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!
