Triana

• Workflow is represented in XML WSFL-like format
• Nice Java GUI and simple to use execution runtime with master/worker
• Triana Grid Application Toolkit (TGAT) goals: Execution model to include heterogeneous modules executing on remote machines in different languages with automatic compilation? Integrate or extend an existing wrapper generator (such as SWIG, JCI or the XML based wrapper developed at the Dept. Computer Science, Cardiff) to interface with native codes?
• Plans to develop metadata associated with main data flows e.g. history of processing, duration and cost of execution. Standardize metadata into a common XML format and interface to databases of data, programs, and scripts that use metadata
• Uses JXTA via a high-level application API called JXTAServe to be extended to support GAT Grid Services API

Triana code is now released as open source and downloadable code.

However no software available from GAT page (prototype described in PDF)? The best information found about project status is http://trianacode.org/triana/about/index.html (...) Triana is one of two test bed applications for GridLab, a large EU funded project. The aim of GridLab is to develop a simple and robust grid application toolkit (GAT) enabling applications to exploit the power of the GRID. Triana is ready to use GridLab GAT when it becomes available. (...)
