Using Traffic Shaping to Improve Performance for Raw Data Transfer and Video Streaming
Communication Networks and Services Research, Annual Conference on
By Andrei Hutanu, Sandeep Nimmagadda
Issue Date:May 2011
As networks and data transmission are becoming increasingly important for computational science, we are working on developing a visualization application that uses high-speed networks to aid scientists in their scientific exploration. However, we have iden...
An Experimental Distributed Visualization System for Petascale Computing
Computing in Science and Engineering
By Jinghua Ge, Andrei Hutanu, Cornelius Toole, Robert Kooima, Imtiaz Hossain, Gabrielle Allen
Issue Date:September 2010
<p>The coming era of petascale computing and heterogeneous platforms calls for fundamental changes in perspective on how we design distributed visualization software.</p>
Uncompressed HD video for collaborative teaching
International Conference on Collaborative Computing: Networking, Applications and Worksharing
By Andrei Hutanu, Ravi Paruchuri, Daniel Eiland, Milos Liska, Petr Holub, Steven R. Thorpe, Yufeng Xin
Issue Date:November 2007
This article describes a distributed classroom experiment carried out by five universities in the US and Europe at the beginning of 2007. This experiment was motivated by the emergence of new digital media technology supporting uncompressed high-definition...
Visualization of Time-Dependent Remote Adaptive Mesh Refinement Data
Visualization Conference, IEEE
By Ralf Kaehler, Steffen Prohaska, Andrei Hutanu, Hans-Christian Hege
Issue Date:October 2005
<p>Analysis of phenomena that simultaneously occur on different spatial and temporal scales requires adaptive, hierarchical schemes to reduce computational and storage demands. Adaptive Mesh Refinement (AMR) schemes support both refinement in space t...
Interactive Exploration of Large Remote Micro-CT Scans
Visualization Conference, IEEE
By Steffen Prohaska, Andrei Hutanu, Ralf Kähler, Hans-Christian Hege
Issue Date:October 2004
<p>Datasets of tens of gigabytes are becoming common in computational and experimental science. This development is driven by advances in imaging technology, producing detectors with growing resolutions, as well as availability of cheap processing po...
Network flow based resource brokering and optimization techniques for distributed data streaming over optical networks
Found in: Proceedings of the 15th ACM Mardi Gras conference: From lightweight mash-ups to lambda grids: Understanding the spectrum of distributed computing requirements, applications, tools, infrastructures, interoperability, and the incremental adoption of key capabilities (MG '08)
By Andrei Hutanu, Cornelius Toole
Issue Date:January 2008
This article analyzes the problem of optimizing access to and transport of large remote data through intelligent resource selection and configuration. With the availability of high speed optical networks, the main problem for remote data access is shifting...
