Science in 2017-2020 believes that NSF, the science and engineering research community, and the committee itself need to consider. It is intended to stimulate discussion and prompt feedback that the committee will consider in preparing its final report.

Data-intensive computing is becoming more important as the volume of data grows, as new analytical techniques are adopted, and as some fields move from being primarily compute-intensive to being much more data-intensive. For its final report, the committee will explore and seeks comment on 1. How to create advanced computing infrastructure that enables integrated discovery involving experiments, observations, analysis, theory, and simulation.

From page 3... ...
For its final report, the committee will explore and seeks comments on 2. Technical challenges to building future, more capable advanced computing systems and how NSF might best respond to them. RESPONDING TO GROWING DEMAND Demand for advanced computing has been growing for all types and capabilities of systems, from large numbers of single-commodity nodes to jobs requiring thousands of cores; for systems with fast interconnects; for systems with excellent data handling and management; and for an increasingly diverse set of applications that includes data analytics as well as modeling and simulation.

3. The committee will review data from NSF and the advanced computing programs it supports and seeks input, especially quantitative data, on the computing needs of individual research areas. For its final report, the committee seeks comment on 4. The match between resources and demand for the full spectrum of systems, for both compute- and data-intensive applications, and the impacts on the research community if NSF can no longer provide state-of-the-art computing for its research community.

For its final report, the committee will explore and seeks comment on 7. Whether wider collection and more frequent updating of requirements for advanced computing could be used to inform strategic planning, priority setting, and resource allocation; how these requirements might be used; and how they might best be developed, collected, aggregated, and analyzed. Enhanced Organizational Stability and Flexibility of NSF-Funded Advanced Computing Centers Although NSF's use of frequent open competitions has stimulated intellectual competition and increased NSF's financial leverage, it has also impeded collaboration among frequent competitors, made it more difficult to recruit and retain talented staff, and inhibited longer-term planning.

Both top-down and bottom-up processes require mechanisms for identifying detailed needs of the directorates and their programs and for ensuring adequate community input. For its final report, the committee seeks comment on 9. How NSF might best coordinate and set overall strategy for advanced computing-related activities and investments as well as the relative merits of both formal, top-down coordination and enhanced, bottom-up process.
