Scott; Rodgers, Greg; Turner, George; Hancock, David Y.; Wang, Peng; Saied, Faisal; Pierce, Marlon; Aiken, Ross; Mueller, Matthias S.; Jurenz, Matthias; Lieber, Matthias; Tillotson, Jenett; Plale, Beth A.The purpose of this report is to present the results of benchmark tests with Big Red, an IBM e1350 BladeCenter Cluster. This report is particularly focused on providing details of system architecture and test run results in detail to allow for analysis in other reports and comparison with other systems, rather than presenting such analysis here.Item Big Data on Ice: The Forward Observer System for In-flight Synthetic Aperture Radar Processing(2015) Knepper, Richard; Link, Matthew R.; Standish, MatthewWe introduce the Forward Observer system, which is designed to provide data assurance in field data acquisition while receiving significant amounts (several terabytes per flight) of Synthetic Aperture Radar data during flights over the polar regions, which provide unique requirements for developing data collection and processing systems. Under polar conditions in the field and given the difficulty and expense of collecting data, data retention is absolutely critical. Our system provides a storage and analysis cluster with software that connects to field instruments via standard protocols, replicates data to multiple stores automatically as soon as it is written, and provides pre-processing of data so that initial visualizations are available immediately after collection, where they can provide feedback to researchers in the aircraft during the flight.Item Big Red II & Supporting Infrastructure(2013-04-09) Stewart, Craig A.; Link, Matthew R.; Hancock, David Y.Item Cyberinfrastructure, Cloud Computing, Science Gateways, Visualization, and Cyberinfrastructure Ease of Use(IGI Global, 2017-07-01) Stewart, Craig A.; Knepper, Richard; Link, Matthew R.; Pierce, Marlon; Wernert, Eric; Wilkins-Diehr, NancyComputers accelerate our ability to achieve scientific breakthroughs. As technology evolves and new research needs come to light, the role for cyberinfrastructure as “knowledge” infrastructure continues to expand. In essence, cyberinfra- structure can be thought of as the integration of supercomputers, data resources, visualization, and people that extends the impact and utility of information technology. This article defines and discusses cyberinfrastructure and the related topics of science gateways and campus bridging, identifies future challenges in cyberinfrastructure, and discusses challenges and opportunities related to the evolution of cyberinfrastructure and cloud computing.Item Cyberinfrastructure, Science Gateways, Campus Bridging, and Cloud Computing(IGI Global, 2014-07) Stewart, Craig A.; Knepper, Richard D.; Link, Matthew R.; Pierce, Marlon; Wernert, Eric A.; Wilkins-Diehr, NancyComputers accelerate our ability to achieve scientific breakthroughs. As technology evolves and new research needs come to light, the role for cyberinfrastructure as “knowledge” infrastructure continues to expand. This article defines and discusses cyberinfrastructure and the related topics of science gateways and campus bridging; identifies future challenges in cyberinfrastructure; and discusses challenges and opportunities related to the evolution of cyberinfrastructure, “big data” (datacentric, data-enabled, and data-intensive research and data analytics), and cloud computing.Item Gateway Hosting at Indiana University(2009-06) Lowe, John Michael; Shields, Corey; Hancock, David Y.; Link, Matthew R.; Stewart, Craig A.; Pierce, MarlonThe gateway hosting service at Indiana University provides science gateways and portals with hosting resources to facilitate the use of computation resources and storage within the TeraGrid. This service is designed with high availability in mind and is deployed across the Indianapolis and Bloomington campuses with redundant network, power, and storage. The service uses OpenVZ to give each gateway or portal its own virtual environment while making the most efficient use of the hardware and administrative resources. OpenVZ’s user beancounter quota system and fair-share scheduling for processes and I/O allows fair distribution of resource between virtual machines while allowing full utilization of the hardware. The ability to do live migration allows kernel updates without service interruption. Indiana University’s research network provides multiple low latency high bandwidth connections between campuses, other TeraGrid resource providers, and the Internet at large. The service is in use by a variety of projects such as FlyBase and TeraGrid Information Services and, since the service was put into production in August 2008, there have been 5.37 hours of down time.Item Indiana University Pervasive Technology Institute – Research Technologies: XSEDE Service Provider and XSEDE subcontract report (PY1: 1 July 2011 to 30 June 2012)(2012-10-03) Bolte, Jonathan; Wernert, Julie; Seiffert, Kurt; Simms, Stephen C.; Link, Matthew R.; Pierce, Marlon; Marru, Suresh; Hancock, David Y.; Miller, Therese; Stewart, Craig A.This document is a summary of the activities of the Research Technologies division of UITS, a Service & Cyberinfrastructure Center affiliated with the Indiana University Pervasive Technology Institute, as part of the eXtreme Science and Engineering Discovery Environment (XSEDE) during XSEDE Program Year 1 (1 July 2011 – 30 June 2012). This document consists of three parts: - Section 2 of this document describes IU’s activities as an XSEDE Service Provider, using the format prescribed by XSEDE for reporting such activities. - Section 3 of this document describes IU’s activities as part of XSEDE management, operations, and support activities funded under a subcontract from the National Center for Supercomputer Applications (NCSA), the lead organization for XSEDE.
