Objective:

• Enable Slicer3 to execute work in a distributed grid environment
• Enable NA-MIC algorithms to be tested in a distributed grid environment

Progress:

• Installed and updated grid infrastructure components: implemented configuration for Condor/Globus/GSI to allow NA-MIC and external users to access UCSD computational resources.
• Defined Data Execution Model for Slicer3 - The purpose of this is to facilitate a "run-everywhere" philosophy for algorithm writers. If NAMIC adopts a standard for algorithm "self-description" that is followed when command line executables are written, Slicer, the grid, clusters, etc... should be able to use the executables directly in their environment.
• Defined API for the Grid Interface - this API enables the configuration of available cluster resources and allows the running of algorithms on this distributed grid environment
• First implementation of the Grid Wizard (GWiz) is now in testing for a select set of algorithms. A beta release is scheduled for the NAMIC 2007 Summer Programmer's Week. Additionaly, an initial integration with the Slicer3 environment has been accomplished (see image thumbnail)
