3. Physical Connectivity Millennium

4. Associated Commitments • Intel provides 6 M$ in equipment • Sun provides all Solaris x86 software • Microsoft provides all NT software • Campus provides staff to support the core infrastructure, networking • CS will try to raise funds for the network and campus cluster infrastructure • Departments provide 1/2 of system admin for own side and 20 K$ for group cluster • racks, network, software, ... Millennium

5. Where are we? • Evolving Vision => SimMillennium • Hardware deployment • Software availability • Cluster Environment • Grants • Networking Millennium

6. The Vision • To work, think, and study in a computationally rich environment with deep information stores and powerful services • test ideas through simulation • explore and investigate data and information • share, manipulate, and interact through natural actions • Organized in a manner consistent with the University setting Millennium

7. SimMillennium Project Goals • Enable major advances in Computational Science and Engineering • Simulation, Modeling, and Information Processing becoming ubiquitous • Explore novel design techniques for large, complex systems • Fundamental Computer Science problems ahead are problems of scale • Develop fundamentally better ways of assimilating and interactingwith large volumes of information • and with each other • Explore emerging technologies • networking, OS, devices Millennium

8. Components of the Effort • Community • Cluster-based Resources • Connectivity • User Interaction • Computational Economics Millennium

9. NSF investment: Cluster Network • Transforms large collection of individual resources into a powerful system • can be focus on a problem • High Bandwidth • scales with the number of processors (Gb/s per proc) • Low Latency • Low Overhead • Low Cost • Simple and Flexible • Almost no errors • Low Risk • Today: Myrinet Millennium

10. NSF Investment: Inter-cluster network • Gigabit Ethernet connecting group clusters and campus cluster • Bay Networks provides 70% discount • Campus provides fiber plant, maintenance, and staff Millennium

11. NSF Investment: UI Technology • Two Projection Table • large field of view in horizontal (or vertical) orientation • Phantom Haptic Interface • 3D force feedback • Motion Tracker • untethered position • 3D Shutter Glasses • low cost visualization Millennium

12. User Interaction Research Agenda • Expand access to 3D visualization • Explore any data anywhere • Ease development • Develop lab-bench metaphor for Viz • two hands, physical icons • Fast prototyping and exchange through Informal Interfaces • sketching • Dealing with large volumes of information • lenses, brushing and linking • 3D collaboration and interaction Millennium

13. Computational Economy • How is this vast, integrated pool of resources managed? • Traditional system approach: empower global OS to provide “optimal” allocation to blind applications • predefined metric, tuned to fixed workload • ignores the inherent adaptation of demand • Computer Center • charge => director-to-user feedback according to cost • Economic view: decentralized allocation according to perceived value • pricing => user-to-user feedback • compatible niches,sense of control, cooperation • idea has been around, why now? Millennium

14. NSF Investment: Staff Support • Provide enabling technology and let it evolve • monitoring, enforcement • exchange • negotiation tools • Integrate it into users enviroment • Tools and measurements to determine effectiveness Millennium

15. Integrated Research Agenda • Advance the State of Computational Science and Engineering • immerse a community in a computationally rich environment with the right tools: algorithms, programming & system support • Path to exploiting novel techniques and technology • Explore design techniques for robust large-scale distributed systems • economic (or ecologic) approach • Explore new ways of interacting with information • large paste-ups, two hands, sketching, 3D collaboration • Investigate new technology • SMP nodes, gigabit Ethernet, SANs, VIA • NT, dCOM, Java beans, directory services • workbench displays, 3D icons, haptics, position sensors Millennium

16. Perspective • Highly leveraged investment in a large scale infrastructure for studying problems of scale • Deep commitment across the campus • Sense of ownership and participation • Rich research agenda Millennium

17. Nuts and Bolts Millennium

18. Current Environment • All projects have servers and several desktops • last few in current shipment • millennium.berkeley.edu domain established • solaris/x86 shared servers with 60GB disks • www.millennium.berkeley.edu, MM.millennium.berkeley.edu • imap, ... • solaris/x86 sww served from CS servers • NT domain server with 60 GB disks • MMNT.millennium.berkeley.edu • exchange, file, ... • First cluster ready for use • NSF SimMillennium grant to cover network • Two of three Millennium staff hired Millennium
