Description:
iHDTV™ is a software suite consisting of software modules that work with commercially available components to capture, packetize and transport high-definition video in various formats over Internet Protocol networks, spanning the range of HDTV quality levels, with the goal of providing wider access to high-definition content. Developed by ResearchChannel along with the University of Washington, iHDTV™ was first demonstrated in 1999.

Since that time, the software suite been expanded to enable and expedite efficient streaming with data at rates of up to 1.5Gbps, which is sufficient to transfer uncompressed 1080i high-definition video. The iHDTV™ code is designed to require minimum overhead to achieve low latency. Its modular design can easily support new devices and flexible modes of operation, and the code is highly configurable.

ResearchChannel’s iHDTV™ project is designed to explore how research and academic endeavors — and the world in general — would change if studio-quality HD video could be sent over a general-purpose Internet. More fundamentally, the project explores the intersection of network, video and server technologies where near real-time distribution of extremely high-quality images is required.

ResearchChannel has been experimenting with ways to develop and integrate technology and techniques for the distribution of high-quality video over the Internet. And over time, the definition of high-quality, and the corresponding requirements for network capacity, have dramatically increased.

UW's Internet HDTV project is pushing the envelope on several fronts. Multiple system integration challenges have been encountered, from PC performance problems to Gigabit Ethernet incompatibilities. As the project continues, ResearchChannel hopes to gain insights that will help guide current network quality-of-service debates, questions of the relationship between quality and latency and limitations of current PC architectures. ResearchChannel is also exploring applications besides HD television (such as collaboration, telemedicine and interactive visualization) which would benefit from iHDTV™ technology.

The most recent development in iHDTV™ is an open source collaboration with several ResearchChannel participant and industry partners to further develop the capability and scope of the iHDTV™ software tool set

Role of Internet2:
Internet2 Abilene will be used for some of the demo traffic.

Description:
The SURA Coastal Ocean Observing & Prediction (SCOOP) program is building cyberinfrastructure (CI) to enable advanced event-driven ensemble forecasting of the coastal impacts from storms and hurricanes in the southeastern United States, integrating real-time distributed data and computer models for the East and Gulf coasts of the United States. This demonstration showcases the SCOOP system, which employs a service oriented architecture to integrate data archive and transport services, a metadata catalog, resource and application management, distributed computational resources, and the scientific simulation codes modeling coastal phenomena. Triggered by scientist interaction through a Portal and advisories from the National Hurricane Center, this demonstration shows how the SCOOP system can automatically build, schedule and deploy an appropriate ensemble of models for water level and wave properties, driven by real time wind data. The demonstration highlights the ability to re-prioritize resource utilization based on data driven criteria - for example, storm intensity or proximity to the coast. Depending on the urgency of the situation and level of the storm, resources are scheduled with different levels of priority, in the extreme case SCOOP models preempting already running jobs. Various products built from model data and real time observations are shown through aggregating sites such as OpenIOOS.org. A distributed operational system such as SCOOP allows modelers to do multiple ensemble runs in order to increase the accuracy of a storm path prediction as well as providing the forecast earlier allowing for more efficient evacuation and preparation. The demonstration run will last approximately 20 to 30 minutes and use two desktop systems. It will be repeated as necessary.

Role of Internet2:
This distributed application is dependant upon I2 underlying most of the member organizations in order for the ensemble modelling (many iterations)to be done in time to allow emergency services organizations to evacuate or otherwise prepare for hurricanes and significant weather events. Using terascle computing facilities connected by the I2 network allows modelling methods to be employed which have not been possible even 18 months ago. While the actual distributed computations can be done over the regular internet, it is impossible to gather data, distribute data, compute, distribute results, visualize, analyze, and repeat the cycle multiple times on a short enought time cycle to be effective

Funding Organization:
The Ohio Board of Regents

Description:
OARnet is partnering with The Ohio State University's Center for Accelerated Maturation of Materials (CAMM) to make a set of world's most powerful electron microscopes remotely accessible to researchers and industries over the Internet. Since the electron microscopes are valuable and expensive resources ($450,000 - $4 Million), remote access possibilities have the potential of drastically shortening the development process of new materials and thus significantly reducing costs for industry partners, research labs and students at other university campuses.

Remote access of the OEM Application is an exciting network-dependent application, the likes of which, have never been seen or supported before. The following challenges describe this complex and demanding application: The OEM application requires high resolution video image transfers over network paths between CAMM and the remote end-user sites. These image transfers consume significant computing for real-time video processing and require approximately 30Mbps network bandwidth per session, making this application more demanding than High-definition Videoconferencing or even IPTV. In addition, the OEM application requires stringent and real-time control of mouse and keyboard to manipulate the application controls. Improper mouse and keyboard controlling could result in physical damages to the electron microscope equipment that could cost in excess of $100,000 to fix. Even more demanding is the fact that the end-user Quality of Experience (QoE) is extremely sensitive compared to the QoE demands of any other network-dependent application.

