The Access Grid Ivan R. Judson judson@mcs.anl.gov 5/25/2004 Slide 2 MSR SciData Workshop May 25, 2004 Access Grid Vision To create virtual spaces where distributed people can work together. Challenges: Globally Distributed Participants Distributed Resources: Computational, Storage, Networks, and People Coordination, Scheduling, Trust Heterogeneous Collaboration Resources Solution: Deploy a set of Collaboration Resources to serve as the platform for building the rest. Slide 3 MSR SciData Workshop May 25, 2004 Virtual Venues Client What can be done: Sharing Data Shared Applications Integration with existing Scheduling software Applications: Distributed PowerPoint Shared Web browser Whiteboard Shared Desktop Tool Shared Visualization Tools Integrate legacy workflows APS SER-CAT Beam line Controls Data Processing Data Analysis Archiving/Reporting Fusion Collaboratory Collaborative Control Room Atmospheric Science Shared Data Visualization Slide 4 MSR SciData Workshop May 25, 2004 The Virtual Venues Client Slide 5 MSR SciData Workshop May 25, 2004 Wide of Client Platforms Supported Hardware 1.Advanced Node Tiled Display, Multiple Video Streams, Localized Audio 2.Room Node Shared Display, Multiple Video Streams, Single Audio Stream 3.Desktop Node Desktop Monitor, Multiple Video Streams, Single Audio Stream 4.Laptop Node Laptop Display, Single Video Stream, Single Audio Stream 5.Minimal Node Compact Display, Single Video Stream, Single Audio Stream Supported Platforms 1.Windows XP/2000 2.Linux variants (RedHat, Slackware, Fedora, Debian, ) 3.Mac OS X (in the future) Slide 6 MSR SciData Workshop May 25, 2004 Access Grid Security Public Key Infrastructure (PKI) based security. Each user, server, and service has an identity cert Communications use SSL (via Globus Toolkit) SSL provides Mutual Authentication (each pair of peers knows the identity of the other) Confidentiality Authorization is difficult, so we make it easier Slide 7 MSR SciData Workshop May 25, 2004 Architectural Overview Slide 8 MSR SciData Workshop May 25, 2004 History and Growth Slide 9 MSR SciData Workshop May 25, 2004 Crossroads Up to now weve been serving the AG community (ourselves) exclusively The introduction of this technology can revolutionize science, deploying into new communities will change the social landscape. Its time for the Access Grid to grow up. So how are we going to get there? Become a service organization? Abandon the software and move on? Adapt and evolve! Slide 10 MSR SciData Workshop May 25, 2004 Application Deployments Integration with various user communities Existing AG Community 1000 public + 300 private: 1000 users Fusion Collaboration > 1000 (@ 40 institutions) ANL Advanced Photon Source CAT Teams 4000 users Center for Learning and Multimodal Communication ABC Collaboration (Surgical Teaching) Introduces new requirements and refinements of existing requirements Increases User base Slide 11 MSR SciData Workshop May 25, 2004 Toolkit Research Directions Deeper integration with Grid Computing Compute Resources, Data Resources Publish/Subscribe Service Models Peer to Peer Applications and Services Investigate much more interesting node solutions Extending Security Work More Authentication Solutions More Authorization Solutions Engage new communities Slide 12 MSR SciData Workshop May 25, 2004 AGTk 2.2 3.0 Network Services Example Services Node Management User/Venue Services Chat Improvements Firewall optimizations Port to OS X Community Service Operators Interface New Node Services High Quality Video Display (with layout) Camera Control Interoperability SOAP (ZSI, Apache) Language (java, C/C++) Grid Data Integration Slide 13 MSR SciData Workshop May 25, 2004 Roadmap II: AGTk 3.0 ??? Advanced Node Configurations Support for more Active Spaces Better audio environments, high quality video Better media synchronization Integrated instruments (telescopes, beamlines, ) This will cost: Bandwidth Minimal Node Configurations Handhelds Set-top box configurations Advanced Collaboration Services Stream processing, modifying Data mining from Streams This will cost: Latency Slide 14 MSR SciData Workshop May 25, 2004 Roadmap II: AGTk 3.0 ??? Grid Compute Resources Authentication Flexibility Certificate Authority Services Application Integration (for specific targets) Workflow Support Application Hosting Services Slide 15 MSR SciData Workshop May 25, 2004 More Information The Access Grid Project http://www.accessgrid.org/ http://www.accessgrid.org/ The Access Grid Toolkit http://www.mcs.anl.gov/fl/research/accessgrid/ http://www.mcs.anl.gov/fl/research/accessgrid/ Slide 16 MSR SciData Workshop May 25, 2004 Credits This work is supported by: The Department of Energy, Office of Science The National Science Foundation, and Microsoft Research
