Access for scientists and research
In order to get your personal and personalized user account (or to extend its validity term) for the Lichtenberg high performance computer, the following user regulations have to be accepted and signed (form on pp. 7+8). For legal reasons, the regulations are available only in German (a translation is provided).
The HRZ will then set up the requested user account for the approved validity term, and will inform you by mail upon completion.
Do not share your user account (neither password nor ssh
keys)! Collaboration is permitted only by being members in a common project.
Please note: the validity term of the HLR user accounts is completely independent of any associated project!
As projects may have several users and any given user might be associated with several projects, there is no easy way of unison. Your user account could thus expire even while you are associated with a project still running.
To see the expiry date of your own user account, use the script /shared/bin/account_expire
after logging in.
Apart from that, you will receive an email reminder ca. 4 weeks in advance, and at the exact day of your account's expiration.
