10:15 11:15 Keynote: Extreme Computing and Extreme Events in the Environment

Dr. Kiran Bhaganagar, Professor, Department of Mechanical Engineering; Associate Fellow American Institute of Aeronautics & Astraunautics (AIAA); Director for Laboratory of Turbulence, Sensing & Intelligent Systems; Director of NASA Center for Advanced Measurements in Extreme Environments (CAMEE) at University of Texas at San Antonio. Bhaganagar had rigorous training as a Ph.D. student under the guidance Prof John Lumley, world’s leading experts on turbulence. Bhaganagar’s expertise is in the area of turbulence model development for atmospheric plumes, rough-wall turbulent boundary layer, leeway drag due to the combined interactions of wind and wave turbulence. Recently, Bhaganagar served as a principal investigator for the following: United States Coastal Guard, Integrated high-fidelity approach towards improved leeway drift prediction, NASA MIRO Center for Advanced Measurements in Extreme Environments; US Army, Novel Technology for detection and prediction of spreading of air-borne chemical agent. Bhaganagar has contributed to numerical tools, including WRF-LES to simulate 2-way feedback between the ABL and the plume, DNS of rough-wall turbulent channel flow, LES of wake effects of wind turbine, a novel technology for leeway detection due to the interaction of wind and current.

Event Description: This Intel eXtreme Performance Users Group (IXPUG) conference is focused on all aspects of adopting and employing state-of-the-art technologies and practices for optimal application execution on Intel XPU platforms. The challenges surrounding application performance and scalability will be covered across all levels, including tuning and optimization of diverse sets of applications on large-scale HPC systems. This includes system hardware beyond the processor (memory, interconnects, etc.), accelerators (e.g., GPUs, FPGAs), as well as topics related to oneAPI, software tools, programming models, HPC workloads, and more.
Key themes: high-performance computing, data analytics, artificial intelligence (machine learning and deep learning), HPC in the cloud, and COVID-19 related biomedical simulations and data analytics applications.
The conference draws expert software developers, scientists, researchers, academics, systems analysts, students, and end-users. It will feature keynote/invited talks, 30-minute technical sessions, lightning talks, hands-on tutorials, and site updates. Each year IXPUG brings together speakers from a wide variety of HPC organizations, renowned industry leaders, and Intel experts to share their real-world experiences, best practices, and techniques for maximizing software productivity and efficiency. Be part of this interactive, open forum with live Q&A!
