Then

 nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2015 NVIDIA Corporation
Built on Tue_Aug_11_14:27:32_CDT_2015
Cuda compilation tools, release 7.5, V7.5.17

And finally

which nvcc
/usr/bin/nvcc

But my installation directory is

ldconfig -p | grep cuda
    libnvrtc.so.8.0 (libc6,x86-64) => /usr/local/cuda-8.0/targets/x86_64-linux/lib/libnvrtc.so.8.0
    libnvrtc.so (libc6,x86-64) => /usr/local/cuda-8.0/targets/x86_64-linux/lib/libnvrtc.so
    libnvrtc-builtins.so.8.0 (libc6,x86-64) => /usr/local/cuda-8.0/targets/x86_64-linux/lib/libnvrtc-builtins.so.8.0
    libnvrtc-builtins.so (libc6,x86-64) => /usr/local/cuda-8.0/targets/x86_64-linux/lib/libnvrtc-builtins.so

Is this ok?Why is nvcc pointing to other directory?

Is this ok?

Yes, everything is as expected.

Why is nvcc pointing to other directory?

nvcc lives on the typical folder for executables whereas the others are CUDA "drivers". It's mostly a Nvidia decision but it makes sense.
