At least a little less than a dozen of Europe’s supercomputers were taken offline simultaneously in May 2020. Several university centres in Europe have been attacked by hackers and had to go offline. The unknown perpetrators hacked the accounts of the users in order to gain access to the supercomputers. Fortunately, our high-performance computer was not affected, but JURECA, JUWELS and JUDAC at the Jülich Supercomputing Centre, Hawk at the Stuttgart High Performance Computing Centre and the supercomputers at the Leibzig Computing Centre (LRZ), for example, fell victim to the attack.

Just a quick blink and 2022 is already over.
Now we are standing in the middle of the first chapter of 2023.
Last year was characterized by many changes, especially based on the motto “ away from online – towards presence”.
We are looking back at the past year and take you with us.

The year is coming to an end, and we would like to look back with you on our blog series The IT Center Picture Puzzle. Which departments were involved this year and what were the solution words? We would also like to give you a sneak preview of what will happen next year, because #SpoilerAlert: we will continue the series next year. But let’s start at the beginning…

#MeetMeWednesday: Recently we had another picture puzzle in store for you. In this puzzle, we were looking for the keyword for the Systems and Operation department. Could you guess it?
The word we were looking for was “gearwheel”. Georg Schramm, head of the department, tells us what it means and how this key word represents the department.

High performance computing (HPC) is largely concerned with parallelizing programs, especially complex simulations such as models for weather forecasting or climate. To ensure that computations finish quickly, the work to be done is divided among different processes in parallel. Depending on the use case, the processes must exchange their intermediate results with other processes at program runtime.
