由于我的电脑是windows10,显卡是集显Intel® UHD Graphics 630。
下载Intel的SDK for OpenCL,下载地址https://software.intel.com/en-us/opencl-sdk/choose-download
,也可以在我的资源里面直接下载
http://xiazai.jb51.net/202305/yuanma/intel_sdk_for_opencl_applications_283428.rar
运行install.exe,安装
运行后,如果vs打开了需要关闭。
默认安装路径在C:\Program Files (x86)\IntelSWTools,找到OpenCL安装位置在C:\Program Files (x86)\IntelSWTools\system_studio_2020\OpenCL
配置环境变量,发现以及自动配置到里面了
下载intel提供测试工具,下载地址:https://download.csdn.net/download/qq_36314864/87756581
然后下载了直接运行,打印如下表示安装成功。
自己搭建一个OpenCL工程,创建一个C++控制台工程
打开配置属性,包含OpenCL的头文件,即将C:\Program Files (x86)\IntelSWTools\system_studio_2020\OpenCL\sdk\include
添加依赖项,如果工程是x64,就在C:\Program Files (x86)\IntelSWTools\system_studio_2020\OpenCL\sdk\lib\x64下面,如果x86就依赖x86下面的
拷贝下面测试代码替换helloword
