3. ASCR at a Glance 3 ASCR Mission: Discover, develop, and deploy the computational and networking capabilities that enable researchers to analyze, model, simulate, and predict complex phenomena important to the Department of Energy.

4. ASCR Research Programs Applied Mathematics- basic research in models, methods, and algorithms for understanding complex natural and engineered systems related to DOE’s mission Computer Science- basic research in utilization of computing at extreme scales; understanding extreme scale data from both simulations and experiments Next-Generation Networking for Science - focuses on end-to-end of high-performance, high- capacity and middleware network technologies necessary to provide secure access to distributed science facilities, high-performance computing recourses and large-scale scientific collaborations. This program builds on results from applied mathematics and computer science to develop integrated software tools and advanced network services. Computational Partnerships- –SciDAC Institutes- methods, algorithms, libraries & methodologies for achieving portability and interoperability of complex scientific software packages; software tools and support for application performance; tools for data analytics, and visualization spanning the full range of SciDAC applications –Scientific Application Partnerships (SAPs)- enable computational scientists to effectively and confidently utilize multi-petaflop computing systems to advance science. –Co-Design- close coupling of applications, computer science, and computer hardware architecture that are required for success at exascale.

Applied Math Summit 3/7/2012. New Paradigm Holistically address mathematics for increasingly complex DOE-relevant systems for scientific discovery, design, optimization and risk assessment. Broader view of the problem as a whole, and devise solution strategies that attack the problem in “its entirety” by building fundamental, multidisciplinary mathematical capabilities Enable applied mathematics researchers to work together in large, collaborative teams to more effectively address science problems earlier in the problem solving process.

7. Mathematical Multifaceted Integrated Capability Centers (MMICCs) Mathematical Multifaceted Integrated Capability Centers (MMICCs) 7 Proposals for a Mathematical Multifaceted Integrated Capability Center must: Address the long-term mathematical challenges for one or more DOE grand challenges and that require new integrated, iterative processes across multiple mathematical disciplines. Identify a set of interrelated mathematics research challenges that represent abstractions of the grand challenges. These abstractions would then be optimally addressed through a multifaceted, integrated approach. Advance multifaceted, integrated mathematics that spans, as appropriate, novel formulations, discretizations, algorithm development, data analysis techniques, uncertainty quantification methodologies, optimization techniques, and other mathematical approaches; Have impact to the DOE mission in the 5-10+ year timeframe
