Workflow in Grid Systems
Geoffrey Fox, Dennis B. Gannon · 2004
Abstract—This paper provides an overview of the Concurrency&Computation: Practice&Experience special issue on workflow in Grid systems. It is based on discussions at the Global Grid Forum GGF10 Workflow workshop in Berlin, March 2004 and subsequent analysis of the final papers. We describe the background from both a Grid and Global Grid Forum perspective and the distinctive features of the application requirements. We categorize different types of workflow emphasizing the important input from the distributed computing community. We discuss separately both the different workflow systems (often called (run-time) enginres) and the expression languages like BPEL. We highlight some important outstanding research issues in the conclusion.
