ABSTRACT
P2P Grids could solve large-scale scientific problems by using geographically distributed heterogeneous
resources. However, a number of major technical obstacles must be overcome before this potential can
be realized. One critical problem to improve the effective utilization of P2P Grids is the efficient load
balancing. This chapter addresses the above-mentioned problem by using a distributed load balancing
policy. In this chapter, we propose a P2P communication mechanism, which is built to deliver varied
information across heterogeneous Grid systems. Basing on this P2P communication mechanism, we
develop a load balancing policy for improving the utilization of distributed computing resources. We also
develop a P2P resource monitoring system to capture the dynamic resource information for the decision
making of load balancing. Moreover, experimental results show that the proposed load balancing policy
indeed improves the utilization and achieves effective load balancing.
INTRODUCTION
boundary. In grid systems, the most important
issues include how to integrate the dynamically
heterogeneous distributed resources, and how
to improve the utilization of these integrated
resources (Dandamudi, 1995). Although these
various grid projects aim at sharing distributed
resources from different virtual organizations
(VOs), it is still difficult to share distributed
Recently, grid computing is one of attractive
architectures for high-performance computing.
The grid computing system is an Internet-scale
distributed computing system for sharing distrib-
uted resources across the traditional organization
