A scientific workflow system based on GOS

Abstract

With the advent of grid and application technologies, domain scientists are building more and more complex applications on distributed resources. In order to enable scientists to conduct application scenarios conveniently, scientific workflow is emerging as one of the most important and challenging grid application classes. GOS (Grid Operating System) is a novel grid middleware and can provide various scientific applications for scientists. In this paper, a grid-oriented scientific workflow management system is designed and integrated into GOS. Workflow engine uses light-weight threading techniques and event-driven mechanism to instantiate and dispatch jobs. Some important components will be discussed, and the main implements of the system are also introduced. © 2010 Springer-Verlag.
