Representatives of HLRS will participate in the following talks and sessions:
Building International HPC Collaborations Across Continents to Tackle Grand Challenges: The HANAMI Project
Tuesday, November 19 12:15 – 1:15 PM Location: B310 Birds of a Feather Session HLRS speaker: Sophia Honisch
Science relies on intercontinental collaborations, not least in hot areas such as AI, but for historical reasons many HPC codebases tend to dominate in the region where they were developed. This duplication of effort is a major challenge as we increasingly need large teams to perform co-design to adapt to emerging HPC platforms, where expertise is a worldwide bottleneck. International cooperation is a way to address this, both for training and development of applications. This BoF will share best practices and identify existing intercontinental collaborations in HPC applications, using the recent HANAMI Europe-Japan collaboration as a starting point for discussion.
European HPC Ecosystem — Training and Skills
Tuesday, November 19 5:15 – 6:45 PM Location: B208 Birds of a Feather Session HLRS speaker: Flavio Galeazzo
In recent years, the European HPC ecosystem has undergone profound changes. The objective of this BoF is to give an overview of the current state of European HPC activities, with a particular focus on training and skills activities. We will present and discuss with international HPC stakeholders the current state of play, future plans, and challenges and critically analyze the European HPC skills and training offerings to HPC practitioners in academia and industry. With the ever-evolving technical landscape around HPC and AI, the needs for skill development are more important than ever.
Eight Years of Philosophy @HLRS — Reflections on the Past, Present and Future of a Trans-Disciplinary Project
Friday, November 22 9:40 – 10:00 AM Location: B308 Session: Ethical Social and Policy Issues in HPC HLRS speakers: Nico Formanek, Michael Resch, Andreas Kaminski
The High-Performance Computing Center Stuttgart (HLRS) has been operating a Philosophy of Computational Sciences group since 2016. Its collaboration with HLRS and external simulation scientists has covered many topics ranging from ethics and epistemology of simulations, to sociological aspects of HPC, modeling for policy, and philosophy of science of simulations. This talk will give a peek into three topics from the past, present and future of the group's work, reflecting on the opportunities and challenges of a highly trans-disciplinary collaboration.
Beyond Biomedical Simulations in Supercomputing: Ethical Challenges and Regulatory Obstacles with Boundary Conditions in Healthcare
Friday, November 22 10:30 – 10:50 AM Location: B308 Session: Ethical Social and Policy Issues in HPC HLRS speaker: Johannes Gebert, with Luka Polson
Achieving trustworthy AI systems with easy usability for all stakeholders in the healthcare sector is challenging, as trustworthiness has many facets. It has been shown that even when physicians lack knowledge or understanding, patients are usually willing to use drugs that are demonstrably safe and efficient (Boddington, 2017). Reducing the opacity of black-box AI systems is crucial for healthcare AI applications because of the moral and professional responsibility of physicians to provide reasons and explanations for their decisions (Holzinger et al., 2019). However, black-box models are common in AI and are generally thought to pose a problem for trustworthiness. Despite the fact that robotic surgical systems are as efficient as physicians, many patients still trust a surgeon more than a robotic system (Longoni, 2019). This paper explores the challenges in healthcare simulations, emphasizing the need for ethical frameworks and adaptive regulatory mechanisms to address data requirements and privacy concerns.
Dr. Theresa Pollinger will present the results of research in which her team ran a single simulation that simultaneously used Germany’s three national supercomputers: Hawk (HLRS), JUWELS (Jülich Supercomputing Centre), and SuperMUC-NG (Leibniz Supercomputing Centre).
Realizing Joint Extreme-Scale Simulations on Multiple Supercomputers — Two Superfacility Case Studies
Thursday, November 21 2:00 – 2:30 PM Location: B309 Session: Scaling and Checkpointing
High-dimensional grid-based simulations serve as both a tool and a challenge in researching various domains. The main challenge of these approaches is the well-known curse of dimensionality, amplified by the need for fine resolutions in high-fidelity applications. The combination technique (CT) provides a straightforward way of performing such simulations while alleviating the curse of dimensionality. Recent work demonstrated the potential of the CT to join multiple systems simultaneously to perform a single high-dimensional simulation. This paper shows an extension to three or more systems and addresses some remaining challenges: load balancing on heterogeneous hardware; utilizing compression to maximize the communication bandwidth; efficient I/O management through hardware mapping; improving memory utilization through algorithmic optimizations. Combining these contributions, we demonstrate the CT for extreme-scale Superfacility scenarios of 46-trillion DOF on two systems and 35-trillion DOF on three systems. Scenarios at these resolutions would be intractable with full-grid solvers (>1,000-nonillion DOF each). Read more.
