    Using the Jetstream Research Cloud to provide Science Gateway resources
    (2017-05) Knepper, Richard; Coulter, Eric; Pierce, Marlon; Marru, Suresh; Pamidighantam, Sudhakar
    We describe the use of the Jetstream research-cloud, a purpose-built system with the goal of supporting “long-tail” research by providing a flexible, on-demand research infrastructure, to provide scalable back-end resources for science gateways. In addition to providing cloud-like resources for on-demand science, Jetstream offers the capability to instantiate long-running clusters which support science gateways. Science gateways are web-based systems built on computational infrastructure which provide commonly-used tools to a community of users. We created a persistent cluster on the Jetstream system which is connected to the SEAGrid science gateway and provides additional compute resources for a variety of quantum chemistry calculations. We discuss the further application of toolkits provided by the Extreme Science and Engineering Discovery Environment (XSEDE) to build general-purpose clusters on the research cloud.

    Jetstream – performance, early experiences, and early results
    (2016-07-17) Stewart, Craig A.; Hancock, David Y.; Vaughn, Matthew; Fischer, Jeremy; Cockerill, Tim; Liming, Lee; Merchant, Nirav; Miller, Therese; Lowe, John Michael; Stanzione, Daniel C.; Taylor, James; Skidmore, Edwin
    Jetstream is a first-of-a-kind system for the NSF - a distributed production cloud resource. The NSF awarded funds to create Jetstream in November 2014. Here we review the purpose for creating Jetstream, present the acceptance test results that define Jetstream’s key characteristics, describe our experiences in standing up an OpenStack-based cloud environment, and share some of the early scientific results that have been obtained by researchers and students using this system. Jetstream offers unique capability within the XSEDE-supported US national cyberinfrastructure, delivering interactive virtual machines (VMs) via the Atmosphere interface developed by the University of Arizona. As a multi-region deployment that operates as a single integrated system, Jetstream is proving effective in supporting modes and disciplines of research traditionally underrepresented on larger XSEDE-supported clusters and supercomputers. Already, researchers in biology, network science, economics, earth science, and computer science have used Jetstream to perform research – much of it research in the “long tail of science.”

    Jetstream: A Distributed Cloud Infrastructure for Under-resourced Higher Education Communities
    (2015-06-16) Fischer, Jeremy; Tuecke, Steven; Foster, Ian; Stewart, Craig A.
    The US National Science Foundation (NSF) in 2015 awarded funding for a first-of-a-kind distributed cyberinfrastructure (DCI) system called Jetstream. Jetstream will be the NSF’s first production cloud for general-purpose science and engineering research and education. Jetstream, scheduled for production in January 2016, will be based on the OpenStack cloud environment software with a menu-driven interface to make it easy for users to select a pre-composed Virtual Machine (VM) to perform a particular discipline-specific analysis. Jetstream will use the Atmosphere user interface developed as part of iPlant, providing a low barrier to use by practicing scientists, engineers, educators, and students, and Globus services from the University of Chicago for seamless integration into the national cyberinfrastructure fabric. The team implementing Jetstream has as their primary mission extending the reach of the NSF’s eXtreme Digital (XD) program to researchers, educators, and research students who have not previously used NSF XD program resources, including those in communities and at institutions that traditionally lack significant cyberinfrastructure resources. We will, for example, use virtual Linux Desktops to deliver DCI capabilities supporting research and research education at small colleges and universities, including Historically Black Colleges and Universities (HBCUs), Minority Serving Institutions (MSIs), Tribal colleges, and higher education institutions in states designated by the NSF as eligible for funding via the Experimental Program to Stimulate Competitive Research (EPSCoR). Jetstream will be a novel distributed cyberinfrastructure, with production components in Indiana and Texas. In particular, Jetstream will deliver virtual Linux desktops to tablet devices and PDAs with reasonable responsiveness running over cellular networks. This paper will discuss design and application plans for Jetstream as a novel Distributed CyberInfrastructure system for research education.
