  1. Support for cooperative experiments in VL-e: from scientific workflows to knowledge sharing

  2. 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.

  3. The Application Workflow … Human transcriptome map Developed in the context of the Ridge-O-grammer use case DNA curvature of the Escherichia coli chromosome Temperature in Amsterdam

  4. The Workflow Management System … • 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. • WSRF compliant workflow engine • Workflow monitoring • Drag-and-drop composition • Hierarchical workflow creation & execution • User in the loop • Data streaming • Detach/re-attach capability Workflow Components palette Composition panel Monitoring console Property panel

  5. The Workflow Management System SOA extensions • Tools for creating workflow components description • CLAMP: Connecting LAnguage for Modules and Programs • Web Service Harvester • (RPC Style WSDL) • Semantic tools • SAW: Semantic Annotation for Workflow • HAMMER: Hybrid-bAsed Match-Maker for E-Science Resources

  6. The Workflow Management System SOA extensions Type here a valid URI • Tools for creating workflow components description • CLAMP: Connecting LAnguage for Modules and Programs • Web Service Harvester • (RPC Style WSDL) • Semantic tools • SAW: Semantic Annotation for Workflow • HAMMER: Hybrid-bAsed Match-Maker for E-Science Resources

  7. The Workflow Management System SOA extensions • Tools for creating workflow components description • CLAMP: Connecting LAnguage for Modules and Programs • Web Service Harvester • (RPC Style WSDL) • Semantic tools • SAW: Semantic Annotation for Workflow • HAMMER: Hybrid-bAsed Match-Maker for E-Science Resources

  8. WSRF Services - WS-VLAM engine - workflow component repository The Setting of the Demo VLe Studio • WS-VLAM composer • VBrowser • Semantic tools SAW: Semantic Annotation for Workflow CLAMP: Connecting LAnguage for Modules & Programs HAMMER: Hybrid-bAsed MatchMaker for e-Science Resources Matrix-Sara PoC environment SRB pc-vlab19.uva DAS-3 RP environment Computing Nodes • Workflow components • Grid Middleware  GT4

  9. The Scenario of the Demo User start VL-e Studio • Search for services for the workflow • Upload in the workflow composer • Compose the workflow • Search for input data set in the SRB • Set the workflow parameters • Execute the workflow • Monitor the execution Matrix-Sara PoC environment SRB pc-vlab19.uva DAS-3 RP environment
