When I run testing routine, facing error: error while loading shared libraries: libcudart.so.6.5: cannot open shared object file: No such file or directory.
Solution for this, copy respect library to /usr/local/lib:
sudo cp /usr/local/cuda-6.5/lib64/libcudart.so.6.5 /usr/local/lib/libcudart.so.6.5 && sudo ldconfig
sudo cp /usr/local/cuda-6.5/lib64/libcublas.so.6.5 /usr/local/lib/libcublas.so.6.5 && sudo ldconfig
sudo cp /usr/local/cuda-6.5/lib64/libcurand.so.6.5 /usr/local/lib/libcurand.so.6.5 && sudo ldconfig
