8x7B with EP=2 only
python benchmark/kernels/fused_moe_triton/tuning_fused_moe_triton.py \
--model mistralai/Mixtral-8x7B-Instruct-v0.1 \

```
#### MLLM Model Tuning (Multi-modal)
```bash
python benchmark/kernels/fused_moe_triton/tuning_fused_moe_triton.py \
--model Qwen/Qwen3-VL-30B-A3B-Instruct \
--tp-size 2 \
--tune
```
#### Separate Kernel Tuning with `tuning_fused_moe_triton_sep.py`
This tool requires pre-generated topk_ids files and supports both TP and EP modes:
Edit the code file (such as srt/models/deepseek_v2.py) in the Python site package and add the logic for saving topk_ids:
```python
# import get_tensor_model_parallel_rank
# DeepseekV2MoE::forward_normal
if hidden_states.shape[0] >= 4096 and get_tensor_model_parallel_rank() == 0:
topk_ids_dir = xxxx
if not hasattr(self, "save_idx"):
self.save_idx = 0
if self.save_idx <= 1:
torch.save(topk_output.topk_ids, f"{topk_ids_dir}/topk_ids_layer{self.layer_id}_idx{self.save_idx}.pt")
self.save_idx += 1
```
Launch sglang server and send request using `benchmark/kernels/fused_moe_triton/tuning_client.py`
```bash
python benchmark/kernels/fused_moe_triton/tuning_client.py --port 8000
```
```bash

#### Advanced Options
```bash

python benchmark/kernels/fused_moe_triton/tuning_fused_moe_triton.py \

--model mistralai/Mixtral-8x7B-Instruct-v0.1 \
--batch-size 2048 \
--tune
```
After tuning, a configuration file (e.g., `E=64,N=640,device_name=NVIDIA_GeForce_RTX_4090,dtype=fp8_w8a8.json`) will be generated in the current directory. You can move this file to `sglang/srt/layers/fused_moe_triton/configs/triton_version` dir to use it in `sglang`.
### Configuration Files
After tuning, configuration files will be generated:
- **Standard tuning**: `E=64,N=640,device_name=NVIDIA_GeForce_RTX_4090,dtype=fp8_w8a8.json`
- **Separate kernel tuning**: Two files for up/down kernels with TMA optimization flags
Move these files to `sglang/srt/layers/fused_moe_triton/configs/triton_version/` directory to use them in SGLang.
### Supported Models
- **Mixtral**: mistralai/Mixtral-8x7B-Instruct-v0.1, mixtral-8x22b
- **Qwen**: Qwen2-57B, Qwen3-235B, Qwen3VL (MLLM)

### Performance Comparison Tool

- `benchmark_torch_compile_fused_moe.py`: A tool for benchmarking the performance of the fused MoE kernel with `torch.compile` and original fused MoE kernel.
Usage is the same as `benchmark_vllm_vs_sglang_fused_moe_triton.py`, note that `torch.compile` does not support `fp8_w8a8` and `int8_w8a8` fused_moe_kernel.
Usage is similar to `benchmark_vllm_vs_sglang_fused_moe_triton.py`, note that `torch.compile` does not support `fp8_w8a8` and `int8_w8a8` fused_moe_kernel. Both tools now support EP mode with `--ep-size` parameter.
