Durham DiRAC-2 petascale facility support

这笔拨款是为了支持已建立的达勒姆Petascale设施。千兆级设施的设计是为了实现数据密集型科学“大挑战”计算，解决一系列科学问题，包括宇宙学、恒星形成和磁流体动力学以及DiRAC设施科学计划的其他领域。资源将提供给同源科学学科的“大挑战”项目，这些项目使用相关的计算技术并具有共同的硬件和软件要求。详细信息见附于此表格的商业案例，该案例于2011年11月提交给STFC，并于2011年11月21日在莱斯特大学举行的DiRAC项目管理委员会会议上进行了讨论。

The grant is to support the established Durham Petascale facility. The petascale facility is designed to enable data intensive science "Grand Challenge" calculations tackling a range of scientific problems in fields including cosmology, star formation and magnetohydrodynamics and other areas of the science programme of the DiRAC facility. Resources would be offered to "Grand Challenge" projects in cognate scientific disciplines that use related computational techniques and have common hardware and software requirements. Details are provided in the Business Case attached to this form which was submitted to STFC in November 2011 and discussed at the meeting of the DiRAC Project Management Board held at Leicester University on 21/Nov/2011.
