||||||

## 1.简介
|
||||||
|
|
||||||
|
OpenCL（Open Computing Language），即开放计算语言，最初由苹果公司(Apple)提出，后交由非盈利组织Khronos维护。使用OpenCL可以让程序内部并发地执行。
|
||||||
|
|
||||||
|
## 2.使用指南
|
||||||
|
|
||||||
|
### 2.1克隆仓库
|
||||||
|
|
||||||
|
```git
|
||||||
|
git clone git@gitlab.dc.com:bianbu/graphics/k1x-gpu-test.git
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2.2进到源码目录使用cmake进行编译
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd k1x-gpu-test/openGLDemo
|
||||||
|
cmake .
|
||||||
|
make -j
|
||||||
|
```
|
||||||
|
|
||||||
|
编译完成后会在当前目录下生成 gpu-addDemo 文件，直接运行即可：./gpu-addDemo。如需安装，可在当前目录（即源码目录）下执行 make install 命令，会自动将可执行文件安装到 /usr/local/bin/ 目录下，安装完成后可直接运行：gpu-addDemo。
|
||||||
|
|
||||||
|
### 2.3添加Demo
|
||||||
|
|
||||||
|
如果增加一个名为 testDemo.c 的文件，并希望编译得到名为 testDemo 的可执行文件，可按以下示例修改CMakeLists.txt
|
||||||
|
|
||||||
|
```CMake
|
||||||
|
