IEEE 2009 Third International Workshop on Scientific Workflows (SWF 2009)

In conjunction with
7th IEEE International Conference on Web Services (ICWS 2009)
July 10, 2009, Los Angeles, CA, USA

Call for Papers

Today, many scientific discoveries are achieved through complex and distributed scientific computations that are represented and structured as scientific workflows. User friendly scientific workflow systems are increasingly being developed to enable e-scientists to integrate, structure, and orchestrate various local or remote data and service resources to perform various in silico experiments to produce interesting scientific discovery. The critical role of scientific workflows in cyberinfrastructure has been recognized by a recent NSF workshop on the challenges of scientific workflows in May 2006, which concluded that “workflows should become first-class entities in cyberinfrastructure architecture. For domain scientists, they are important because workflows document and manage the increasingly complex processes involved in exploration and discovery through computations. For computer scientists, workflows provide a formal and declarative representation of complex distributed computations that must be managed efficiently through their lifecycle from assembly, to execution, to sharing.”

The Third International Workshop on Scientific Workflows will expand the scope of the workshop to focus on the increasing convergence of developing concepts and tools in the areas of workflow, information flow, streams, and events.  Several concrete efforts have made progress towards this convergence, including data-driven workflows and asynchronous workflows.  The goal of the workshop is to bring together researchers from these originally separate areas to discuss the opportunities and challenges that arise from the convergence.  The discussion will cover a wide range of topics that link these areas, including applications in scientific and business workflows, workflow platforms, and tools and infrastructure for workflow specification, execution, and monitoring. 

The workshop will emphasize interactions through panel sessions in which panelists from different areas give short position presentations, followed by a discussion with workshop participants.  Potential panelists are encouraged to submit short position papers (one to three pages).   Current panel topics being considered include the discussions on research opportunities and challenges of convergence from different starting points (represented by panelists from these areas). 

  • Convergence by building on a primary area, with one panelist on traditional workflow concepts and tools (process-oriented view), one panelist on information flow concepts applied to workflow (data-driven and data-based views), and one panelist on event and stream-based concepts (event-driven and stream-oriented views).
  • New applications that require the convergence: cyber physical systems that link real-time data from sensor networks to large scientific models in data centers and cloud computing environments; integrated health monitoring and delivery; sustainable and energy-efficient processes in scientific and engineering applications.
  • Old challenges that the convergence can address better.  For example, exception handling has been a difficult problem for practical, large-scale workflows in both scientific and business applications.  Quite often, exceptions are handled by humans (very inefficiently).  Could the convergence bring in new perspectives to help solve the problems that exception handling is supposed to address, e.g., automated restoration of data to a consistent state after exceptions? 
Authors are invited to submit regular papers (8 pages), short papers (4 pages), and demo papers (2 pages) that show original unpublished research results in all areas of scientific workflows. Topics of interest are listed below; however, submissions on all aspects of scientific workflows are welcome. For demo papers, at least one author is expected to present a demo in the workshop during the demo session, special arrangement will be made to meet the need of the authors. 

Topics of interest include but not limited to:
  • Architecture, model, and language
  • Provenance management
  • Task management
  • Workflow scheduling
  • Data product management
  • Monitoring and failure handling
  • Service, Grid, and Cloud  workflows
  • Scientific workflow composition
  • Scientific workflow security
  • Modeling, simulation, analysis
  • Scalability, reliability, extensibility
  • Scientific workflow applications
