- 4. OGCE and Gateways We develop and package software for use by TeraGrid Science Gateways and other resources
- 5. BioVLAB use OGCE tools to run on Amazon
- 6. A lot of this comes from active Gateways.
- 7. Information Services (GPIR, QBETS): TeraGrid User Portal
- 9. Resource Discovery Service, File Browser Applet: TGUP, GridChem
- 10. Gadgets, Open Social Containers: SIDGrid, OLSG
- 11. We contribute codes back to these projects. GatewaysOGCESoftware
- 12. Grid Portal SoftwareJava-basedCode managed by Source Forge SVN. Get it by anonymous SVN checkoutDownload the Tar: http://ogce.svn.sourceforge.net/viewvc/ogce/tags/ogce-portal-only-2.5-release.tar.gzOne-line build: mvn clean install.Download has everything you need except Java.
- 13. File browser front end from OGCE portal download
- 14. Workflow: GFAC and XBaya
- 15. LEAD: A Weather Forecasting WorkflowWRF-Static running on TungstenOGCE Workflow Tutorial
- 16. Nightly builds on 14 linux, Mac PPC, and Mac X86
- 18. Some OGCE ServicesInformation Web Services and build framework
- 19. Resource Discovery ServiceExtracted from the TeraGrid User PortalContributed by Rion Dooley, TACCAxis2 Web serviceIntegrates information from INCA, GPIR services.What machines are in my GridWhich ones are actually running?Works with TeraGrid deployed services, but you can use it with your own information service installations.
- 20. Resource Prediction Service (RPS)Predicts an optimal set of resources for running scientific applications
- 21. Predicts a set of resources on which the sum of data transfer time, queue wait time and compute time for the application will be minimum
- 22. Data transfer time: Uses input data size and NWS info
- 23. Queue wait time: Uses QBETS info
- 24. Compute time: Uses application performance info
- 25. Axis2 web service with a MySQL backend
- 26. RPS is a subset of the Fault Tolerance and Recovery service used in LEAD and VGrADSPackaging ServicesEverything builds with one commandmvn clean installWe use Apache Maven 2 for builds.Structured, modular builds and consistent layoutsBuild a single module: mvn clean install –fsomemod/pom.xmlWe include Apache Tomcat in the download, so all you need is Java and MySQL.Suitable also for the NMI build and test system.Want the Javadoc? mvnjavadoc:javadoc
- 27. Upcoming ServicesXMC-CAT metadata cataloging service with JSDL sample implementation.Swarm Web Service for mass job submission and management.http://escience2008.iu.edu/sessions/SWARM.shtmlGPIR Web Service for information on your Grid. This is being repackaged; older packaged version (but same code) is already available.GFAC and XRegistry services Available now using XSUL Web service engine
- 28. OGCE and Web 2.0
- 30. OGCE Strategies for Web 2.0Java COG --> JavaScript COG (Cyberaide)JavaScript can be integrated with many different frameworks: PHP, JSP, JSF, RoR, etcIntegration with JSON-REST style services.Enable mashups, integrate with Jquery, etc.Portlets--> Google and Open Social GadgetsJSR 168 Containers-->Open Social ContainersOrkut, LinkedIn, MySpace, etcApache Shindig, Sakai 3, other open sourceWeb Services --> REST Services
- 31. AuthenticationHow to authenticate through the Cyberaide JavaScript API?// construct an authenticator object for authentication// using myproxy// make sure to use the attributes keys specified here.var auth = org.cyberaide.js.jsAuthenticator(url);auth.setAttribute("host", "myproxy.teragrid.org");auth.setAttribute("port", 7512);auth.setAttribute("user", ’YOURTGUSERNAME');auth.setAttribute("password", ’YOURPASSWORD');// currently only 'myproxy' is supportedauth.setProvider("myproxy");http://cyberaide.org at Rochester Institute of Technology
- 32. Cyberaide JavaScript API SummaryAuthenticationJob and Workflow SubmissionJob MonitoringFile management Listing, upload, download, third party transfer, etc.Graphical components
- 33. Example OGCE Google Gadgets: MOAB dashboard, remote directory browser, and proxy management. Built with GTLAB.
