ASCR at a Glance
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.

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, highcapacity 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.
DOE Applied Mathematics
Support the research and development of applied mathematical models,
methods and algorithms for understanding natural and engineered systems
related to DOE’s mission.
Long-term goals:
•
•
•
•
Mathematics research that 5-10+
years out will impact DOE mission
efforts: DOE Applications, SciDAC
Partnerships, and Exascale Co-Design
New Mathematical Multifaceted
Integrated Capability Centers
(MMICCs) directly enhances impact of
applied math on DOE mission
Cross-cutting mathematics projects: addresses foundational, algorithmic and extremescale mathematical challenges
High-risk, high-payoff: new mechanism to bring in highly innovative research

Mathematical Multifaceted Integrated Capability Centers (MMICCs)
• Background
•
2005 Multiscale Mathematics solicitation
•
15 projects awarded under Multiscale Mathematics
and Optimization of Complex Systems (ending 8/2012)
•
7 projects awarded under Mathematics for Complex
Distributed Interconnected Systems (ending 8/2012)
•
7 projects awarded under ARRA Multiscale
Mathematics and Optimization of Complex Systems
(ending 8/2012)
• Workshop: Sept 13-15, 2011; Workshop report, “A Multifaceted Mathematical Approach for
Complex Systems” March 2012.
• 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.

Mathematical Multifaceted Integrated Capability Centers (MMICCs)
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
