America's Next Generation Supercomputer: The Exascale Challenge, Hearing Before the Subcommittee on Energy of the Committee on Science, Space, and Technology, House of Representatives, One Hundred Thirteenth Congress, First Session, May 22, 2013   [open pdf - 5MB]

This is the May 22, 2013 Hearing, "America's Next Generation Supercomputer: the Exascale Challenge," before the Subcommittee on Energy of the House Committee on Science, Space, and Technology. From the opening statement of Cynthia Lummis: "The development and expanded availability of supercomputers has enabled society to push the frontiers of nearly every scientific discipline, and accelerate applications of that science in countless fields. [...] These advancements ultimately trace back to Federal investments in basic research that provided the foundation for most of today's computing technologies. [...] The Department of Energy, led by the Advanced Scientific Computing Research program, plays a critical role in driving these computing technology breakthroughs. DOE supports world-class computational science facilities, such as the National Energy Research Scientific Computing Center. Additionally, DOE funds cutting-edge applied mathematics research and next-generation networking activities. DOE's next major computing challenge, constructing an ''exascale'' computer system that is a thousand times faster than current world-leading supercomputers, may be the most daunting. Key scientific and technical obstacles associated with the architecture and energy efficiency of an exascale system must be overcome, and an immense amount of resources and effort will be required. [...] We need to ensure DOE efforts to develop an exascale system can be undertaken in concert with other foundational advanced scientific computing activities." Statements, letters, and materials submitted for the record include those of the following: Cynthia Lummis, Randy Hultgren, Eric Swalwell, Roscoe Giles, Rick Stevens, Dona Crawford, and Daniel Reed.
