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.

Free online courses on the subject of supercomputing

How is a supercomputer constructed? How is a supercomputer used and what significance does the use of supercomputers have for modern science?

These basic questions will be developed in an online course in English from 24 September on the e-learning portal "". The course is aimed at anyone interested in supercomputing, high-performance computing and state-of-the-art computer technology. The course was developed by the Partnership for Advanced Computing in Europe (PRACE) and the Edinburgh Parallel Computing Centre (EPCC) at the University of Edinburgh in collaboration with the research organisation SURFsara from the Netherlands.
