摘要
机群操作系统面临着网格计算对其提出的资源共享、协同工作和自治管理的挑战 ,现有的扁平结构的机群操作系统不能够适应这种需求 .提出了一种基于服务的机群操作系统 DCOS,采用层次型结构和面向对象的设计思想 ,从多个角度为网格系统提供支持 .讨论了远程过程调用、系统状态侦测、实时检查点。
Grid computing issues new challenges as resource sharing, coordinate working and autonomous management to cluster operating system (cluster OS). The current cluster OS with flat structure can not meet the requirements. In this paper, we propose a service-based cluster OS, called DCOS, which adopts hierarchy architecture and object-oriented design, and somehow supports grid computing. Major key techniques as remote procedure invocation, system status detection, real-time check point and security facility are also disscussed.
