1 Revitalizing High-End Computing – Progress Report July 14, 2004 Dave Nelson (NCO) with thanks to John Grosh (DoD)

2 2 HECRTF – June 10, 2004 Applications of High-End Computing: Big Problems with Big Impacts Weather Prediction Climate Modeling Biology Nano-Science Aeronautics Cryptanalysis Ship Design Nuclear Stockpile Stewardship Astrophysical Simulation

3 3 HECRTF – June 10, 2004 HECRTF Goals l Make high-end computing easier and more productive to use. l Foster the development and innovation of new generations of high-end computing systems and technologies. l Effectively manage and coordinate Federal high- end computing. l Make high-end computing readily available to Federally Agencies that need it to fulfill their missions.

4 4 HECRTF – June 10, 2004 High End Computing Revitalization Plan in a Nutshell ElementsMajor Challenges Addressed R&D l Hardware, software, and systems roadmaps l Basic and applied research, advanced development, engineering and prototypes, and test and evaluation  Research and evaluation systems  Life-cycle software strategy l Improve performance, programmability, usability, and reliability for Agency applications l Provide a range of robust HEC architectures and software technologies to address Agency requirements l Re-establish research pipeline l Ensure healthy research/tech/industry base Resources l Accessibility – Small / Large Agencies & Industry l Availability – Production Computing l Leadership – Largest systems for scientific leadership l Lack of access to HEC resources by small agencies (e.g., NIST) l Increasing demands for HEC exceed resources l Large-scale systems to attack high-priority national problems Procurement l Pilot studies in benchmarking, total cost of ownership, and procurements l Improve efficiencies in procurement for government and industry l Improve evaluation methodologies of HEC systems for procurements and systems designs Note: HEC = High End Computing

5 5 HECRTF – June 10, 2004 High End Computing University Research Activity l Coordination Solicitations  NSF, DOE/Office of Science, DARPA  Working group chair: Candy Culhane (NSA) l ITRD Portal  http://www.itrd.gov/hecrtf-outreach/hec- ura/index.html http://www.itrd.gov/hecrtf-outreach/hec- ura/index.html HEC R&D AreaLead Agency Operating systemsDOE/Office of Science Languages, compilers, and libraries National Science Foundation

6 6 HECRTF – June 10, 2004 System Performance Assessment Pilot l Purpose:  Better match codes to existing architectures and machines  Inform procurements  Validate code performance and system performance  Guide design of future architectures and systems l Status:  Lead: Bryan Biegle of NASA/Ames  Initial workshop  Substantial interest

7 7 HECRTF – June 10, 2004 Computational Requirements (Factors of 10) Time (years) Transition of Solving Important Problems (1) Yesterday’s unsolvable problem Leading Capability Systems Capacity Systems (2) Will be today’s problem solvable only on the world’s largest available systems (4) … and someday solved on your laptop (3) Will be tomorrow’s problem easily solvable on a “regular” HPC system 5 to 10 years High-end computing enables US to solve “unsolvable” problems first. Note: Improvements due to both hardware and algorithms.

8 8 HECRTF – June 10, 2004 Capability, Capacity and Accessibility l DOE/SC selected ORNL for substantial system  Not quite Leadership Class in sense of HECRTF  Discussions beginning regarding management and usage policies l NASA will be making announcement soon
