High Performance Computing System Acquisition: Jetstream - A Self-Provisioned, Scalable Science and Engineering Cloud Environment

高性能计算系统收购：Jetstream -一个自我配置的，可扩展的科学和工程云环境Jetstream将成为一种新型的计算研究资源，向国家（非机密）研究社区开放-美国科学家和工程师将随时随地交互使用的数据分析和计算资源进行研究。Jetstream将补充目前NSF资助的计算资源，并为NSF计算资源带来基于云的系统，将商业云计算资源的最佳元素与现有的一些最好的软件结合起来，以解决重要的科学问题。这一系统将使许多美国研究人员和工程师能够做出对了解我们周围世界至关重要的新发现，并将帮助研究人员做出改善美国公民生活质量的新发现，在技术细节方面Jetstream将是一个可配置的大规模计算资源，它利用了需求和持久的虚拟机技术，以支持更广泛的软件环境和服务比目前的NSF资源可以容纳。作为一个完全可配置的“云”资源，Jetstream弥补了当前生态系统中明显的主要差距，该生态系统具有针对大规模高性能计算、高内存、大数据、高吞吐量和可视化资源的机器。作为科学的开放云，Jetstream将：* 提供“自助式”学术云服务，使研究人员或学生能够从已发布的库中选择虚拟机映像，或者创建或定制自己的虚拟环境，用于特定学科或特定任务的个性化研究计算。*托管持久虚拟机，为科学网关和其他科学服务提供命令行界面以外的服务。例如，Jetstream将成为受欢迎的Galaxy科学工作台及其主要数据集的主要主机，从第一天起就将许多Galaxy用户带到NSF生态系统。* 启用共享计算、数据和再现性的新模式。* 通过使资源有限的机构可以访问虚拟桌面服务，扩大对NSF XSEDE生态系统的访问

High Performance Computing System Acquisition: Jetstream - a self-provisioned, scalable science and engineering cloud environmentJetstream will be a new type of computational research resource open for the national (nonclassified) research community - a data analysis and computational resource that US scientists and engineers will use interactively to conduct their research anytime, anywhere. Jetstream will complement current NSF-funded computational resources and bring a cloud-based system to the NSF computational resources incorporating the best elements of commercial cloud computing resources with some of the best software in existence for solving important scientific problems. This system will enable many US researchers and engineers to make new discoveries that are important to understanding the world around us and will help researchers make new discoveries that improve the quality of life of American citizens.In terms of technical details, Jetstream will be a configurable large-scale computing resource that leverages both on-demand and persistent virtual machine technology to support a much wider array of software environments and services than current NSF resources can accommodate. As a fully configurable "cloud" resource, Jetstream bridges the obvious major gap in the current ecosystem, which has machines targeted at large-scale High-Performance Computing, high memory, large data, high-throughput, and visualization resources. As the open cloud for science, Jetstream will: *Provide "self-serve" academic cloud services, enabling researchers or students to select a VM image from a published library, or alternatively to create or customize their own virtual environment for discipline- or task-specific personalized research computing.*Host persistent VMs to provide services beyond the command line interface for science gateways and other science services. For example, Jetstream will become a primary host of the popular Galaxy scientific workbench and its main datasets, bringing many Galaxy users to the NSF ecosystem from day one. *Enable new modes of sharing computations, data, and reproducibility. *Expand access to the NSF XSEDE ecosystem by making virtual desktop services accessible from institutions with limited resources
