 If you want to share bigger datasets with other users on the cluster you can request shared storage on the cluster. It will be located under /home/Shared/. Please specify the usernames of all users that should be able to access this data (and any other hepful informations for us regarding your reequest) in an [[gsg+lmgpu@informatik.uni-bonn.de|informal request email]].

 +===== Email Notifications =====
 +
 +If you want to receive email notifications about the status of your jobs, you can specify a recipient email address at job submission, i.e.:
 +
 +sbatch --mail-type=ALL --mail-user=someuser@somedomain.com ...
