Keynote 1 - Advancing Scientific Discovery with the National Scientific Data Fabric: Democratizing Data Access and Use through Reproducibility, Analytical Tools, and User-Focused Services

Michela Taufer
Jack Dongarra Professor in High Performance Computing, The University of Tennessee Knoxville


In the evolving landscape of scientific research, we deal with the challenge of harnessing data from remote experimental sites and repositories. The obstacles we face are technical, logistical, and financial, calling for immediate and innovative solutions to move scientific discovery forward across the domains. Scientists’ quest for seamless data access and real-time analysis spans various applications, from guiding experiments with synchrotron light sources to leveraging the immense datasets from leading computing facilities. This imperative need goes beyond geographical boundaries and individual domains.

In this talk, we discuss the National Scientific Data Fabric (NSDF), a cutting-edge platform designed to transform data management in converging HPC-cloud environments to democratize data access for enhanced scientific discovery. NSDF integrates user-centric networking, storage, and computing, simplifying HPC and cloud complexities for data analysts and boosting scientific reproducibility and clarity. We focus on the NSDF testbed, showcasing service integration for improved data management and scientific workflow reproducibility. The testbed uniquely merges global and local networks, advanced storage, and powerful computing, ensuring interoperability and efficient data handling.

A key part of the talk is NSDF's application to the SOMOSPIE workflow, a machine-learning model in earth science. This demonstrates the testbed's support for complex analyses in academic and commercial clouds. The SOMOSPIE case study underscores the NSDF’s ability to handle complex data and its vital role in augmenting reproducibility and clarity in scientific research.

Keynote 2 - Exascale computing solutions inspired by plasma physics simulations

Michael Bussmann
Founding Manager of Center for Advanced Systems Understanding (CASUS), Helmholtz-Zentrum Dresden-Rossendorf


The nonlinear nature of complex plasma physics phenomena has been a driver of developments for high performance computing. With the advent of Exascale computing, the use of heterogeneous compute architectures, complex workflows, interactive online visualization and analysis and the integration of machine learning and simulation have taken the center of the stage. In my talk I will motivate the need for these technologies coming from our research in advanced particle accelerators and light sources and fusion research. Here, the integration of simulation with experiments at large scale research facilities creates a paradigm shift on the role and use of simulations in research. I will then present the key solutions we at HZDR have developed to move our simulation code PIConGPU to the Exascale era. These include the Alpaka library for single-source, performance portable heterogeneous computing and the openPMD ecosystem for Exascale I/O, streaming online analysis and complex workflows. I will conclude by presenting recent results on coupling Exascale plasma simulations and online training of AI models on streaming simulation data on the Frontier Exascale compute system as a teaser of what to expect in the future.

Keynote 3 - Deep Codesign in the Post-Exascale Computing Era

Jeffrey Vetter
Section Head of Advanced Computing Systems Research, Oak Ridge National Laboratory


DOE has just deployed its first Exascale system at ORNL, so now is an appropriate time to revisit our Exascale predictions from over a decade ago and think about post-Exascale. We are now seeing a Cambrian explosion of new technologies during this this ‘golden age of architectures,’ making codesign of architectures with software and applications more critical than ever. In this talk, I will revisit Exascale trajectory, survey post-Exascale technologies, and discuss their implications for both system design and software. As an example, I will describe Abisko, a new microelectronics codesign project, that focuses on designing a chiplet for analog spiking neural networks using novel neuromorphic materials like electrochemical random access memory.
