Gateways to Discovery: Cyberinfrastructure for the Long Tail of Science

加州大学圣地亚哥分校（University of California at San Diego）将提供一种突破性的新型计算设备Wildfire，该设备将提供给研究社区，既有高端计算（HEC）的成熟用户，也有不太熟悉HEC如何推进其科学和工程目标的新用户社区。Wildfire的显著特点是：(i)为98%的XSEDE作业（50%的XSEDE核心小时）提供1.8-2.0 Petaflop/s的长期寻求容量，这些作业使用的内核少于1000个，同时也支持更大的作业。确切的数字将取决于英特尔提供的处理器的速度，但不能低于1.8千万亿次/秒。（ii）在200gb /s带宽下为scratch和allocated Storage提供7pb基于lustret的Performance Storage，以及6pb的Durable Storage（iii）在早期部署的系统（如Trestles和Gordon）上使用经过验证的策略，通过分配/调度确保高吞吐量和响应能力（iv）建立一个快速访问队列，在请求的一天内提供新帐户(v)通过虚拟化为不熟悉的社区启用社区支持的自定义软件堆栈与HPC环境。这些虚拟集群将能够在本地InfinBand带宽或附近执行/latencyWildfire将为资源分配、调度和用户支持提供新颖的方法，为高吞吐量计算提供更快响应的队列，中期存储分配，具有定制软件堆栈的虚拟化环境，物理/虚拟机的专用分配，支持科学网关和高速网络上的带宽预留。Wildfire的设计目的是有效地服务98%的需要少于1000个内核的XSEDE作业，同时也支持更大的作业。该奖项利用并增强了通过XSEDE项目提供的服务。收购Wildfire将有助于增加研究人员的多样性，使其能够有效地利用先进的计算资源，并通过虚拟化、科学网关和专注于本科生、研究生和研究生水平的教育活动，建立潜在用户的管道。

The University of California at San Diego will provide a ground-breaking new computing facility, Wildfire, that will be made available to the research community to both well established users of high end computing (HEC) and especially to new user communities that are less familiar with how HEC can advance their scientific and engineering goals. The distinguishing features of Wildfire are:(i) Deliver 1.8-2.0 Petaflop/s of long sought capacity for the 98% of XSEDE jobs (50% of XSEDE core hours) that use fewer than 1,000 cores and also support larger jobs. The exact number will depend on the speed of the processor being delivered by Intel but cannot be less that 1.8 Petaflop/s.(ii) Provide 7 PB of Lustre-based Performance Storage at 200 GB/s bandwidth for both scratch and allocated storage as well as 6 PB of Durable Storage(iii) Ensure high throughput and responsiveness using allocation/scheduling using proven policies on earlier deployed systems such as Trestles and Gordon(iv) Establish a rapid-access queue to provide new accounts within one day of the request(v) Enable community-supported custom software stacks via virtualization for communities that are unfamiliar with HPC environments. These virtual clusters will be able to perform at or near native InfinBand bandwidth/latencyWildfire will provide novel approaches for resource allocation, scheduling, and user support, queues with quicker response for high-throughput computing, medium-term storage allocations, virtualized environments with customized software stack, dedicated allocations of physical/virtual machines, support for Science Gateways and bandwidth reservations on high-speed networks. Wildfire has been designed to efficiently serve the 98% of XSEDE jobs that need fewer than 1,000 cores, while also supporting larger jobs. The award leverages but also enhances the services available through the XSEDE project. The Wildfire acquisition will work to increase the diversity of researchers able to effectively make use of advanced computational resources and establish a pipeline of potential users through virtualization, science gateways and educational activities focused on the undergraduate, graduate and post-graduate levels.
