CyberBridges 2013 – Developing the Next Generation of Cyberinfrastructure Faculty for Computational and Data-enabled Science and Engineering CyberBridges 2013 – Developing the Next Generation of Cyberinfrastructure Faculty for Computational and Data-enabled Science and Engineering Welcome to the NSF CyberBridges 2013 Workshop! Overview of the NSF CyberBridges Workshop The NSF CyberBridges 2013 Workshop has been designed to bring together the community of NSF OCI/ACI CAREER researchers to initiate new collaborations, encourage networking, and to provide feedback to NSF on how to further build the community of cyberinfrastructure researchers. The workshop offers a scientific program in five critical areas of cyberinfrastructure that include: Interdisciplinary Research and Grand Challenges in Cyberinfrastructure, Computational- and Data-enabled Science and Engineering, High Performance Computing, Visualization, and Education. Over the next two days, leaders from each of these areas will present keynote talks on topics ranging from data enabled molecular modeling and visualization to high performance computing. NSF program directors will also give presentations on programs that involve cyberinfrastructure and will participate on a panel which will offer insight into developing a research program in cyberinfrastructure. Another highlight of the program is the poster session, in which NSF CAREER Awardees will present posters featuring topics such as studies of 3D dynamics in the global magnetosphere, multiscale sensing and simulations for bridge scour, scalable communications, high performance computing and visualization in earthquake modeling, as well as other topics. The workshop also offers several opportunities for networking and discussion of cyberinfrastructure challenges. We hope that you will find the workshop useful for meeting new colleagues, developing new research connections, and gaining new insights in developing a research and education career in cyberinfrastructure.

To achieve this, CISE supports investigator-initiated research in computer and information science and engineering, fosters broad interdisciplinary collaboration, helps develop and maintain cutting-edge national cyberinfrastructures for research and education, and contributes to the developments of a computer and information technology workforce with skills essential for success in the increasingly global market. This talk will focus on the technological advances and emerging frontiers that are accelerating the pace of discovery and innovation across all science and engineering disciplines and how they inform NSF’s investments. In particular, it will describe the CISE Directorate’s current initiatives and emerging priorities, including new research opportunities. These efforts provide a foundation for economic competitiveness and will drive new innovations supporting our national priorities, such as sustainability, smart transportation, disaster resilience, education and life-long learning, public safety and national security. 9:00-9:30am Alan Blatecky, Division Director, Advanced Cyberinfrastructure, National Science Foundation 10:00-10:30am - Computational- and Data-enabled Science & Engineering Big Data Meets Big Models: Towards Solution of Large-Scale Bayesian Inverse Problems Omar Ghattas, John A. and Katherine G. Jackson Chair in Computational Geosciences, Professor of Geological Sciences and Mechanical Engineering, and Director of the Center for Computational Geosciences in the Institute for Computational Engineering and Sciences at the University of Texas at Austin One of the greatest challenges in computational and data-enabled science and engineering (CDS&E) today is how to combine complex data with large-scale models to create better predictions. This challenge cuts across every application area within CDS&E, from the geosciences to materials to chemical systems to biological systems to astrophysics to engineered systems in aerospace, transportation, buildings, and biomedicine, and beyond. At the heart of this challenge is an inverse problem: we seek to infer unknown model inputs CyberBridges 2013 – Developing the Next Generation of Cyberinfrastructure Faculty for Computational and Data-enabled Science and Engineering (parameters, source terms, initial or boundary conditions, model structure, etc.) from observations of model outputs. The critical need to quantify the uncertainty in the solution of such inverse problems has gained increasing recognition in recent years. This can be carried out in a coherent manner by casting the problem as one in Bayesian inference. Here, uncertain observations and uncertain models are combined with available prior knowledge to yield a probability density as the solution of the inverse problem, thereby providing a systematic means of quantifying uncertainties in the model parameters. This facilitates uncertainty quantification of model predictions when the resulting input uncertainties are propagated to the outputs. Unfortunately, solution of such Bayesian inverse problems for systems governed by large-scale, complex computational models with large-scale, complex data has traditionally been intractable. However, a number of advances over the past decade have brought this goal much closer. First, improvements in scalable forward solvers for many classes of large-scale models have made feasible the repeated evaluation of model outputs for differing inputs. Second, the exponential growth in high performance computing capabilities has multiplied the effects of the advances in solvers. Third, the emergence of MCMC methods that exploit problem structure has radically improved the prospects of sampling probability densities for inverse problems governed by expensive models. And fourth, recent exponential expansions of observational capabilities have produced massive volumes of data from which inference of large computational models can be carried out. 12:30 -1:00pm - High Performance Computing William Gropp, Thomas M.
