Where did CUDA get installed in my computer?

Question

I'm trying to install CUDA 7.5 in my ubuntu 14.04. I followed everything in this guide (installation through package): http://developer.download.nvidia.com/compute/cuda/7.5/Prod/docs/sidebar/CUDA_Installation_Guide_Linux.pdf until post build section. Mainly, by running the following commands:

sudo dpkg -i cuda-repo-ubuntu1404-7-5-local_7.5-18_amd64.deb sudo apt-get update sudo apt-get install cuda 

The thing is the folder /usr/local/cuda* does not exist after successful CUDA installation. Further trying to install cuda says that it is already the newest version.

sudo apt-get install cuda Reading package lists... Done Building dependency tree        Reading state information... Done cuda is already the newest version.  ls /usr/local/cuda* ls: cannot access /usr/local/cuda*: No such file or directory 

It also does not find nvcc.

nvcc The program 'nvcc' is currently not installed. You can install it by typing: sudo apt-get install nvidia-cuda-toolkit  sudo find /usr/ -name nvcc <no output> 

What is wrong?

Answer 1

Usually, it is /usr/local/cuda. If this is not the case, you can try to locate cuda. If you want to find directories only, run

locate cuda | grep /cuda$ 

or

find / -type d -name cuda 2>/dev/null 

For me, it turned out to be in /opt/cuda-7.5
