I am a new user - Quick Start


Please note: If you have absolutely no time at all, at least read this one page. Please make sure, the following points are met.

  • Did you receive an email, confirming your addition to the Cluster-News mailing list? Important announcements, for example maintenance periods, are announced on this list.
  • Did you change your password? You can change your password using the command passwd.
  • Consider the cluster system as a tool to facilitate your research. Mastering any tool takes time. Consider attending an introductory talk and reading this Cluster Handbook.

About the cluster system


In order to meet the University’s demand for computing resources with a lot of CPUs and memory, LUIS is operating a cluster system as part of the service . All scientists of Leibniz University can use the cluster system for their research free of charge.

Resources of the cluster system are largely a DFG major instrumentation. Therefore rules1) for DFG major instrumentation apply when using the cluster system. Project leaders of your EDV-Project bear responsibility to comply with the DFG rules.

Getting Access

  • To be able to use the cluster system, you must first apply for a project
  • You can manage usernames(create, delete, change password) as part of a project
  • Usernames give you access to the cluster system

A project is the frame in which you will carry out your work on the cluster. To apply for a project, use the form ORG.BEN 4. In this form, you will need to specify the purpose of the computations you want to carry out on the cluster system as well as the type of work, e.g. a bachelor's or master's thesis or any other project of an institute. By signing the form, you agree to be bound by the terms of use that accompany the application.

In order to apply for a project, you need to have the formal authority to sign. Students can only get an account while working at an institute.

Once your project has been approved, you as a project leader can log in to the BIAS website and create usernames.

Please note: Each username should reflect the real name of the user by choosing the suffix accordingly.

Note that user accounting on BIAS is not part of the service Scientific Computing and thus not part of the cluster system.

What the cluster system may be used for

Parts of the cluster system are DFG major instrumentation, thus rules for DFG major instrumentation apply when using the cluster system. Furthermore software licenses are valid for research and teaching only. Accordingly the cluster system must only be used for research and teaching activities.

Computing power

Currently the cluster system consists of the following compute resources, see table Computing Hardware

Additionally institutes can integrate their own hardware for use within the cluster system in the service called (FCH). This hardware is accessible only to the respective institute during the day, i.e. between eight o’clock in the morning and eight o’clock in the evening. During night-time all cluster users have access to the resources.

If you get directed to a machine that does not fit the name scheme of our main clusters during that time period, it is most likely a FCH participant. For information about having your own hardware in the , please get in touch.
