Item UCS Times: Big improvements in statistical software support(Indiana University, 1991-09) Stewart, Craig A.Historical record of UCS Times article about the Stat/Math Center and software it supported in 1991.Item UCS Times: More math software; better support / Software news(Indiana University, 1991-11) Stewart, Craig A.Historical UCS Times article about the Stat/Math Center and software it supported in 1991Item Establishing an Information Architecture Integration with an Open Systems Environment(EDUCAUSE, 1992-01-01) Bernbom, Gerry; Cromwell, DennisThis paper describes the conceptual basis for a structured data architecture, and its integration with the deployment of open systems technology. The key strategic initiatives which brought these efforts together are discussed: commitment to improved data access, migration to relational database technology, deployment of a high-speed, multi-protocol network, and orientation to workstation-centered computing. Details of Indiana University's data architecture are presented, focusing on the relationship of operational to information-detail databases, the creation of synthetic data structures and higher order "data collections," and the integration of the university-wide architecture with local and departmental data sources. Discussion of the underlying technology paradigm addresses the integration of proprietary components with "open" systems solutions in a strategy of technology coexistence that addresses: mainframe/server, workstation/client, networks, gateways, and database management systems. Finally, some next critical events are outlined for both the architected data environment and the open systems technology environment.Item UCS Times: Statistical and mathematical computing at IU: A look back; a look forward(Indiana University, 1992-11) Stewart, Craig A.Historical UCS Times article giving a brief overview of statistical and mathematical computing at IU through the early 1990sItem Security in a Client-Server Environment(1993-12-09) Bernbom, Gerry; Bruhn, Mark; Cromwell, DennisThis paper describes the strategy adopted by Indiana University in the design and implementation of a security model for the client/server environment. The strategic initiatives which were the catalyst for this effort are presented: deployment of a high speed network, an orientation to workstation-centered computing, and a growing commitment to open-systems solutions. Details of the IU security architecture are discussed, focusing on the three components of security -- identification, authentication and authorization -- and why they are critical success factors to implementing a client/server information system. The paper identifies security problems of an open-systems and client-server environment, the technology components of a security solution, and the work done by Indiana University to supplement the immature technology in this area. The paper also makes a case for clear analysis of security exposures, and the importance evaluation security solutions in light of evolving industry standards.Item Distributed Image Management (DIM) for Cluster Administration(IBM, Inc. and Indiana University, 1996-11) Morjan, Peter; Rodgers, Greg; Aiken, Ross; Turner, George; Hancock, Dave; Feinswog, LaurieDistributed Image Management (DIM) is a centralized cluster management tool developed by Peter Morjan at IBM for large scale computing systems. This report discusses the technology behind DIM and its features and benefits.Item A Methodology for Evaluation Recordkeeping Systems(1997-03-27) Bernbom, GerryIn June, 1995, IU began a two year project to establish archival requirements for IU's electronic records in the target areas of Financial Management Services and Student Services. As part of that project a methodology has been developed to evaluate information systems against the University of Pittsburgh Functional Requirements for Evidence in Recordkeeping in the context of business transactions.Item Acquisition of a Distributed Computation and Immersive Visualization Environment for Complex Systems - Scientific Applications on Arrays of Multiprocessors (SCAAMP)(The Trustees of Indiana University, 1998-09) Bramley, Randall; McMullen, Donald F.; Cohn, Haldan; Davidson, Ernest; Durisen, Richard H.; Gannon, Dennis; Girvin, Steve; Gottlieb, Steve; Jolly, Michael S.; Lugger, Phyllis; MacDonald, Allan; Martyna, Glenn; Otroleva, Peter; Pierce, Michael J.; Shakespeare, RobItem Indiana University Shared University Research grants - Report on Accomplishments(2000-06-20) Stewart, Craig A.; Bramley, Randall; Bernbom, Gerry; Dunn, Jon W.; Meglicki, Zdzislaw; McMullen, D.F.; Hart, David; Papakhian, MaryIndiana University has a decades-old research relationship with IBM. This relationship has expanded and deepened significantly in the past two years, in large part thanks to the SUR grants awarded by IBM to IU, totaling $2.45M (retail value) in IBM high performance hardware.Item Research and Academic Computing Implementation Plan(2000-07) Peebles, Christopher S.; Stewart, Craig A.; Bernbom, Gerry; McMullen, Donald F.; Shankar, Anurag; Samuel, John; Daniels, John; Papakhian, Mary; Hart, David; Walsh, John; Wernert, EricItem INGEN's advanced IT facilities: The least you need to know(2002) Cruise, Robert; Hart, David; Papakhian, Mary; Repasky, Richard; Samuel, John; Shankar, Anurag; Stewart, Craig A.; Wernert, EricItem I-Light Applications Workshop 2002 Proceedings(2002-12-04) I-LightIndiana Governor Frank O'Bannon symbolically lit the fiber of the I-Light network on December 11, 2001. I-Light is a unique, high-speed fiber optic network connecting Indiana University Bloomington, Indiana University–Purdue University Indianapolis, and Purdue University West Lafayette with each other and with Abilene, the national high-speed Internet2 research and education network. This unique university-owned high speed network connects three of the Indiana's great research campuses. One year after the lighting of the network, we invited researchers from Indiana University and Purdue University to come together to discuss some of the research and instructional