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 (pp. 7+8 only). For legal reasons, the regulations are only available in German.
Do not share your account, neither by passing on your password nor by sharing your ssh key!
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.
However, you will receive an email reminder ca. 4 weeks in advance of your account's expiration.
Staff members and Students of TU Darmstadt
- Please fill in the application form on page 7 of the document, print pages 7+8 only (duplex) and send the signed original by post to our address (please refer to the contact information on the right side).
Staff members and Students of other Hessian universities
- Please fill in the application form on page 7 of the document, print pages 7+8 only (duplex) and send the signed original by post to your local contact person.
The HRZ will establish the requested user account for the approved validity term and will inform the user by mail upon completion.
To see the expiry date of your own user account, use the script
/shared/bin/account_expire after logging in.
How to set or change my Lichtenberg password?
Using your (guest) TUID, log into the ANDO part of the IDM system of TU Darmstadt. There you should find the tab “HLR” on which you can set or change your HPC cluster password.
The change is effective immediately, you can now log in on one of our login nodes with your TUID and the chosen password and start working.
This Lichtenberg HPC cluster password is a separate one and only valid for our HPC Linux system. It is not the same as the one for your TUID or your institute's account or in sync with one of these.
Cluster-Usage for courses (teaching, workshops)
There are separate accounts for courses and workshops. Please find here more information.

Deep Learning, Tools and Fortran Modernization
The 11th installment of the HiPerCH workshop series takes place at Technical University Darmstadt on September 23-27, 2019. The workshop focuses on Deep Learning on high performance computing clusters, and related tools and languages. In addition, we hold a course on Fortran modernization in cooperation with NAG.
The HiPerCH workshops are conducted by the Competence Center for High Performance Computing in Hessen (HKHLR). They are targeted at students and scientists from Hessen, Mainz, and Kaiserslautern with interest in programming modern HPC hardware. go
Unterstützung der KI-Forschung durch Erweiterungen der Programmiersprache Python und Container
Forschung zu künstlicher Intelligenz (KI), insbesondere zu maschinellem Lernen (ML), ist in der computergestützten Forschung der letzten Jahre das zentrale Thema. Um die Wissenschaftler_innen bei der Deep Learning- und ML-Forschung auf dem Lichtenberg Cluster zu unterstützen und für seine Nutzung zu gewinnen, wurden alle im Modulsystem vorhandenen Python Installationen ergänzt. weiter
For a major storage migration inside the Lichtenberg Cluster, a two-day maintenance has been scheduled from Tuesday, 23rd to Wednesday, 24th of July 2019. Neither the compute nodes nor the login nodes will be available. go
