2nd Workshop on Workflows in Support of Large-Scale Science (WORKS07) In conjunction with HPDC 2007, Monterey Bay, CA June 25 2007 www.isi.edu/works07 Paper submission deadline extended to February 17, 2007 Keynote Speaker: Carole Goble, University of Manchester, UK 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 Important dates: Paper submission: Deadline extended to February 17, 2007 Acceptance notification: March 17, 2007 Final papers due: April 6, 2007 Papers submitted to this workshop should be in IEEE format (ftp://pubftp.computer.org/Press/Outgoing/proceedings/) and no longer than 10 pages.

Special Issue on Dynamic Computational Workflows: Discovery, Optimization, and Scheduling
by Ewa Deelman 30 Nov '06

30 Nov '06

SCIENTIFIC PROGRAMMING JOURNAL Call for Papers Special Issue on Dynamic Computational Workflows: Discovery, Optimization, and Scheduling Guest editors: David W. Walker, Cardiff University, UK Ewa Deelman, USC Information Sciences Institute, USA http://users.cs.cf.ac.uk/David.W.Walker/WOSE/CFP.pdf Scientific Programming invites the submission of papers for a special issue entitled Dynamic Computational Workflows: Discovery, Optimization, and Scheduling. Workflows are widely viewed as offering a useful representation of computational applications that are to be run in a distributed environment. A workflow can be conveniently displayed as a directed graph in which nodes represent services and edges represent the flow of data and/or control between them. Here the term "services" is used in a generic sense to refer to any sub-unit of computation - often these are implemented as large grain-size Web services or other application components. A dynamic workflow can be described as a workflow that may be changed after it has been designed, either at runtime or prior to invocation. Various opportunities exist for workflow optimisation, and this process is related to both service discovery and workflow scheduling. A common example of workflow optimization arises when multiple equivalent services are available to fulfil a service request. In such cases semantic support to recognise equivalent services is required. In general, a workflow may be composed of abstract services that get bound to concrete service implementations either when the workflow is initially designed, or at any subsequent time prior to service invocation. Three different types of binding abstract to concrete services can be distinguished. In early binding the service binding is done statically at design time and does not subsequently change. In late binding the service binding is done at runtime immediately before a service is to be invoked. In intermediate binding the service binding is done after the workflow is designed but before it is submitted for execution. Although a workflow may be optimised at any of these three stages, delaying the binding of a service as late as possible allows more recent information to inform the optimisation process. It also makes it more likely that unavailable services will not be selected. Late binding performs optimisation on a service-by-service basis. However, intermediate binding allows the workflow as a whole to be optimised, taking into account factors such as the bandwidth between connected nodes in the workflow graph, and opportunities for algorithmic optimizations. The special issue will focus on all aspects of dynamic workflows, including, but not necessarily be limited to, the following topics: · Predictive scheduling · Performance-based middleware · Semantic support for service selection · Web service discovery and optimisation · Workflow optimisation · Workflow restructuring It is anticipated that most of the papers comprising the special issue will present original and unpublished research results. However, review and work-in-progress papers will also be considered. Review papers should include cogent analyses of the relevant issues relating to dynamic workflows, as well as discussion of the technologies and application requirements driving this development. Work-in-progress papers should place the work presented in the context of a coherent program of research, and in relation to more general service-oriented workflow issues. Schedule and Deadlines The schedule for the publication of the special issue is as follows: 1 December 2006 Distribution of Call for Papers 16 March 2007 Deadline for submission of papers 31 May 2007 Notification of authors 27 July 2007 Final submission of accepted papers It is hoped that the special issue will appear before the end of 2007. Submission of Manuscripts Papers should be prepared in accordance with the instructions given at the Scientific Programming web site at http://www.iospress.nl/html/10589244_ita.html <http://www.iospress.nl/html/10589244_ita.html> , and submitted directly by email to one of the Guest Editors: David W. Walker (david(a)cs.cf.ac.uk) Ewa Deelman (deelman(a)isi.edu) For any further information about this special issue please contact either of the Guest Editors.

