Globus has become a standard in the construction of Grid computing environments. However, it still needs more work and research to satisfy requirements from various grid applications such as workflow services. We propose a Meta Scheduling Framework (MSF) for workflow service management based on the Globus toolkit. The MSF provides an XML-based Job Control Markup Language (JCML) for describing i...

In recent years, scientists from many domains have discovered Grid technology which offers new possibilities for solving problems that are difficult to handle with traditional distributed computing. In the first part of this thesis we examine the process to enable life science applications for execution on the Grid. Such applications often require the analysis of very large data sets and consis...

A transactional workflow is composed of traditional flat transactions, and its execution has relaxed transactional atomicity. Due to different termination characteristics of transactions, a transactional workflow may be not wellformed. Moreover, only one workflow is allowed to execute a non-compensatable transaction with current scheduling protocol. In this paper, we present a transactional wor...

Cloud computing is an emerging computing paradigm that can offer unprecedented scalability and resources on demand, and is gaining significant adoption in the science community. At the same time, scientific workflow management systems provide essential support and functionality to scientific computing, such as management of data and task dependencies, job scheduling and execution, provenance tr...

As the complexity of Grid applications increase, it becomes more important and urgent to provide grid workflow to construct and manage the applications. The grid workflow based on dynamic scheduling and performance evaluation is presented in this paper according to the standards of GCC and WFMC, which consists of user portal, resource management component, grid services management, performance ...

Workflows are modeled as hierarchically structured directed acyclic graphs in which vertices represent computational tasks, referred to as requests, and edges represent precedent constraints among requests. Associated with each workflow is a deadline that defines the time by which all computations of a workflow should be complete. Workflows are submitted by numerous clients to a scheduler that ...

Cloud computing sets a domain and application-specific distributed environment to distribute the services resources among users. There are numerous heterogeneous VMs available in handle user requests. The requests defined with specific deadline. scheduling methods set up order of request execution cloud environment. divided into two main categories called Task Workflow Scheduling. This paper, i...

Data transferring in scientific workflows gradually attracts more attention due to large amounts of data generated by complex scientific workflows will significantly increase the turnaround time of the whole workflow. It is almost impossible to make an optimal or approximate optimal scheduling for the end-to-end workflow without considering the intermediate data movement. In order to reduce the...

Cloud computing is one of the upcoming latest new computing paradigm where applications and data services are provided over the Internet. Today‘s most of the business organizations and educational institutions use cloud environment. The Task management is the key role in cloud computing systems task scheduling problems are main which relate to the efficiency of the whole cloud computing facilit...

Due to the distributed nature of data and the need for high performance, it makes Grid a suitable environment for distributed data mining. Since distributed data mining applications are typically data intensive, one of the main requirements of such a DDM Grid environment is the efficient workflow scheduling. We propose an architecture for a Knowledge Grid scheduler that results in the minimal r...
