GridPP4: The UK Grid for Particle Physics

这项提案是应2009年STFC的邀请提交的，旨在为利用英国的大型强子对撞机数据提供和运营一个计算网格。当前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月期间产生的大型强子对撞机数据的反应将是确保有一个可持续的基础设施来提供‘大型强子对撞机时代的计算’我们建议将网格作为向英国粒子物理界提供超大规模计算资源的主要机制。这一基础将为英国物理学家的成功奠定基础，并增加他们的发现潜力。我们将运营一个生产质量的网格，提供健壮性、规模和功能。该提议与国际项目完全融合，我们必须利用这个机会，利用英国在几个领域已经确立的领导地位。粒子物理网格将形成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)整合，并将与美国和其他地方的电网互操作。该项目将跨多个领域进行管理，并将兑现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造福于英国。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 PB。这将使英国能够以具有国际竞争力的方式利用大型强子对撞机的独特物理潜力。从2011年4月开始的为期四年的GridPP4项目总共申请2,780万GB。

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.
