摘　　要：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。Traditional grid portal mostly could not give a solution to satisfy the users demand of submit massive jobs simultaneously. In this paper a grid portal supported job batch-submission and dynamic authorization is proposed. It supplied an easy-touse job management system, which supported job batch-submission, job state view in real time, job batch-redo and termination, output files batch-download. Moreover, it implemented user authentication and management based on LDAP, and according to batch-submission＇s character, designed an access control mechanism based on Group and Num-Limited Application Rule, which could authorize user of applications accurately. Analysis and test show that user can efficiently, securely submit computing tasks through this portal.
