3. GridLab WP12 (MOBILE) 5th GridLab review 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

4. GridLab WP12 (MOBILE) 5th GridLab review 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

5. GridLab WP12 (MOBILE) 5th GridLab review 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

6. GridLab WP12 (MOBILE) 5th GridLab review 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

7. GridLab WP12 (MOBILE) 5th GridLab review 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
