Science and engineering rely upon an increasingly complex and integrated ecosystem of advanced computing and data systems, scientific software, and expertise to conduct research that leads to new knowledge and discovery, and improves the Nation's competitiveness and the health and welfare of its citizens. From the building blocks of life on earth to the deepest mysteries of the universe, researchers use this cyberinfrastructure (CI) to carry out computation and analysis at ever larger scales and complexity. Computing without Boundaries: Cyberinfrastructure for the Long Tail of Science is a transformational project from the San Diego Supercomputer Center at the University of California, San Diego, designed to address these challenges. The centerpiece of the project is the acquisition, deployment, and operation of Expanse, a powerful supercomputer that will complement and extend NSF's Innovative High-Performance Computing (HPC) program. Expanse will: 1) increase the capacity and performance for thousands of users of batch-oriented and science gateway computing; and 2) provide new capabilities that will enable research increasingly dependent upon heterogeneous and distributed resources composed into integrated and highly usable CI. Expanse will feature innovations in system software, operations, and support that extend its capabilities far beyond the limits of the physical system. Through its integration with the public cloud and the Open Science Grid, collaboration with the Science Gateway Community Institute, and support for composable systems, Expanse will become part of a more inclusive national CI. The long tail of computing reflects diversity in science, researchers, their institutions, and those who support and operate CI. The project will reach out to underserved and under-resourced communities, through new initiatives like HPC@MSI, which will allocate a portion of Expanse to Minority Serving Institutes via a rapid access allocation to help them quickly use this powerful new resource. Projected to have a peak speed of 5 Petaflop/s, Expanse will feature next-generation Intel Central Processing Units (CPUs), NVIDIA Graphics Processing Units (GPUs), and a Mellanox InfiniBand network. It will be composed of 13 SDSC Scalable Compute Units (SSCUs), each of which contains 56 CPU nodes and 4 GPU nodes along with over 60 TB of distributed non-volatile memory storage for user scratch. The SSCUs will be integrated with a 12-PB Lustre parallel file system and 7 PB of object storage. SDSC, along with its partners Dell and Aeon Computing, will deploy Expanse in SDSC's energy-efficient data center on the UCSD campus. Expanse will be connected to multiple high-performance research and education networks at 100 Gbps and reach thousands of users who require high performance, but modest-scale resources. Allocation and usage policies will be tailored to achieve fast turnaround and responsiveness. Experts in computational science, data-intensive computing, scientific workflows, and large-scale systems operations will support Expanse at the highest levels of utilization, reliability, and usability. Through integration with national CI, Expanse will enable new models of computing and research that require the full complement of HPC systems and simulation, experimental data analysis, and computational expertise to support and facilitate breakthrough science. Knowledge gained through the project will lead to improvements in algorithms, software, and systems management tools, as well as a better understanding of how integrated CI can be configured to support emerging research.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

科学和工程依靠高级计算和数据系统，科学软件和专业知识的日益复杂和综合的生态系统来进行研究，从而导致新知识和发现，并提高国家的竞争力以及其公民的健康和福利。从地球上的生命基础到宇宙的最深层奥秘，研究人员使用这种网络基础设施（CI）来以更大的规模和复杂性进行计算和分析。无边界的计算：科学长尾的网络基础设施是来自圣地亚哥分校圣地亚哥超级计算机中心的转型项目，旨在应对这些挑战。该项目的核心是Expanse的收购，部署和操作，Expanse是一个强大的超级计算机，将补充和扩展NSF的创新高性能计算（HPC）程序。 Expanse将：1）增加成千上万的面向批处理和科学网关计算的用户的能力和性能； 2）提供新的功能，使研究能够越来越依赖于综合且高度可用的CI组成的异质和分布式资源。 Expanse将在系统软件，操作和支持中以远远超出物理系统限制的功能为特色。通过与公共云和开放科学网格的集成，与科学网关社区研究所的合作以及对可组合系统的支持，Expanse将成为更具包容性的国家CI的一部分。计算的长尾巴反映了科学，研究人员，其机构以及支持和运营CI的多样性。该项目将通过HPC@MSI等新举措来接触到服务不足和资源不足的社区，该计划将通过快速的访问分配分配给少数民族服务机构，以帮助他们快速使用这一强大的新资源。 Expanse预计将具有5 PETAFLOP/S的峰值速度，将具有下一代Intel Central Processing单元（CPU），NVIDIA图形处理单元（GPU）和Mellanox Infiniband网络。它将由13个SDSC可伸缩计算单元（SSCU）组成，每个计算单元包含56个CPU节点和4个GPU节点，以及超过60 TB的分布式非挥发存储器存储存储，用于用户刮擦。 SSCUS将与12-PB光泽并行文件系统和7 pb对象存储集成。 SDSC及其合作伙伴Dell和Aeon Computing将在UCSD校园的SDSC节能数据中心部署。 Expanse将与100 Gbps的多个高性能研究和教育网络连接，并吸引成千上万需要高性能但适度资源的用户。分配和使用政策将被量身定制，以实现快速的周转和响应能力。计算科学，数据密集型计算，科学工作流和大规模系统操作的专家将支持最高利用率，可靠性和可用性的扩展。通过与国家CI的集成，Expanse将启用新的计算和研究模型，以完全补充HPC系统以及模拟，实验数据分析以及计算专业知识，以支持和促进突破科学。通过该项目获得的知识将导致算法，软件和系统管理工具的改进，以及对如何配置集成CI的配置更好地理解以支持新兴研究。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的审查审查的审查标准来通过评估来通过评估来支持的。