Role of Internet2:
OARnet is ensuring that the networking capabilities of TFN are fully leveraged for successful remote access experience of the OEM application within Ohio. Remote access can also be leveraged by Industry, Research Lab and University partners using the Internet2 network infrastructure anywhere in the US and other parts of the world.

Description:
The START Collaboratory integrates access to gigabytes of searchable data and images from the Sloan Digital Sky Survey and SkyServer tools into Web-based collaborative research journals that can be shared and discussed online. From these research journals, students can request observations from Internet controlled telescopes. These observations can be viewed with the START Web visualization and measurement tool. What distinguishes this approach is being able to bring real data and real tools to students in ways that engage them in authentic research; generating useful scientific results just as professional astronomers do--learning science by doing science.

Role of Internet2:
While the user's connection to the START Collaboratory is over the commodity Internet, the START Collaboratory uses Web services to integrate data, tools and applications available on Internet2 into a Web-based collaborative research environment. Processing, queries and calculations are done on servers and returned to online collaborative research journals. Large FITS files are moved across Internet2 from remote telescopes, databases and servers to the START VisTool for Web-based visualization and measurement.

Description:
SURAgrid is evolving into a generalized, regional education and research infrastructure that is positioned to become an essential tool for scientific progress. With support from the National Science Foundation (OCI-054555), SURAgrid is also establishing a representative application set to utilize and demonstrate SURAgrid’s current functionality and help direct and catalyze future design and development. SURA will provide demonstrations of applications that illustrate the diversity of the application set which currently is comprised of GSU Multiple Genome Alignment, UAB BLAST, UNC/SCOOP Coastal Modeling with ADCIRC, NCState EPANET Optimization/Simulation and ODU Bio-Electric Simulator. A summary of these applications is included directly below and additional details are available at

UNC/SCOOP: Storm-Surge Modeling with ADCIRC – ADCIRC is a finite element method shallow water model for computing tidal and storm surge water level and depth-averaged currents associated with these phenomena. Grid environments such as SURAgrid are ideal for the ensembles in applications like ADCIRC, which is one of a set included under SCOOP (SURA Coastal Ocean Observing and Prediction) program that is focused on improving predictions of coastal phenomena.
Project Partners: University of North Carolina Marine Science, Renaissance Computing Institute (RENCI), MCNC, SAIC

NCSU: EPANET Simulation-Optimization for Threat Management in Urban Water Systems – This application incorporates dynamic demand data, in real-time, into a simulation-optimization process for contamination threat management in drinking water distribution systems. The nature of this work is highly compute-intensive and requires multi-level parallel processing via computer clusters and high-performance computing architectures such as SURAgrid. Simulation-Optimization with EPANET is part of a multi-disciplinary, three-year NSF-funded DDDAS (Dynamic Data-Driven Application Systems) research project to develop a cyberinfrastructure system that will both adapt to and control changing needs in data, models, computer resources and management choices facilitated by a dynamic workflow design.
Project Partners: North Carolina State University; University of Chicago; University of Cincinnati; University of South Carolina

ODU: Bio-electric Simulator for Whole Body Tissues – This application is designed to simulate the response of a “whole body tissue” model to potential/current stimulus through direct electrode contact. The Electrical and Computer Engineering and Office of Computing and Communications Services departments at Old Dominion University are using SURAgrid to grid-enable this application to utilize concepts such as work-flow and virtual data methods. The Bio-electric Simulator, which is both computation and data intensive, has been demonstrated to scale with the number of processors and can thus benefit from the accessibility to the additional computational resources of SURAgrid.

GSU: Multiple Genome Sequencing & Alignment – This multiple sequence alignment algorithm application takes a number of genome sequences as input and gives an aligned sequence based on their structure by using a pairwise alignment algorithm. When run on grids like SURAgrid, carefully designed and grid-enabled algorithms like this, which implement a memory efficient method for computation and are also parallelized efficiently so that the workload is well distributed on grids, afford bioinformatics users a performance comparable to cluster environments while giving them added flexibility and scalability.

UAB: Grid-Enabled Distributed BLAST – BLAST is a database search application for matching protein and nucleotide sequences. Maximizing the throughput of searches is key to improving research results. This distributed implementation of BLAST uses the DynamicBLAST Meta-scheduler to select appropriate grid resources for select query strings. Globus is used for job staging, submission and retrieval. ncbiBLAST performs the computations. Jobs are submitted using a web-based interface that leverages campus identity credentials via Pubcookie and manages grid authentication on behalf of the user via MyProxy, providing a simplified user authentication experience.

Role of Internet2:
The applications that will be included in this representative sample are resource and compute intensive. The SURAgrid infrastructure is a grid network of Internet2 connected SURAgrid participants. To perform well in this type of grid environment, the applications that will be included in this demo require the bandwidth of Internet2.
