Provision of Tier-2 computer hardware and system support from Sept 2007 to March 2011.

网格是正在建设的世界范围的计算系统，以提供分析由欧洲核子研究中心的新型大型强子对撞机(LHC)获取的数据所需的计算能力，该对撞机于2007年开始运行。这种计算能力分布在大型中央集群(Tier-1)中，并基于各个大学系(Tier-2)。将需要数十万台计算机。一切都是通过互联网连接在一起的，作业以一种最有效地使用计算机的方式自动运行。

The GRID is the world-wide computing system being constructed to provide the computing power needed to analyse the data being taken with the new large hadron collider (LHC) based at CERN that starts running in 2007. This computing power is spread over large central clusters (Tier-1) and based in individual University departments (Tier-2). Hundreds of thousands of computers will be needed. Everything is connected together using the Internet and jobs are run automatically in such a way that the computers are used in the most efficient manner.
