Maybe you have already noticed – the changeover to a new Linux distribution on the CLAIX has been going on for some time. Now it goes into the final phase, so that the old operating system CentOS 7 will be replaced by Rocky Linux 8.7. It is compatible with Red Hat Enterprise and brings a few changes.

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.

MPI Runtime Correctness Analysis

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.
