Accessibility algorithm based on site availability to enhance replica selection in a data grid environment
A data grid functions as a scalable base for grid services to manage data files and their scattered replicas around the world. The principal objective of grid services is to support various data grid applications (jobs) as well as projects. Replica selection is an essential high-level service that selects a Grid location which verifies the shortest response time for the users' jobs among numero...
متن کاملA New Job Scheduling in Data Grid Environment Based on Data and Computational Resource Availability
Data Grid is an infrastructure that controls huge amount of data files, and provides intensive computational resources across geographically distributed collaboration. The heterogeneity and geographic dispersion of grid resources and applications place some complex problems such as job scheduling. Most existing scheduling algorithms in Grids only focus on one kind of Grid jobs which can be data...
متن کاملReliability and Availability Improvement in Economic Data Grid Environment Based On Clustering Approach
Abstract - One of the important problems in grid environments is data replication in grid sites. Reliability and availability of data replication in some cases is considered low. To separate sites with high reliability and high availability of sites with low availability and low reliability, clustering can be used. In this study, the data grid dynamically evaluate and predict the condition of t...
متن کاملReplica Replacement Algorithm for Data Grid Environment
Grid computing is one of the fastest emerging technologies within the high performance computing environment. Grid deployments that require access to and processing of data are called data grids. They are optimized for data oriented operation. In a data grid environment, data replication is an effective way to improve data accessibility. However, due to limited storage, a replica replacement st...
