Description

Complete scientific analyses are complex, usually involving multiple stages and multiple applications. As users gain more experience with the grid infrastructure, they look for tools to manage complete analysis workflows. These tools handle the bookkeeping, job execution, and data management, allowing the researcher to concentrate on the science rather than tedious grid details.

Participants in this session will hear presentations that provide a good overview of the available workflow managers and how they can be (easily) used to access resources on the EGEE production grid infrastructure. Each workflow manager is usually optimized for particular use cases and has it's own strengths and weaknesses. Recent work on making workflow managers interoperable may allow users to mix and match them on sub-workflows to optimize a complete analysis.

The agenda provides plenty of time for questions and discussions. Participants should be prepared to share their own experiences with workflow managers and their needs regarding improvements.

  1. 153. Enabling the execution of various workflows (Kepler, Taverna, Triana, P-GRADE) on EGEE
    Mr Tamas Kukla (Univ. of Westminster)

    End-user environments and portal technologies
    Oral
    Different communities use different workflow (WF) systems and when they start to use EGEE they would like to run their WFs on EGEE sites. So far this required the porting of the various WF systems to EGEE. With the P-GRADE GEMLCA portal this activity can be reduced to the registration of the required WF engine in the GEMLCA repository. Then users of the WF system can run their WFs via the...

  2. 116. Workflow management tool for Earth science applications
    Viet Tran (Institute of Informatics, Slovakia)
    02/03/2009, 17:50
    Grid Services exploiting and extending gLite middleware
    Oral
    In this paper, we present workflow management tool for Earth science applications in EGEE. The workflow management tool was originally developed within K-wf Grid project for GT4 middleware and has many advanced features like semi-automatic workflow composition, user-friendly GUI for managing workflows, knowledge management. In EGEE, we are porting the workflow management tool to gLite...

  3. 163. SchedScripter: Workflows for Grid-based Human Resources Scheduling Applications
    Mr George Goulas (University of Patras, Electrical & Computer Engineering Department)
    02/03/2009, 18:10
    Experiences from application porting and deployment
    Oral
    SchedScripter is a web services based, BPEL workflow framework for distributed scheduling applications over a Grid environment. It provides abstract constructs and communication patterns for the distributed scheduling application components. In this contribution, we discuss our experiences from the adaptation of an examination timetabling problem as a grid based application SchedScripter. The...

  4. 107. An Interoperable Grid Workflow Management System
    Dr Maria Mirto (SPACI Consortium & University of Salento Lecce)
    02/03/2009, 18:30
    Scientific results obtained using grid technology
    Oral
    A large-scale simulation experiment in e-Science can be modeled by using a workflow. A Workflow Management System (WFMS), developed at University of Salento in Lecce, initially implemented as a client-server system in the 2004, has been recently re-enginered for scheduling and monitoring the jobs in a heterogeneous Computational Grid based on the gLite, Unicore and Globus middleware....
