  1. WP12: Access for mobile users What's new in mobile user support Piotr Grabowski, Bartek Lewandowski www.gridlab.org/mobile Poznan Supercomputing and Networking Center 5th GridLab Review,8 April 2005, Amsterdam

  2. Overview • Mobiles architecture • Mobiles features • Use cases, scenarios • Current status, list of deployments • What’s new in WP12 • Deliverables • Future research and deployments • Integration with GridLab WPs • Summary 5th GridLab review

  3. Mobiles architecture • GridLab Mobile Client (GMC) • J2ME/CLDC/MIDP 1.0 midlet – variety of devices available (Mobile phones, Personal Digital Assistants (PDAs), Notebooks) • Internal repository for storing data, used later in off-line state and preparing data, to be sent in on-line state • Gateway • Mobile Command Center (MCC) acts as a gateway between mobile client and Grid services • Developed in Java as a GridSphere portlet with separate „mobile” context. • „Pluggable” – open for new grid services • Automatically grabs the device profile (device class, screen size, color depth, etc) • Services (GSI-enabled Webservices) • MessageBox, Visualization Service for Mobiles, GRMS 5th GridLab review

  4. Mobiles features • Main features: • GRMS v 1.9.6 Job submission and management • User notifications as Email and SMS • Storing notification messages in Message Box for further retrieval • Browsing Message Box for messages • Visualization Service for Mobiles usage to show device capability-dependent images to the user • Gateway management via portlet interface • Off-line work possibility for GridLab Mobile Client • No-typing interface of GridLab Mobile Client • Wide range of supported devices 5th GridLab review

  5. Use-case 1: Notification scenario • The user is notified about important events occurring in the Grid (like jobs status changes, application output availability) • Mobile grid services • Notifications • httpg://rage1.man.poznan.pl:8449/axis/services/Notifications • Message Box • Running on httpg://rage1.man.poznan.pl:8445/axis/services/MessageBox 5th GridLab review

  6. Use-case 2: Mobile visualizations scenario • The user check the application output in form of visualization prepared exactly according to the User’s device capabilities • Visualization Service for Mobiles • J2ME midlet interacts via Mobile Command Center with Visualization Service for Mobiles (developed by WP8) • Background • Mobile client constraints • Mobile user expectations concerning extra-visualization features • Viz service downscales the visualizations into „mobile” format • on the basis of dynamic mobile profile: screen size, color depth • 2 different modes • Display downscaled images, cropping/zooming images • Image sequences 5th GridLab review

  7. Use-case 3: Job steering scenario • „Collaborative scenario” – the user can steer the application (even not being an owner) from mobile device. • Get jobs list/migrate/resume/suspend/cancel/edit/info/history • Submit new job on the basis of edited/modified description of already finished jobs • Register for user notifications related to the running job • Get project list and job list related to project • Register for project notifications related to the running job 5th GridLab review

  8. Current status • Mobile client • J2ME midlet is running on mobile phones, PDAs and PC laptops • OTA repository on http://rage1.man.poznan.pl:8086/mbox • Gateway • Mobile Command Center acts as a gateway between mobile client and Grid services • Running as GridSphere portlet on http://rage1.man.poznan.pl:8089/gridsphere/gridsphere • Services • Message Box, Notifications, VSfM, GRMS 5th GridLab review

  12. Deployments list • Testbed deployments • MessageBox GridService httpg://rage1.man.poznan.pl:8445/axis/services/MessageBox • Notification GridService httpg://rage1.man.poznan.pl:8449/axis/services/Notifications • Mobile Command Center in GridSphere http://rage1.man.poznan.pl:8089/gridsphere/gridsphere • GridLab Mobile Client http://rage1.man.poznan.pl:8086/mbox • Research deployment • Poznań University of Technology, MobileGrid project: MessageBox GridService, MCC with GMC deployed 5th GridLab review

  13. What’s new in WP12 (since previous review) • Mobile client • Jobs steering features • „Collaboration scenario” ready • Off-line work possible • Gateway • MCC management via Portal • Notification • Compliance with latest GRMS notification schema • Message Box • Small changes for external users • Jobs steering • Get jobs list/resume/suspend/cancel/edit/info/history of users group jobs • Submitting new job on the basis of edited/modified description of already finished jobs • Registering for project and user notifications related to the running jobs • Overall • Last deliverable and User & Admin guides to provided software 5th GridLab review

  14. Deliverables, guides, manuals • Deliverables • D12.1 „Mobile-enabled information exchange” (GridLab Mobile Client, servlet gateway and simple services (Message Box) • D12.2 „Mobile-enabled grid middleware and/or grid gateways”(Message Box Webservice, Notification WebService, Mobile Command Center gateway ) • D12.3 „Small-bandwidth optimized adaptive grid services”(MCC gateway, GMC,Visualization Service for Mobiles-WP8) • D12.4 „Minimal Grid Interface (MGI)” (MCC gateway, GMC) • D12.5 „Offline-Connectors, synchronization tools” (MCC gateway, GMC) • All deliverables available at: http://www.gridlab.org/Project/Documents.html 5th GridLab review

  15. User & Admin guides • GMC user guide • Features installation and usage guides • http://gridlab.org/Resources/Deliverables/D12.5.userguide.pdf • Mobile services admin guide • Features installation and administration guides of all mobile services • http://gridlab.org/Resources/Deliverables/D12.5.adminguide.pdf 5th GridLab review

  16. Future research and deployments • Telemedicine (mHealth) • InteliGrid • MIDP 3.0 migration 5th GridLab review

  17. Integration with GridLab WPs • WP4 (portal) • MCC as the GridSphere portlet • WP6 (security) • GAS (authorization) • WP8 (data&vis) • Storage Box (metadata for Message Box) • Visualization Server for Mobiles • WP9 (GRMS) • Notification service for GRMS • GRMS features from mobile client • WP10 (iGrid) • Registering services: notification, message box • Discovering other services • WP11 (monitoring) • Logging service 5th GridLab review

  18. Summary • Mobile services and clients are ready to use in various scenarios and use cases giving access to the grid for mobile users • Documentation (User & Admin guides) and all deliverables delivered • Mobile users support WP – contacts: www.gridlab.org/mobile mobile@gridlab.org • Thank you! 5th GridLab review
