ISC 22 Announces Distinguished Speaker Series Lectures

May 11, 2022 — The ISC Guest Program explores developments that HPC and adjacent technologies are currently experiencing and predicts future trends, enabling users and vendors to make informed decisions. The topics of the guest program are normally proposed by experts and practitioners in various fields. This year’s Distinguished Speaker Series will feature the following speakers and topics.

Topic: Simulation of intense lasers and plasmas: numerical opportunities and challenges

Date: tuesday 31 may

The description: The next generation of lasers will reach intensities greater than 10^23 W/cm^2. When plasmas or relativistic electron beams interact with these lasers, energy loss due to radiation emission or quantum effects such as the creation of electron-positron pairs become important to their dynamics. The repeated occurrence of pairing can induce a so-called “QED cascade”, which generates an exponentially increasing number of particles. This makes it possible to create exotic plasmas which are a mixture of electrons, ions, positrons, energetic photons and intense background fields. Extreme laser-plasma interactions can be explored to form optical traps, create and accelerate particles, and produce new sources of radiation. I will introduce a QED module coupled to the massively particle-in-cell framework OSIRIS which allows to study the nonlinear dynamics of the plasma in the transition from the classical interaction regime to the quantum-dominated interaction regime. The simulation of these environments brings new computing challenges, which will be discussed with the proposed solutions.

Director and Board Member of the German Research Center for Artificial Intelligence (DFKI)

Subject: Digital reality: from models learned via synthetic data to trusted AI – and back!

Date: tuesday 31 may

The description: For AI systems to make the right decisions, they need to accurately “understand” the complex reality of the world around them. Learning models directly from observed data is often very difficult, if not impossible. Instead, we need to take a modular approach of independently learning partial models of many different aspects of the world and putting them together as needed. The simulations – not only of partial models but also of the sensors of the AI ​​system – then make it possible to generate exactly the synthetic data required for specific use cases. This can involve the training of AI systems, but also the benchmarking, validation and, most important for the industry, the certification of “Trusted-AI” systems which provide guarantees as to their functionality. . But these “Trusted-AI” systems must also understand what they don’t understand about their environment in order to improve their numerical models of reality. In this talk, I will describe “digital reality”, a global approach developed at DFKI that combines modeling, simulation, AI and high performance computing in a unique and integrated way.

Anders Jensen Dam

Speaker: Anders Dam Jensen

Topic: The European Joint Undertaking for High Performance Computing (EuroHPC JU) – European supercomputing leader

Date: Wednesday, June 1

Description: Anders will present his organization, the European Joint Undertaking for High Performance Computing (EuroHPC JU). The EuroHPC JU brings together the resources of the European Union, 31 European countries and 3 private partners to develop a world-class supercomputing ecosystem in Europe. Anders will present the first operational EuroHPC supercomputers located across Europe and give details of their access policy.

Anders will then present some of the missions of the JU, such as the acquisition of new supercomputers including exascale systems and quantum computers, the implementation of an ambitious research and innovation program supporting European technological and digital autonomy and the development of green technologies in HPC, the further strengthening of Europe’s leading position in HPC applications and the launch of the first pan-European Master of Science program in HPC, as part of the JU’s efforts to broaden the use of HPC in Europe.

Topic: NHR – Germany’s answer to HPC transformation

Date: Wednesday, June 1

The description: The German federal and state governments have agreed to jointly fund the National High-Performance Computing Alliance (NHR) with 600 million euros. NHR is a national network of Tier 2 HPC centers with concerted efforts across the entire HPC spectrum, from infrastructure and software to method development and applications. NHR is focused on excellence in research, consulting, services and training for the HPC community, understanding that scientific innovation with societal benefits often requires high quality support and sufficient capacity rather than a race for the biggest supercomputer. The alliance is broad enough to provide solutions for traditional HPC applications as well as Big Data, AI and new forms of demand from scientific communities with little HPC affinity before. The presentation will provide an overview of the structure and organization of NHR as well as projects and new developments.
