The Access Grid Ivan R. Judson 5/25/2004

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.

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

MSR SciData Workshop May 25, 2004 The Virtual Venues Client

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

MSR SciData Workshop May 25, 2004 Architectural Overview

MSR SciData Workshop May 25, 2004 History and Growth

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!

MSR SciData Workshop May 25, 2004 Application Deployments Integration with various user communities –Existing AG Community 1000 public private: 1000 users –Fusion Collaboration > 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

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

MSR SciData Workshop May 25, 2004 AGTk 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

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

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
