Redesigning the SEGL problem solving environment: A case study of using mediator components

Abstract

The Science Experimental Grid Laboratory (SEGL) problem solving environment allows users to describe and execute complex parameter study workflows in Grid environments. Its current implementation provides much high-level functionality for executing complex parameter-study workflows. Alternatively, using a toolkit of mediator components that integrate system-component capabilities into application code would allow to build a system like SEGL from existing, more generally applicable components, simplifying its implementation and maintenance. In this paper, we present the given design of the SEGL PSE, analyze the provided functionality, and identify a set of mediator components that can generalize the functionality required by this challenging application category. © 2007 Springer Science+Business Media, LLC.
