Should we have a section in the tutorial with information like this for each of the machines we know how to use?

At the UC-HIPACC school at LBL Erik showed us how to build/run on Hopper at NERSC (I'm a regular NERSC user so this was very helpfu), and the steps were considerably different. Unfortunately I didn't write down what we did and so am now a bit stuck. So Erik, if you're reading this, could you look through your shell history and maybe dig up the commands you used? :-P
