This publication captures remarkable science and engineering accomplishments enabled by the HEC Program’s shared high-end computing systems and services. For several decades, high-end computing has played an important role in supporting NASA’s missions, with advancements as broad as preparing the Space Shuttle for Return to Flight, assimilating vast quantities of Earth observational data into climate models, and developing astrophysical calculations that help us better understand the origins of our universe. Today, our Program is committed to maintaining a stable, service- oriented computing environment for all four of the Agency’s mission directorates—Aeronautics Research, Exploration Systems, Science, and Space Operations—as well as NASA’s Engineering and Safety Center, external collaborators, and the nation. In this report, you will read about the technologies that help make NASA’s HEC Program successful. As described in the Program Overview, our user community encompasses more than 1,000 researchers from NASA field centers, government laboratories, academia, and industry across the United States. In partner- ship with them to achieve mission impact, we provide premier computing systems, high-speed networks, a huge data storage capacity, extensive programming and visualization expertise, and responsive user and training services. This increasingly integrated computing environment has fostered significant achievements within each mission directorate. In Science and Engineering Highlights, our principal investigators relate their successes. As NASA embarks on a new era of space exploration, scientific discovery, and aeronautics research, our HEC Program is committed to providing computing resources and services to help achieve NASA’s mission. With renewed emphasis on delivering a stable, service-driven computing environment that maximizes scien- tific discovery and engineering optimization, we will continue enabling NASA to turn today’s far-reaching dreams into tomorrow’s reality.

  • QUILT CIRCLE2020 a Letter from the President
    THE QUILT CIRCLE2020 A Letter From the President This 2020 Quilt Circle edition commemorates the 20th Anniversary of The Quilt. The fabric of our research and education (R&E) networking community has never been stronger. While our Quilt community has evolved in new and exciting ways in the past two decades, we have also been faced with a number of challenges which we take head-on and always with the spirit of collaboration. As we address the unprecedented challenges presented by the current global public health crisis due to the COVID-19 pandemic, the work of our members is more important than ever to the missions of their member communities. U.S. higher education institutions rely on R&E networks to give them a competitive edge in the most impactful scientific research initiatives which is essential in this crisis. We connect the educational institutions that support university medical centers and their associated hospitals. R&E networks also connect tens of thousands of other community anchor institutions, including K-12 schools, public libraries, local/state government, research sites, cultural institutions, public safety, and tribal lands. Being responsive and providing vital networking infrastructure and resources right now to address immediate needs is who we are and what we do. R&E networks are part of our nation’s critical infrastructure. This year’s edition of The Quilt Circle showcases several examples of the key role of R&E network members in both providing and facilitating the use-network infrastructure to further scientific discovery and collaborations at higher education institutions of all sizes.

Susan Hicks, Oak Ridge National Laboratory (ORNL) Vyto Grigaliunas, Network Analyst, Fermi National Accelerator Laboratory (FNAL) Abstract The importance of the Internet to modern High Energy Physics collaborators is clearly immense, and understanding how new developments in network technology impact net- works is critical to the future design of experiments. The next generation Internet Protocol (IPv6) is being deployed on testbeds and pro- duction networks throughout the world. The protocol has been designed to solve todays internet problems, and many of the features will be core Internet services in the future. In this talk the features of the protocol will be described. Details will be given on the deployment at sites important to High Energy Physics Research and the network services operating at these sites. In particular IPv6 deployment on the U.S. Energy Sciences Network (ESnet) will be reviewed. The connectivity and performance between High Energy Physics Laboratories, Universities and Institutes will be discussed. Keywords: Network, Technology, Internet, Protocol, IP, IPv6 1 Introduction High Energy and Nuclear Physics (HENP) experiments around the world generate huge amounts of data, much of which is transferred across networks to collaborators for analysis. Network technology has become critical to the success of experiments. The requirements of HENP researchers often means the networks they use become early implementors of new network technology.

  • Description of Omnipop for Proposals
    Description of OmniPoP for Proposals Summary The OmniPoP is a collaborative effort between 12 of the member universities of the Big Ten Academic Alliance. Together, these institutions have pooled their efforts to create a high performance shared infrastructure based in the Chicago area. This infrastructure was designed to complement and augment the shared fiber infrastructure that the Big Ten Academic Alliance members had previously purchased. The OmniPoP operates a high capacity switching infrastructure that supports 10 gigabit and 100 gigabit connections to its member institutions and equivalent high capacity links to national research and education networks such as Internet2, ESnet, and Starlight. This allows OmniPoP connections to be leveraged to provide services to large data flows in support of multi-institutional cooperative research efforts. Efforts supported today include interconnections between the Large Hadron Collider (LHC) Tier 2 efforts at the member institutions and the Midwest Openflow Crossroads Initiative (MOXI) project which links several midwest regional networks to the GENI backbone. OmniPoP Infrastructure and Peerings The Omnipop infrastructure consists of a redundant pair of 100 gigabit capable switches. These switches operate from geographically diverse co-location facilities within the Chicago metropolitan areas. These facilities also serve as Points of Presence (PoPs) for other major networks such as Internet2, ESnet (Department of Energy’s Energy Sciences Network), and Starlight (the international peering exchange), enabling seamless cross connections to the major national and international research and education networks that support much of the academic research community. An additional benefit to these facilities is that they offer the opportunity for Big Ten Academic Alliance members to co-locate additional network related equipment in support of their own projects independent of the OmniPoP core infrastructure.

  • Chapter 9: Enabling Capabilities for Science and Energy September 2015 9 Enabling Capabilities for Science and Energy
    QUADRENNIAL TECHNOLOGY REVIEW AN ASSESSMENT OF ENERGY TECHNOLOGIES AND RESEARCH OPPORTUNITIES Chapter 9: Enabling Capabilities for Science and Energy September 2015 9 Enabling Capabilities for Science and Energy Tools for Scientific Discovery and Technology Development Investment in basic science research is expanding our understanding of how structure leads to function—from the atomic- and nanoscale to the mesoscale and beyond—in natural systems, and is enabling a transformation from observation to control and design of new systems with properties tailored to meet the requirements of the next generation of energy technologies. At the core of this new paradigm is a suite of experimental and computational tools that enable researchers to probe and manipulate matter at unprecedented resolution. The planning and development of these tools is rooted in basic science, but they are critically important for technology development, enabling discoveries that can lead to broad implementation. These tools are available through a user facility model that provides merit-based open access for nonproprietary research. Each year, thousands of users leverage the capabilities and staff expertise for their research, while the facilities leverage user expertise toward maintenance, development, and application of the tools in support of the broader community of users. The challenges in energy science and technology development increasingly necessitate interdisciplinary collaboration. The multidisciplinary and multi-institutional research centers supported by DOE are designed to integrate basic science and applied research to accelerate development of new and transformative energy technologies. Capabilities supported by DOE and the DOE-Office of Science (SC) are enabling the following across science and technology: - The X-ray light and neutron sources provide unprecedented access to the structure and dynamics of materials and the molecular-scale basis of chemical reactions.
