VS2019上配置CUDA的环境步骤
作者:一叶孤舟渡
本文主要介绍了VS2019上配置CUDA的环境步骤,文中通过图文示例介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友们下面随着小编来一起学习学习吧
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; }
