The Open Gateway Computing Environments

The OGCE develops, packages and releases software downloads for building Science Gateways, Grid Portals, and related tools for Web access to Grid and Cloud computing resources. Our component projects are described below. Click the link in the Component column of the table below to get download links and build instructions.

OGCE Joins Apache: The OGCE portal and workflow components now are part of two Apache Software Foundation Incubator projects. Apache Rave is the next generation of the OGCE Gadget Container, and Apache Airavata is the successor to the OGCE Workflow Suite. We are transitioning our source code to Apache's SVN.

What Does It Do?

OGCE develops and packages downloadable software for building science gateways. We have several screen capture videos that illustrate how to install and use the software.

Downloadable Components

The following downloadable components are provided while we transition to Apache Airavata and Apache Rave. For the latest source code, please see these project pages.

Click the link in the left-most column for download instructions. Or just go here.

Getting Code

Click the link in the above table for download instructions. We try to keep installation procedures as simple as possible, so the typical process for each component is

  • Get the code. You can either download a tar file or use SVN's checkout command. We support anonymous checkouts and open code browsing through SourceForge. Releases include supporting
  • Unpack it. Use tar to unpack.
  • Edit your properties. Local properties, such as your server's IP address, are defined in the project's top level pom.xml file. Open and edit.
  • Run the command "mvn clean install." We use Apache Maven to manage the build process for all components. Components can be built with the command mvn clean install.
  • Start the web server. The Maven build process will deploy code into a provided Tomcat server. Start the server in the usual way, or use our provided startup-tomcat.sh scripts.

Component projects (portal, server, gadget container, etc) are developed as collections of modules. You can recompile and deploy individual modules using mvn clean install -f path/to/module/pom.xml.

Key to Release Status

  • Stable Releases are provided as TAR downloads. These are stable and will not have major changes to the core, although additional add-on features will be released. These have been integrated into the NMI nightly build test bed. Tagged SVN releases are also available.
  • Development Releases are actively developed and will undergo changes to the core and add-ons. Stable, functioning releases that will correctly build are tagged and accessible via SVN checkouts.
  • Development Previews are actively developed and may undergo dramatic changes. Demonstration releases that will correctly build are tagged and accessible via SVN checkouts. These are "use at your own risk" and may change dramatically.

We encourage collaborations and contributions in developing software, so if you want to help improve codes, particularly development releases and previews, please contact us.
