Introduce Overview

• A framework which enables fast and easy creation
  of Globus based grid services
• Provide easy to use graphical service authoring
  tool.
• Hide all grid-ness from the developer
• Utilize best practice layered grid service
  architecture
• Integration with other core grid services and
  architecture components
• GAARDS Security Infrastructure (Dorian,
  GridGrouper, CSM)
• Globus Index Service
• Global Model Exchange (GME)
• Cancer Data Standards Repository
• Extension Framework for integrating with other
  architecture components

Inside the Introduce created service

• Services have many moving and configurable parts
  which support features such as
• Advertisement
• Discovery
• Invocation
• Security (Authentication/Authorization)
• Stateful Resources
• The Introduce Toolkit can keep all these features
  in sync as the developer creates and modifies the
  grid service

Creating the Gateway Service

• Manually stage the binary (jar file) on TeraGrid
• Takes in .ser files as input
• Produces results also in a .ser file
• Used the gRAVI plugin for Introduce to create the
  gateway service
• http//www-unix.mcs.anl.gov/neillm/ravi/
• Gateway gridFTPs input data and parameters from
  geWorkbench to TeraGrid
• geWorkbench passes input to the gateway in
  geWorkbenchs native format (caDSR compliant)
• Gateway serializes the input before gridFTPing to
  TeraGrid
• Gateway invokes the staged binary
• Gateway gridFTPs results back to geWorkbench
• Gateway deserializes the result file
• Gateway returns results to geWorkbench in its
  native format
• Gateway service is a secured caGrid service which
  in turn invokes TeraGrid with a caBIG community
  account
