Workshop on Workflows in Support of Large-Scale Science
In conjunction with HPDC 2006, June 20, Paris, France
Call for Papers
In recent years workflows have emerged as a key technology that enables large-scale
computations on distributed resources. Workflows enable scientists to design
complex applications that are composed of individual application components or
services. Often times these components and services are designed, developed,
and tested collaboratively. Because of the size of the data and the complexity
of the analysis, large amounts of shared resources such as clusters and storage
systems are being used to store the data sets and execute the workflows. The
process of workflow design and execution in a distributed environment can be
very complex and involve mapping high-level workflow descriptions onto the
available resources, as well as monitoring and debugging of the subsequent
execution. Because computations and data access operations are performed
on shared resources, there is an increased interest in managing the fair
allocation and management of those resources at the workflow level.
Adequate workflow descriptions are needed to support the complex workflow
management process which includes workflow creation, workflow reuse, and
modifications made to the workflow over time-for example modifications to the
individual workflow components. Additional workflow annotations may provide
guidelines and requirements for resource mapping and execution.
Large-scale scientific applications pose several requirements on the workflow
systems. Besides the magnitude of data processed by the workflow components,
the resulting and intermediate data need to be annotated with provenance information
and any other information needed to evaluate the quality of the data and
support the repeatability of the analysis.
The Workshop on Workflows in Support of Large-Scale Science focuses on the
entire workflow lifecycle including the workflow composition, mapping, and
robust execution. The workshop also welcomes contributions in the applications
area, where the requirements on the workflow management systems can be derived.
The topics of the workshop include but are not limited to:
*
Workflow applications and their requirements
*
Workflow representations, including semantic workflow descriptions
*
Applying business workflows to the scientific domain
*
Workflow composition, tools and languages
*
Workflow user environments, including portals
*
Workflow refinement tools that can manage the workflow mapping process
*
Workflow execution in distributed environments
*
Workflow fault-tolerance and recovery techniques
*
Data-driven workflow processing
*
Adaptive workflows
*
Workflow monitoring
*
Workflow optimizations
*
Performance analysis of workflows
*
Workflow debugging
*
Workflow provenance
*
Interleaving workflow creation and execution
*
Interactive workflows
Papers submitted to this
workshop should be in IEEE format

and no longer than 10 pages. The papers should be original and not
previously published. Papers will be refereed and accepted on the basis
of their scientific merit and relevance to the workshop topics. Papers
presented at the workshop will be included in the HPDC 2006 proceedings CD
(pending final decision by HPDC). To submit the papers, please email a
PDF or Postscript to deelman@isi.edu by February 10, 2006.
Selected authors will be
invited to submit an extended version of the paper to a special issue of the
Scientific Programming Journal.
