  1. GridSphere Status Update Jason Novotny novotny@aei.mpg.de Lawrence Berkeley National Laboratory Jason Novotny, Michael Russell, Oliver Wehrens The GridSphere Project www.gridsphere.org GridSphere / Portlets 2005

  2. GridSphere Status • Who we are ;-) • What have we done • What are we doing now • Where we are going GridSphere / Portlets 2005

  3. The GridSphere Project • The primary goal of the GridSphere Project is to develop a Grid portal framework that we call GridSphere. • GridSphere is a JSR-168 compliant portlet container that offers a set of core portlets that provide the base functionality we think is required for all Web portals. • GridSphere also provides a framework for developing and packaging portlets as well as additional libraries to make portlet development easier GridSphere / Portlets 2005

  4. The GridSphere Portal • Overall goal to build the best open source standards compliant portal designed to meet the needs of the Grid community • Originally funded by the EU GridLab project spanning 3 years since 2002 • Bringing together best of breed technologies in both web and grid technologies • Building a community of users and developers and continuing to add new exciting scenarios GridSphere / Portlets 2005

  6. GridSphere 2.0 Feature List • Portlet API passed Sun TCK and is 100% JSR 168 compliant • Additional Portlet API implementation nearly fully compatible with IBM's WebSphere 4.2. • Support for the easy development and integration of new portlet applications • Higher-level model for building complex portlets using visual beans and the GridSphere User Interface (UI) tag library. • Flexible XML based portal presentation description can be easily modified to create customized portal layouts. • Built-in support for Role Based Access Control (RBAC) separating users into guests, users, admins and super users. • Sophisticated portlet service model that allows for creation and reusability of new business logic with support for persistence of data

  7. GridSphere 2.0 Feature List ... • Persistence of data provided using Hibernate OQL for database support • Integrated Junit/Cactus unit tests for complete server side testing of portlet services including the generation of test reports. • GridSphere core portlets: • Login, Logout, Locale settings • Profile personalization and Layout customization • Administration portlets for creation of users, groups, portlet management and portal layout customization • Localization support in the Portlet API implementation and portlets support French, English, German, Czech, Polish, Hungarian and Italian. And now Arabic and Chinese • Open-source and 100% free! :-)

  8. GridSphere’s Grid Portlets • The GridSphere portlet container is designed to be web application independent. Indeed, one of the key advantages of the Portlet API is the reuse of web applications. • Thus, the GridSphere portlet container does not contain any support for using Grid technologies. • Instead, GridSphere’s Grid related functionality is contained in a web application we call Grid Portlets. • Grid Portlets, together with the GridSphere portlet container, offers a generic Grid portal and can be used to develop application-specific Grid portal applications.

  9. How it all started…. • Think back to 2002… • Early Grid Portal projects: Grid Portal Development Kit, HotPage, Astrophysics Simulation Collaboratory • GPDK and HotPage received significant attention as early interfaces to the Grid • Introducing Web Portals and portlet concept • Jetspeed 1 early portal demonstrating power and concept of portlets • Commercial application vendors providing in-house portlet-like solutions • No real standards and landscape was quickly evolving…. GridSphere / Portlets 2005

  10. A few key milestones • Spring 2002: Completed design document and analysis of existing portal / grid solutions • August 2002: Wrote the first line of code • December 2002: Functional portal prototype using Portlet API borrowed from WebSphere API • 2003: GridSphere evolves into highly functional portal complete with core set of portlets, sophisticated service model and visual tag library • August 2003: !st Portals & Portlets Workshop UK • January 2004: JSR 168 Portlet API implementation • February 2004: GS appears in IBM developerWorks article • March 2004: GS passes Sun Technology Compatibility Kit • November 2004: OGCE is JSR compliant and can be dropped into GridSphere portal demonstrating true interoperability!

  11. Progression of Code GridSphere / Portlets 2005

  12. Where are we at? • A primary goal has been to engage global community • GGF hosted GridSphere tutorials Oct. 2004 • Upcoming UK workshop March 3/4 • Thousands of downloads all over the world since March 2004 • 80% commercial / 20% academic • Adopt standard / open source engineering practices • Mail lists (over 165 users subscribed) • CVS • Bug tracker bugs.gridsphere.org • GridSphere 2.0.2 in maintenance mode • New features continuing to be added as needs/requests arise GridSphere / Portlets 2005

  13. Download Statistics GridSphere / Portlets 2005

  14. Ongoing Collaborations • Cactus portal at Albert Einstein Institute • Interface to Cactus numerical relativity application / provide physicists with interface for launching jobs & viewing results • Grid Portal at Canadian National Research Council • Provide controlled remote access to NMR spectroscopy instruments • GEON earth sciences portal / CHRONOS portal • Manage/visualize/analyze vast amount of geoscience data and large scale databases • Pgrade portal at SZTAKI Hungary & Univ. Westminster UK • Creation, execution and monitoring of complex workflows • Many, many more… GridSphere / Portlets 2005

  15. Future Looks Bright • GridSphere adopted by countless academic and commercial projects • Seeking collaborations & funding to continue to apply our knowledge in portals and grid technologies • GS supported under D-Grid (German Grid) initiative • GS adopted under HPC Europa project • Continue to focus on standards /emerging technologies • WSRP integration planned for March at UK workshop • JSF already supported (one of the first to do so) • Content management and repository standards JSR 170 / Jakarta Slide • Business Process Management (Grid?) • Focus on sharing solutions • Delivering truly usable end-user environments!
