CROWN FlowEngine: A GPEL-Based Grid Workflow Engine

چکیده
Currently some complex grid applications developing often need orchestrate multiple diverse grid services into a workflow of tasks that can submit for executing on the grid environment. In this paper, we present CROWN FlowEngine—a GPEL-based grid workflow engine for executing grid workflow instances. Besides basic functions of a conventional BPEL4WSbased workflow engine, CROWN FlowEngine has many features including hierarchical processing mechanism, multiple types of task scheduling, transaction processing, etc, which are of paramount importance to supporting workflow instances using GPEL language. CROWN FlowEngine will be adopted and widely deployed in CROWN Grid environment to support a wide range of service grid applications integration. We conduct several experiments to evaluate the performance of CROWN FlowEngine, and the results of comparing our work with GWES are presented as well.

Architectural Plan for Constructing Fault Tolerable Workflow Engines Based on Grid Service
In this paper the design and implementation of fault tolerable architecture for scientific workflow engines is presented. The engines are assumed to be implemented as composite web services. Current architectures for workflow engines do not make any considerations for substituting faulty web services with correct ones at run time. The difficulty is to rollback the execution state of the workflo...

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...
متن کاملA Distributed Re-configurable Grid Workflow Engine
Grid workflow, as a basic service in the grid environment, is a useful tool to help researchers make use of various gird resources to solve scientific problems. It is possible lots of users invoke grid workflow services in a very narrow time interval. Therefore, a centralized grid workflow engine is apt to be a bottleneck. In the paper, a novel grid workflow engine is proposed. It is based on J...
