WFEE

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
