Teuta: A Tool for UML Based Composition of Scientific Grid Workflows

Overview Workflows are considered to be one of the most relevant programming models for the Grid. In the past many workflow languages have been developed. However, most of them are textual-oriented, are based on a self-defined notation, or lack an adequate tool-support. Therefore, there is a need for streamlining the task of Grid workflow specification. This paper presents the graphical editor Teuta, which the author has tailored for the specification of scientific Grid workflows. Moreover, the author has integrated Teuta with the Askalon Grid Environment (AGE). Teuta serves for AGE as a user interface for workflow composition, submission, controlling and monitoring. In addition, the paper presents the Domain Specific Language (DSL) for Grid workflows that is based on the latest standard of the Unified Modeling Language (UML).
