cuda开发环境

cudatoolkit的下载和安装

CUDA Toolkit Archive | NVIDIA Developer

cudnn下载和安装

cuDNN Archive | NVIDIA Developer

2.VSCode扩展插件安装

扩展中安装Microsoft： C/C++

NVIDIA： Nsight Visual Studio Code Edition

3.程序调试

新建.cu文件，完成代码编写。

这里为矩阵加为例，add.cu

代码编写过程中可通过观察cuda函数是否自动补全来检验2中的插件是否正确安装。

单击左侧功能菜单“运行和调试”，通过选择cuda-c++（cudagdb）调试器。新建launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "CUDA C++: Launch",
            "type": "cuda-gdb",
            "request": "launch",
            "program": ""
        },
        {
            "name": "CUDA C++: Attach",
            "type": "cuda-gdb",
            "request": "attach"
        }
    ]
}

然后新建tasks.json

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "mynvcc",		#自定义
            "type": "shell",
            "command": "nvcc",
            "args":["-g","-G", "-o","${fileDirname}/add","${file}",
            	#需要的头文件，和动态库
                "-I", "/usr/local/cuda/include",
                "-I", "/usr/local/cuda/samples/common/inc",
                "-L", "/usr/local/cuda/lib64",   
                "-L", "/usr/local/cuda/samples/common/lib",  
                "-l", "cudart",                           
                "-l", "cublas",
                "-l", "cudnn",
                "-l", "curand",
                "-D_MWAITXINTRIN_H_INCLUDED"  
            ]
        }
    ]
}

根据tasks内容补充launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "CUDA C++: Launch",
            "type": "cuda-gdb",
            "request": "launch",
            "program": "${fileDirname}/add", 	#编译生成的可执行程序             
            "preLaunchTask": "mynvcc"  			#tasks label
        },
        {
            "name": "CUDA C++: Attach",
            "type": "cuda-gdb",
            "request": "attach"
        }
    ]
}

配置完成后。单击“开始调试”或F5，开始调试。界面如下：
