论文摘要
在仿真与建模领域,仿真资源的数据密集型存储和海量数据检索,制约着分布式仿真与建模技术的发展。而云计算作为信息领域的热点,为云端用户分别提供基础设施即服务IaaS、平台即服务PaaS和软件即服务SaaS的能力。利用云计算平台的海量数据分布式存储能力和集群并行计算能力,将仿真资源的存储、管理与云计算技术相结合,是仿真资源管理发展的趋势。本文以仿真资源的特点、Eucalyptus云计算平台、Java内容仓库技术和LDAP目录服务,设计了在网络环境下以LDAP、Jackrabbit、Walrus为技术中心,将仿真资源通过Jackrabbit对Walrus的底层封装存储到Eucalyptus云计算平台的研究与实现。本文提出的仿真资源云存储是利用Eucalyptus云计算平台的简单存储服务Walrus和Jackrabbit技术,将仿真资源管理从单机或分布式集群迁移到云计算平台。为仿真用户提供基于Jackrabbit和Walrus的仿真资源注册和检出服务,基于LDAP的仿真资源目录服务和元数据检索服务。仿真资源云存储基于J2EE开发,实现了将云计算技术应用到仿真资源管理上的要求,达到了仿真资源的高吞吐率访问和集群分布式检索的要求。
