The booming industry of cloud computing encourages more and more people to put various types of data into the cloud. It results in a more frequent access to the data that stored in the cloud. Scheduling these requests to ensure the performance of cloud storage and the satisfaction of users becomes the key issue in cloud computing. Unfortunately, existing work mainly focus on task scheduling and resource...
In recent years, cloud computing has emerged as an enabling technology, in which virtual machine migration and dynamic resource allocation is one of the hot issues. During the migration of virtual machine, access requests from end users coming constantly. So how to schedule these requests to ensure the performance of cloud storage system is the key issue. In this paper, we focus on scheduling access...
In cloud computing era, datacenter can be organized by resources distributed geographically on demand into a dynamic logical entity. All these virtualized datacenters (VDCs) migrate transparently to another resources set for the best cost-effectiveness. Open storage architecture is one of the basic infrastructures in Cloud. This paper introduces a scheduling model of access request in open storage...
Job shop scheduling problem is a typical NP-hard problem, most of the existing researches of job-shop scheduling have the following problems: firstly, took various processing parameters of the production systems as the exact uncertainty value; Secondly, took production system as a static system, ignored a variety of unexpected situations of the actual processing. This paper started from the actual...
The tasks scheduling model is established based on multi-factors that include communication abilities between any two sites, process ability of the site and the reliability of site in complex and dynamic environment. The Target heuristic function is constructed combined minimum executing time and reliability of site. Simulation result demonstrates the factors concern with task scheduling model accord...
