On May 23, 2023, the server certificate of our authentication server “radius.rz.rwth-aachen.de” had expired. For that reason a new certificate was implemented in the system. In the first post of this blog series we informed you about this.
Now a larger change is coming up: In the future, the new certification instance GÉANT/TCS will be used and replace DFN-PKI Global. As a consequence a new Radius certificate and certification chain will be used. This migration will take place on August 1, 2023.
Eduroam will be affected with regard to registration and configuration. The exact background and what you have to do, to continue using eduroam, we will explain in the following blog post. Read the rest of this entry »

H2M – More Control and Efficiency in Systems with Heterogeneous Memory

In the DFG-funded project “Heuristics for Heterogeneous Memory” (H2M), RWTH Aachen University and the French project partner Inria are jointly developing support for new memory technologies such as High Bandwidth Memory (HBM) and Non-Volatile Memory (NVM). These technologies are increasingly used as additional memory in HPC systems alongside the common Dynamic Random Access Memory (DRAM). HBM offers higher bandwidth than classic DRAM but is also much smaller. NVM provides larger capacities but is slower compared to DRAM. The different characteristics and capacity limits thus raise the question of how systems with heterogeneous memory can be used efficiently and in which memory data should be stored.

The Wi-Fi network eduroam is available on the entire campus of the RWTH Aachen University. If you have already configured eduroam on your mobile devices and chosen an automatic connection, your devices will connect to eduroam in the background. This happens as soon as your devices detect a network with the name eduroam in the vicinity.
Behind a secure connection to eduroam lie certificate structures that guarantee this security. But how exactly do these processes work? In the following blog post, we hope to provide answers to these and other questions.
