A Grid Workflow is critical to grid computing for its ability of creating complex grid computation by connecting different grid jobs logically. User can easily define and reuse the workflow for their applications that are loosely coupled. In this paper, we proposed a Grid Workflow Management System (GWMS) to provide the interface of processing workflow with grid schedulers, e.g., Sun Grid Engin...

We introduce the ActivityFlow speciication language for in-cremental speciication and exible coordination of workkow activities. The most interesting features of the ActivityFlow speciication language include (1) a collection of speciication mechanisms, which provides a workkow designer with a uniform workkow speciication interface to describe diierent types (i.e., ad-hoc, administrative, or pr...

A workflow models a process as consisting of a series of steps that simplifies the complexity of execution and management of applications. Scientific workflows in domains such as high-energy physics and life sciences utilize distributed resources in order to access, manage, and process a large amount of data from a higher level. Processing and managing such large amounts of data require the use...

Within the BIS-Grid project, a BMBF-funded project in the context of the German D-Grid initiative, we developed the BIS-Grid workflow engine that is based upon service extensions to UNICORE 6 to use an arbitrary WS-BPEL workflow engine and standard WS-BPEL to orchestrate stateful, WSRF-based Grid services. Although aimed at proving the feasibility of applying Grid technologies for business info...

With the advent of Grid technologies, scientists and engineers are building complex and sophisticated applications to manage and process large data sets, and execute scientific experiments on distributed Grid resources [33]. Building complex workflows requires means for composing and executing distributed applications. A workflow expresses an automation of procedures wherein files and data are ...

Spacecraft software automatic testing plays an essential role in spacecraft testing field for a decade. However, less attention has been paid on it based on workflow methodology. In this paper we introduce workflow technology into testing for improving the automation of spacecraft software testing. Firstly we present a spacecraft testing process definition language STPDL. Then workflow patterns...

In BIS-Grid, a BMBF-funded project in the context of the German D-Grid initiative (http://www.d-grid.de), we focus on employing Grid technologies for information systems integration. The goal is to enable small and medium enterprises (SMEs) to integrate heterogeneous business information systems and to use external Grid resources and services with reasonable effort. To achieve this goal, we dev...

Scientists today are exploring the use of new tools and computing platforms to do their science. They are using workflow management tools to describe and manage complex applications and are evaluating the features and performance of clouds to see if they meet their computational needs. Although today, hosting is limited to providing virtual resources and simple services, one can imagine that in...

9.05 Information guided surgery using workflow descriptions Due to the variety of anatomy and pathology of patients, parameters and the structure of the surgical process vary greatly. Therefore, optimal usage of complex robot assisted surgical systems is currently limited by the lack of continuous information support. An patient related configurable workflow plan will be used as a reference. Ch...
