The Study of Centralized Load Balance on Distributed Shared Memory Systems

Abstract

Distributed Shared Memory facilities programmers with the similar programming interface of shared memory. However, it suffers the problem of load imbalance expecially when the composite computers are not equipped with the same class of processor or when the workload of program is nto partitioned equally among tasks. As a result, it is urgent to achieve load balance on a DSM system. In this thesis, we design a centralized dynamic load balance mechanism for an available software DSM system and the experiments show that it improvers the system performance significantly over that with no load balance involved.
