Chem (Miller) ScaLapack => ESSL, PhiPack 1995 –Tape Robot: Digital Library (Wilensky) –RS6000s: ME (Bogy)

IBM 5/11/99intro5 SUR History (cont) 1996 –Many raw Disks: Tertiary disk project (Patterson) »Museum of Fine Arts –RS6000s: Chem Eng. (Chandler) 1997 –Disk towers: Millennium (CS, Astro/Phys, Civil,...) –G30 SMP: (Yelick, Demmel) –RS6000s: ME, Chem 1998 –SP2: Chem (Head-Miller) –150 WorkPads: EECS PostPC –Disk Tower Supplement: Dlib/DataBase Cluster (Wilensky,Hellerstein) => Almaden looking at wireless infra.

IBM 5/11/99intro6 SUR 1999: Leave the desk behind Servers –host production Ninja Services Mobile pads –smallest fully networked device to break the tethers Emdedded Displays –touch sensitive LCD mounted in the walls Cross Pads –extend the NotPals experience Vision Pads –change the mode of interaction

IBM 5/11/99intro8 Universal Berkeley

IBM 5/11/99intro9 Natural Tides of Innovation Time Integration Innovation Log R Mainframe Minicomputer Personal Computer Workstation Server 2/99

IBM 5/11/99intro10 Away from the “average device” Powerful, personal capabilities from specialized devices –small, highly mobile or embedded in the environment Intelligence + immense storage and processing in the infrastructure Everything connected Laptops, Desktops Devices

IBM 5/11/99intro11 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 3 a : embracing a major part or the greatest portion (as of mankind) b : comprehensively broad and versatile 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 5 : adapted or adjustable to meet varied requirements (as of use, shape, or size)

IBM 5/11/99intro12 1. covering all without limit Internet-Scale Systems Research Group (ISRG) –MASH / BARWAN / MINT »Distributed Interactive Services, mobile networks, SRM, NW simulation –NINJA »Platform Architecture for Scalable, Customizable Internet Services –Iceberg »Computer / Telephony Integration –Millennium »Vast Inter-Cluster Testbed Digital Libraries Billions of Apliances 100 Million Wired Million Scalable Servers

IBM 5/11/99intro13 Millennium Testbed Large-scale testbed (1000 proc, 12 M$) –Cluster of clusters across campus with high-speed network –Extended into the workspaces Ninja architecture allows developers to “Push Services into the Infrastructure” Gigabit Ethernet PDAs Cell Phones Future Devices Wireless Infrastructure Desktop PCs Servers Clusters Massive Cluster

IBM 5/11/99intro14 Core Questions How to make it easy to author services that can provide value to a large fraction of the world? –inktomi serves 20 million users per day! –Preserve distributed innovation in a service-centric world –Ninja: »structured architecture »push services into the infrastructure »composition of services Design principles of systems at world-wide scale?

IBM 5/11/99intro15 2: present or occurring everywhere The Ubiquitous, Pervasive connotation Small devices + protocols are enablers –everyone is building information appliances What is the overall architecture that incorporates these billions of devices? –How are they programmed? –Deeply embedded spontaneous networking. –How do they take on a role in the context of their environment? –How are they managed? –How does authentication, security operate? –Manual override? Crisis? How do we interact with a computationally rich environment?

IBM 5/11/99intro16 Directions Universal Access to Storage as Fundamental Simplifier –Endeavor Oceanic Store (Katz, Kubiatowitz) –Massive Storage Systems (Patterson) Build services that extend down into devices (Ninja) –Keep the hardwork in the infrastructure –Service delivered on a path of proxies –Construct paths automatically Join with TelCo from the start (Iceberg) Resource Mgmt via Comp. Economies Negotiation Architecture (Endeavor) Wildest imagination devices (BSAC) Wide-Area Path

IBM 5/11/99intro17 3. embracing a major part of mankind not just building world-wide services not just connecting every device What fundamentally are the new modes of interaction? –Novel user interfaces »very small formats, very large formats, non-WIMPS –Bridging human differences –Integrated personal and collaborative environments –Harnessing Tacit Information

IBM 5/11/99intro18 5. adapted or adjustable to meet varied requirements Need to write a “program” today that will provide a valuable function to millions of people in execution evironments that don’t yet exist - or haven’t yet been conceived. Need fundamentally fluid software –adapts to the structure of its environment Any size, any shape

IBM 5/11/99intro19 Today’s Plan DARPA Endeavor (Katz) –framework for overall effort and industry collaboration Ninja / Iceberg / Millennium (Joseph) –novel, scalable services Storage Architectures (Patterson) Digital Libraries (Wilensky) HCI (Landay) DISCUSS and DECIDE
