Dirk Roose is an emeritus professor at KU Leuven, Department of Computer Science. He chaired the KU Leuven HPC Steering Committee, played an important role in the start of the Flemish Computer Center (VSC), and chaired the user committee of the VSC. We sat down with em. prof. dr. Roose for an elaborate talk. In this first part of the interview series, he sheds light on the challenges in the early days of HPC, the current challenges and why he is so fascinated by this domain. Dive with us into memory lane together with Prof. Roose!

Prof. Dirk Valkenborg is the Programme director of the data science trajectory in the Master of Statistics & Data Science at UHasselt. He teaches a course on Machine Learning in this programme, and during this course, his students use the supercomputing infrastructure of The Flemish Computer Center. We sat down with Prof. Valkenborg to ask him why he is so keen on getting his students enthusiastic about working with a supercomputer.

MPI heavyweight Dr Rolf Rabenseifner has recently retired. However, we could catch the former Head of Parallel Computing, Training and Application Services at the High-Performance Computing Center Stuttgart (HLRS), University of Stuttgart, for an extensive talk.

LUMI is the fastest supercomputer in Europe and the fifth fastest globally (the Top500 list published in November 2023). LUMI is also the seventh greenest supercomputer on the planet (the Green500 list published in November 2023). 

The LUMI data center was also recognized in the 2023 Data Centre World Awards for the Green Data Centre of the Year in March 2023.
