Download the hands-on files from here if you don't have them already. If you need to upload the files to the CSUC machines, you can do it from a terminal from your own machine using scp:
scp -P 2122 conda-hands-on.tar.gz username@hpc.csuc.cat:
Note the uppercase P and the colon, :, at the end of the command.
Connect to CSUC HPC machines from a terminal:
ssh -p 2122 username@hpc.csuc.cat
You will now find yourself at your $HOME directory at one of our login nodes. Extract the files in the tarfile, and move into the resulting directory:
tar xvf conda-hands-on.tar.gz && cd conda-hands-on
You are now ready to begin the exercises.
