Gateways to Discovery: Cyberinfrastructure for the Long Tail of Science

位于圣地亚哥的加州大学将提供一个突破性的新计算设施Wildfire，该设施将提供给研究社区，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（XSEDE核心小时数的50%）提供1.8-2.0 Petaflop/s的长期追求容量，这些作业使用不到1，000个核心，并且还支持更大的作业。 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 Petaflop/s。(ii)提供7 PB基于Lustre的性能存储，带宽为200 GB/s，用于临时存储和分配存储，以及6 PB持久存储（iii）使用Trestles和Gordon等早期部署系统上经过验证的策略，使用分配/调度确保高吞吐量和响应能力（iv）建立快速访问队列，以便在请求后一天内提供新帐户（v）启用社区-通过虚拟化为不熟悉HPC环境的社区提供支持的自定义软件堆栈。 这些虚拟集群将能够在原生InfinBand带宽/延迟或接近原生InfinBand带宽/延迟的情况下运行Wildfire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，对科学网关的支持以及高速网络上的带宽预留。 Wildfire旨在高效地为98%的XSEDE作业提供服务，这些作业需要不到1，000个核心，同时还支持更大的作业。该奖项利用但也增强了通过XSEDE项目提供的服务。收购Wildfire将致力于增加研究人员的多样性，从而能够有效地利用先进的计算资源，并通过虚拟化，科学网关和教育活动建立潜在用户的管道，重点是本科生，研究生和研究生水平。

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.
