Comprehensive Analysis of Performance, Fault-Tolerance and Scalability in Grid Resource Management System

Abstract

The management of the large scale heterogeneous resources is a critical issue in grid computing. The resource management system (RMS) is an essential component of grids. To ensure the QoS of the upper layer service, it raises high requirement for the performance, fault-tolerance and scalability of RMS. In this paper, we study three typical structures of RMS, including centralized, hierarchical and peer-to-peer structures, and make a comprehensive analysis of performance, fault tolerance and scalability. We put forward the performance, fault tolerance and scalability evaluation metrics of the RMS, and give the mathematical expressions and detailed calculation processes. Besides, we make further discussions on the interactions of the performance, fault-tolerance and scalability, and make a comparison of the RMSs with the three typical structures. We believe that the results of this work will help system architects make informed choices for building the RMS.
