+## 1. OpenCL 环境准备
+
+### 1.1 查看 OpenCL 设备
+
+```bash
+# 查看 GPU 设备
+lspci | grep -i vga
+
+sudo apt install clinfo
+```
+
+使用 `clinfo` 命令查看 OpenCL 版本。`C++` 程序需要定义`OpenCL`版本：
+
+```c++
+target_compile_definitions(${target_name} PRIVATE CL_TARGET_OPENCL_VERSION=300)
+```
+
+### 1.2 安装 OpenCL SDK
+
+```bash
+sudo apt install libstb-dev libsfml-dev libglew-dev libglm-dev libtclap-dev ruby doxygen -y
+
+# 安装支持包：包括ICD Loader，SDK及头文件
+sudo apt install ocl-icd-opencl-dev
+
+git clone https://github.com/KhronosGroup/OpenCL-SDK.git --recursive
+# 编译 & 安装 OpenCL SDK .....
+```
+
+* 额外安装：`Intel OpenCL Runtime`，用于支持在`CPU`上运行`OpenCL`程序（模拟`GPU` ??），需要先安装`OpenCL Loader`(Installable Client Driver Loader，`ICD Loader`)。参考 [ubuntu安装OpenCL运行及编译环境](http://liujiayi771.github.io/2019/01/18/ubuntu%E5%AE%89%E8%A3%85OpenCL%E8%BF%90%E8%A1%8C%E5%8F%8A%E7%BC%96%E8%AF%91%E7%8E%AF%E5%A2%83/)。
+
+### 1.3 参考
+
+* [Getting started with OpenCL on Ubuntu Linux](https://github.com/KhronosGroup/OpenCL-Guide/blob/main/chapters/getting_started_linux.md)
+* [CMake Build System Support](https://github.com/KhronosGroup/OpenCL-Guide/blob/main/chapters/cmake_build-system_support.md)
