1 Workflow Enactment Engine This is an engine proposed and developed by the University of Melbourne, Australia. It is provided as an execution environment for [xWFL] workflow language . The main characteristics: - utilizes resource discovery using Globus MDS and so-called Grid Market Directory - it applies a workflow language translation just before the scheduling phase (the workflow document is being transformed to a set of ~~tasks~~, ~~dependencies~~...) - it uses a ~~tuple-space~~ concept during workflow enactment as a mean to handle and respond for execution events - it employs ~~just-in-time~~ scheduling strategy {table} Language | Formalism | Flow element | Single-task executor [xWFL] | DAGs | Executable or WS operation | Internal dispatcher entity {table} 1 Resources - {link:J.Yu, R.Buyya\: ~~A Novel Architecture for Realizing Grid Workflow using Tuple Spaces~~|http://www.buyya.com/papers/workflow-grid2004.pdf} 2005-02-09 10:21:51.15 2005-02-09 10:21:51.15
