3. iGrid: The International Grid
iGrid highlights achievements in grid architecture development and application advancements in science, engineering, cultural heritage, distance education, media communications, and art and architecture
24 demonstrations featuring technical innovations and application advancements requiring tele-immersion, large datasets, distributed computing, remote instrumentation, collaboration, human/computer interfaces, streaming media, digital video and high-definition television
14 regions: Canada, CERN, Germany, Greece, Japan, Korea, Mexico, The Netherlands, Singapore, Spain, Sweden, Taiwan, United Kingdom, USA
The SC’98 International Grid (iGrid) research demonstrations showcase international collaborations using advanced high-speed networks, enabling researchers to work together, whether their colleagues live across the country or across the ocean, and to access geographically-distributed computing, storage, and display resources. The iGrid booth, jointly sponsored by the Electronic Visualization Laboratory at the University of Illinois at Chicago and Indiana University, provides global connectivity so collaborators from the United States, Australia, Canada,
Germany, Japan, The Netherlands, Russia, Singapore, Switzerland, and Taiwan can demonstrate their use of advanced networks to solve complex computational problems.
Enabling these international demonstrations is the National Science Foundation (NSF) sponsored initiative STAR TAP—the Science, Technology And Research Transit Access Point [ Started in 1997, STAR TAP anchors the NSF vBNS (very high-speed Backbone Network Service) international program. Networks from Canada (CAnet-2), Singapore (SingaREN), Taiwan (TANet), Russia (MirNET), and the Asian-Pacific Advanced Network consortium (APAN) are connected; Indiana University is the lead institution of the APAN-USA joint venture, named TransPAC [ STAR TAP connections to the Nordic countries (NORDUnet), The Netherlands (SURFnet), France (RENATER), and Israel are imminent. Other USA federal
agency advanced networks, notably the Department of Defense DREN, Department of Energy ESnet, and NASA NREN are also connected to STAR TAP. STAR TAP is managed by the Electronic Visualization Laboratory, Argonne National Laboratory, the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign, and Chicago’s Ameritech Advanced Data Services.
The Electronic Visualization Laboratory and Indiana University, members of NCSA’s National Computational Science Alliance partnership, are working to advance the development of the International Technology Grid. The Grid is a prototype 21st century computational and information infrastructure integrating high-performance computers, visualization environments, remote instruments, and massive databases via high-speed networks to support advanced applications.

Beckman Institute, University of Illinois at Urbana-Champaign, USA
ECE, UIUC, USA
Computer Science, UIUC, USA
This project streams 2D and 3D images from Argus, a room surrounded with cameras, into the CAVE using Crumbs volumetric rendering software. The project explores tradeoffs between sending 3D data volumes versus low-bandwidth, low-latency stereo pairs. This demonstration showcases how parallel video acquisition lends itself to viewing 3D scenes in different time zones.
Argus consists of 64 optical cameras imaging a 14-foot diameter, 8-foot tall cylindrical volume. A 32-node Beowulf Linux cluster controls the camera array and performs image-processing algorithms. Argus delivers two kinds of data: full 3D data volumes (128 points per side; 2-8 volumes per second) and stereo image pairs for any viewpoint in the cylindrical volume.
