For internal data transfer, please always use the host name alone, omitting the domain suffix ".hlrn.de". You can use the generic names blogin, glogin or specific names like blogin5, glogin2, etc.. This way NHR internal links are used which are faster than external routes. The latter are used when specifying fully qualified host names (blogin.hlrn.de or glogin.hlrn.de) which is not recommended here. |
Data Transfer Between Emmy (Göttingen) And The GWDG SCC
If you have previously been working on the SCC in Göttingen at the GWDG, you can follow these steps if you need to transfer data to/from the Emmy system:
- On an Emmy frontend node (glogin.hlrn.de or glogin[1-9].hlrn.de), generate a new SSH key (also documented at the SCC).
- Add the SSH key at the GWDG Website -> My Account -> Security.
- 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 usingrsync(see SCC documentation and rsync man page) to/from the SCC transfer node transfer-scc.gwdg.de. Some examples are given belowCopy a single file
