从2008年年中开始，欧洲核子研究中心大型强子对撞机的ALICE探测器将以每年4PB的速度收集数据。ALICE将专门使用分布式网格资源来存储、处理和分析这些数据。网格资源的顶层管理是通过AliEn（ALICE环境）系统完成的，该系统自2000年以来一直在持续开发中。Alien提出了几个原创的解决方案，这些解决方案在一些称为数据挑战的日益复杂的大型练习中显示了其可行性。本文介绍了Alien的体系结构：作业管理，数据管理和用户界面。将说明Alien的当前状态，以及系统在数据挑战期间的性能。本文还描述了Alien未来的发展路线图。
Starting from mid-2008, the ALICE detector at CERN LHC will collect data at a rate of 4PB per year. ALICE will use exclusively distributed Grid resources to store, process and analyse this data. The top-level management of the Grid resources is done through the AliEn (ALICE Environment) system, which is in continuous development since year 2000. AliEn presents several original solutions, which have shown their viability in a number of large exercises of increasing complexity called Data Challenges. This paper describes the AliEn architecture: Job Management, Data Management and UI. The current status of AliEn will be illustrated, as well as the performance of the system during the data challenges. The paper also describes the future AliEn development roadmap.
