科学计算网格环境信息服务扩展研究

Research on extension of information services under scientific computing grid environment

为了更好地支持科学计算网格中资源共享的需求,在分析现有网格信息服务技术局限的基础上,根据科学计算程序资源的特点,提出了"服务组-物理服务"、"顾问服务"的思路来解决存在的问题。作为对现有信息服务技术的扩展增强,设计了一个三层服务信息组织架构和资源服务信息中心方案。试验结果表明,该设计方案可行,管理开销在合理范围内,较好地满足了构建科学计算网格环境的需要。

In order to support resource sharing requirement under scientific computing grid environment, based on analysis of the constraints of existing Grid information services technologies, the ideas of ＂service group concrete services＂ and ＂consulting service＂ are proposed to address the issues according to the characteristics of scientific computing code resources. As an extension to existing information services, a design scheme is put forward, consisting of 3-layered service information organization framework and resource service information center. Experimental results show the feasibility of the design scheme, and the management cost is within reasonable limits, which meets well the demands for building scientific-computing-oriented grid environment.