[wg-all] Mailing List Changes
by Andre Merzky 03 Sep '06

03 Sep '06

Sorry for duplicates ------------------------------------------------------------ As of yesterday, all GGF/OGF mailing lists are migrated to the ogf domain. They are now managed by mailman, the web interface is available at http://www.ogf.org/mailman/listinfo With that migration, all list can be now reached via <list>@ogf.org The old @ggf.org addresses will be available for some time, but are bound to disappear eventually - please start using the ogf addresses! A number of lists have changed their names: ggf-it --> ogf-it ggf-office --> ogf-office ggf-proc-wg --> ogf-proc-wg ggf-sponsors --> ogf-sponsors ggf-tutorials --> ogf-tutorials ggf-compute --> ogf-compute ggflistowners --> ogflistowners ggfstudentmembers --> ogfstudentmembers Postings to the old list names get forwarded to the new ones. With the migration we have also been able to fix the archives - you may have noticed that list archiving stopped sometime in mid June. Well, now its working again, and all mails from June to now have been added to the archive. The list archives can be found at: http://www.ogf.org/archives/<list> If you are an list administrator, and would like to receive the list admin password, please contact postmaster(a)ogf.org. In general, however, we tried to map the old majordomo settings to the mailman settings, in terms of privacy etc, so no or little changes should be required from your side. The spam avoidance policy has been changed to some extent, and is somewhat stricter than before. Please let us know if you experience any trouble with that. On all questions in respect to mailing lists, or mails in general, please contact postmaster(a)ogf.org. Best regards, Andre. -- "So much time, so little to do..." -- Garfield -- wg-all mailing list wg-all(a)ogf.org http://www.ogf.org/mailman/listinfo/wg-all

Panel on Workflow as the Methodology of Science at WORKS06 in Paris June 20th
by Ewa Deelman 02 Jun '06

02 Jun '06

Below is the information about the panel to be conducted during WORKS06 (Workshop on Workflows in Support of Large-Scale Science) in Paris in conjunction with HPDC. Panel on "Workflow as the Methodology of Science" Tuesday June 20 2006 WORKS Workshop HPDC Paris France 12pm - 1.30pm http://www.isi.edu/works06 Moderator Geoffrey Fox A recent NSF workshop http://vtcpc.isi.edu/wiki/index.php/Main_Page proposed that workflow could be viewed as underlying support for the scientific methodology emerging in many fields and involving distributed interdisciplinary data deluged scientific methodology as an end (instrument, conjecture) to end (publication, archived results) process. This vision for workflow mixes the coupled execution of related services characteristic of most scientific workflow with the more asynchronous longer term processes familiar in some business workflow. Can one usefully link these different styles of workflow and further enhance scientific productivity? One challenge is reproducibility of this full process which is core to the scientific method and requires rich provenance, interoperable persistent repositories with linkage of open data and publication as well as distributed simulations, data analysis and new algorithms. The distributed reproducible science methodology can be supported by publishing all steps in a sort of electronic logbook that is the "script" of the full scientific workflow. It would need to capture the scientific process (data analysis) as a rich cloud of resources including emails, presentations, wikis as well as databases, compiler options, build time/runtime configurations etc. One could need to separate wheat from chaff in this electronic record (logbook) keeping only that required to make process reproducible and allowing selective execution (checking) of components of the log. Is this a reasonable picture for a future workflow requirement and what are the new research challenges it engenders? The presentations at NSF meeting can be found at http://vtcpc.isi.edu/wiki/index.php/Documents and give us a starting point! Contributors: E. Deelman Summary of NSF Workshop S.

Hi, This is a reminder that early registration deadline is May 19th. -Ewa ________________________________ From: owner-wfm-rg(a)ggf.org [mailto:owner-wfm-rg@ggf.org] On Behalf Of Ewa Deelman Sent: Wednesday, April 19, 2006 11:28 AM To: wfm-rg(a)ggf.org Subject: [wfm-rg] WORKS06 Call for Participation Workshop on Workflows in Support of Large-Scale Science June 20, Paris, France In conjunction with HPDC 2006 <http://hpdc.lri.fr/index.php?section=General&subsection=Home> www.isi.edu/works06 Call for Participation 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 program will consist of paper presentations and a panel on the Relationship of Workflow and Distributed Programming and Scripting.
