A little background first, I am a complete novice at GPU computing and this is the first time attempting it. Here is my current setup:
Windows 7 Professional x64
2 GeForce GTX 650s
Visual Studio 2012 Ultimate
CUDA 5.5 installed
current video driver installed: 320.18
Using the recommended install everything seemed to go smoothly for the CUDA 5.5 install toolkit. Afterwards I tried to run some of the samples provided and got an error that I had no current CUDA devices installed. So after going through the documentation I ran deviceQuery.exe and it gave back the following: “no CUDA-capable device detected Result = FAIL”.
If I am not mistaken there is a CUDA driver, which is separate from the graphics driver, that needs to be installed to be able to develop for CUDA. It can be installed either silently or via a GUI during the CUDA toolkit installation. The problem is that I don’t ever recall getting the window for a specific CUDA driver install. I went through the installer again and still didn’t see any mention of a specific CUDA driver, just a graphics driver.
Am I missing something somewhere?
