Towards an end-user programming environment for the grid

Abstract

For end users, building applications with current Grid programming paradigms still remains a difficult and time-consuming task by dealing with excessive low-level details of provided APIs. We present a high-level application description language called Grid Service Markup Language (GSML) and its supporting development environment, to facilitate end-user programming in an approach that applications could be visually composed by well-defined software components in an event-driven fashion. Core constructs of GSML language, Pipe, Event, Target, and EventSet, are developed to address the complexity of dynamic interaction behaviors of grid applications. By raising the level of abstraction as well as simplifying the programming model, GSML allows end users to build grid applications easily with improved productivity. © Springer-Verlag Berlin Heidelberg 2005.
