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);
printf("设备计算能力: %d.%d\n", deviceProp.major, deviceProp.minor);
printf("Total amount of Global Memory: %u bytes\n", deviceProp.totalGlobalMem);
printf("Number of SMs: %d\n", deviceProp.multiProcessorCount);
printf("Total amount of Constant Memory: %u bytes\n", deviceProp.totalConstMem);
printf("Total amount of Shared Memory per block: %u bytes\n", deviceProp.sharedMemPerBlock);
printf("Total number of registers available per block: %d\n", deviceProp.regsPerBlock);
printf("Warp size: %d\n", deviceProp.warpSize);
printf("Maximum number of threads per SM: %d\n", deviceProp.maxThreadsPerMultiProcessor);
printf("Maximum number of threads per block: %d\n", deviceProp.maxThreadsPerBlock);
printf("Maximum size of each dimension of a block: %d x %d x %d\n", deviceProp.maxThreadsDim[0],
deviceProp.maxThreadsDim[1],
deviceProp.maxThreadsDim[2]);
printf("Maximum size of each dimension of a grid: %d x %d x %d\n", deviceProp.maxGridSize[0], deviceProp.maxGridSize[1], deviceProp.maxGridSize[2]);
printf("Maximum memory pitch: %u bytes\n", deviceProp.memPitch);
printf("Texture alignmemt: %u bytes\n", deviceProp.texturePitchAlignment);
printf("Clock rate: %.2f GHz\n", deviceProp.clockRate * 1e-6f);
printf("Memory Clock rate: %.0f MHz\n", deviceProp.memoryClockRate * 1e-3f);
printf("Memory Bus Width: %d-bit\n", deviceProp.memoryBusWidth);
}
system("pause");
//return 0;
}
