Summary


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

GatewayMobile 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

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


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 servicesNotifications

httpg://rage1.man.poznan.pl:8449/axis/services/Notifications

Message BoxRunning on httpg://rage1.man.poznan.pl:8445/axis/services/MessageBox


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 MobilesJ2ME midlet interacts via Mobile Command Center with Visualization Service for Mobiles (developed by WP8)

BackgroundMobile 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 modesDisplay downscaled images,

cropping/zooming images

Image sequences


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
