From:

1. Got Cuda SDK https://developer.nvidia.com/cuda-downloads

2. Got Cudafy.NET

Installed SDK: C:\Users\dave\Documents\CudafySDK

Can’t find the 2010 C++ compiler

Setting up the path and my x64 machine

 
Still didn’t work…

Okay can get it working by doing vcvars32 from the shell, then cl works.

C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE

Got rid of error by following http://stackoverflow.com/questions/2970493/cuda-linking-error-visual-express-2008-nvcc-fatal-due-to-null-configuratio and making an amd64.bat:

I solved the problem by 1. installing Windows SDK (don't forget to choose all x64 options for 64 bit OS) 2. include "c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64" in PATH 3. create file vcvars64.bat inside directory "c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64" with following content: call "C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\SetEnv.cmd" /x64

Note: I did this because: 1. I am using VC++ Express 2010 2. I dont have "vcvars64.bat" in any directory ??

 

The cudafy installer RunTest still showed:

but example seems to compile and run!

Exploring how to program for an MSI 7970 graphics card.

openCL

170MB

AMD APP SDK 2.8 - 180MB
AMD Acceleratd Parallel Processing SDK is a .. apps accelerated b AMD Stream Technology
Installed driver for CPU only

PDF guide from main menu
samples in My Documents/AMD

    can get samples working!

Got a binarySearch working in C++ on the CPU – as laptop had a NVidia card  and these examples were against AMD GPU.

Got it working on VS2010 C++ Express, then installed CUDA SDK, then samples ran after a compile (took 15mins?)  Lots of errors, but ran.
