 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 \

     --tune
@@ -20,29 +34,149 @@ python benchmark/kernels/fused_moe_triton/tuning_fused_moe_triton.py \

+    --tp-size 8 \
     --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 \

+    --tp-size 8 \
+    --ep-size 4 \
+    --dtype fp8_w8a8 \
+    --tune
+```
+
+#### 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`

-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`.
