 ## Roadmap
 
+- [RefactorGraph](https://github.com/InfiniTensor/RefactorGraph) is a newly designed AI framework that is set to replace the current main branch.
 - [EinNet](https://github.com/InfiniTensor/InfiniTensor/tree/NNET_e2e) is going to be merged into the main branch.
 - Integration of [PET](https://github.com/thu-pacman/PET), a tensor program optimizer supporting partially equivalent transformations.
 - Supported hardware
   - ✔ NVIDIA GPU
   - ✔ Cambricon MLU
+  - ✔ Kunlunxin XPU
   - ⬜ Ascend NPU
-  - ⬜ Kunlunxin XPU

+# 分布式脚本
+
+#### 1. 运行pytorch模型并生成输入和标准输出，可选择导出onnx
+
+使用 `--export_onnx` 设置导出onnx的目录，默认为当前路径 `./`，不使用这个flag则只进行计算和生成输入输出。
+
+```bash
+python run_pytorch.py --model gpt2  --batch_size 1  --length 1 --export_onnx ./
+```
+
+会在当前目录下生成输入输出文件`test_inputs.npy` 和 `test_results.npy`，目前只支持单一输入输出。
+
+#### 2. 运行InfiniTensor分布式脚本
+
+```bash
+python cuda_launch.py --model "/XXX/XXX.onnx" --nproc_per_node 4 
+```

+## Description
+
+This is a doc to tell you how to run paddle*.py in your machine. If your model run on other machines except Nvidia, you may need to make some change.
+
+## What do we do in paddle*.py files?
+
+1. Train model and evalute model with Cifar10 dataset
+
+2. Export paddle model to onnx model
+
+3. Load onnx model, infer with InfiniTensor and calculate the inference accuracy
+
+## Command
+
+1. Go to `/examples/python` folder 
+
+2. Run the following command
+   
+   1. ```
+      python paddle_resnet.py
+      python paddle_densenet.py
+      python paddle_inception.py
+      ```
+
+## What should I do if I use other device(MLU, XPU, NPU)?
+
+You need to change this code:
+
+```
+paddle.device.set_device("gpu") # Change gpu to mlu, xpu or npu
+```
