Currently Grid application developers often configure available application components into a workflow of tasks that they can submit for executing on the Grid. We have developed the Abstract Grid Workflow Language (AGWL) for describing Grid workflow applications at a high level of abstraction.

AGWL has been designed such that the user can concentrate on specifying scientific applications without dealing with either the complexity of the Grid or any specific implementation technology such as Web/Grid services, software components or Java classes. AGWL is an XML-based language which allows a programmer to define a graph of activities that refer to computational tasks or user interactions. Activities are connected by control and data flow links. A rich set of constructs is provided to simplify the specification of Grid workflow applications (see below). Moreover, AGWL supports a generic high level access mechanism to data repositories.

  • Basic Control Flow Construct
    • Sequential constructs:
    • Conditional constructs:
    • Loop construct:
    • Directed Acyclic Graph construct:
  • Advanced Control Flow Construct
    • Parallel section constructs:
    • Parallel loop constructs:
  • Basic Data Flow Construct
    • Link activities' outputs to activities' inputs
  • Advanced Data Flow Construct
    • Access abstract data repositories (e.g. file systems, databases, etc.)

AGWL is the main interface to the ASKALON Grid application development environment and has been applied to numerous real world applications, such as WIEN 2k and Invmod/Wasim.

Askalon pictureAskalon works with the following file extensions:

Note: You can click on any file extension link from the list below, to view its detailed information. The list of extensions used or otherwise associated with the application may not be complete, because many common file extensions on our website, such as jpg (pictures) or txt (text files), can be opened by a large number of applications, or are too general file format. However most, if not all directly associated file extensions should be listed with its appropriate program. Although its likely, that some file extensions may be missing from the list of associated file extensions with the application, yet they can be opened, be part of, or otherwise be associated with the program.
