The NHR systems in Berlin ("Lise") and Göttingen ("Emmy") are equipped with various file systems each. Their properties and their intended utilization are described here.

Disk quotas based on group ownerships are implemented on each site's global (non-local) file systems.

1. On an Emmy frontend node (glogin.hlrn.de or glogin[1-9].hlrn.de), generate a new SSH key (also documented at the SCC).
2. Add the SSH key at the GWDG Website -> My Account -> Security.
3. From an Emmy frontend node (glogin9.hlrn.de has access to both Emmy and Grete scratches, while glogin.hlrn.de and glogin[1-8].hlrn.de only have access to the Emmy scratch; but all have access to $HOME ), transfer the files using rsync (see SCC documentation and rsync man page) to/from the SCC transfer node transfer-scc.gwdg.de. Some examples are given below

   • Copy a single file FOO  from SCC $HOME into your current directory on Emmy

     Codeblock
     language bash
     rsync GWDGUSERNAME@transfer-scc.gwdg.de:/usr/users/GWDGUSERNAME/FOO .

     
     

   • Copy a single file FOO in your current directory on Emmy to $HOME  on the SCC


     Codeblock
     language bash
     rsync FOO GWDGUSERNAME@transfer-scc.gwdg.de:/usr/users/GWDGUSERNAME/

     
     

   • Copy a directory in your SCC /scratch  to your current directory on Emmy


     Codeblock
     language bash
     rsync -r GWDGUSERNAME@transfer-scc.gwdg.de:/scratch/projects/workshops/forest/synthetic_trees .

     
     

   • Copy a directory in your current directory on Emmy to /scratch  on the SCC


     Codeblock
     language bash
     rsync -r synthetic_trees GWDGUSERNAME@transfer-scc.gwdg.de:/scratch/projects/workshops/forest/
