Access Grid The Future of Advanced Collaboration? Michael Daw 25th August 2003 NORDUnet Network Conference Reykjavik, Iceland
Contents • What is Access Grid? • History of Access Grid • Current developments • Future developments • Videoconferencing Report • SC Global Supercomputing, Visualization & e-Science
ETF Management Meeting Seminar Typical Views of Access Grid Seminar SC Global Workshop Performance Art Supercomputing, Visualization & e-Science
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-Science
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-Science
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-Science
Number of Access Grid Nodes • Feb 2003 – 5 out of 7 continents; 17 countries; 39 US states Supercomputing, Visualization & e-Science
Scheduled Access Grid Events • But how many unscheduled? Supercomputing, Visualization & e-Science
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-Science
Future Developments • Improved video • Improved audio • Easier operation • Easier sharing of data • Automated failover • Support of different bandwidth capabilities Supercomputing, Visualization & e-Science
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 • Comparison between Access Grid, H.323/H.320, VRVS, Non-Studio Based Videoconferencing • Human Factors • Interoperability • Data & Application Sharing Supercomputing, Visualization & e-Science
Main Recommendations • Create an e-Science advanced collaborative environments R&D effort • Formalise Access Grid support • Enable full interoperability between different technologies • Deploy multicast bridge(s) • Investigate improvements for multi-site booking systems Supercomputing, Visualization & e-Science
SC Global 2001 • SC Global 2001 – “World’s First Truly Distributed Conference” • 6 out of 7 continents Supercomputing, Visualization & e-Science
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 Supercomputing, Visualization & e-Science
