<ul><li><p>Open Grid Computing Environmentswww.collab-ogce.orgMarlon Pierce (IU)&amp;Gopi Kandaswamy (RENCI)</p></li><li><p>OGCE SoftwareA bundled set of JSR 168 compatible portlets and services for building Grid portals (Science Gateways).Build with GridSphere.Can will work with uPortal.Sakai has new JSR 168 ContainerOthers possiblePorltets includeGT2 and GT4 GRAM Job submissionGridFTP file transferGPIR clients (can work with Teragrid, for example)PURSe grid registration system.CondorMyProxy credential managementMiscellaneous (Iframes)</p></li><li><p>Supporting Grid Portlet DevelopmentPortlets are built using the Java COG 4s abstraction layer (developed as part of the project).Hides the difference between Globus versionsWe have developed a set of JSF Tag Libraries to simplify Grid portlet development.http://fuji.ucs.indiana.edu/svn/repos/GridTags/trunk/GridTagsBeansWe support JSR 168 Velocity for historical interest.</p></li><li><p>Some OGCE Portal CollaborationsRENCI TeraGrid BioPortalLEAD PortalTeraGrid User PortalTeraGrid Visualization PortalCIMA Crystallography PortalVLAB Portal ProjectNumerous other projects that come and go:PittGrid Portal, UNC-Charlotte Visualization Portal, DES and LSST Astronomy Portals, IU System Portals</p></li><li><p>Future Directions (1/3)General Trend: we want to align with TeraGrid Science Gateways efforts.User logging and reporting Par of TG User Portal nowGenerate reports such as Top 10 users of the portal, Most frequently used applications and the average response times of eachApplications used by individual users. Auditing and accounting Modified GRAM client and server running on TGProvide the user with a list of submitted workflows and jobs along with allocation used totals per workflow and job. Associated portletsEnhanced GPIR capabilities (including MDS data)Predictor portlets (with NWS) (see TG User Portal)</p></li><li><p>Future Directions (2/3)Better support for computational experiments.Generic Service Toolkit (Gopi will describe).Other tools (adapted from the LEAD project)Experimental builder portletsMetadata management services for tracking and storing all aspects of a workflow. </p></li><li><p>Future Directions (3/3)We need better packaging.Currently use Maven 1 with some strategic Ant and shell scripts.Some improvements:More customizable: just download and build what you wantEnsuring all dependencies are metSmaller download footprintMaven 2 can do some of these things but it has reliability issuesYou have to download dozens and dozens of jar files to build your initial repository.Typically doesnt work 100% the first time.</p></li><li><p>Future Directions (4/3)We need to consider Web 2.0 approaches for Science Gateways.See general material from Mondays workshop.http://www.semanticgrid.org/OGF/ogf19/.These are in general compatible with SOA (assuming build your services correctly).But the implication on portals/gateways should be dramatic.We have to decide how much we can shoe-horn into the JSR 168/286 specs.</p></li></ul>