achievements that have been made possible in just one short year of the existence of I-Light. The results were dramatic: on December 4, 2002, more than 150 researchers gathered together in Indianapolis to discuss research and instructional breakthroughs made possible by I-Light.Item Technical Report: Distributed Parallel Computing Using Windows Desktop Systems(2003) Hart, David; Grover, Douglas; Liggett, Matt; Repasky, Richard; Shields, Corey; Simms, Stephen; Sweeny, Adam; Wang, PengLike many large institutions, Indiana University has thousands of desktop computers devoted primarily to running office productivity applications on the Windows operating system, tasks which are necessary but that do not use the computers’ full capacity. This is a resource worth pursuing. However, the individual desktop systems do not offer enough processing power for a long enough period of time to complete large scientific computing applications. Some form of distributed, parallel programming is required, to make them worth the chase. They must be instantly available to their primary users, so they are available only intermittently. This has been a serious stumbling block: currently available communications libraries for distributed computing do not support such a dynamic communications world well. This paper introduces Simple Message Broker Library (SMBL), which provides the flexibility needed to take advantage of such ephemeral resources.Item 2003 Report on Indiana University Accomplishments supported by Shared University Research Grants from IBM, Inc.(2003) Stewart, Craig A.; Papakhian, Mary; Hart, David; Shankar, Anurag; Arenson, Andrew; McMullen, D.F; Palakal, Mathew; Dalkilic, Mehmet; Ortoleva, PeterIndiana University and IBM, Inc. have a very strong history of collaborative research, aided significantly by Shared University Research (SUR) grants from IBM to Indiana University. The purpose of this document is to review progress against recent SUR grants to Indiana University. These grants focus on the joint interests of IBM, Inc. and Indiana University in the areas of deep computing, grid computing, and especially computing for the life sciences. SUR funding and significant funding from other sources, including a $1.8M grant from the NSF and a portion of a $105M grant to Indiana University to create the Indiana Genomics Initiative, have enabled Indiana University to achieve a suite of accomplishments that exceed the ambitious goals set out in these recent SUR grants.Item Opportunities for Biomedical Research and the NIH through High Performance Computing and Data Management(2003-01-10) Coalition for Academic Scientific ComputationThe biomedical sciences are advancing at a tremendous rate. Some of the most notable recent accomplishments (such as the assembly of the human genome) have depended upon the use of high performance computing and data management (HPC). There are important areas of opportunity for the biomedical sciences to accelerate advances in knowledge and in practical medical treatments through the use of high performance computing. As we enter into the “century of biology” there are critical challenges in the areas of data organization, management, and analysis; simulation; and translational biomedical research. These challenges can be met only through investment in training, tools, and infrastructure that will enable greater use of high performance computing in biomedical research.Item University Information Technology Services' Advanced IT Facilities: The least every researcher needs to know(2003-02) Cruise, Robert; Hart, David; Papakhian, Mary; Repasky, Richard; Samuel, John; Shankar, Anurag; Stewart, Craig A.; Wernert, EricThis document is designed to be read as a printed document, and designed to permit anyone at all familiar with computers and the Internet to start at the beginning, get a general overview of UITS' advanced IT facilities and what they offer, and then read the detailed portions of the document that are of interest. In many cases, examples are provided, as well as directions on how to download sample files. And in some cases there is information that one is best off really not learning – for example the process of logging into IU's IBM supercomputer the first time involves setup steps that should be followed, keystroke by keystroke, from the directions presented herein, and then promptly forgotten. This document is intended to be a starting point, not a comprehensive guide. As such it should get any reader off to a good start, but then point the reader in the direction of consulting staff and online resources that will permit the reader to get additional help and information as needed. Most of all, this document is provided for the convenience of researchers, who may peruse this information at their leisure. Our hope and expectation is that consultants in UITS will provide extensive help and programming assistance to IU researchers who wish to make use of these excellent IT facilities.Item Creation of the AVIDD Data Facility: A Distributed Facility for Managing, Analyizing and Visualizing Instrument-Driven Data (AVIDD)(The Trustees of Indiana University, 2003-09) Huffaman, John C.; Bramley, Randall; McRobbie, Michael; Stewart, CraigItem IU-IBM DiscoveryLink Project Final Report(2003-10-28) Stewart, Craig A.This highly fruitful collaborative effort between IU and IBM life sciences/DB2 teams has resulted in the institution at IU of a Centralized Life Science Data (CLSD) service. CLSD provides to IU researchers a unified, SQL interface to diverse, public life sciences data.Item IU-IBM Protein Family Annotator Project Final Report(2004-02-10) Stewart, CraigIn June 2002, IU and IBM signed a joint study agreement (W0125820) to develop protein family annotator software as part of a larger IU-IBM life sciences partnership. IBM provided $35,000 for the project. Matching funds were provided by IU's Indiana Genomics (INGEN) project and School of Informatics to procure hardware (two IBM Intel servers) and to be applied toward a programmer's salary. This document serves as the final report on the joint study agreement.
