4. LRMN Sorina POP, Tristan GLATARD CIRA, 2 juin 2009 4/10 Grid environment for medical imaging Reliable and responsive grid execution Successful execution of one application on a grid node Distant grid node environment and application customization Application parallelization MPI (Message Passing Interface) -> Simri Split the simulation into independent jobs (Monte Carlo) -> Gate Execution framework: advanced tools for Job submission, monitoring and retrieval Integration into service platforms High level interface

5. LRMN Sorina POP, Tristan GLATARD CIRA, 2 juin 2009 5/10 Reliable and responsive grid execution DIANE Registers/removes agents Schedules tasks on agents Stdout/err transfers EGEE – gLite Schedules agents on grid sites Transfer input/result files to/from worker nodes

6. LRMN Sorina POP, Tristan GLATARD CIRA, 2 juin 2009 6/10 Execution framework Moteur workflow engine Workflow execution Each application is described as a workflow (using Taverna) Job submission, input selection and data piping between jobs Moteur – DIANE interface Provides generic agents Starts DIANE master and submits DIANE agents

7. LRMN Sorina POP, Tristan GLATARD CIRA, 2 juin 2009 7/10 Graphical interface to the grid VBrowser Provides user interface to the grid Browses input/result files Launches Moteur Follows experiment progress (job monitoring) Application: the Gate-Lab GATE-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 Gate-Lab client

8. LRMN Sorina POP, Tristan GLATARD CIRA, 2 juin 2009 8/10 Perspectives (I) VIP – Virtual Imaging Platform Goal Enable heavy simulations: multimodal, dynamic Store and retrieve data (organ models and simulated images) Multi-platform execution Large-scale grids (EGEE, NorduGrid) Local clusters (Creatis, IN2P3) GPU
