2nd Workshop on Workflows in Support of Large-Scale
Science (WORKS07)
In conjunction with HPDC 2007,
June 25 2007
Paper
submission deadline extended to February 17, 2007
Keynote Speaker: Carole Goble,
In recent
years workflows have emerged as a key technology that enables large-scale
computations on distributed resources. Workflows enable scientists to design
complex analysis 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
Second 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
*
Interleaving workflow creation and execution
*
Data-driven workflow processing
*
Adaptive workflows
*
Workflow monitoring
*
Workflow optimizations
*
Performance analysis of Workflows
*
Workflow debugging
*
Workflow provenance
*
Interactive Workflows
*
Relevance of Business Workflow Standards
