• Fermilab LPC Environment Setup
  • Disk space
    • ~/.cache
    • VSCode Remote SSH

Disk space

Your home directory (~ or /uscms/home/<username>) only has 2GB of disk space. This means you should install conda / mamba, CMSSW releases, VSCode remote servers, work repositories etc. in your ~/nobackup directory (200GB disk space)!. See https://uscms.org/uscms_at_work/computing/setup/diskusage.shtml.

Some other tricks:

~/.cache

The ~/.cache directory can sometimes fill up the home directory. To avoid this you can move it into ~/nobackup and create a "symbolic link" to it:

cd ~
mv .cache nobackup/
ln -s nobackup/.cache .cache

VSCode Remote SSH

To use VSCode on LPC with the remote-ssh plugin, you need to install it in the nobackup directory. See https://stackoverflow.com/questions/62613523/how-to-change-vscode-server-directory/70979632#70979632.
