Open Gateway Computing Environments (OGCE)

The Open Gateway Computing Environments (OGCE) project develops, packages, and integrates software to be used to develop science gateways, which are browser and desktop interfaces to the distributed scientific computing infrastructure such as the NSF XSEDE program. The OGCE is funded by the National Science Foundation’s Software Development for Cyberinfrastructure (SDCI) program. OGCE software includes tools for developing collaborative Web environments based on the Open Social standard; for wrapping science application codes on Grids and Computing Clouds as secure, network accessible services; and supporting complex executions, such as scientific workflows, that require multiple scientific applications to be coordinated.

OGCE component tools include the following:

• OGCE Gadget container, a Google tool for integrating user interface components
• XRegistry, a registry service for storing information about other online services and workflows
• XBaya , a workflow composer and enactment engine
• GFAC, a factory service that can be used to wrap command-line-driven science
applications and make them into robust, network-accessible services
• OGCE Messaging Service supports events and notifications across multiple cooperating services
