Sustainability and User Requirements:Recommendations for NSF

Direct supercomputing program evolution to sustain and promote resource stability

Commit to stable and sustained funding for HPC centers

Encourage HPC centers to build long-term relationships with multiple vendors

• Allow researchers and HPC centers to select best value in computational and data platforms

• Enable centers to offer continuous service to the community

• Allow centers to recruit and develop the expertise needed to maximize potential of hardware investments

• Use rigorous review and oversight processes to provide assurance that centers are meeting expectations

• Provide researchers with benefits of planned roadmap for several generations of chip technology and with continuity in architecture and software environments

• Apply results-oriented acquisition strategies to ensure that vendor performance meets center and NSF needs

Applications at the exascale:Recommendations for NSF

• Expand partnerships with industry, academia, and other agencies to accelerate development of exascale systems and applications– Co-design will be critical in development of applications

that can deliver predictive capability

• Expand efforts to engage new user communities in HPC– Focused outreach program to industry– Engagement of data-intensive fields of research

• Provide a funding framework for co-location of archive and community data resources with compute and visualization resources

• Establish a continuing process for soliciting community input on plans for HPC investments

10 NSF Advisory Committee for CyberinfrastructureHigh Performance Computing Task Force

Broader Engagement:Preliminary recommendations to NSF

• Continue and grow education, outreach, and training programs to expand awareness and encourage use of high-end modeling and simulation capabilities – Industry

– New user communities

– Expanded workforce development programs, starting with K–12

• Measure program impacts– Expansion in use of HPC

– Delivery of science

• Consider establishment of a computational science program or division

11 NSF Advisory Committee for CyberinfrastructureHigh Performance Computing Task Force

HPC Taskforce:Summary recommendations to NSF

• Develop a sustainable model to provide the academic research community with access, by 2015–2016, to a rich mix of HPC systems that:– Deliver sustained performance of 20–100 petaflops on a broad range

of science and engineering applications– Are integrated into a balanced, comprehensive, national cyberinfrastructure environment– Are supported at national, regional, and/or campus levels

• Invest now to prepare for exascale systems that will be available by 2018–2020– Co-design partnerships– Data cyberinfrastructure (networking, disk, and storage) for data-driven science

• Broaden outreach to include industry and new user communities

• Establish a continuing process for soliciting community input on plans for HPC investments
