GridPP4: The UK Grid for Particle Physics

该提案是应STFC 2009年的邀请而提交的，旨在为英国的大型强子对撞机数据开发提供和运营一个计算网格。目前的GridPP合作的成功将建立在此基础上，英国对2011年4月至2015年3月期间LHC数据生产的反应将是确保有一个可持续的基础设施提供“计算在LHC时代”我们建议将网格作为提供非常大规模的计算资源的主要机制，以英国粒子物理界。这个基础将巩固成功，并增加英国物理学家的发现潜力。我们将运营一个生产质量的网格，提供鲁棒性，规模和功能。该提案完全与国际项目相结合，我们必须利用这个机会，利用英国在几个领域已经建立的领导地位。粒子物理网格将成为英国国家电网基础设施（NGI）的核心部分，该基础设施将与欧洲电网倡议（EGI）集成，并将与美国和其他地方的电网互操作。该项目将在各个领域进行管理，并将履行英国对全球大型强子对撞机计算网格（wLCG）的承诺，并确保全球活动直接使英国受益。到2015年，英国电网基础设施的规模将扩大到40，000个核心，存储容量超过60 PetaB。这将使英国能够以具有国际竞争力的方式利用LHC独特的物理潜力。从2011年4月开始，一个为期四年的GridPP4项目总共需要2780万英镑。

This proposal, submitted in response to the 2009 invitation from STFC, aims to provide and operate a computing Grid for the exploitation of LHC data in the UK. The success of the current GridPP Collaboration will be built upon, and the UK's response to production of LHC data in the period April 2011 to March 2015 will be to ensure that there is a sustainable infrastructure providing 'Computing in the LHC era' We propose to operate a Grid as the main mechanism for delivering very large-scale computational resources to the UK particle physics community. This foundation will underpin the success and increase the discovery potential of UK physicists. We will operate a production-quality Grid, delivering robustness, scale and functionality. The proposal is fully integrated with international projects and we must exploit the opportunity to capitalise on the UK leadership already established in several areas. The Particle Physics Grid will form a central part of the UK National Grid Infrastructure (NGI) that will be integrated with the European Grid Initiative (EGI) and which will inter-operate with Grids in the United States and elsewhere. The project will be managed across various domains and will deliver the UK's commitment to the worldwide LHC Computing Grid (wLCG) and ensure that worldwide activities directly benefit the UK. By 2015, the UK Grid infrastructure will have expanded in size to 40,000 cores, with more than 60 PetaBytes of storage. This will enable the UK to exploit, in an internationally competitive way, the unique physics potential of the LHC. A total request is made for £27.8m for a four year GridPP4 project starting in April 2011.
