工作站机群系统已成为并行处理发展的主流方向之一 .随着机群系统应用领域的逐渐拓展和规模的不断扩大 ,人们对其可用性的要求日益提高 .设计高可用的机群系统 ,需要着重研究其系统重构技术 .本文主要论述工作站机群系统重构模型、系统状态的保存及恢复、故障的检测等关键技术 ;并结合我们开发研制的ChaRM(Checkpoint-basedRollbackRecoveryandMigrationSystem)系统 ,介绍工作站机群重构机制的设计与实现技术 .
Workstation cluster system has become one of the main trends in the development of parallel processing.With the gradual expansion of the field of application of the cluster system and its ever-expanding scale, people are increasingly demanding its availability.Highly available cluster system design needs to focus on its system Reconstruction technology.This paper mainly discusses the workstation cluster system reconfiguration model, the preservation and recovery of system state, fault detection and other key technologies; and combined with our developed ChaRM (Checkpoint-basedRollbackRecoveryandMigrationSystem) system, introduces the workstation cluster reconfiguration mechanism design With the realization of technology.
