Before you run a simple program, you need to:

1) Setting environment variables

 export PATH=/usr/local/cuda/bin:$PATH
 export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH

2) go to the directory of your sample code.

 For example:
 cd /home/username/cuda

3) nvcc hello_world.cu

4) You will see the output: a.out
