What applications have insatiable bandwidth appetites? A challenge to scientists and technologists to optimally utilize 10Gbps experimental networks, with special emphasis on e-Science, Grid and Virtual Laboratory applications iGrid 2002 September 24-26, 2002, Amsterdam, The Netherlands:  Proposed iGrid 2002 Demonstrations To date, 12 countries/locations proposing 25 demonstrations: Canada, CERN, Germany, Greece, Japan, The Netherlands, Singapore, Spain, Sweden, Taiwan, United Kingdom, United States Applications to be demonstrated: art, bioinformatics, chemistry, cosmology, cultural heritage, education, high-definition media streaming, manufacturing medicine, neuroscience, physics, tele-science Grid technologies to be demonstrated: Major emphasis on middleware tool development for grids ― data management grids, visualization grids, data/visualization grids, computational grids, access grids, grid portals Other technologies to be demonstrated: optical networks as a data storage medium, logistical networking Network monitoring and measurement on the iGrid testbed iGrid 2002 September 24-26, 2002, Amsterdam, The Netherlands iGrid 2002 Canada and the United States:  iGrid 2002 Canada and the United States Space Over Time badpacket, Canada For this art project, four video streams are projected onto the floor ― using artificial life algorithms and composite images of current and ancient cartographic information, live video and prepared video. Topographical information is layered with weather patterns, demographic mappings, satellite imagery, live data from cameras placed around cities, subway maps, and more, creating a dynamic pattern that is constantly changing. Participants experience the slow time/space of Earth with the fleeting time/space of human activity. iGrid 2002 Canada, United States and The Netherlands:  iGrid 2002 Canada, United States and The Netherlands Wavelength Disk Drives (WDD) CANARIE, Canada Can-Sol Computer Corporation, Canada Electronic Visualization Laboratory, UIC, USA SARA and SURFnet, The Netherlands A WDD system treats an optical network as a storage medium. WDD is exploring the use of a video rendering application for its Phase 2, to be completed February 2003. iGrid 2002 is a milestone. WDD nodes will be deployed in Amsterdam, Chicago and several CA*net4 sites. iGrid 2002 Greece:  iGrid 2002 Greece Virtual Visit to the Site of Ancient Olympia Foundation of the Hellenic World (FHW), Greece University of Macedonia, Greece Greek Research & Technology Network In preparation for the 2004 Olympic Games hosted by Greece, the FHW, a cultural heritage institution based in Athens, is developing an accurate 3D reconstruction of the site of Olympia as it used to be in antiquity. if access to a high-performance network were available, the FHW’s museum could serve as a centre of excellence, delivering educational and heritage content to a number of sites worldwide. One of the most important monuments of the site is the Temple of Zeus, which houses the famous statue of Zeus, one of the seven wonders of the ancient world of which nothing remains today. iGrid 2002 Japan:  iGrid 2002 Japan TACC Quantum Chemistry Grid/Gaussian Portal National Institute of Advanced Industrial Science and Technology, Japan Gaussian code, used in computational chemistry, sometimes receives inadequate computational resources when run on large computers. The “Gaussian Grid Portal” efficiently utilizes costly computational resources without knowing the specifications of each system environment. It consists of a Web interface, meta-scheduler, computational resources, archival resources, and Grid Infraware. Grids allow one to compute from anywhere. 10Gb networking will eliminate the latency of using the portal to obtain adequate resources. iGrid 2002 The Netherlands:  iGrid 2002 The Netherlands Virtual Laboratory on a National Scale University of Amsterdam, The Netherlands This demonstration of upper middleware complements Grid services, enabling scientists to easily extract information from raw datasets utilizing multiple computing resources. The Virtual Lab software assigns various clusters (part of a distributed wide-area computer) parts of the problem (retrieval, analysis, visualization, etc.) To do data analysis and visualization on a distributed system, high bandwidth is a necessary prerequisite. iGrid 2002 The Netherlands and the United States:  D0 Data Analysis * NIKHEF, The Netherlands Fermi National Accelerator