科学计算环境提供了海量的计算资源和不同学科的大量应用,如何获取准确的信息并展示给用户和管理人员,是提高科学计算环境效率和易用特性必须解决的问题。本文在中国科学院科学环境中间件的基础上,研究和实现了基于REST风格的Web访问接口,提供用户、应用、资源和作业等信息的即时查询和指定条件下的信息统计服务。测试和实际应用表明,本文提出的Web信息服务,具有简单易用、功能全面、支持多平台和语言的特性,方便开发人员以丰富多样的形式展示科学计算环境的信息。
The scientific computing environment provides massive computing resources and a large number of applications in different disciplines. How to obtain accurate information and present it to users and administrators is a problem that must be solved to improve the efficiency and ease-of-use features of the scientific computing environment. On the basis of Chinese Academy of Sciences environment-based middleware, this paper studies and implements a REST-based Web access interface, providing instant information query of users, applications, resources and jobs, as well as information statistics services under specified conditions. Tests and practical applications show that the proposed Web information service is simple and easy to use, full-featured and supports multiple platforms and languages. It is convenient for developers to display scientific computing environment information in a variety of forms.
