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——一个自提供的、可扩展的科学和工程云环境。Jetstream将是一种新型的计算研究资源，面向国家（非机密）研究社区开放——一种数据分析和计算资源，美国科学家和工程师将随时随地交互式地使用它来进行研究。Jetstream将补充目前NSF资助的计算资源，并为NSF计算资源带来一个基于云的系统，该系统将商业云计算资源的最佳元素与现有的一些最佳软件结合起来，用于解决重要的科学问题。这个系统将使许多美国研究人员和工程师能够做出新的发现，这些发现对了解我们周围的世界很重要，并将帮助研究人员做出新的发现，提高美国公民的生活质量。在技术细节方面，Jetstream将是一个可配置的大规模计算资源，它利用按需和持久虚拟机技术来支持比当前NSF资源所能容纳的更广泛的软件环境和服务。作为一种完全可配置的“云”资源，Jetstream弥补了当前生态系统中明显的主要缺口，该生态系统拥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。作为科学领域的开放云，Jetstream将：*提供“自助”学术云服务，使研究人员或学生能够从已发布的图书馆中选择虚拟机映像，或者创建或定制他们自己的虚拟环境，用于特定学科或任务的个性化研究计算。*托管持久性虚拟机，为科学网关和其他科学服务提供命令行接口以外的服务。例如，Jetstream将成为流行的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用户带入NSF生态系统。*启用共享计算、数据和再现性的新模式。*通过向资源有限的机构提供虚拟桌面服务，扩展对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
