Generation N Data Management System 0.7.0

The Generation N Data Management System (GNDMS) is a set of RESTful services and associated tools for distributed grid and cloud data management based on staging and co-scheduling. It’s what you might want to use if you have big chunks of data that need to be copied around between supercomputer centers in an orchestrated, and secure way.

GNDMS abstracts from data sources via a data integration layer and provides logical names, data transfers via GridFTP and HTTP, proper handling of GSI certificate delegation and workspace management.

Besides data management functionality the implementation provides components for remote logging, run-time reconfiguration, persistence, and fail-over.

Since version 0.6.0 GNDMS is no WSRF-based GT4 service anymore. Thus GNDMS can be deployed in any Servlet 2.5 compliant Application Container. However using the CoG Globus bindings, we achieve interoperability with GSI, MyProxy and GridFTP form both Globus Toolkit 4 and the new plain Globus Toolkit 5.

Originally, GNDMS was written and deployed for the data management needs of the Collaborative Climate Community Data and Processing Grid (C3-Grid) and is now being used in the Plasma-Technologie-Grid (PT-Grid) as part of the German D-Grid grid computing initiative. Nevertheless, the implementation is flexible and has been written for reuse by other grid projects with similar data management requirements.

GNDMS was developed at Zuse Institute Berlin (ZIB).
