Presentation Transcript

  1. Sandia is a multiprogram laboratory operated by Sandia Corporation, a Lockheed Martin Company, for the United States Department of Energy's National Nuclear Security Administration under Contract DE-AC04-94AL85000.

  2. CSRI Overview

  3. Computer Science Research Institute • Goals: • Collaborative computer science research • Strong Sandia participating in research community • Impact on national security problems • Recruiting • A “co-laboratory” for computer science research • Activities • Collaborative projects • Student and faculty programs • Workshops

  4. CSRI Leaders • David Womble (1410), Director, CSRI • S. Scott Collis (1414), Executive Manager, CSRI • Executive Board: • Heidi Ammerlahn (8962) • Neil Pundit (1423) • Martin Pilch (1221) • Prof. Danny Sorensen, Comput’l & Applied Math, Rice University • Prof. Deepak Kapur, Chairman Comp. Sci., UNM • Deanna Ceballos, CSRI Administrator • Bernadette Watts, CSRI Administrator

  5. Opportunities for Collaborations • Faculty sabbaticals lasting between a semester and a year, • Summer faculty positions, • Graduate fellowships through the NPSC and HPCS (Krell Institute) programs, • Summer student positions, • Technical visits of lengths between one week and three months, • Post-doctoral positions lasting up to two years, • Conference sponsorships, • A CSRI colloquium series, • Visits by laboratory staff to universities.

  6. Thanks • CSRI: • David Womble, Scott Collis. • Deanna Ceballos, Bernadette Watts • Organizing: • Doug Kothe, Trey White, Ricky Kendall • Doug Doerfler, Carter Edwards, Alan Williams.

  7. Workshop Overview

  8. Background & Motivation • MPI-only: • Present: Foundation for scalable applications. • Future: Part of the answer, but not the whole? • Why not the whole: • Near-term: • Multicore nodes: homo/heterogeneous. • MPI+something, but what? • Long-term: Near-term + • Core types, counts and organization. • Memory organization. • New programming models. • Bottom line: How do we develop next-generation scalable applications?

  9. Workshop Goals • Understand the limitations of MPI as the scalable API for future applications. • Identify complementary approaches or replacements, and discuss strategies for transitioning. • Identify algorithmic challenges and directions to enable scalable applications.

  10. Subgroups • Four subgroups: • Applications. • Libraries. • Programming Environments. • Architectures. • Each subgroup has: • Lead • Liaison from each of the other three subgroups. • Responsibilities are: • Lead: Lead subgroup discussion, assign writers/presenters, bring subgroup to consensus. • Liaison: Act as liaison to subgroup in case questions arise.

  11. Subgroup Assignments All others self-assign to subgroups

  12. Key Questions: Scrum-inspired Scrum and XP from the trenches, Henrik Kniberg

  13. 39 Questions • Sent by email this morning. • Broken down by workshop goal, and others. • In subgroups vote on • Priority: • Which are most important to your subgroup. • Which should be answered by other subgroups (next round). • What additional questions should be added. • Choice: • Pick number of questions you think you can answer in allotted time. • Adjust number, as needed, next time.

  14. Workshop Objectives Goals • Understand the limitations of MPI as the scalable API for future applications. • Identify complementary approaches or replacements, and discuss strategies for transitioning. • Identify algorithmic challenges and directions to enable scalable applications. • Address workshopgoals as best wecan via key questions. • As questions resolve,assign writers (majority,minority as needed). • As issues are identified as outside workshop scope, assign writer. • Your questions get answered, or issues clarified. • Product: Final workshop report for wide dissemination. • Ultimate: See paths to next-generation scalable apps.

  15. Miscellaneous • Workshop atmosphere: • Structure intended to stimulate conversation. • Not stifle it. • Flexibility is possible. • Introductions…
