History
  • November 1998
  • Futures Laboratory Group at Argonne National
    Laboratory creates the Access Grid
    1
  • 1999
  • EVL begins participation in the Access Grid
    community 2
  • Today
  • 104 Access Grid nodes nationally and
    internationally
  • Some sites have multiple Access Grid nodes
    (including EVL)

3
Nodes
  • Spaces for people
  • Specially designed physical audio-visual spaces
  • Support interactions with people locally and
    across the network
  • Additional high-end video and audio equipment
  • Create a favorable user experience

4
Nodes
  • Spaces for people
  • Have many visual displays to allow for viewing
    many video streams and other applications
  • Types of furniture and furniture arrangement are
    important

5
Node Components
  • Required hardware and software
  • Video conferencing software
  • Microphones
  • Cameras
  • Computers
  • And more

Venues
  • Nodes meet in virtual spaces
  • Junction of interconnected video and audio
    streams
  • Computing resources enabling human interaction
  • Future Computational grid applications/data
  • Enables a variety of collaborations
  • Large-scale distributed meetings (conferences)
  • Work sessions
  • Seminars, lectures, training
  • Any collaboration benefiting from live video and
    audio
  • 3

8
Future
  • Human interface to the grid
  • Computing resources are organized into the grid
  • Access Grid enables human communication over the
    grid

Version 2.0 Architecture
  • 5

10
Community
  • Industry
  • Boeing, Ford Motor Company, Johnson Johnson,
    Microsoft, Motorola
  • Educational and Research Institutions
  • 75 nationwide sites
  • Private, public, and government-funded
    institutions
  • 15 international sites
  • Australia, Brazil, Canada, China, Germany, Italy,
    Japan, Korea, Netherlands, United Kingdom
  • 6

11
Meetings
  • Sizes of meetings
  • One or two other sites
  • Small group of sites (primary design point)
  • Large group of sites
  • Sharing of applications and data helps create
    collaborative work sessions

12
Videoconferencing
  • One or two other sites
  • CAVE application (YG) seminar to plan an art
    installation
  • University at Buffalo, Indiana University
  • Informal meetings, discussions
  • Technical help for fixing Access Grid node
    problems

13
Videoconferencing
  • Small group of sites
  • Virtual News Conference Academic Excellence for
    All Urban Students (EVL hosted 15 attendees from
    the CPS system)
  • NSFs Urban Systemic Initiative improved math and
    science scores

14
Videoconferencing
  • Small group of sites
  • NSF CISE Grand Challenges in e-Science Workshop
    (EVL hosted conference had 30 attendees)
  • Discussions about the utilization of high
    performance computing will help advance science
    and engineering

10

15
Videoconferencing
  • Large group of sites
  • Chatauqua 1999, 2000 (EVL presented VR work,
    Chatauqua 2000)
  • The first large scale Access Grid meeting ever
    conducted.
  • SC Global 2001 (EVL attended)
  • Live from certain Denver venues of Supercomputing
    2001
  • Remote international and national sites in
    attendance

16
Videoconferencing
  • EVL applications
  • Videotape on video stream (no audio)
  • Integration of Polycom into the Access Grid
  • Overlays
  • Art

17
Remote Computer Access
  • Virtual Network Computing (VNC)
  • Created by ATT Laboratories
  • Displays the desktop of the computer
  • Can remotely control a computer
  • Advantages
  • High resolution still images
  • Better than viewing compressed video streams of a
    still image

18
Shared Slide Presentation
  • DPPT (Distributed PowerPoint)
  • Created by Argonne National Laboratory
  • Uses MS PowerPoint plus additional software
  • Remote site commands local slides changes
  • Disadvantages
  • Animations cannot be run
  • Audience cannot see a remote mouse pointer
  • RPPT (Remote PowerPoint)
  • Overcomes disadvantages of DPPT

19
Video-On-Demand
  • Voyager
  • Developed by Argonne National Laboratory
  • Allows the recording and playback of
    videoconferences
  • Used by EVL to record students masters thesis
    defense
  • Future improvements
  • Synchronized recording and playback of data
    streams
  • Data from scientific instrumentation, audio, and
    video

20
Continuum
  • Group-to-Group Collaboration
  • Distributed, collaborative work environment
  • Advanced collaboration, computation, and
    visualization technologies
  • Access Grid, AGAVE, Access Grid-to-Go and VVP,
    AccessBot, TeraVision, tiled high-resolution
    displays
  • Investigators
  • Dr. Jason Leigh, Kyoung Park, Atul Nayak, Mitch
    Theys
