A Graphical Modeling Environment for the Generation of Workflows for the Globus Toolkit
Francisco Hernández, Purushotham Bangalore, Jeff Gray, Kevin D. Reilly · Kluwer Academic Publishers eBooks · 2005
Grid computing aims at managing resources in a heterogeneous distributed environment. The Globus Toolkit provides a set of components that can be used to build Grid-enabled applications. Presently, applications are typically hand-crafted either by using a set of command line interfaces, or by using a set of Java packages provided by the Java CoG Kit. The purpose of this work is to introduce a high-level layer that abstracts and simplifies the development of applications within the Globus Toolkit context by creating graphical workflows of applications using domain-specific modeling techniques.The expected impact of this effort is a reduction of the development time involved in generating applications for the Globus Toolkit. An additional advantage is to provide a high level view for the construction of Grid applications using the Globus Toolkit that avoids some of the intricacies documented for other approaches. Furthermore, the concepts introduced in this chapter can be employed not only in the context of the Globus Toolkit but with other component frameworks.
