1 Simple Conceptual Unified Flow Language Is used in the [myGrid] project. It defines a high-level workflow description language that allows the user to map a conceptual task to a single entity with a minimal amount of implementation specific information (the translation to lower-level entities is done by the underlying system called the [IT Innovation Enactment Engine]). Three main entities are defined: processors, data-links and coordinations. Unfortunately it is not possible to specify user-defined constraints neither to processors nor to data-links. There is a basic exception handling mechnism included. It supports retry of invocation with configurable timeout and number of retries, and user-defined alternatives for processors failing constantly. 1.1 Related - [Taverna] - [myGrid] - [XScufl] 2005-07-01 12:34:10.036 2004-09-08 15:18:34.148
