Key Components Introduce along with GME etc Modification GUI Creation of Service Archives Repository Service Container Service Index Service Dynamic Deployment

Implementation Details Implemented as an extension to Introduce tool

from OSU Used JSDL Application_Type to describe the

executable Integrated with GME for management of Input and

Output types Creates a standard operation and writes code to

invoke the executable Creates a command-line client

What Works … We finished a alpha version of the

introduce plug-in Can wrap simple executables as Grid

services Fork Execution works GRAM Integration We have some ideas on how to do Security Still trying to get our heads around generic

Input and Output mapping

Presentations and Outreach Teragrid 2007 Presentation at OGF21 ICR Working Group meeting for caBIG Analytical Services Best Practices Telecon Dev.globus.org incubator

Future Work Wrap more Real Applications as Services Investigate how to map input to the application and

output from the application into well-defined schema elements

Investigate Dynamic deployment of Application service Archives into a stand-alone GT container and test if the new capabilities are discovered using registry

Investigate how Environment required for the execution of an application is met. Look into SoftEnv extensions on RSL.

Investigate and implement Virtual Machine based Provisioning solutions
