Research is done by people to help other people understand the world we were born into. It is crucial to communicate work and results. Otherwise, the whole undertaking, spending of financial resources and time would be pointless. While some of the final theses we supervise are industrial ones with a business critical need for secrecy, my own research is open to public.
In addition to presenting results, I am actively engaged in organizing workshops and volunteer at conferences to support people getting together. Science can be communicated online without a need to meet in person. But since research is done by people, networking and strong personal relationships that are build in-person in my experience are the best way of driving science.
USTUTT | Interview | November 2022 | Stuttgart, Germany
Univ.-Prof. Dr.-Ing. Oliver Riedel invited five PhD students for an interview about doing a doctorate at the University of Stuttgart. The department of mechanical engineering of USTUTT is among the strongest in respect to their research activities and offers a strong curriculum. However many PhD student will move on and may be found in research or industry once they complete their dissertation. We used the opportunity of an interview for the magazine of the department of mechanical engineering at the Fraunhofer IAO for discussing issues relating to the undertaking of a PhD.
Is there anything better than fighting alone? Yes. Discussing with other people and taking good advice.
SC22 | Research Poster | November 2022 | Dallas, Texas, USA
The submission of a research poster marks the completion of my research internship at the Innovative Compting Laboratory (ICL) of the University of Tennessee, Knoxville which started in April 2022. We conducted research about computationally informed machine learning algorithms for use in high-performance computing. The results currently are in the process of publication.

SC22 | Exhibition | November 2022 | Dallas, Texas, USA
The Supercomputing not only is a high-value conference in High-Performance Computing, but it is a fare for Soft- and Hardware in HPC as well. HLRS presented its abilities in computing, visualization and its engagement in national and international collaborations. The Porsche 911 GTS was marked by my colleague Dr.-Ing. Uwe Wössner, head of Visualization, for overlaying the video stream by a camera with the results of a Computational Fluid Dynamics Simulation (CFD). It was a pleasure supporting HLRS on SC22.
Computing and presenting results of scientific applications is one of the key competences of HLRS.
WSSP34 | Presentation | October 2022 | Sendai, Japan
Prof. Kobayashi-sensei and his colleagues of the Cyberscience Center at the Tohoku University in Sendai hosted me and my colleagues from HLRS to join the Workshop on Sustained Simulation Performance. The talk aimed at performance enhancements like we opted for at the Innovative Computing Laboratory, but with a focus on Hawk, the flagship computer of HLRS. On the one hand, energy savings regarding my software-stack are a goal of my studies and on the other hand, other strategies for energy saving in respect to the whole supercomputer were part of the discussion.
The Workshop was held in Sendai, which is connected to Tokyo by the Shinkansen.
ICl/UTK | Research Internship | April-August 2022 | Knoxville, Tennessee, USA

WCCM-APCOM | Presentation | August 2022 | Online/Yokohama, Japan
Saving computational effort by orders of magnitudes always is a good thing. We achieve that by computing effective stiffness matrices with directly discretized irregular graphs. This proved being much faster than computing them based on directly discretized computed tomography scans. The speed up is a result of a significant reduction of degrees of freedom.
This method can improve simulations of structures similar to foams, sponges or more heterogeneous ones. At its gists the structure must correspond to an irregular graph. In addition, investigations on the graph may show histomorphological measures otherwise unknown.
ESMC22 | Presentation | July 2022 | Galway, Ireland
I had the pleasure to resent our new approach to topologically optimize sub volumes of patient specific implants, thus whole implants in the long term. A first plastic based 3D-print visualized the idea for the audience. Discussions showed that by all the way still up front, the approach of optimizing implants is promising.
In another step, assembling a structure topologically optimized by the corresponding field of reduced stiffness matrices will show the feasibility of bone-implant-systems.

PASC22 | Volunteering | June 2022 | Basel, Switzerland
Many branches of research profit by the use of high-performance computing. While many people work on computers to make them faster, many others try to exploit the computational power of such machines. PASC22 was an opportunity to learn from both categories; to improve my own understanding of their mindsets and requirements.
The organization of conferences like PASC relies on many motivated volunteers and employees to ensure that no one will recognize the organizational efforts. I am glad for having the opportunity to support as such a volunteer and to get in touch with and to learn from those colleagues making PASC an event to enjoy.

WSSP33 | Organization | May 2022 | Stuttgart, Germany
The workshop was held at HLRS. With Prof. Jack Dongarra as our special guest and keynote speaker, we covered the range from doctoral students to the winner of the Turing Award 2021. It was a pleasure to organize this workshop and to coordinate our colleagues of HLRS who did a great job of hosting the scientific community.
We are in the process of publishing the contributions to the proceedings of the Workshops on Sustained Simulation Performance 31 and 32. The previous book is available at Springer.
WSSP32 | Presentation | December 2021 | Online/Sendai, Japan
High-performance computers are not build to serve themselves. Instead, workflows for research or product development are to be supported. My presentation at WSSP32 covered the components of my workflow for outlining the use of different hardware architectures and their specific benefits. Most parts of my workflow are uploaded for use in this repository.
