A Graphical Frontend to Key Services for Utilization of GridEnvironments: A CharonGUI Use Case

The Charon Extension Layer (CEL) is a unique generic sys tem for computational jobs and applications management within grid environments. It provides a sophisticated command-line interface that encapsulates all operations required to control a computational job lifetime - it allows users to submit their jobs, check jobs’ statuses and get results using only three basic commands. In this paper we present CharonGUI - a graphical user interface built over the original CEL. CharonGUI adopts all advantages of the CEL with their benefits and turns them into a graphical representation. Moreover, CharonGUI simultaneously brings a set of new interesting features that offers additional comfort for the grid end users. CharonGUI is expected to complement the command-line version of CEL allowing users to have both approaches available in parallel.
