The 8th IEEE/ACM International Conference on Grid Computing, Grid2007
by Ewa Deelman 06 Mar '07

06 Mar '07

******************* Call for Papers ******************* (Grid 2007, http://www.grid2007.org) Austin, Texas, USA, September 19-21, 2007 Grid computing is evolving from the sharing of powerful computers for widely distributed applications to service orientation, open standards integration, collaboration, and virtualization. The ongoing development of the Grid as a service-oriented architecture for transparent and reliable distributed computing allows the reuse of existing components and information resources, and the assembly of these components in a flexible self-organizing manner. Hiding the complexity and technical details of the Grid from end users and application developers is going to play a crucial role in the future, for which issues related to security, provenance, automatic recovery, machine-interpretable metadata, QoS and SLA negotiation, etc. will have to be carefully addressed. The Grid conference series is an annual international meeting with the objective to serve as both, the premier conference presenting best Grid research and as a forum for free exchange of ideas. Grid 2007 will feature invited talks, workshops, tutorials, and refereed paper presentations where new concepts are introduced and explored. Topics of interest (in no particular order) include, but are not limited to: * Applications, including eScience and eBusiness Applications * Distributed and Large-Scale Data Access and Management * Computing and Programming Models * Programming Tools and Environments * Distributed Problem Solving * Creation and Management of Virtual Enterprises and Organizations * Information Services * Resource Management, Scheduling, and Runtime Environments * Architectures and Fabrics * Scientific, Industrial and Social Implications * Monitoring, Management and Organization Tools * Middleware and Toolkits * QoS and SLA Negotiation * Grid Economy and Business Models * Autonomic and Utility Computing on Global Grids * Cluster and Grid Integration Issues * Networking and Security * Performance Measurement and Modeling * Metadata, Ontologies, and Provenance **************** Important Dates **************** April 7, 2007 Deadline for full paper submission May 31, 2007 Acceptance notification June 22, 2007 Camera-ready copy due ****** News ****** Tony Hey from Microsoft and Carole Goble from University of Manchester will give keynote presentations in Grid2007. Paper submission is open now for Grid 2007. ***************** Technical Papers ***************** Grid 2007 invites authors to submit original and unpublished work (also not submitted elsewhere for review) reporting solid and innovative results in any aspect of grid computing and its applications. Papers should not exceed 8 single-spaced pages of text using 10-point size type on 8.5 x 11 inch paper (see IEEE author instructions (PDF), a LaTeX style sheet and Word format is available, too).

Special Issue on Dynamic Computational Workflows: Discovery, Optimization, and Scheduling
by Ewa Deelman 06 Mar '07

06 Mar '07

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 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: 16 April 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, 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.
