  1. WestGrid Collaboration and Visualization Brian Corrie Collaboration and Visualization Coordinator WestGrid/SFU

  2. Overview • What is WestGrid? • WestGrid Collaboration and Visualization • Integrating visualization services into AG AG Retreat, June 9 – 11, 2004

  3. What is WestGrid? AG Retreat, June 9 – 11, 2004

  4. WestGrid Grid Philosophy • Provide computational resources to the research community in Western Canada • HPC, data storage, collaboration, visualization • Advanced networking • Provide “seamless” access to the resources through advanced networking and grid technologies • Promote the use of “robust” Grid Tools in place of traditional alternatives • Don’t impose the use of Grid Tools on users AG Retreat, June 9 – 11, 2004

  5. WestGrid Grid Philosophy • Provide a range of computational resources to the Western Canada (and national) community • Provide “seamless” access to the resources through advanced networking • Promote the use of Grid technologies to user/projects that can benefit from them • Encourage the use of “robust” grid tools in place of traditional alternatives • Don’t impose the use of grid tools on users that don’t need them or that already have a good process in place • Deployment of Globus at all sites • GSI based single sign on, gatekeepers for scheduling, meta-schedulers AG Retreat, June 9 – 11, 2004

  6. WestGrid HPC • Large shared memory (UoA) • 256 Processor SGI Origin, 6 smaller Origin servers (8 to 64 processors) • Large cluster (UBC) • 1008 processor IBM blade server • Tightly coupled message passing (UoC) • 144 processor HP SC45 • Storage server (SFU) • 25 TB disk, 135 TB on-line tape • Visualization server (SFU) • 20 processor, 8 pipe SGI Ultimate Vision AG Retreat, June 9 – 11, 2004

  7. WestGrid Networking • HPC/storage sites connected by WAN • Layer-2, gigabit-per-second • Appears as a local subnet • Jumbo-frame • Spans 800 km • Uses CANARIE/ORANs • BCNet in BC • Netera in Alberta AG Retreat, June 9 – 11, 2004

  8. Overview • What is WestGrid? • WestGrid Collaboration and Visualization • Integrating visualization services into AG AG Retreat, June 9 – 11, 2004

  9. Why Collaborationand Visualization (CV)? • The goal of grid computing: accelerate understanding • The human element of grid computing • People are arguably the most important “grid resource” • How do we accelerate understanding? • Understanding through visualization • Understanding through collaboration • The right people, at the right time, with the right information • WestGrid has deployed a CV infrastructure AG Retreat, June 9 – 11, 2004

  10. The WestGrid Collaboration Infrastructure • AccessGrid foundation • AG rooms deployed at each site • AG VenueServer • Functional and Research venues • Bridging for all venues • GridCanada certificates • Wide range of scales and types • Large scale, multi-user rooms • Smart interaction environments • Visualization laboratories • Extended collaboration services • Integrated visualization services • Extended collaboration services AG Retreat, June 9 – 11, 2004

  11. The WestGrid Visualization Infrastructure • Visualization technologies • SGI visualization server • Visualization to the desktop • Access to high end visualization • 20 processors, 8 “pipes” • Centralized management • Hardware, software, expertise • Utilizes core WestGrid network • Visualization displays • Provide access to researchers • Range of displays types • Fully immersive VR rooms • Low cost passive stereo • No glasses auto-stereo • Challenges • How to integrate visualization into our collaboration environments AG Retreat, June 9 – 11, 2004

  12. Visualization Server SFU: Visualization server AG Retreat, June 9 – 11, 2004

  13. Overview • What is WestGrid? • WestGrid Collaboration and Visualization • Integrating visualization services into AG AG Retreat, June 9 – 11, 2004

  14. Quality of Experience in Advanced Collaboration Environments • What is QoE? • Measure of human experience, not technology • User satisfaction requires a good experience • How do we deliver? • Task: What is the user trying to do? • Need: What do they need to accomplish the task? • Services: What services meet the needs? • Technologies: What technologies can provide services? • Collaboration with the NRC • http://www.andrewpatrick.ca/cv/WACE-2003-Corrie-et-al.pdf AG Retreat, June 9 – 11, 2004

  15. Quality of Experienceand AccessGrid • Identifying tasks and needs • What is the user trying to accomplish? • E.g. Collaborative visualization of molecular data set • Create/reserve a venue for the specific task • What are the requirements/needs • Audio, video, shared molecular visualization • Deploying services and technologies • Creating and configuring services • Populate venue with appropriate services/applications • Rat, vic, RasMol • Configure services/applications in the venue for task at hand • Deploying services on technologies • Services are automatically deployed when venue entered • Configured as required for the task AG Retreat, June 9 – 11, 2004

  16. The QoE AG process Task and need identification QoE Web Portal Venue configuration: service specification and service settings Venue Server Venue join Venue Client Venue Client Venue Client Service instantiation Services Services Services AG Retreat, June 9 – 11, 2004

  17. Where are we at? • Populating and configuring venues • Task based web portal • Identifies service requirements • Exploring how to populate a venue • Add apps/services to a venue • Add app/service config to a venue • Add data to a venue • Need to add visualizationfeatures to the portal AG Retreat, June 9 – 11, 2004

  18. Where are we at? • Visualization services are available • Shared RasMol (Argonne) • Shared ImmersaView (EVL) • Shared VizServer (WestGrid) • Alpha version complete • Beta to be publicly available soon • Issues • Requires separate authentication • Application start up • Data in the venue (Grid URL) AG Retreat, June 9 – 11, 2004

  19. What do we need? • Node Services vs Shared Apps • Node services • Node, not machine based • Use a StreamDescription for configuration • Can this be used to control the stream (extensible)? • Node controlled, not venue controlled • Need a way to configure services from venue • Shared Apps • Venue controlled • Can add features based on purpose, not based on node • Venue, not node based • Can’t start up shared apps on other machines in a node AG Retreat, June 9 – 11, 2004

  20. What do we need? • Documentation • “The documentation is thin…” • Ivan Judson, Scheduling and AG, AG Retreat 2004 • Current process • Read high level documentation (not clear if it is up to date) • Read code (example Shared Apps, Node Services) • Modify code • Difficult to determine what is possible • How can we populate venues? • What mechanisms are there for storing data in a venue? • What mechanisms are there for communicating info? • Venue data store, shared app data store, event mechanism, stream description AG Retreat, June 9 – 11, 2004

  21. Questions? AG Retreat, June 9 – 11, 2004
