  1. Connecting the Invisible Extremes of Computing David Culler http://www.cs.berkeley.edu/~culler U.C. Berkeley Summer Inst. on Invisible Computing July, 1999.

  2. What I do • Parallel Computer Architecture • Lean Operating Systems • Novel Programming Environments => Lean, Fast & Flexible Communication Primitives • Active Messages => Design of Federated Systems of Systems • NOW (Network of Workstation) • Current Projects • Millennium: Campus-wide Cluster-of-Clusters Testbed • Ninja: Proactive Infrastructure Services • Endeavour: Information Utility based on Fluid Software • UCB (universal computing @ berkeley) invisible computing

  3. Scalable Infrastructure • highly available • persistent state (safe) • databases, agents • service programming environment Service Path • Ubiquitous Devices • billions • sensors / actuators • PDAs / smartphones / PCs • heterogeneous Expanding the Spectrum • Desktops • max out at few 100M • in your face • connected to the infrastructure invisible computing

  4. Issues Converge at the Extremes • Powerful Services on “Small” Devices • massive computing and storage in the infrastructure • active adaptation of form and content “on the way” • Lean, Flexible Communication Building-Blocks • simplicity is the key to efficiency • Federated System of Systems • Availability, Automatic Configuration and Management • Plug it all together and have it DWYM! invisible computing

  5. Your PDA connects to the local infrastructure and asks it to build a custom GUI • Next, your PDA asks the infrastructure for a path out to your personal information space, where agents are processing your e-mail, v-mail, faxes, and pages You have complete, secure, optimized access to local devices and your private resources Ninja Vision • You walk into a room invisible computing

  6. Open Clients Clients Clients Clients Servers Clients Clients Servers Servers The Internet Push Services into an Active Infrastructure Infrastructure Services => enable Distributed Innovation of Scalable, Avail. Services invisible computing

  7. Massive Cluster Clusters Servers Wireless Desktop PCs Gigabit Ethernet PDAs Future Devices Millennium: Large-Scale Testbed • Campus-wide cluster-of-clusters extended down • Management by Services • push monitoring service into nodes • Resource allocation by market services • banks, brokers, merchants Cell Phones invisible computing

  8. Endeavour Vision/Objective • Enhancing human understanding through information technology • Make it dramatically more convenient for people to interact with information, devices, and other people • Supported by a “planetary-scale” Information Utility • Stress tested by challenging applications in decision making and learning • New methodologies for design, construction, and administration of systems of unprecedented scale and complexity • Figure of merit: how effectively we amplify and leverage human intellect • A pervasive Information Utility, based on “fluid systems technology” to enable new approaches for problem solving & learning invisible computing

  9. Information Devices Beyond desktop computers to MEMS-sensors/actuators with capture/display to yield enhanced activity spaces InformationUtility InformationApplications High Speed/Collaborative Decision Making and Learning Augmented “Smart” Spaces: Rooms and Vehicles Design Methodology User-centric Design withHW/SW Co-design; Formal methods for safe and trustworthy decomposable and reusable components “Fluid”, Network-Centric System Software Partitioning and management of state between soft and persistent state Data processing placement and movement Component discovery and negotiation Flexible capture, self-organization, and re-use of information Proposed Approach invisible computing

  10. What I’m looking for in an Architecture for Billions of Devices • Reservoirs, Flows, Self-Checking Simplifiers invisible computing

  11. Natural Tides of Innovation Innovation ?? Integration Personal Computer Workstation Server Log R Minicomputer Mainframe 2/99 Time invisible computing

  12. universal Function: adjective 1 : including or covering all or a whole collectively or distributively without limit or exception 2 a : present or occurring everywhere b : existent or operative everywhere or under all conditions <universal cultural patterns> 3 a : embracing a major part or the greatest portion (as of mankind) <a universal state> <universal practices> b : comprehensively broad and versatile <a universal genius> 4 a : affirming or denying something of all members of a class or of all values of a variable b : denoting every member of a class <a universal term> 5 : adapted or adjustable to meet varied requirements (as of use, shape, or size) invisible computing
