As off-chip memory accesses nowadays dominate the overall power consumption of many compute platforms, accurate DRAM power simulation models are an important tool for system designers. Unfortunately, existing open-source models only support older generations of DRAM standards, while current system designs mainly rely on the newest generation including DDR5, LPDDR5 or HBM3.

Im Rahmen der Vorlesung „Amateurfunk“ von Prof. Dr. Matthias Jung (DL9MJ) an der Julius-Maximilians-Universität Würzburg unternahm am 08.11.2024 eine Gruppe von Studierenden einen Ausflug zum Amateurfunkzentrum Unterfranken. Die Lehrveranstaltung zielt darauf ab, insbesondere Studierende des Studiengangs Luft- und Raumfahrtinformatik auf die Amateurfunkprüfung der Klasse E vorzubereiten.

Together with researchers at University of Hannover, University of Braunschweig and RPTU Kaiserslautern-Landau, we presented a study on phyiscal memory fragmention in Linux, which we think is going to become an increasing problem for huge-frame availability, DRAM energy consumption and cloud memory pricing. The joint paper was awarded with the best paper award.
