Here we show a simple example of how to use the CUDA C/C++ language compiler, <code>nvcc</code>, and run code created with it. For a longer tutorial in CUDA programming, see [[CUDA tutorial]]. | Here we show a simple example of how to use the CUDA C/C++ language compiler, <code>nvcc</code>, and run code created with it.

To run the program, create a Slurm job script as shown below. Be sure to replace <code>def-someuser</code> with your specific account (see [[Running_jobs#Accounts_and_projects|accounts and projects]]).
