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 an introductory talk, a handbook and a cheatsheet. May we suggest to begin with the video to get a first overview. Please continue with the cluster system handbook before starting your work — or at least have a look. Most of the frequently asked questions are already answered there.

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.
