University IT and Data Center

The University IT and Data Center (Hochschulrechenzentrum, HRZ) is the central IT service provider of the University of Bonn

Introduction of JupyterHub

The University Computer Centre is now supporting the use of the multi-user data science platform JupyterHub, which allows users to work in their own interactive environment directly in the browser.

JupyterHub allows its users to use many programming languages (like Python, R und Julia)  in so-called Jupyter notebooks. Jupyter notebooks are standardised files that enable the creation, management and sharing of program codes.

This enables e.g. teachers, to provide their participants with a standardised but customisable learning environment via eCampus, without having to install software on the end devices first.
JupyterHub users automatically receive 5GB of storage space for their personal Jupyter server. Specifications such as CPU or RAM limits can also be set individually for course participants.

HPC-Cluster Marvin resumes testing mode

"Marvin", the supercomputer installed at the University of Bonn in 2023, is about to be released. The cluster, consisting of 192 MPP nodes with a total of 18400 computing cores and an additional 300 NVIDIA GPUs, which was unveiled to the public in a festive inauguration event on 20 October 2023, is now about to be released.

After technical difficulties during the cooling of the cluster, the first testing phase had to be interrupted from the beginning of December until mid-February. During these two months, intensive work was carried out to make the cooling system more reliable and to protect the cluster hardware and the running jobs in the event of incidents.

The operations team at the University Computing Centre is now pleased to announce that the additional security mechanisms have been successfully tested, meaning that the HPC cluster could be put back into operation on Tuesday, 13 February 2024. This marks the start of the second intensive test phase, in which highly experienced "power users" can use the cluster again for numerical simulations and at the same time report possible problems and hickups to the data centre's maintenance team.

This also means that the supercomputer nears its official release to the general user base: Registration for the use of the HPC cluster is expected to be open to all scientists at the University of Bonn and its cooperation partners from 11 March 2024.
