14:00 → 15:00 Programming future heterogeneous quantum-classical supercomputing architectures

Speaker: Alexander McCaskey, Quantum Computing Software Architect, NVIDIA

Abstract: Supercomputing architectures based on GPU acceleration have greatly improved our scientific computing workflows and applications over the past decade. Quantum computing has recently been proposed as a potential addition to this heterogeneous compute architecture, serving as another node-level accelerator to continue problem scalability in domains such as quantum many-body physics and artificial intelligence. As stand-alone quantum processing units (QPUs) continue to evolve and improve, the applied computational science community is left to wonder - how do we build, program, and deploy large-scale quantum-classical heterogeneous architectures that incorporate both GPUs and QPUs? In this talk, we will demonstrate how NVIDIA is leveraging its current suite of multi-GPU platforms to define and deploy the NVIDIA quantum platform. Specifically, we will highlight CUDA Quantum - a quantum-classical programming model in C++ with Python bindings, and associated compiler toolchain built on the MLIR and LLVM frameworks. This talk will focus on technical details of the programming model and compiler architecture and demonstrate the utility of CUDA Quantum when targeting both real and emulated quantum coprocessors.

Speaker Bio: Alexander McCaskey is a quantum computing software architect at NVIDIA, and the manager of the Quantum Computing Architecture team. His work is focused on programming models, compilers, and languages for heterogeneous quantum-classical computing. He is the lead architect for the CUDA Quantum project, a novel quantum-classical programming model in C++ and Python enabling performant workflows on heterogeneous architectures. Previously, he was a Staff Scientist at Oak Ridge National Laboratory where he led the development of the XACC system-level quantum framework and the QCOR quantum-classical C++ compiler platform. He received B.Sc. degrees in 2010 in Physics and Mathematics from the University of Tennessee, and a M.Sc. degree in physics from the Virginia Polytechnic and State University in 2014.

14:00 → 15:00 Advancing Intelligent Scheduling for Complex Large-Scale Systems

Speaker: Jing Li, Assistant Professor, Department of Computer Science at New Jersey Institute of Technology

Abstract: As computer architecture and software continue to evolve, large-scale systems like high-performance computing and supercomputers are becoming increasingly complex, consisting of diverse processing units, specialized accelerators, and complex memory hierarchies. Concurrently, scientific workflows are also growing in complexity and dynamism. Maintaining optimal application performance for timely processing while efficiently utilizing resources poses a significant challenge, exacerbated by the intricate scheduling problems inherent in these systems. Traditional ad hoc heuristic-based approaches are no longer sufficient, and manual resource allocation decisions are cumbersome and time-consuming for developers. To address these challenges, there is a pressing need for an intelligent scheduling framework capable of automating resource allocation to enhance system performance. However, existing learning-based approaches face limitations in handling combinatorial optimization, long-distance dependencies, and generalizing across diverse workflows. This talk will discuss potential avenues to leverage theoretical insights in resource allocation problems and develop efficient reinforcement learning formulations to tackle these challenges head-on.

Speaker Bio: Jing Li is an assistant professor in the Department of Computer Science at New Jersey Institute of Technology. She received her Ph.D. degree from Washington University in St. Louis in 2017. Her research interests include parallel computing, real-time systems, and reinforcement learning for system design and optimization. She has high impact publications in top conferences with three outstanding paper awards. Jing is the recipient of the NSF CAREER Award in 2024 and the Department of Energy Early Career Research Program (ECRP) Award in 2023.

11:00 → 12:00 Supercomputer-based in-silico virtual humans: the future of medicine NOW

Speaker: Mariano Vazquez, CTO / CSO, ELEM Biotech

Abstract: ELEM Biotech is a startup company of the Barcelona Supercomputing Center, BSC. We develop Virtual Humans based on supercomputing and high-fidelity mutliscale / multiphysics modellization. Together with supercomputing power and accurate modellization, we develop mathematical tools to create populations of Virtual Humans representative of Real ones. The goal is to put in the hands of the biomedical stakeholders a tool for (a) run in-silico clinical trials and (b) personalize the virtual humans to a given real patient under a certain condition. Our tools allow to improve and optimize therapies. Today we are focus on cardiac and vascular diseases. In this talk we will discuss our latest achievements.

Speaker Bio: MV is co-founder and CTO/CSO of the ELEM Biotech (The Virtual Humans Factory), a spinoff company of the Spanish Barcelona Supercomputing Center (BSC), founded with the goal of speeding-up the technology transfer of BSC modelling technology for he biomedical domain, in particular, the code Alya. He is also one of the two leaders of the Alya Development Team at the BSC, with more than 70 scientists and developers. Graduated in Physical Sciences from the University of Buenos Aires, Argentina, in 1993, he completed his bachelor's thesis on Chaos in Dynamical Systems. Doctor in Physical Sciences from the Polytechnic University of Catalonia (UPC), Spain, in 1999, he completed his doctoral thesis in Computational Fluid Mechanics (on numerical schemes for stabilization of compressible flow equations for finite elements). He has carried out post-doctoral stays at the Pole Scientifique Univ. Paris VI / Dassault Aviation (in multigrid for compressible and incompressible turbulent flow, funded by a Marie-Curie scholarship from the EC) and at INRIA Sophia Antipolis (shape optimization using the adjoint method), both in France, for 3 years. He was a consultant for the company Gridsystems (grid computing) in Palma de Mallorca (Spain) and a lecturer at the University of Girona (Spain). Since 2012 he has been a senior scientist at the CSIC, on leave since July 2018, when he co-founded ELEM. In 2004, his scientific interests experienced the irresistible grasp of computational biomedicine until this day (and counting).
