Title: Topological Analysis for Exascale Computing: Approaches & Challenges
Time: Tuesday, 28 May 2019 at 1.00 pm
Room: Powerwall Room University of Stuttgart, VISUS, cellar
Simulation has quickly evolved to become the “third” pillar of science and supercomputing centers provide the computational power needed for accurate simulations. Furthermore, there are concentrated efforts in the Exascale Computing Project to cross the next barrier and build a supercomputer that can run simulations at quintillion calculations per second. This talk provides an overview over how topological data analysis has helped in abstracting and analyzing simulation results. It furthermore outlines the challenges that current developments in supercomputer architecture pose to efficient algorithm design for topological data analysis and presents initial solution approaches.
Gunther H. Weber received a Ph.D. in computer science, with a focus on computer graphics and visualization, from the University of Kaiserslautern, Germany in 2003. He is currently a Staff Scientist in the Computational Research Division at the Lawrence Berkeley National Laboratory (LBNL), where he serves as Deputy Group Lead of the Data Analysis and Visualization Group in the Data Science and Technology Department. Gunther Weber is an Adjunct Associate Professor of Computer Science at the University of California, Davis. His research interests include computer graphics, scientific visualization, data analysis with using topological methods, parallel and distributed computing for visualization and data analysis applications, hierarchical data representation methods, and bioinformatics. He has extensive experience in working with researchers from diverse science and engineering fields, including applied numerical computing, combustion simulation, gene expression, medicine, civil engineering, cosmology, climate and particle accelerator modeling. Dr. Weber has authored or co-authored over 80 publications, five of which won best paper awards. He has served as principal investigator (PI) or Co-PI on several Department of Energy (DOE) and National Science Foundation (NSF) projects. He is a reviewer for major funding agencies (DOE, NSF), conference proceedings and journals. Dr. Weber served as co-organizer, co-chair and program committee member of more than 40 internationally recognized conferences.
