What is the Difference in Between Cuda Files?

Accelerated Computing GPU-Accelerated Libraries

Hi Everyone,

I have installed Cuda-9.1 and there existed two files of cuda in the local file, which one of them is cuda and the other one is cuda-9.1. I have two questions:

  1. What is the difference in between?
  2. Now, I want to install cudnn. Regarding the cudnn installation guide, there says that copy the files into the CUDA Toolkit directory as following:
sudo cp cuda/include/cudnn.h /usr/local/cuda/include
$ sudo cp cuda/lib64/libcudnn* /usr/local/cuda/lib64
$ sudo chmod a+r /usr/local/cuda/include/cudnn.h
/usr/local/cuda/lib64/libcudnn*

My question is that in which CUDA Toolkit directory i should copy the files? cuda or cuda-9.1?

Kind regards, Ender.

cuda is a symbolic link to cuda-9.1

Read about linux symbolic links (google that). Then you will discover that the answer to your question about where to copy the files to is “it does not matter”.
