11. National Alliance for Medical Image Computing http://na-mic.org March 2007 Large scale experiment control Scenario #1 –Use Slicer3 interactively to select parameters –Run across N datasets Scenario #2 –Use Slicer3 interactively to select some parameters –Design of experiments across remaining parameters Assumptions –Single computer, cluster, grid –No direct access to compute nodes –Staged data –Staged programs –Experiment scheduling –Job submission –Experiment control –Job execution robustness –Platform Options Loopy launcher BatchMake Grid tools

12. National Alliance for Medical Image Computing http://na-mic.org Current Slicer3 activities Performance –Resampling, observer madness, intervention Visualization breadth –Cine, lightbox, tensors, plots, CSV, tables Interaction breadth –Tracked cursors, editors, measurements, WWidgets, SWidgets Execution model breadth –Scenes, transforms, coordinate frames, CSV, MRMLImageIO, … MRML breadth –Model hierarchies, grouping, CSV, tables Modules –IGT

13. National Alliance for Medical Image Computing http://na-mic.org Three integration strategies Base Slicer3 modules (interactive modules) –Tight integration with GUI and Visualization subsystems –Need MRML Node, Logic class, GUI class Command line modules (execution model modules) –XML descriptions of executable and shared library modules Wizard based modules –Sophisticated wizard to guide user to setting parameters –Need many MRML, Logic, and GUI classes –EM Segmenter
