All machines in coover 2050 are installed with CUDA.
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
5) ./a.out
It will print the result.
