- For JUWELS-data-project, use “jibg36.”
- Provide some additional information meant for the PI/PA that will grant you access.
- The PI/PA will be automatically informed about your join request and can add you to the different systems available in the project. Once you are approved to join the project compute time, you should be able to see the project id under `Projects`.
3. Generate an SSH Key:
- Simplified instructions for SSH Key Generation: https://gitlab.jsc.fz-juelich.de/sdlts/general-organisation/jsc-supercomputer-wiki-for-ibg-3/-/wikis/SSH-Keys-at-JSC-Supercomputers
- General instructions in the JURECA manual (https://apps.fz-juelich.de/jsc/hps/jureca/access.html) to generate an SSH key.
- Use IP-Adresses of the form `x.y.0.0/16` (IPv4) or `x:y:z::/48` (IPv6) in the "from" clause, where the numbers "x", "y" and, for IPv6, "z" can be copied from the users's ip-adress displayed in the top of the JuDoor SSH-key-upload-page. Background: The later numbers of an ip-adress vary between logins. The suffix `0.0/16` (IPv4) or `::/48` (IPv6) ensures that the from-clause stays valid for these variations.
