A Pattern-based Software Engineering Tool for Grid Environments
May 2005
A pattern-based software engineering tool for constructing workflow
based applications is described. The tool provides a novel way of
composing applications executing over Grid resources. The tool
provides a structured design approach, centered on the manipulation of
patterns through pre-defined pattern operators. Patterns and operators
are divided into two categories: structural and behavioural.
Structural operators act upon structural patterns to build reusable
architectures. Behavioural patterns define the data and control flow
dependencies between components in the architecture. Components within
a pattern are subsequently instantiated with particular executables,
and behavioural operators allow subsequent execution control and
reconfiguration of the application.
