8:00 AM - 9:00 AM	Registration in Duncan Student Center 7th Floor
9:00 AM - 10:00 AM	Keynote : Physics-Aware, Full-Stack Software to Accelerate Practical Quantum Computing Abstract Quantum software can be a force multiplier that can significantly shorten the timeline for utility-scale results from quantum hardware. In particular, several key research directions will help realize practical quantum advantage. Physics-aware, cross-layer optimizations will continue to yield important efficiencies to allow applications to make the most of quantum resources. Software-directed noise-aware optimization and error correction, in particular, will be key to increasing gate depths and maintaining acceptable output fidelity. Pulse-level optimizations and specialized native gates will also be key enablers. Additionally, applications will be hybrid computations involving high-performance classical resources as well as quantum hardware serving as special-purpose accelerators. Effectively partitioning computations between these classical and quantum resources will be necessary to support realistic applications. Additionally, deep compiler optimization and classical simulation of Clifford and near-Clifford circuits can also be important classical investments towards more efficient quantum computations. Finally, defining abstractions that control compiler complexity yet selectively expose key physical machine properties will also be a key area of research. Speaker: Fred Chong, University of Chicago Biography Fred Chong is the Seymour Goodman Professor in the Department of Computer Science at the University of Chicago and the Chief Scientist for Quantum Software at Infleqtion. Chong is a member of the National Quantum Advisory Committee (NQIAC) which provides advice to the President on the National Quantum Initiative Program. In 2020, he co-founded Super.tech, a quantum software company, which was acquired by Infleqtion (formerly ColdQuanta) in 2022. Chong received his Ph.D. from MIT in 1996 and was a faculty member and Chancellor's fellow at UC Davis from 1997-2005. He was also a Professor of Computer Science, Director of Computer Engineering, and Director of the Greenscale Center for Energy-Efficient Computing at UCSB from 2005-2015. He is a fellow of the ACM and the IEEE, a recipient of the NSF CAREER award, the Intel Outstanding Researcher Award, and 16 best paper awards. He is also a recipient of the Quantrell Award, the oldest undergraduate teaching award in the United States, as well as the University of Chicago's Graduate Teaching and Mentoring Award.

1:00 PM - 2:00 PM	Industry Talk Talk #1: The HPC Revolution: Accelerating the Future of Science and AI Abstract High-Performance Computing (HPC) is not just a service we offer; it is part of Google's foundational DNA. This presentation explores the deep history of HPC within Google, from the early days of massive-scale indexing and distributed computing with technologies like MapReduce and Borg, to the sophisticated infrastructure that powers our global services today. We will trace this unique evolutionary path, demonstrating how decades of internal innovation in running planetary-scale workloads have directly informed the architecture and capabilities of Google Cloud's HPC offerings. Attendees will learn how this heritage translates into a robust and flexible cloud ecosystem designed to support the most demanding research challenges. Furthermore, we will delve into how Generative AI is revolutionizing the very methods of HPC development and management. We will discuss how services like Gemini Code Assist are accelerating the creation of complex simulation code and simplifying workflow scripting, while platforms like Google Colab provide an accessible environment for prototyping and analysis. Through real-world case studies in fields such as genomics and climate science, we will highlight how our infrastructure, now augmented by AI-powered tools, is empowering researchers to push the boundaries of discovery. Finally, we will look to the future, discussing how Google is continuing to democratize access to world-class HPC, fostering innovation, and helping the scientific community solve the grand challenges of tomorrow.

9:00 AM - 10:00 AM	2025 HPDC Achievement Award Keynote : Designing for Trust, Transparency, and Efficiency in Scientific Computing Abstract Today, scientific computing workflows are increasingly operating at scales where nondeterminism, opaque AI decisions, and rising energy demands are no longer exceptions—they have become the norm. In this talk, I will present the concrete methods we are using to address these challenges within the scientific discovery process. Specifically, I will demonstrate how graph-based analysis can reveal sources of nondeterminism in large High-Performance Computing (HPC) simulations, how fine-grained provenance frameworks can enhance transparency in AI-driven workflows, and how predictive engines can eliminate redundant computations in neural architecture search, thereby significantly reducing energy costs. Beyond individual solutions, I will outline a broader vision for computing that integrates data, experiments, and computation into comprehensive scientific ecosystems, exemplified by the National Science Data Fabric (NSDF). The talk will connect technical advancements to the larger goal of producing scientific results that are trustworthy, explainable, and efficiently generated at scale. Speaker: Michela Taufer, University of Tennessee, Knoxville Biography Dr. Michela Taufer, an American Association for the Advancement of Science Fellow and Association for Computing Machinery Distinguished Scientist, holds the Jack Dongarra Professorship in High-Performance Computing (HPC) at the University of Tennessee, Knoxville.
