IU tech experts, faculty, students share insights at national conference

Papers, posters, tutorials and visualizations: IU experts shine at Extreme Science and Engineering Discovery Environment (XSEDE) Conference

BLOOMINGTON, Ind. — Indiana University research technology experts have a strong showing at this week's 2014 Extreme Science and Engineering Discovery Environment (XSEDE) Conference, taking place July 13-18 in Atlanta.

Staff from the Research Technologies (RT) division of University Information Technology Services (UITS) and students and faculty from the IU School of Informatics and Computing (SOIC) will present papers and posters and lead tutorials and workshops at the annual event. RT and SOIC are both affiliated with the IU Pervasive Technology Institute, a collaborative research and development organization at IU that is a patron sponsor of XSEDE14.

"IU’s overall presence at the XSEDE14 conference represents the excellent work of the Pervasive Technology Institute, School of Informatics and Computing, and University Information Technology Services. From advanced distributed workflows to national outreach, IU is a leader in cyberinfrastructure and informatics," said Craig Stewart, executive director of the Pervasive Technology Institute and SOIC adjunct associate professor. Stewart and his staff have a strong association with XSEDE. In 2012, Stewart organized the inaugural XSEDE conference and served as general chair.

XSEDE is a National Science Foundation-supported project that brings together supercomputers, data collections, and computational tools and services to support science and engineering research and education. IU is a key partner in XSEDE, and the university's Mason and Quarry computer clusters are XSEDE resources regularly used by researchers around the world.

IU-led events and presentations at the conference will include:


  • "Methods For Creating XSEDE Compatible Clusters," presented by Jeremy Fischer, Richard Knepper, Matthew Standish, Craig Stewart, Resa Alvord, David Lifka, Barbara Hallock and Victor Hazelwood.
  • "XSEDE Campus Bridging Pilot Case Study," presented by Rich Knepper.
  • "Accelerating Sparse Canonical Correlation Analysis for Large Brain Imaging Genetics Data," presented by Guangchen Ruan.
  • "TextRWeb: Large-Scale Text Analytics with R on the Web," presented by doctoral student Guangchen Ruan, with Hui Zhang, Eric Wernert and Beth Plale.


  • "Campus Bridging Technologies – using the Basic XSEDE Cluster Stack," presented by Rich Knepper.
  • "Science Gateway Platform (SciGaP) Tutorial: Developing Science Gateways using Apache Airavata," presented by Marlon Pierce.

Visualization showcase

  • "Visual Computing of Large Dental Imaging Data for Investigative Caries Studies," presented by Guangchen Ruan.

Birds of a Feather (BOF) talk

  • "Empowering Campus Champions and Campus Bridging Engineers," presented by Robert Henschel, Rich Knepper, Scott Michael and Abhinav Thota.


  • "On Comparison of R Performance with Hardware-Enabled Parallelism," presented by Guangchen Ruan.

The annual XSEDE conference showcases the discoveries, innovations, and achievements of those who use, build, and support XSEDE resources and services, as well as those involved in related digital resources endeavors around the world. The event attracts hundreds of researchers, technology experts, educators, and students from across the United States. For complete information, including the conference schedule, see
