Aims and scope

In e-Science environments, Scientific Workflow Management Systems (SWMS) hide the integration details at different layers of middleware such as for managing Grid resources, computing tasks, data and information, and automate the management of experiment routines. The workshop focuses on practical aspects of utilising workflow techniques to fill the gap between the e-Science applications on one hand and the middleware (Grid) and the low level infrastructure on the other hand. Recently development in Grid technology have shown a convergence between business workflow standards such as BPEL4WS and scientific workflows and scientific workflow management systems: design, implementation, applications in all fields of computational science, interoperability among workflows and the e-Science infrastructure,

 e.g., knowledge framework, for workflow management. To achieve such a goal, in the context of the Virtual Laboratory for e-Science (VL-e) project concerted research is carried out along the complete e-Science technology chain, ranging from applications to networking, focusing on new methodologies and re-usable components. The mission of the VL-e project is to boost e-Science by creating an e-Science environment and carrying out research on methodologies.

The workshop aims to provide a forum for researchers and developers inside and outside the VL-e communities in the field of workflow and e-Science applications to exchange the latest experience and research ideas on utilising workflow and business workflow standards in addressing challenging requirements in e-Science applications.

 

Program

The workshop invites well known  researchers in the domain of workflow systems from both academia and industry to present the last research outcome in using workflow systems and standards to tackle e-Science issues:

  W21a: (Maurits room ) 11:30 - 13:00

 

          11:30 - 12:00 Ewa Deelman “Meeting the Challenges of Managing Large-Scale Scientific Workflows in Distributed Environments”,

 

Abstract—In this talk we discuss several challenges associated scientific workflow design and management in distributed, heterogeneous environments. Based on our prior work with a number of scientific applications, we describe the workflow lifecycle and examine our experiences and the challenges ahead as they pertain to the user experience, planning the workflow execution and managing the execution itself.

 

           12:00 - 12:30 Bertram LudäscherScientific Workflows: More e-Science Mileage from Cyberinfrastructure

 

Abstract We view scientific workflows as the domain scientist’s way to harness cyberinfrastructure for e-Science. Domain scientists are often interested in “end-to-end” frameworks which include data acquisition, transformation, analysis, visualization, and other steps. While there is no lack of technologies and standards to choose from, a simple, unified framework combining data modeling and processoriented modeling and design of scientific workflows has yet to emerge. Towards this end, we introduce a number of concepts such as models of computation and provenance, actor-oriented modeling, adapters, hybrid types, and higher-order components, and then outline a particular composition of some of these concepts, yielding a promising new synthesis for describing scientific workflows, i.e., Collection-Oriented Modeling and Design (COMAD).

 

           12:30 - 13:00  J. Taylor “Triana Generations

 

Abstract This talk discusses the Triana workflow system within the context of the workflow community at large. It provides a brief background for Triana and discusses the ways in which is has been used in the past for serial and as-well-as distributed tasks. A brief overview of other environments is given followed by a description of the Triana distributed architecture and a discussion of its key features, being: its user interface and its ability to work simultaneously in heterogeneous distributed environments. The high-level Grid and service-based interfaces that enable this support are outlined along with their corresponding bindings to the underlying middleware, such as WSPeer, Jxta, P2PS, Globus and Web and WS-RF services. New directions are given for Triana within the peer-to-peer context, followed by a description of two current uses for this technology and two collaborations, which are providing distributed P2P simulations to help test our P2P overlays for massively distributed processing and searching before deployment.

 

  W21b: (Maurits room ) 14:30 - 16:00

 

           14:30 - 15:00 P. Rice “EMBRACE: Bioinformatics data and analysis tool services for e-Science”

          

Abstract—The EMBRACE project is a network of European partners providing services which integrate the major data resources and analysis software tools using web services and emerging grid technologies. Prototype services are available for the core data resources and the most commonly used tools for sequence analysis. Data access uses the WSDbFetch and BioMart services from the European Bioinformatics Institute. Software tool services use the SoapLab services, also from the European Bioinformatics Institute. The preferred client for these services is Taverna from the myGrid project. Subprojects are collecting and analyzing biological use cases, and maintaining a watch on emerging grid technology in Europe.

 

15:00 - 15:30 D. KönigWeb Services - Business Process Execution Language (WS-BPEL) 2.0

 

Abstract— Business  Processes  not  only  play  a key role in Business-to-Business (B2B) and Enterprise Application Integration (EAI) scenarios by exposing   the  appropriate  invocation  and  interaction patterns but they are the fundamental   basis   for   building   heterogeneous   and   distributed applications (workflow-based applications). Web Services Business Process Execution Language (WS-BPEL) provides the language to specify business processes that are composed of Web services as well as exposed as Web services. Business Processes specified via WS-BPEL are portable and can be carried out by every WS-BPEL compliant execution environment. This presentation gives an overview of the WS-BPEL language and shows how it can be used to compose Web services. It provides highlights of WS-BPEL, including structured activities, correlation, compensation, and fault handling. Finally, the OASIS WS-BPEL Technical Committee work, the current status of the standard, and an outlook on follow-on activities is presented.
