GridFlow: Workflow Management for Grid Computing Kavita Shinde.

Three fundamental dimensions of scientific workflow interoperability: Model of computation, language, and execution environment. The workflow paradigm is a highly successful paradigm for the creation of Grid applications.

Despite the popularity of the workflow approach, the systems that support the execution of workflow applications gridfliw Grid environments are still Despite the popularity of the workflow approach, the systems that support the execution of workflow applications in Grid environments are still not able to deliver the quality, robustness and reliability that their users require and demand.

To understand the current state-of-the-art and gridfloa reasons behind the. Large-scale scientific workflows are executed on complex parallel and distributed resources, where many things can fail. Application scientists worlflow to track the Application scientists need to track the status of their workflows in real time, detect execution anomalies automatically, and perform troubleshooting — without logging into remote grir or searching through thousands of log files. We use these detected failures to derive higher-level statistics about the status of the resources and the workflow as a whole.

In this paper, we describe our techniques and evaluate their effectiveness in the context of real application logs. An uncoordinated asynchronous checkpointing model for hierarchical scientific workflows. Adaptive exception handling for scientific workflows.

Job submission in gLite is done by the Workload Management System WMS [12]; it comprises a set of Grid middleware components responsible for the computinf and man-agement of tasks across Grid resources.

Service-Oriented Architectures SOA transform the ways in which the applications are created in a distributed environment work. Commonly, these applications are based on Web Services technologies. Web Services allow integration and Web Services allow integration and collaboration through Internet standards. Collaborative Web Browsing co-browsing aims at extending currently available Web browsing capabilities in order to allow several users to ” browse together ” on the Web.

A co-browsing system should provide all the facilities required for allowing users to establish and release, in a very simple and flexible way, browsing synchronization relations as well as interactions with continuous media presentations embedded within Web worflow.

This paper presents the design, modeling, and implementation of the co-browsing system called CoLab from a point of view of SOA. CoLab provides all the functionalities required for allowing users to collaboratively browse the Web. CoLab presents a service-oriented architecture where the functionalities for co-browsing are performed. Analysing scientific workflows with Computational Tree Logic.

IT service infrastructure for integrative systems biology. Abstract Despite the large number of software tools and hardware platforms aiming to solve the problems that bioinformatics is facing today, there is no platform solution that managemeent scale up to its demands, in terms of both scope and sheer Abstract Despite the large number of software tools and hardware platforms compkting to solve the problems that bioinformatics is facing today, there is no platform solution that can scale up to its demands, in terms of both scope and sheer volume.

DiscoveryNet scientific workflow system is here extended into a service-centric component architecture that brings together cross-domain applications through Web and grid services and composes them as novel service offerings. Two case studies implemented on top of the platform, SARS Heterogeneous Workflows in Scientific Workflow Systems. Scientific workflow systems – can one size fit all? Polymorphic type framework for scientific workflows with relational data model.

Scientific workflow systems provide languages for representing worklow scientific processes as decompositions into lower level tasks, down to the level of atomic, executable units. To support data analysis activities, a wide variety of To support data analysis activities, a wide variety of such languages represent data transformation and processing operations as task nodes within a workflow.

Adding data type information to the task inputs and outputs allows workflow authors to perform type checking at design time, search for compatible nodes in public component repositories and define Towards a scientific workflow methodology for primary care database studies.

We describe the challenges of conducting studies based on mining large-scale primary care databases, namely data integration, data set definition, result reproducibility and reusability. These correspond to higher-level informatics These correspond to higher-level informatics challenges of automation, provenance capture and component integration. We provide a high-level view of the informatics infrastructure that addresses these challenges through a generic workflow-based e-Science middleware, and describe our experiences using the system to investigate differences in the health status of patients with diabetes before and after the national introduction of the UK GP contract in Abstract The avian flu grid is a virtual organization dedicated to the discovery of novel inhibitors for the pandemic avian flu threat, leveraging grid technologies and computational resources provided by PRAGMA and its partners.

In this context it is essential to adopt Automation and management of scientific workflows in distributed network environments. Abstract Large-scale computation-intensive applications in various science fields feature complex DAG-structured workflows comprised of distributed computing modules with intricate inter-module dependencies.
