Computational science increasingly relies on the execution of workflows in distributed networks to solve complex applications. However, the heterogeneity of resources in these environments complicates resource management and the scheduling of such applications. Sophisticated scheduling policies are being developed for workflows, but they have had little impact in practice because their integration...
Based on the concept of multi-project management, it is pointed out that the key to multi-project management of real estate enterprises is to solve the strategic problems, resource problems and coordination problems. The functions of the project management office is evolved with the specific needs of enterprise project management, this paper will introduce the organizational form of Project Management...
Typical remote sensing image interpretation consists of large number of long-lived independent computation jobs such as calibration, correction, and transformation and computation. These time consuming jobs are suitable for execution in desktop grid with high performance commodity PCs for its lower cost and high management ability. In this paper, a framework of parallel remote sensing image interpretation...
Cloud computing, as an emerging computing model, is drawing much attention from academia and industry. Storage resource, computing resource and network resource are three basic resources in a cloud computing infrastructure. How to utilize these resources efficiently and conveniently is a big challenge for building a good cloud computing infrastructure. This paper presents a service-oriented storage...
Virtualization technology has attracted wide attention in recent years as a method to improve resource utilization, reduce costs, and ease server management. However, the performance penalty resulting from virtualization is an unneglectable problem and should be carefully evaluated. To our knowledge, there are few performance evaluating tools developed for virtualization environments. We propose a...
Workflow Management System is a software system that runs on one or more work flow engines that used to define, implement and manage the workflow, interacts with workflow executors, facilitates the workflow instancepsilas execution and monitors the state during the workflow execution. Mobile Agent system supporting workflow management can make the distributed workflow in OA System more simple and...
Resource-sharing is one of the grid intrinsic properties enabling efficient usage of services by clients from many virtual organizations. In such an environment, the provisioning of quality of service requires mechanisms for the control of the concurrent access to resources and services, as well as protocols for the establishment of service level agreements between users and service providers. Nevertheless,...
