集群的监控和管理工具多种多样，设计方法也有很多，本文综合国内外多种集群系统的性能检测工具设计方法的优点，结合面向对象设计思想，主要对Infiniband 网络性能监控和并行程序监控进行改进，在Redhat Linux 系统下使用C 语言和QT 实现可视化的图形监控和管理工具。关键词: InfiniBand 集群 系统监控 网络监控 libp_cap【ABSTRACT】Monitoring and management tools of clusters are diverse, and theirdesigns are also various. This article unites many good designs of clusterperformance monitoring system with object-oriented programming. It is improved onInfiniBand network performance monitoring and parallel program monitoring, what isdeveloped to be a graphical monitoring and management tool with C and QT in RedhatLinux system.【KEYWORDS】InfiniBand, cluster, System monitoring, network monitoring, libp_cap
