Putting It All Together
Software Strategy
• Focus on gadget container and tools for running science applications on grids and clouds.
• Provide a tool set that can be used in whole or in part.– If you just want GFac, then you can use it without
buying an entire framework.
• Outsource security, information services, data and metadata, etc to other providers.– MyProxy, TG IIS, Globus, Condor, XMC Cat, iRods, etc.
More Information• This is downloadable, packaged software.
– Apache Maven build system provides everything you need to to build the gadget container, gadgets, workflow composer, and backing services.
– Get code by anonymous SVN checkout.• Email: [email protected],

Demos Next
The OGCE Application Registry gadget allows users to interactively register hosts and applications that are
dynamically wrapped as Web services.
The OGCE Gadget Container allows you to build portals out of public and private Google Open Social gadgets. Supports HTTPS.
Downloadable, packaged software.
The OGCE Experiment Builder gadget allows users to create projects and experiments out of previously
composed workflows.
The XBaya workflow composer allows you to build scientific workflows from services running across the TeraGrid. This is part of our workflow suite.
OGCE Tools for Science Workflows
What Is a Science Gateway?• Web and desktop user interfaces and user-centric Web
services for accessing Grid and Cloud resources.– Clusters, supercomputers, mass storage– Applications, databases– Workflows
• Example Science Gateways from the NSF TeraGrid– GridChem: computational chemistry– UltraScan: biophysics computational analysis – LEAD: Atmospheric science– BioDrugScreen: drug docking, scoring, and discovery.
• Many others: see https://www.teragrid.org/web/science-gateways/gateway_list
• This demo is about software that powers gateways.
