This paper describes the architecture for transparently using several di erent Cloud Resources from with the graphical Kepler Worklfow environment. This architecture was proven to work by implementing and using it in practice within the FP7 project EUFORIA. The clouds supported are the Open Source cloud environment OpenNEbula (ONE) and the commercial Amazon Elastic Compute Cloud (EC2). Subseque...

Abstract Tillage is the most energy-intensive process and should be aimed at accumulation of humus formation a fertile soil layer. Therefore, development resource-saving technological processes technical means to stop progressive degradation from wind, water erosion reduce operating costs relevant. The gentle cultivation with less energy allows you perform disk implements. cultivator working ex...

 To use services transparently in a distributed environment, the Utility Grids develop a cyber-infrastructure. The parameters of the Quality of Service such as the allocation-cost and makespan have to be dealt with in order to schedule workflow application tasks in the Utility Grids. Optimization of both target parameters above is a challenge in a distributed environment and may conflict one an...

Reusable development can promote the productivity of large workflow systems development. However it has not precluded developers from designing workflow system tailoring to users’ specific needs, though workflow management coalition standardized the five kinds of abstract interfaces of workflow enactment service in workflow reference model. Specific business process characteristics are still su...

This paper presents a workflow validation method for data-intensive graphical workflow models using real-time workflow tracing mode on data-intensiveworkflow designer. In order to model and validate workflows, we try to divide as modes have editable mode and tracingmode on data-intensiveworkflow designer. We could design data-intensive workflow using drag and drop in editable-mode, otherwise we...
