Who can use MOGON?

Access to MOGON NHR is granted to scientists in Germany. MOGON II is available to scientists of research institutions and universities in the state of Rhineland-Palatinate.

How do I get an account?

We need to distinguish two cases:

Your work group already has an HPC project account on MOGONPlease ask your group’s MOGON contact (technical contact person for a project group) to add you to your group’s project on this site . If in doubt who to contact, feel free to approach us for looking it up.
Your work group needs to apply for its access to our clusters

MOGON NHR: Scientists with a doctoral degree who belong to a German accredited university are eligible to apply for HPC projects. The electronic applications can be accessed on the central NHR website .

MOGON II: All principal investigators within Rhineland-Palatinate are eligible to apply for an HPC project using this form (in German) or this form (in English) . Please do not hesitate to contact us beforehand or if in doubt.

External users

External non-JGU users can use the form on this page to apply for a JGU guest account.

Internal groups with external members should approach their person in charge of accounts at the deanery of your faculty or at the secretariat of the respective institution.

How does it differ from my standard JGU user account?

Unix user and group management on MOGON are separate from the other JGU account management. We synchronize most changes in user accounts with MOGON automatically. However, some actions need to be performed manually.

What happens when my account gets disabled or expires?

When your JGU account is determined to be no longer valid for using MOGON1, it will first become disabled on MOGON23 (you can no longer login, but your user and home directory still exist). If your account is re-enabled within 90 days, all your files will still be there. If an account has been disabled for 90 days, the user and home directory will be deleted3. Your files in the group’s project directory will become owned by the first technical administrator of your group.

What should I consider when being member of several MOGON groups?

In order to facilitate subsequent accounting with slurm we enforce that accounts are given at the time of submitting a job. All accounting data are gathered. For the purpose of writing project reports and determining of accumulated CPU times accounts and their associated projects job statistics are gathered.

Note that the account slurm is aware of is an arbitrary project name, which is not the username4.

So, which accounts are applicable for you? This is as simple as

sacctmgr -s list user $USER format=account%20

Note, that all users have a none account. This is part of the mechanism which enforces accounts to be during job submits. The %20 expands the column width to 20 characters, use a number to your convenience, if that does not suffice.
