自ALICE实验于2010年初开始数据采集以来，AliEn网格上的最终用户工作数量显著增加。目前，ALICE可用的40K CPU内核中有1/3被大约400个不同用户提交的作业占用，这些用户单独或有组织地进行分析。在3年的运行中，AliEn中间件的整体稳定性一直非常出色，但是大量的终端用户分析及其特定的需求和负载显示出可以改进的组件很少。其中之一是用户和中央AliEn服务（目录、作业提交系统）之间的接口，我们目前正在用Java重新实现。该接口提供持久连接，增强了数据和作业提交的真实性。在本文中，我们将描述新接口的体系结构，即ROOT绑定，除了标准的类unix访问外壳和新的安全相关特性之外，它还支持使用单个接口。
Since the ALICE experiment began data taking in early 2010, the amount of end user jobs on the AliEn Grid has increased significantly. Presently 1/3 of the 40K CPU cores available to ALICE are occupied by jobs submitted by about 400 distinct users, individually or in organized analysis trains. The overall stability of the AliEn middleware has been excellent throughout the 3 years of running, but the massive amount of end-user analysis and its specific requirements and load has revealed few components which can be improved. One of them is the interface between users and central AliEn services (catalogue, job submission system) which we are currently re-implementing in Java. The interface provides persistent connection with enhanced data and job submission authenticity. In this paper we will describe the architecture of the new interface, the ROOT binding which enables the use of a single interface in addition to the standard UNIX-like access shell and the new security-related features.
