Access and User Regulations
General Scientific/Research Usage
For accessing and using the Lichtenberg cluster as a scientist, the following is necessary:
1) Project : A project must be set up to which the computing time used can be billed (booked) for. Please submit a for this purpose. Project Application
Usually the project application is submitted by the project manager. NHR Large and NHR Normal projects are scrutinized scientifically (according to the conditions of the NHR4CES Resource Allocation Board ( )). Small projects will just be checked technically for feasibility. RAB
2) User account: A user account must be activated which is assigned to a project, i.e. the project manager specifies who is assigned to the project. The user account is assigned to exactly one person and is managed via TU-ID. For this purpose, an application for using the high-performance computer must be submitted: Application form
Your user account (2) can be extended even without valid/running project, for you to have access to your research data even after end of a project (eg. to transfer and back up data from the file systems of the HPC to your own storage).
Lectures and workshops
For utilizing the Lichtenberg cluster in the context of lectures and courses, please find further details under “. Lectures and workshops
Recommendation: In order to have a smooth and efficient start when working with the Lichtenberg-HPC, we advise all new users to attend the ”Introduction to the Lichtenberg High Performance Computer" mentioned below.
Information for new users

Introduction to the Lichtenberg High Performance Computer
2022/03/10
Attendance is free of charge
For the (potential) users of the Lichtenberg supercomputer, an introduction is being held every second Tuesday a month. Subjects are the available hardware and software and the general use of the (batch) system. This will take place in hybrid mode (presence and webinar).
