传统的网格Portal大多不能很好地满足用户同时提交多作业的需求。本文提出了一个支持批量作业提交、可动态精确授权的网格计算门户。提供了简单易用的作业管理系统,支持作业的批量提交、作业状态的实时查看、作业的批量重做及终止、结果文件批量下载等功能;实现了基于LDAP的全网格用户认证及管理;根据批量提交的特点设计了基于组和个数受限应用规则结合的访问控制机制,实现了动态、精确的应用授权。分析及实验表明,用户通过该Portal能够高效、安全的完成计算任务。
Most of the traditional grid Portal can not meet the needs of users to submit multiple jobs at the same time. This article presents a grid computing portal that supports batch job submission and dynamic, precise authorization. Provides a simple and easy to use job management system to support batch submission of jobs, real-time view of job status, batch redo and termination of jobs, bulk download of result files and other functions; to achieve full grid LDAP-based user authentication and management; According to the characteristics of batch submission, a set of access control mechanism based on the combination of group and number limited application rules is designed to realize the dynamic and accurate application authorization. Analysis and experiments show that users through the Portal can efficiently and safely complete the computing task.
