Much of the work that CDIGS does is organized around specific Globus technology areas (e.g., execution management, data, information services).  Those activities are described in the [CDIGS Technology Roadmap].

Some issues (especially those that CDIGS addresses) are cross-cutting, meaning that they require coordinated effort across technology areas. For these issues, the CDIGS team forms a ''tiger team''.  The tiger team is given a specific charge (a problem to solve, a recommendation to generate) and a short time in which to do it. Members are drawn from the Globus areas that are likely to be involved in the solution, but we specifically invite members of the Globus community to participate directly by joining the team. In some cases recommendations from the Tiger Team are presented to the community for further recommendation and discussion.

MDS Re-examination Tiger Team - Completed

MDS provides components for monitoring and discovery of grid resources. While we have made steady incremental improvements to MDS over the last several years, we have not stepped back and reviewed the overall architecture and design in light of ever-changing user requirements and environments. The MDS Tiger Team will serve to fulfill this purpose.

GRAM/RFT/Core Reliability Tiger Team - Completed

The GRAM-RFT-Core Reliability Tiger Team convened on October 3, 2007 and finished in April 2008. It was charged with improving the reliability of the deployed Globus toolkit, with an emphasis on GRAM4 (Web services-GRAM). The tiger team kickoff  led to several performance characterizations, and the completion of a variety of tasks. Additionally, while this team was underway, a significant amount of effort from all the members of this team as well as the Globus team in general (as part of the TeraGrid Gateway-Debug effort) were devoted to helping the LEAD team meet their Spring Weather Challenge. Nearly all the improvements conceived & developed during the Tiger team were put into practice on TG to help LEAD. As a result of this effort, both the performance and the reliability of GRAM was significantly increased especially on LEAD runs.  GRAM performance improved (in general) by a factor of 3, and workflow reliability was significantly improved due to improvements in GRAM, RFT, Java WS CORE, and GridFTP. See the TG performance paper "Engaging with the LEAD Science Gateway Project: Lessons Learned in Successfully Deploying Complex System Solutions on TeraGrid"

Service Oriented Science Requirements Tiger Team - Completed

The Service Oriented Science Requirements Tiger Team convened on October 29, 2007 and completed most of the stated objectives by Feb. Specific user communities suitable for the proposed service-oriented science technologies were identified and contacted; and a draft document of user requirements was completed. In Feb '08, work on this project transitioned from CDIGS to the CEDPS program.

WS Core Specification Resync - Completed

The WS Core Specification Upgrade Tiger Team WS Core Specification Upgrade Tiger Team convened from March 1 to March 27, 2007 and was charged with providing a recommendation to the Globus community on whether to upgrade Core to the latest WS-RF,WS-N,WS-A specifications.  Its significant  results were that a report and recommendation to upgrade were made. The community was then presented with this analysis, provided additional input and agreed that the upgrade was needed. See Core Upgrade Recommendation Results.
