Grid environment for medical imagingGrid environment for medical imaging

• Reliable and responsive grid execution Successful execution of one application on a grid nodeDistant grid node environment and application customization

• Application parallelization MPI (Message Passing Interface) -> SimriSplit the simulation into independent jobs (Monte Carlo) -> Gate

• Execution framework: advanced tools forJob submission, monitoring and retrievalIntegration into service platforms

• High level interface

Execution frameworkExecution framework

• Moteur workflow engineWorkflow execution

• Each application is described as a workflow (using Taverna)

Job submission, input selection and data piping between jobs

• Moteur – DIANE interfaceProvides generic agents

Starts DIANE master and submits DIANE agents

Graphical interface to the gridGraphical interface to the grid

• VBrowserProvides user interface to the grid

Browses input/result files

Launches Moteur

Follows experiment progress (job monitoring)

• Application: the Gate-LabGATE-Lab client (VBrowser plugin)

• Parses simulation (mac) file, zip inputs• Stores inputs on the grid, submits workflow• Keeps track of simulation history

GATE-Lab server• Launches workflow engine• Starts DIANE pilot-job master• Submits agents when necessary

VBrowser
