Category I: Jetstream 2: Accelerating Science and Engineering On-Demand

在可供分析的数据的可用性以及研究人员使用的分析工具的广度和多样性方面，科学的前沿正在迅速发展。为了有效地分析和理解这种不断增长的信息缓存，并使利用新的人工智能工具进行研究成为可能，研究人员需要通过云交付按需、交互式和程序化的网络基础设施（CI）。Jetstream 2是一个易于扩展和重新配置的系统，能够支持多种按需访问和使用模式。该系统还将通过虚拟GPU功能实现“AI for Everyone”，并通过印第安纳大学领导的五个合作伙伴进行广泛推广，从而彻底改变国家网络基础设施（CI）生态系统。该项目承诺使研究界能够使用更多样化的计算资源，并将其覆盖范围扩大到学生群体，从广泛的学科中汲取，从而为建设未来的STEM劳动力做出贡献。Jetstream 2将是一个8 PetaFLOPS （PFLOPS）的云计算系统，使用下一代AMD“Milan”cpu和最新的NVIDIA Tensor Core gpu，存储容量为18.5 PB。由5个计算系统组成，Jetstream 2的主要系统将位于印第安纳大学，其余4个区域系统将部署在亚利桑那州立大学（ASU）、康奈尔大学、夏威夷大学（UH）和德克萨斯高级计算中心（TACC）。与亚利桑那大学、约翰霍普金斯大学和大学大气研究公司（UCAR）的其他合作伙伴关系将有助于Jetstream 2无与伦比的可用性，并为广泛的科学工作提供支持。Jetstream团队一直处于培训研究社区从批处理计算方法过渡到采用云风格使用的最前沿。Jetstream 2将继续这条道路，并将简化学术和商业云计算之间的过渡。一些高级特性包括按键式虚拟集群、高级高可用性科学网关服务（包括商业云集成）、用于JupyterHubs的联合身份验证、通过可编程CI在同一系统内实现裸机和虚拟化、除按需计算外还支持按需数据密集型工作负载、高性能软件定义存储和高级多平台编排功能。喷射流2号将产生深远的社会效益。作为增强的教育基础设施，它将为更多的学生提供服务，从传统的本科生到希望获得计算技术培训的领域科学专家，而不是任何其他nsf资助的CI资源。这些学生将更好地充分参与到不断发展的STEM劳动力中。除了支持跨多个学科的新研究、发现和创新外，Jetstream 2还将推进国家CI生态系统，并扩大现有NSF投资的更广泛影响。Jetstream 2的“核心服务”将展示一个实用的分布式云计算模型，这将激励学术机构将自己的资金投入到新的高级CI设施中。虽然规模不大，但这些设施将代表可重构计算的最新水平。Jetstream 2的实施还将证明，高校可以将自己的资金持续投入到高效、灵活的CI资源中，从而产生可观的投资回报。总之，Jetstream 2将改变国家CI景观，使国家受益匪浅。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The frontiers of science are rapidly evolving in regard to availability of data to be analyzed and the breadth and variety of analytical tools that researchers use. To effectively analyze and make sense of this ever-growing cache of information, and to make it possible to leverage new artificial intelligence tools for research, researchers need on-demand, interactive, and programmatic cyberinfrastructure (CI) delivered via the cloud. Jetstream 2 is a system that will be easy to expand and reconfigure, and capable of supporting diverse modes of on-demand access and use, The system will also revolutionize the national cyberinfrastructure (CI) ecosystem by enabling “AI for Everyone” with virtual GPU capabilities and widespread outreach through the five partners, led by Indiana University. The project promises to enable the research community to use a greater variety of computational resources and to expand its reach into student populations, drawn from a broad range of disciplines, thus contributing to building the future STEM workforce.Jetstream 2 will be an 8 PetaFLOPS (PFLOPS) cloud computing system using next-generation AMD “Milan” CPUs and the latest NVIDIA Tensor Core GPUs with 18.5 petabytes (PB) of storage. Consisting of five computational systems, Jetstream 2’s primary system will be located at Indiana University, with four modest regional systems deployed nationwide at Arizona State University (ASU), Cornell University, the University of Hawaiʻi (UH), and the Texas Advanced Computing Center (TACC). Additional partnerships with the University of Arizona, Johns Hopkins University, and University Corporation for Atmospheric Research (UCAR) will contribute to Jetstream 2’s unparalleled usability and support for a broad range of scientific efforts.The Jetstream team has been at the forefront of training the research community to transition from batch computing methods to adopt cloud-style usage. Jetstream 2 will continue this path and will ease the transition between academic and commercial cloud computing. Some of the advanced features include push-button virtual clusters, advanced high-availability science gateways services (including commercial cloud integration), federated authentication for JupyterHubs, bare metal and virtualization within the same system through programmable CI, support for on-demand data intensive workloads in addition to on-demand computation, high-performance software-defined storage, and advanced multi-platform orchestration capabilities.Jetstream 2 will have far-reaching societal benefits. As enhanced educational infrastructure, it will serve more students, from traditional undergraduates to domain-science experts desiring training in computational techniques, than any other NSF-funded CI resource. These students will be better equipped to fully participate in the evolving STEM workforce. In addition to enabling new research, discovery, and innovation across many disciplines, Jetstream 2 will advance the national CI ecosystem and extend the broader impacts of existing NSF investments. Jetstream 2’s “Core Services” will demonstrate a practical model of distributed cloud computing that will give academic institutions an incentive to invest their own funds in new advanced CI facilities. Although modest in scale, these facilities will represent the state of the art in reconfigurable computing. The implementation of Jetstream 2 will also demonstrate that colleges and universities can invest sustainable amounts of their own funds in highly-effective, flexible CI resources that generate a significant return on investment. In sum, Jetstream 2 will transform the national CI landscape and greatly benefit the nation.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.