Laboratory (Fermilab), USA At D0 at Fermilab, raw data is coming from the detector. It is processed at a computer farm at Fermilab and the results are written to tape. Using NetherLight/StarLight, it would be possible to process the raw data on computers at NIKHEF. Raw data would be transferred to NIKHEF and results sent back to Fermilab. iGrid 2002 The Netherlands and the United States * May be withdrawn due to illness of one of the collaborators iGrid 2002 The Netherlands and the United States:  Griz: Grid Visualization Over Optical Networks Vrije Universiteit, The Netherlands Electronic Visualization Laboratory, UIC iGrid 2002 The Netherlands and the United States A distributed parallel rendering toolkit, Aura, remotely renders data on available graphics resources (notably in Chicago and Amsterdam) for local display. Interactive and collaborative applications have a near-real-time requirement. For interaction over long distances, network delay is a key factor. We expect a high-bandwidth optical network to have a highly constant (predictable) latency, which will make near-real-time behavior easier. iGrid 2002 The Netherlands, United Kingdom and the United States:  vlbiGrid Joint Institute for VLBI in Europe, The Netherlands Jodrell Bank Observatory, University of Manchester, UK Haystack Observatory, MIT, USA University of Manchester UK University College London, UK University of Amsterdam, The Netherlands,, iGrid 2002 The Netherlands, United Kingdom and the United States Very Long Baseline Interferometry (VLBI) is a technique in which an array of physically independent radio telescopes observes simultaneously to yield high-resolution images of cosmic radio sources. Today, magnetic tape transports data from telescopes to computers. The European VLBI Network (EVN) has access to multiple data sources that can deliver 1Gbps each and a data processor that can process 16 data streams simultaneously. High-speed networks would enable the EVN to achieve many-fold improvements in bandwidth. iGrid 2002 Singapore:  BioGrid* Bio Informatics Centre (BIC) National University of Singapore Kooprime, Singapore,,, iGrid 2002 Singapore * Tentative; looking for USA collaborators Bioinformatics is the study of the information content and information flow in biological processes and systems. Understanding gene and protein sequence information helps find new medical drug leads. Using BIC’s BioGrid (networked computational resources) and KooP Testbed technology, biologists can quickly build complex series of computations and database management activities on top of computational grids to solve real world problems. iGrid 2002 Spain and the United States:  HDTV Transmission over IP of a Cultural TV Production between Barcelona, Seattle and Chicago Universitat Politècnica de Catalunya (UPC), Barcelona, Spain University of Washington, USA Northwestern University, USA Starmaze, Spain iGrid 2002 Spain and the United States To demonstrate the first transcontinental HDTV set of productions over IP at 1Gbps, this group will broadcast cultural information (bi-directionally). Under consideration are acts of La Traviata, taped last year in Barcelona in HDTV, and a cultural performance of the Year Gaudi 2002, events celebrating the famous architect’s 150th birthday. iGrid 2002 Taiwan and Germany:  Image Feature Extraction on a Grid Testbed National Center for High Performance Computing, Taiwan Institute of Statistical Science, Academia Sinica, Taiwan High Performance Computing Center, Rechenzentrum Universität Stuttgart iGrid 2002 Taiwan and Germany For medical imagery (confocal laser-scanning microscopes, CT, MRI and PET), NCHC does image processing, analysis and 3D reconstruction. For biotechnology imagery (e.g., microarray biochips), NCHC uses a data clustering procedure for feature extraction that provides insight into an image, such as identifying diseases caused by some protein. Grid techniques enable the use of distributed computing resources and shared data. High-speed networks enable fast processing; typical medical doctors want the procedure accomplished in 5 seconds for use in daily operations. 