Dear Richard,

There is some response for cudadetect command which I have pated in earlier mail. But no ./cudadetect file.

rb@rameshbabu:~$ ./cudadetect
bash: ./cudadetect: No such file or directory

I have nvcc file in /usr/local/cuda/bin but still not located.

rb@rameshbabu:~$ which nvcc  (no response)
rb@rameshbabu:~$ ll /usr/local/cuda/bin/

rb@rameshbabu:~$ nvcc --version
The program 'nvcc' is currently not installed. You can install it by typing:
sudo apt install nvidia-cuda-toolkit

As far as I know, freesurfer supports cuda-5 and it requires libcudart.so-5.0. That's why I have installed cuda-5. How did you enable freesurfer with cuda-8?

Thanks
Ramesh

cudadetect is installed by freesurfer. For me, the output starts:
[rge21@cudastation gpu_utils]$ ./cudadetect
Detecting CUDA... There is 1 device supporting CUDA:

Device 0: "Quadro K1200"

Did you install the CUDA SDK? The response from your OS implies you
didn't (likewise the absence of /usr/local/cuda). However, if you did,
then check your $PATH.

[rge21@cudastation gpu_utils]$ which nvcc

Did you install CUDA yourself? What is the output from "locate libcudart" ?

Richard
