Users on Shamu are automatically granted several locations to store their files. Most users will be storing their files in one of two locations, $HOME or /work.
$HOME directory - /home-new/abc123 - This directory is entirely controlled by you and the default permissions are that nobody else can see or access your files. There are no quotas limits and this location is backed up nightly.
Work directory - /work/abc123 - This directory is where you should place any input/output files as well as logs for your running jobs. This directory is NOT backed up.
