Usage of UITS advanced research cyberinfrastructure for 2011

IU has a proud tradition in open access to its research computing and cyberinfrastructure (CI) facilities, going back to the precedents set by Marshall Wrubel (appointed the first permanent director of the IU Research Computing Center in 1955). Starting in 1997 President Myles Brand and then-Vice President Michael McRobbie initiated a tremendous acceleration in growth of IU’s cyberinfrastructure facilities through developing and then executing the first Indiana University Information Technology Strategic Plan. Through a decade and a half of purposeful execution of excellent strategies in support for research and scholarly activities generally, University Information Technology Services (UITS) has provided exceptional support to a group of researchers. This includes usage from disciplines that are among the traditional users of high performance computing – physics, chemistry, and astronomy, as well as emerging areas of application of HPC including biology, business, and the arts

Research Data Storage Available to Researchers Throughout the U.S. via the TeraGrid

This is a preprint of a paper in the Proceedings of the 34th annual ACM SIGUCCS fall conference (2006). Any opinions, findings, and conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of the National Science Foundation.Many faculty members at small to mid-size colleges and universities do important, high quality research that requires significant storage. In many cases, such storage requirements are difficult to meet with local resources; even when local resources suffice, data integrity is best ensured by maintenance of a remote copy. Via the nationally-funded TeraGrid, Indiana University offers researchers at colleges and universities throughout the US the opportunity to easily store up to 1 TB of data within the IU data storage system. The TeraGrid is the National Science Foundation's flagship effort to create a national research cyberinfrastructure, and one key goal of the TeraGrid is to provide facilities that improve the productivity of the US research community generally. Providing facilities that improve the capacity and reliability of research data storage is an important part of this. This paper will describe the process for storing data at IU via the TeraGrid, and will in general discuss how this capability is part of a larger TeraGrid-wide data storage strategy.U's involvement in the TeraGrid, and the presentation of this material, is based upon work supported by the National Science Foundation under Grants No. 0833618, SCI451237, SCI535258, and SCI504075. IU received a significant grant-in-kind as part of its initial deployment of the massive data storage system. The deployment of IU’s MDSS has also been supported by the Indiana Genomics Initiative and the Indiana METACyt Initiative, both supported through grants from the Lilly Endowment, Inc; by Shared University Research grants from IBM, Inc.; and by NSF grants 0116050 and 0521433

Usage of Indiana University computation and data cyberinfrastructure in FY 2011/2012 and assessment of future needs

This report details the past and current cyberinfrastructure resources that have been deployed by the Research Technologies (RT) division of University Information Technologies Services to support research and scholarly activities at IU. This report also presents data and detailed analysis of system usage and services supported by RT for the FY 2011/2012 period, projects future usage trends based on these data, and provides several recommendations for the most effective ways to meet the growing need for high performance computing resources in research and scholarly endeavors.This research was supported in part by: The Pervasive Technology Institute, Indiana Metabolomics and Cytomics Initiative, and the Indiana Genomics Initiative.

Gateway Hosting at Indiana University

In: Proceedings of the TeraGrid 2009 Conference, 22-25 June, Arlington, VA.The 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

Results of 2013 Survey of Parallel Computing Needs Focusing on NSF-funded Researchers

The field of supercomputing is experiencing a rapid change in system structure, programming models, and software environments in response to advances in application requirements and in underlying enabling technologies. Traditional parallel programming approaches have relied on static resource allocation and task scheduling through programming interfaces such as MPI and OpenMP. These methods are reaching their efficiency and scalability limits on the new emerging classes of systems, spurring the creation of innovative dynamic strategies and software tools, including advanced runtime system software and programming interfaces that use them. To accelerate adoption of these next-generation methods, Indiana University is investigating the creation of a single supported Reconfigurable Execution Framework Testbed (REFT) to be used by parallel application algorithm developers as well as researchers in advanced tools for parallel computing. These investigations are funded by the National Science Foundation Award Number 1205518 to Indiana University with Thomas Sterling as Principal Investigator, and Maciej Brodowicz, Matthew R. Link, Andrew Lumsdaine, and Craig Stewart as Co-Principal Investigators. As a starting point in this research we proposed to assess needs in parallel computing in general and needs for software tools and testbeds in particular within the NSF-funded research community. As one set of data toward understanding these needs, we conducted a survey of researchers funded by the National Science Foundation. Because of the strong possibility of distinct needs of researchers funded by what is now the Division of Advanced Cyberinfrastructure, researchers funded by the other divisions of the Computer and Information Sciences and Engineering Directorate, and researchers funded by the remainder of the NSF, we surveyed these populations separately. The report states the methods and summarize survey results.
