All machines in coover 2050 are installed with CUDA.

Before you run a simple program, you need to set up environment variables

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

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

1) Go to the directory of your sample code.

2) To compile hello_world.cu

  nvcc hello_world.cu

3) Run the executable file: a.out

 ./a.out

4) Get the output.

  Hello, World!

Also, a very good beginning tutorial Intro to CUDA
