注意:cuda 是对 C 的扩展,所以要用标准的 C 函数库。而我安装好后就兴冲冲地

#include <iostream>

cout<<"hello, word!";


#include <cuda.h>
#include <stdio.h>
#include <string.h>
#include <cutil.h>

int main(int argc, char** argv)
 int deviceCount;
 printf("There is no device supporting CUDA\n");
 int dev;
 cudaDeviceProp deviceProp;
 printf("\nDevice %d:\"%s\"\n",dev,;
 printf(" Revision:\t\t%d.%d\n", deviceProp.major,deviceProp.minor);
 printf(" Memory:\t\t %u M\n",deviceProp.totalGlobalMem/(1024*1024));
 printf(" SMs:\t\t %d\n",deviceProp.multiProcessorCount);
 printf(" SPs:\t\t %d\n",8*deviceProp.multiProcessorCount);
 printf(" Clock rate:\t\t %.2f GHz\n", deviceProp.clockRate*1e-6f);
 printf(" Threads:\t\t%d\n",deviceProp.maxThreadsPerBlock);
 printf(" Block Dim:\t\t%d X%dX%d\n",deviceProp.maxThreadsDim[0],deviceProp.maxThreadsDim[1],deviceProp.maxThreadsDim[2]);
 printf(" Grid Dim:\t\t%d X%dX%d\n",deviceProp.maxGridSize[0],deviceProp.maxGridSize[1],deviceProp.maxGridSize[2]);
 return 0;


There are 1 devices supporting CUDA

Device 0:"GeForce GT 220"
  Revision:    1.2
  Memory:      986 M
  SMs:         6
  SPs:         48
  Clock rate:  1.34 GHz
  Threads:     512
  Block Dim:   512x512x64
  Grid Dim:    65535x65535x1
