参考了：CUDA 01 | 第一个程序 - 知乎 (zhihu.com)

1 本地安装插件：remote-ssh，Microsoft C/C++与NVIDIA Nsight Visual Studio Code Edition。

2 使用remote-ssh登陆到远程的linux服务器，登陆以后看看安装的插件，需要在远程linux服务器也同时安装插件。确保提到的三个插件在远程端是可以用的。

3 确保在远程linux服务器已经安装了cuda编译器，没有装的话点下面的链接，输入命令 nvcc -V查看安装情况。

CUDA Toolkit 11.7 Update 1 Downloads | NVIDIA Developerhttps://developer.nvidia.com/cuda-downloads

langke@ubuntu:~/my_cuda$ nvcc -V
nvcc: NVIDIA (R) Cuda compiler driver

4 新建一个目录用来测试，例如~/my_cuda，用vscode打开此目录

5 在.vscode下新建lauch.json，内容如下：

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "CUDA C++: Launch",
            "type": "cuda-gdb",
            "request": "launch",
            "program": "${fileDirname}/${fileBasenameNoExtension}",
            "args": [], 
            "stopAtEntry": false,
            //"cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "setupCommands": [
              {
                "description": "Enable pretty-printing for gdb",
                "text": "-enable-pretty-printing",
                "ignoreFailures": true
              }
            ],
            "preLaunchTask": "nvcc build active file",
            "postDebugTask": "delete nvcc output file",
          }
    ]
}

 6 新建tasks.json，内容为：

{
    "version": "2.0.0",
    "tasks": [
        {
            "type": "shell",
            "label": "nvcc build active file",
            "command": "/usr/local/cuda-10.2/bin/nvcc",
            "args": [
                "${file}",
                "-g",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        },
        {
            "type": "shell",
            "label": "delete nvcc output file",
            "command": "rm",
            "args": [
                "${fileDirname}/${fileBasenameNoExtension}"
            ],
            "presentation": {
                "reveal": "silent"
            },
            "problemMatcher": [],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ]
}

7 新建test.cu，输入内容：

#include <iostream>


int main(int argc, char **argv)
{
    printf("cuda test\n");
    getchar();
    return 0;
}

8 把窗口切换到test.cu，点击CUDA调试按钮就可以运行了。
