What kinds of questions can
CS&E help answer for DOE?
• Can we predict the operating characteristics of a clean
coal power plant?
• How stable is the plasma containment in a Tokamak?
• How quickly is climate change occurring and what are the
uncertainties in the predicted time scales?
• How quickly can the US recover if part of the power grid
became inoperable?
• How can new materials be designed with a specified
desirable set of properties?

Answering these and other important questions involves study

CS&E Community Involvement
• Learn more about ASCR programs
• Be a reviewer
• Panel reviews
• “Postal” reviews
• Participate in DOE workshops
• ASCR-sponsored
• Basic Energy Sciences (BES), Biological and
Environmental Research (BER), Electricity
Delivery and Energy Reliability (OE), Energy

New “Breakthroughs” report
• Each of Mathematics, Computer
Science, and Applications will
have a “breakthroughs” report to
support FY11 DOE budget
request
• Each report will look back about
eight years – the SciDAC era
• What are the ten most important
mathematical breakthroughs to
computational science?
• Not necessarily scaling issues,
could be “more science per
flop/byte stored/byte transmitted”
• Please send your suggestions to
