VS2019上配置CUDA的环境步骤

本贴介绍一下CUDA编程的流程

1、打开VS，新建项目（空项目即可）

2、右键项目，生成依赖项，自定义

3、勾选CUDA

4、源文件中新建.cu文件，右键.cu文件，属性没常规，项类型，选中CUDA C/C++

5、添加属性表

其中，属性表由之前配置，保存，以后项目直接添加现有属性表即可。属性表中内容为：

此处内容，请参考其他博文内容，添加cuda的相关库文件，.lib文件等等。

例程：

#include "cuda_runtime.h"
#include "device_launch_parameters.h"
#include <stdio.h>
#include <stdlib.h>
void main() {
    int deviceCount;
    cudaGetDeviceCount(&deviceCount);
    int dev;
    for (dev = 0; dev < deviceCount; dev++)
    {
        int driver_version(0), runtime_version(0);
        cudaDeviceProp deviceProp;
        cudaGetDeviceProperties(&deviceProp, dev);
        if (dev == 0)
            if (deviceProp.minor = 9999 && deviceProp.major == 9999)
                printf("\n");
        printf("\nDevice%d:\"%s\"\n", dev, deviceProp.name);
        cudaDriverGetVersion(&driver_version);
        printf("CUDA驱动版本:                                   %d.%d\n", driver_version / 1000, (driver_version % 1000) / 10);
        cudaRuntimeGetVersion(&runtime_version);
        printf("CUDA运行时版本:                                 %d.%d\n", runtime_version / 1000, (runtime_version % 1000) / 10);
