High performance computers under attack all over Europe

According to news services (e.g. several computing centers all over Europe reported attacks on their high performance computing systems in recent days. Some of them had to block all access to their systems or even shut them down temporarily.

Given the first analyses the HPC systems of the RRZK are not compromised. Nevertheless we are asking all users of our HPC systems (e.g. CHEOPS) to change their passwords via uniKIM:

If you are using ssh keys to access the servers, please also generate and use a new one.

This only affects a part of our users. If you never explicitly requested access to the HPC systems of the university, there is nothing to do on your side. 

In general please be aware never to use the same passwords or ssh keys on different locations. In the current situation by no means you should use a password or ssh key on the HPC systems of the UoC which you also use somewhere else. 

The computing centers are working together in the Gauß-Allianz and the Gauß Center to analyze the incidents and to coordinate their further strategy.

German scientist is awarded with the PRACE Ada Lovelace Award from the 'Partnership for Advanced Computing in Europe (PRACE)'

Dr. Alice-Agnes Gabriel, Department of Earth and Environmental Sciences Geophysics, Ludwig-Maximilians-University of Munich (LMU) is the winner of the 2020 PRACE Ada Lovelace Award for HPC for her outstanding contributions to and impact on HPC in Europe.

New high-performance computer at RRZK

On 5 July 2019, the Joint Science Conference (GWK) decided on the recommendation of the German Council of Science and Humanities (WR) to fund a new high-performance computer at the University of Cologne. CHEOPS 2 will - besides providing a powerful computing infrastructure - support research focused on the analysis of large amounts of data as well as the methodical improvement of simulation and visualization.

The 11.1 million euros will be used to expand CHEOPS 2 in two phases in the coming years. The required space is already available: The new high performance computer will be housed in the new server hall at the RRZK.

It will not only be available to the university's core profile areas, but also to a proportion of scientific users from all over Germany.
