All machines in coover 2050 are installed with CUDA.

Before you run a simple program, you need to:

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

1) go to the directory of your sample code.

2) To compile hello_world.cu

  nvcc hello_world.cu

3) This will generate an executable file: a.out

5) ./a.out

The cuda sample code can be downloaded from:CUDA by example

hello_world.cu is in chapter03.
