  2. Objectives • Clusters are being targeted for high-end computing as well as high-performance servers • Requires • High-performance communication and I/O subsystems • Low overhead programming environment support • Support for QoS for emerging applications • Study of the impact of emerging networking technologies and standards (VIA, InfiniBand) • Goals: Bring together researchers and practitioners from academia, industry, research labs and national labs to discuss solutions as well as future trends for designing scalable, high-performance, and cost-effective communication and I/O architectures for clusters

  3. Organization • Started in 2001 • Takes place in conjunction with Int’l Parallel and Distributed Processing Symposium (IPDPS) • CAC ’01 (IPDPS ’01) in San Francisco, April 2001 • CAC ’02 (IPDPS ’02) in Ft. Lauderdale, April 2002 • CAC ’03 (IPDPS ’03) in Nice, France, April 2003 • Co-organized by • D. K. Panda (OSU) • Jose Duato (Univ. of Valencia, Spain) • Craig Stunkel (IBM TJ Watson)

  4. Organization • Follow-up to the Communication and Architectural Support for Network-Based Parallel Computing (CANPC) Workshops, held in conjunction with HPCA conference from 1997-2000 • Focuses on interaction between presenters and audience • Thanks to many people in this room • PC members • Keynote Speakers • Authors • Session Chairs • Panel Moderators • Panelists • Please do not blame me if your paper was not accepted • We (organizers) simply followed the recommendations by PC members

  5. CAC ‘01 • 14 papers out of 24 • Grouped along four sessions • Low-level Messaging • Interconnection and Communication • Switch/Router and NIC Support • Network Services and Communication • Keynote Talk by Prof. Thomas Sterling Commodity Clusters: The Third Wave for High Performance Computing • Focused on multiple issues related to cluster computing • Emphasized on next generation cluster computing in space (using computers in satellites)

  6. CAC ’01 (Cont’d) • Panel Session InfiniBand: The de-facto standard for system and local area networks or just a scalable replacement for PCI Buses? • Moderator: Timothy Pinkston (USC) • Panelists: • Jose Duato (Univ. of Valencia, Spain) • Michael Krause (HP) • Irving Robinson (Intel) • Thomas Sterling (Caltech and JPL) • Madhu Talluri (Sun) • Alan Benner (IBM) • Six papers and a copy of the panel report (after going through another round of review process) have been selected to appear in a special issue of Cluster Computing journal, April 2003 • Was attended by around 70-80 people

  7. CAC ’02 • 11 papers out of 19 (less submissions due to 9/11) • Grouped along four sessions • Routing and Switching • Remote Memory Communication • I/O and NIC Support • InfiniBand • Keynote Talk by Prof. Tony Skjellum Explicit Parallel Programming with Message Passing Interfaces: Legacy, Longevity, Optimizability, Evolvability • Focused on multiple issues related to past and current development of MPI • Emphasized on multiple aspects of optimizing MPI implementations

  8. CAC ’02 (Cont’d) • Panel Session Cluster Interconnects Crystal Ball: Which will win in 2006? • Moderator: Craig Stunkel (IBM TJ Watson) • Panelists: • David Addision (Quadrics) • Kevin Dierling (Mellanox) • Patrick Geoffray (Myricom) • Shubu Mukherjee (Intel) • Renato J. Recio (IBM) • Was also attended by around 70-80 people

  9. CAC ’03 • 13 papers out of 37 • Grouped along five sessions • Communications Hardware • Network Interfaces and Collective Communication • Communication Libraries • System Services • Performance Evaluation • Keynote Talk by Prof. Dan Reed Clusters: Challenges and Opportunities • Panel session Top 3 technologies that are limiting cluster interconnects • Moderator: Ron Brightwell (Sandia) • Panelists: being decided
