  1. ISRG and the Post-PC Era David Culler U.C. Berkeley ISRG Retreat Jan, 1999.

  2. Why is Internet-Scale Systems Research Concerned with Small “Post-PC” Devices? ISRG Retreat

  3. SmallDevices billions The Emerging Platform Pyramid SuperComputers SuperServers 100s Departmental Servers 10Ks Workstations Workstations < Million Personal Computers 100 millions ISRG Retreat

  4. Future Internet-Scale Systems • ~10 Billion of Information Appliances • ~100 Million of Stationary Computers • ~Million Scalable Servers ISRG Retreat

  5. Natural Convergence • “Internet-Scale” => system reaches “everywhere” • small devices will be what is “wherever” • Small devices provide powerful services • because the intelligence is in the infrastructure • The breakthrough ahead is pervasive devices + communication • Services, adaptation, access, customization, simplicity, efficiency, ... ISRG Retreat

  6. Seeds sewn in many projects • Infopad, Wingman, Mediaboard, Notepals, ... • Ninja - platform architecture • powerful services on small devices through a powerful infrastructure • Iceberg - integration of computing and telephony • Notepals - new user interfaces • IRAM - high performance multimedia at low power • Aetherstore - the data is out there • Demos around you... ISRG Retreat

  7. A Radical Experiment • What we need is not a new research project • It is a new “computing culture” ISRG Retreat

  8. Game Plan (Oct 1998) Build a department-wide, universal wireless PDA infrastructure • Initial Seed: 150+ IBM workpads + lots of cradles + IR + ??? • Running UI classes on them • Bring in all interested 1st year CS grads • Fill out based on interest, talent and availability • next generation wider and better => “ask a good question and get yours” seminar ISRG Retreat

  9. Fall’98 Project Excerpts (see posters) • E-Commerce and Security • Pay-Per-Use Services on the Palm Computing Platform (Mike Chen, Andrew Geweke) • Secure Email Infrastructure for PDAs (Hoon Kang, Rob von Behren) • SyncAnywhere - Secure Network HotSync (Mike Chen, Helen Wang) • Groupware • Kiretsu - Ninja Instant Messaging Service (Matt Welsh, Steve Gribble) • The MASH MediaPad - Shared Electronic Whiteboard for the PalmPilot (Yatin Chawathe) • NotePals - Lightweight Meeting Support Using PDAs (Richard Davis) • OSKI - Open Shared Kalendaring Infrastructure (Jason Hong, Brad Morrey, Mark Newman) • OS and Communications • PalmRouter - Networking Sporadically Connected Devices (Andras Ferencz, Robert Szewczyk) • Numerous Architecture Studies • CS160 UI Projects (see James Landay talk) • Ink Chat, Nutrition/Excercise Tracker, Rendezvous - Meeting Scheduler ISRG Retreat

  10. Some Lessons • Communication is enabling • Virtual Environment really is a good thing • Devices connect “into the infrastructure” • Network HotSync, groupware, centralized e-mail => Need lean, clean communication substrate • Much room for improvement in devices • Palm III (WorkPad) is too slow… • adaptation involves trading cycles for bandwidth and interoperability ISRG Retreat

  11. Lessons… • Development effort is the limiting factor • OSKI: 1 person for infrastructure, 2 for WorkPad • Debugging is particularly hard => need complete system simulation environment • “User Service” is fundamental • not just profile and customization info • routing point for security • Surprising similarities with the “infrastructure problem” ISRG Retreat

  12. Phase 2 Plan: Real Users • Deploy some real WorkPad services • Secure e-mail • Network HotSync • Group Calendar • Widespread use of at least one service • more than 50 users? • highly available/reliable ISRG Retreat

  13. Historical Perspective • New eras of computing start when the previous era is so strong it is hard to imagine that things could be different • mainframe -> mini • mini -> workstation -> PC • PC -> ??? • It is always smaller than what came before. • Most think of the new technology as “just a toy” • The new dominant use was almost completely absent before. • So where are we headed in the post-PC era?
