Manchester Computing Supercomputing, Visualization & e-Science Michael Daw 25 th August 2003 NORDUnet Network Conference Reykjavik, Iceland Access Grid The Future of Advanced Collaboration?
Supercomputing, Visualization & e-Science2 Contents What is Access Grid? History of Access Grid Current developments Future developments Videoconferencing Report SC Global
Supercomputing, Visualization & e-Science3 Typical Views of Access Grid ETF Management MeetingSeminar SC Global WorkshopPerformance Art
Supercomputing, Visualization & e-Science4 What is Access Grid? (1) Large-scale display – typically a whole wall Multiple video streams from each site Natural, full-duplex audio with echo cancellation An “Advanced Collaboration Environment” Uses IP multicast for video/audio Open Source software; commodity equipment Usually!
Supercomputing, Visualization & e-Science5 What is Access Grid? (2) Virtual collaborative spaces – Virtual Venues Places to share: –Video –Audio –Data –Applications Virtual Organisations have their own Virtual Venues
Supercomputing, Visualization & e-Science6 Access Grid History November 1998 – Access Grid born at Argonne National Lab First event – Chautauqua ‘99 August 2001 – UK gets first AG node @ Manchester November 2001 – SC Global 2001 (Denver) May 2003 – AG2 November 2003 – SC Global 2003 (Phoenix)
Supercomputing, Visualization & e-Science7 Number of Access Grid Nodes Feb 2003 – 5 out of 7 continents; 17 countries; 39 US states
Supercomputing, Visualization & e-Science8 Scheduled Access Grid Events But how many unscheduled?
Supercomputing, Visualization & e-Science9 Current Developments – AG2 AG1 = proof-of-concept prototype AG2: Integrate with Grid technologies (e.g. X.509 certificates for authentication) Secure environment Robust, extensible framework Improved network features Services architecture
Supercomputing, Visualization & e-Science10 Future Developments Improved video Improved audio Easier operation Easier sharing of data Automated failover Support of different bandwidth capabilities
Supercomputing, Visualization & e-Science11 Videoconferencing Report Oct 2002 – publication of “Multi-Site Videoconferencing for the UK e-Science Programme” http://www.nesc.ac.uk/technical_papers/UKeS-2002- 04.html http://www.nesc.ac.uk/technical_papers/UKeS-2002- 04.html Comparison between Access Grid, H.323/H.320, VRVS, Non-Studio Based Videoconferencing Human Factors Interoperability Data & Application Sharing
Supercomputing, Visualization & e-Science12 Main Recommendations 1.Create an e-Science advanced collaborative environments R&D effort 2.Formalise Access Grid support 3.Enable full interoperability between different technologies 4.Deploy multicast bridge(s) 5.Investigate improvements for multi-site booking systems
Supercomputing, Visualization & e-Science13 SC Global 2001 SC Global 2001 – “World’s First Truly Distributed Conference” 6 out of 7 continents
Supercomputing, Visualization & e-Science14 SC Global 2003 Built on AG2 technology and distributed Tech Hubs Events include: –Tribal Virtual Network –Grid & Web Services towards Collaborative Visualization –Virtual Design in Engineering –Collaborative Art 18-21 November At Phoenix & on the Network! http://www.scglobal.org http://www.scglobal.org
