机群分布式并行计算是当前最重要的一种网络计算模式,文章改变以往复杂的建设集中管理式系统的思维方式,提出了一种以用户为中心的动态非专用机群系统VDPC,论述了VDPC主要组件和工作原理,定义了交互消息格式和消息集,在Linux环境下设计实现了一个最小系统,可提供一组基本的系统管理工具和命令支持机群计算应用。讨论了VDPC的工作流图、设计和工作过程,并给出了系统测试结果。 Cluster distributed parallel computing is the most important network computing model at present. In this paper, changing the way of thinking of building centralized management system in the past, this paper proposes a user-centric dynamic non-dedicated cluster system (VDPC) Components and working principle, defines the interactive message format and message set, in the Linux environment design and implementation of a minimum system that provides a set of basic system management tools and commands to support cluster computing applications. The workflow diagram, design and working process of VDPC are discussed, and the system test results are given.
