[CUDA is not detected by CMake, building without it] despite CUDA and Tesla T10 being present

[Ujjwal Aryan]

Hi,

I tried to install Caffe in my home folder with GPU Support. I have a Tesla T10 GPU on the system. I have checked by running deviceQuery script in /usr/local/cuda-5.0/samples and it confirms that Tesla T10 GPU is active with compute capability 1.3 

When I configure using ccmake in my build directory, I observe that though all the CUDA libraries are automatically detected, it gives an error that "CUDA is not detected by CMake, building without it." 

I could not make heads or tails of this since I checked all the paths and CUDA drivers and libraries were installed. 

I am building with  OpenCV 2.3 I realised that the minimum version specified on the Caffe Webpage is 2.4, but I could not understand how this could be the source of the problem, as the error message does not mention OpenCV at all.

I am back from the lab, and hence cannot post any outputs or messages right now, but if someone would like some further information, I would be able to provide it first thing in the morning.

I just want to know that is there any reason for this kind of error which someone else has faced before ? Any inputs would be greatly appreciated.

Regards

Ujjwal

Caffe requires compute capability >= 2.0 and strictly greater than 2.0 is suggested. CMake not detecting CUDA could be a configuration issue with paths, or it could be the CUDA capability check failing: https://github.com/BVLC/caffe/blob/master/cmake/Cuda.cmake#L5-L7

At any rate, you will need another GPU.
