Support for cooperative experiments in VL-e: from scientific workflows to

knowledge sharing

Objectives …

The demonstration will show the last results in developing

workflow for Grid based systems

and

the integration of tools developed in various Subprograms in VL-e.

The Application Workflow …

Developed in the context of the Ridge-O-grammer use case

Human transcriptome map

Temperature in Amsterdam

DNA curvature of the Escherichia coli chromosome

The Workflow Management System …

• WSRF compliant workflow engine

• Workflow monitoring • Drag-and-drop composition• Hierarchical workflow

creation & execution• User in the loop

• Data streaming • Detach/re-attach capability

Composition panel

Monitoring console

Property panel

WorkflowComponents palette

• Implemented as GT4 based/WSRF service

• Uses GT4 standard delegation service for security

• Uses GSI enabled, private VNC for Graphical modules

• Provides notifications for monitoring the execution

• monitoring of the workflow components:

• Std Out, • Std Err, • Status.
