GridPP4+ Edinburgh one year extension for staff support

这项提案是应2014年STFC的邀请提交的，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。当前GridPP合作的成功将建立在此基础上，英国对2015年4月至2016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，提供“大型强子对撞机时代的计算”。我们建议运营一个网格，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。这一基础将支持英国物理学家的成功并增加发现潜力。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结合，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。粒子物理网格将越来越多地与国家和国际倡议相结合。该项目将跨多个领域进行管理，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英国。到2015年，英国网格基础设施的规模将扩大到50,000个核心，具有超过30 PB的存储空间。这将使英国能够以具有国际竞争力的方式开发大型强子对撞机的独特物理潜力。

This proposal, submitted in response to the 2014 invitation from STFC, aimsto provide and operate a computing Grid for the exploitation of LHC data inthe 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 2015 toMarch 2016 will be to ensure that there is a sustainable infrastructureproviding "Computing in the LHC era"We propose to operate a Grid as the main mechanism for delivering verylarge-scale computational resources to the UK particle physics community.This foundation will underpin the success and increase the discoverypotential of UK physicists. We will operate a production-quality Grid,delivering robustness, scale and functionality. The proposal is fullyintegrated with international projects and we must exploit the opportunityto capitalise on the UK leadership already established in several areas. TheParticle Physics Grid will increasingly be integrated with national andinternational initiatives.The project will be managed across various domains and will deliver the UK'scommitment to the Worldwide LHC Computing Grid (WLCG) and ensure thatworldwide activities directly benefit the UK.By 2015, the UK Grid infrastructure will have expanded in size to 50,000cores, with more than 30 PetaBytes of storage. This will enable the UK toexploit, in an internationally competitive way, the unique physics potentialof the LHC.
