  1. Fourth International Workshop onParallel Programming Models andSystems Software for High-End Computing(P2S2 ‘11)

  2. Organizing Committee • Steering Committee • William Gropp • University of Illinois, • Urbana Champaign • Vijay Saraswat • IBM Research • Program Co-chairs • Pavan Balaji • Argonne National Laboratory • Abhinav Vishnu • Pacific Northwest National Laboratory • Yong Chen • Texas Tech University P2S2 Opening Remarks (09/13/2011)

  3. Workshop Goals • Primary Goal: Consolidating ideas for programming and managing high-end computing systems • Large machines almost always mean complex architectures • Sometimes it means a larger count of existing machines • Oftentimes it means disruptive changes to our current understanding of system architectures • We hope to serve as a venue for researchers to exchange ideas in how the community can build and use the world’s largest systems! P2S2 Opening Remarks (09/13/2011)

  4. Ready or Not, Here it Comes! 10 PFlops in 2011 100 PFlops in 2015 • Expected to have an Exaflop system in 2018-2019 ! P2S2 Opening Remarks (09/13/2011)

  5. Systems Are Already Very Complex Need to Convert System Capacity to System Capability P2S2 Opening Remarks (09/13/2011)

  6. Challenges for Massive Systems • Scalability • Systems with hundreds of thousands of cores exist • We will have a million cores soon • Small performance problems can get brutal at scale ! • Ease of Use (The “Wizard Gap”) • Not everyone is a parallel programming expert • … and yet, everyone wants the best performance • We live in a heterogeneous jungle • Multicore processors, Integrated Accelerator cores, GPUs, FPGAs • Reliability and Maintainability • Failure detection and transparency • Ease of administration P2S2 Opening Remarks (09/13/2011)

  7. Workshop Areas of Interest • Parallel Programming Models and their associated Runtime Systems and other Systems Software as applicable to high-end computing systems • Questions that we are pursuing: • How should the largest machines in the world be programmed? • What runtime systems and other system software is necessary to program and manage these massive systems efficiently and productively? P2S2 Opening Remarks (09/13/2011)

  8. Program Committee: 23 members • Guangming Tan, Chinese Academy of Sciences • Rajeev Thakur, Argonne National Laboratory • VinodTipparaju, Oak Ridge National Laboratory • JesperTraeff, University of Vienna, Europe • BharadwajVeeravalli, National Univ. of Singapore • WeikuanYu, Auburn University • Yunquan Zhang, Chinese Academy of Sciences Ahmad Afsahi, Queen's University George Almasi, IBM Research TaisukeBoku, Tsukuba University Ron Brightwell, Sandia National Laboratory SurendraByna, Lawrence Berkeley National Lab Zhihui Du, Tsinghua University RahulGarg, IBM Research, India TorstenHoefler, Indiana University Zhiyi Huang, University of Otago, New Zealand Hai Jin, Huazhong University of Science and Tech.