3D modeling of a cockroach brain acquired from a confocal laser-scanning microscope, visualized in the CAVE with COVISE software iGrid 2002 United States:  iGrid 2002 United States Telescience Portal National Center for Microscopy and Imaging Research (NCMIR), UCSD Develop a richly integrated, closed-loop telescience application. Using a remote electron microscope, acquire a series of digital images of a specimen. Create a tomographic 3D reconstruction. Enable the user to steer the acquisition and reconstruction towards better results by using information feedback. iGrid 2002 United States and CERN:  iGrid 2002 United States and CERN Insatiable Bandwidth Grid-Enabled Object Collection Analysis for Particle Physics Caltech, USA CERN Extend an SC’2001 “bandwidth greedy” demo to an “insatiable bandwidth” demo: Enabled particle physicists at SC’2001 in Denver to interactively analyze 105 GB of physics event data stored at two Tier 2 centers (at Caltech and SDSC), achieving a peak throughput of 29.06 MByte/sec. The demo showed key elements of the CMS Data Grid system that the CMS particle physics experiment is building, in collaboration with several Data Grid reseach projects like GriPhyN, PPDG, and the EU DataGrid. iGrid 2002 United States, Canada, United Kingdom, Sweden, Netherlands:  iGrid 2002 United States, Canada, United Kingdom, Sweden, Netherlands Terra Wide Data Mining Testbed (TWDM) Laboratory for Advanced Computing, UIC Dalhousie University, Halifax, Canada Imperial College of Science, Technology & Medicine, University of London SARA, The Netherlands Center for Parallel Computers, Royal Institute of Technology, Sweden The Terra Mining Testbed (TMTB) uses high-performance clusters linked by wide-area high-performance networks to provide the data and compute services required. iGrid 2002 United States and The Netherlands:  iGrid 2002 United States and The Netherlands Visual Tera Mining Laboratory for Advanced Computing, UIC Electronic Visualization Laboratory, UIC Visualize multiples of gigabytes of data in near real time. iGrid 2002 United States and The Netherlands:  iGrid 2002 United States and The Netherlands TeraVision: Visualization Streaming over Optical Networks Electronic Visualization Laboratory, UIC, USA SARA and Vrije University, The Netherlands TeraVision will demonstrate tiled cluster-to-cluster graphics streaming. This image, from SC’99, depicts the University of Minnesota’s PowerWall running an interactive collaboration developed by UIC and the US DoE ASCI project. This project will stream pre-rendered high-resolution (gigabit-level) graphics from Chicago to Amsterdam. In 5 years, TeraVision will be like Television, where scientists simply dial into their streamed visualization. For a 20-node tiled display, we need ~10Gbps. TeraVision can be used with the Access Grid; to share a visualization with 5-10 sites, we will need <100Gbps. iGrid 2002 United States and The Netherlands:  iGrid 2002 United States and The Netherlands Photonic TeraStream International Center for Advanced Internet Research (iCAIR), Northwestern University, USA University of Amsterdam, The Netherlands This project showcases new technologies and techniques being developed on the StarLight/NetherLight testbed and on OMNInet in support of high-performance digital media and extremely-high-performance data transfer. This 10Gbps capability is being used to develop a reference model for a next-generation core optical metro network infrastructure. This infrastructure will allow access to and dynamic interaction with very large amounts of data. Our application can utilize multi-Gbps today; in five years, we hope to utilize multiple 10GigE streams. iGrid 2002 United States, United Kingdom and The Netherlands:  iGrid 2002 United States, United Kingdom and The Netherlands Dynamic Load Balancing of Structured Adaptive Mesh Refinement (SAMR) Applications on Distributed Systems ECE Department, Northwestern University, USA Nuclear and Astrophysics Laboratory, Oxford University ENZO is one of the successful parallel implementations of structured AMR (SAMR) for use in astrophysics and cosmology. We propose a framework for dynamic load balancing on distributed systems and implement the scheme in ENZO code. To sufficiently simulate the formation of galaxies, taking communication and latency issues into consideration, the bandwidth must be ~100Gbps. iGrid 2002 United States and the United Kingdom:  iGrid 2002 United States and the United Kingdom The Universe: Distributed Virtual Collaboration & Visualization NCSA, UIUC University of California, San Diego Information Sciences Institute, University of Southern California Hayden Planetarium, New York, NY, USA Stephen Hawking Laboratory, University of Cambridge, UK Virtual Director and related technologies enable multiple users to