【IT168 文档】1、 软件准备
cudadriver_2.3_winvista_64_190.38_general
cudatoolkit_2.3_win_64
cudasdk_2.3_win_64
VS2008
安装前将之前安装的sdk、toolkit、driver等卸载，再依次安装上述软件。如果开发平台没有支持CUDA的显卡，则不需要安装cudadriver_2.3_winvista_64_190.38_general。
2、 安装检查
在cmd下执行nvcc –V可以查看当前版本号
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2009 NVIDIA Corporation
Built on Mon_Aug__3_19:43:55_PDT_2009
Cuda compilation tools, release 2.3, V0.2.1221
执行bandwidthtest查看配置是否正常
进入ProgramDataNVIDIA CorporationNVIDIA GPU Computing SDKCbinwin64Release>目录，执行
.bandwidthTest.exe --memory=pinned --mode=range --start=10240000 --end=10240000 -increment=10240000
若正常会有类似信息

&&&& Test PASSED
Press ENTER to exit...
执行deviceQuery.exe查看显卡具体型号
. deviceQuery.exe
若正常会有类似信息
CUDA Device Query (Runtime API) version (CUDART static linking)
There is 1 device supporting CUDA

根据信息可以推算显卡的单精度浮点处理性能为3*32*1.13=108.48Gflops
3、 设置系统环境变量
将安装的CUDA的sdk的路径加到系统环境变量中：
例如C:ProgramDataNVIDIA CorporationNVIDIA GPU Computing SDKCbinwin64
下的
├─Debug
├─EmuDebug
└─EmuRelease
几个目录都加入到系统环境变量PATH中，这样才能在运行程序的时候找到相应的dll库。
将编译需要的头文件放到vs2008环境中
复制C:ProgramDataNVIDIA CorporationNVIDIA GPU Computing SDKCcommon目录到C:UsersdawningDocumentsVisual Studio 2008下
4、 VS2008建立CUDA简单的工程
将模板项目C:ProgramDataNVIDIA CorporationNVIDIA GPU Computing SDKCsrc template拷贝到vs2008项目目录C:UsersdawningDocumentsVisual Studio 2008Projects
打开vs2008，打开模板项目template_vc90
