Event Description: IXPUG Annual Conference 2022 will feature keynote/invited talks, 30-minute technical sessions, lightning talks, site updates, and hands-on tutorials. The conference draws expert software developers, scientists, researchers, academics, systems analysts, students, and end-users for technical discussion and networking. 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.
