In order to meet the demand at the university for increased computing power and increased memory requirements, the IT Services offer massively parallel computing systems and computers with large main memory. These computers are available for all employees of the Leibniz University of Hannover free of charge.

Access to the cluster system

In order to create user accounts for the cluster, you first need to register a project at the computing center. In the prerequisites section you can find instructions on which forms you need to fill out and how to then create user names. The hashes of the host key fingerprints of login.cluster.uni-hannover.de are as follows:

Getting started with the cluster system

In order to facilitate your start with the cluster system, we provide a handbook, an introductory talk and a cheatsheet. Please read the cluster system handbook carefully before starting your work - many questions are already answered here.

Of course we will be happy to assist you with any questions you might have via the central support address cluster-helpluis.uni-hannover.de or in person.