remotely collaborate in a shared, astrophysical virtual world. Users are able to collaborate via video, audio, avatars and through discreet interactions with the data. Collaborators can see and hear each other through streaming video, audio and 3D avatar representations. iGrid 2002 United States:  iGrid 2002 United States Collaborative Visualization over the Access Grid Argonne National Laboratory/University of Chicago, USA, This project ties the Access Grid and the TeraGrid together, enabling scientists to collaboratively and interactively analyze time-varying datasets that are multiple terabytes in size. In addition to supporting audio and video, the Access Grid connects users with the output of visualizations ― to explore datasets, create isosurfaces, look at particle traces, and move cutting planes. Current AG sessions consume ~30Mbps; higher bandwidth will enable higher resolution video, higher quality audio, and more advanced applications. iGrid 2002 United States:  iGrid 2002 United States Video IBPster LoCI Lab, University of Tennessee, USA Logistical Networking is defined as the global scheduling and optimization of data movement, storage and computation. We develop tools that are dedicated to fast data transfer, such as the Data Mover, using as much bandwidth as is available. For iGrid, a geographically distributed abstraction of a file is replicated, transported to depots that are closer according to network proximity values calculated in real-time using NWS, and downloaded from the nearest site in a completely transparent way for a high-level application. iGrid 2002 United States:  iGrid 2002 United States PAAPAB Res Umbrae, USA University at Buffalo, USA PAAPAB (Pick An Avatar, Pick A Beat) is a shared virtual-reality disco environment inhabited by life-size puppets (user avatars). Currently, due to limited bandwidth, the disco motions and music are cached and played back locally at each client rather than streamed continuously. Our theoretical bandwidth needs are in the 50-100 Mbps range (for up to 12 participants, 40 puppets, and high-quality audio). Assuming 10Gb, the limiting factor becomes the number of people who have access to VR equipment and network connections. Of course, latency and jitter are also issues to understand. iGrid 2002 United States, Germany, United Kingdom, Japan and Taiwan:  iGrid 2002 United States, Germany, United Kingdom, Japan and Taiwan Distributed, On-Demand, Data-Intensive and Collaborative Simulation Analysis Sandia National Laboratories, USA Pittsburgh Supercomputing Center, USA Tsukuba Advanced Computing Center, Japan National Center for High-Performance Computing, Taiwan High Performance Computing Center Stuttgart, Germany Manchester Computing Centre, UK, This project focuses on grid-enabling technologies for distributed computing, on-demand computing, data-intensive computing and collaborative analysis. These centers are developing a system that delivers computation and data exploration of very large datasets over a high performance network. All collaborative graphics sessions will be complemented with audio/video conferencing using an Access Grid interface. Applications to be demoed include manufacturing and bio-informatics iGrid 2002 United States:  iGrid 2002 United States Beat Box Indiana University, USA Beat Box presents networked CAVE participants with a playful arena of interactive sound machines. Each of three machines has a unique periodic duration and controls, respectively, percussion, ambient loops and bass sounds. iGrid 2002 United States and CERN:  iGrid 2002 United States and CERN Replication Mechanisms for High Energy Physics Experiments Argonne National Laboratory, USA Fermi National Accelerator Laboratory, USA Caltech, USA USC Information Sciences Institute, USA CERN (EU DataGrid Project) Condor Group, University of Wisconsin, USA Approximately 10000 scientists from 100s of universities in over 50 different countries will participate in the analysis of Large Hadron Collider (LHC) data. To make processing the data efficient, it might be desirable to create remote read-only copies (replicas) of data elements (files) to reduce access latency, increase robustness, or increase the probability that a file can be found associated with idle computing capacity. Tools that accomplish this are presented: GridFTP (a transport mechanism for moving the data over the WAN), a replica location service (RLS), and GDMP (a simple, high-level management system).
