Planned Demonstrations

HPDC-4 Demonstration 3:30-5:00pm, August 3, 1995 Ritz-Carlton Hotel, Pentagon City, Virginia

Sponsors: WorldCom, NYNEX, Fore Systems, Syracuse University and Rome Labs

The computer network of HPDC-4 conference site will be connected to the NYNET Wide Area Network) testbed as shown in the attached figure. The technology used to implement this high speed network is based on two leading-edge communications technologies: SONET and ATM. SONET -- Synchronous Optical NETwork -- permits vast streams of information to be transported on fiber-optic cables as pulses of light at rates of billions of bits per second. Additionally, SONET provides sophisticated fault tolerance and management features that are necessary to provide the medical and business industries with the uninterrupted quality of service they require. ATM -- Asynchronous Transfer Mode -- is a digital switching technology that segments a digital information stream (voice, video, and/or data) into fixed size cells, and then switches these cells in real-time to their intended destination. ATM technology provides a means of offering end users bandwidth-on-demand and a greater level of aggregate traffic (approaching terabits per second -- one tera is one thousand billion) to be carried and potentially reduces the cost of providing high speed network access to the end user.

NYNET provides interconnection between many of the New York State's leading educational institutions (Syracuse University, Cornell University, Columbia University, SUNY Stonybrook, Polytechnic Institute of New York), government labs (Rome Laboratory, Brookhaven National Laboratories), industry labs (NYNEX Science and Technology, Grumman, Cold Spring Harbor Research Laboratories), Museum of Science and Technology (MOST), and several medical institutions in New York. Most of the wide area portion of the NYNET operates at speed OC 48 (2.4 Giga bits per second) while each site is connected with two OC 3 links (155 Million bits per second).

The ATM link from the conference site to the NYNET testbed will enable us to access the high performance computers (CM-5, IBM-SP2, NCUBE, MasPar, Intel IPSC 860) and workstations available at the Northeast Parallel Architectures Center (NPAC) at Syracuse University. With this connectivity, we will be able to demonstrate several HPCC applications that have been developed by Syracuse University researchers and in collaboration with Rome Laboratory.

Demonstration Overview

The HPDC-4 demonstration will include the following applications:

Distributed Computing Applications

In this demo, we demonstrate how ATM network can be used to run distributed applications (concurrent multitarget tracker, linear equation solver, financial modeling, electromagentic scattering simulation, etc.) on computers geographically dispersed across wide area network.

Virtual Distributed Computing Environment

In this demo, a virtual computing environment is dynamically formed using resources available at HPDC-4 conference site, Syracuse University and Rome Laboratory to provide computing and storage requirements of large scale HPCC applications.

Video On Demand (VOD)

In this demo, we show how Video Servers being developed at Syracuse University can be accessed from remote sites via a high speed ATM network.

WebWork Server Demo

In this demo, we will demonstrate WebWork and prototype in terms of NPAC WebTools servers - a collection of CGI-extended Web servers with support for document authoring and management, HyperWorld navigation and e-mail handling. WebWork servers can be accessed by any conventional browser. Integration with interactive browsers such as HotJava is being currently explored and demonstrated in a set of Java demos that illustrate early prototoypes of the following WebWork tools: visual interactive dataflow editor, software project manager, desktop publisher, neural network for hand-written character recognition.

Web Search Demo

The "Web Search" Demo set consists of total six demonstrations in the areas of 1) Integration of relational database management system (RDBMS) and Web technologies; 2) Web Search Systems where we demonstrate full-text search capability of three different indexing/search systems under Web: An Oracle's TextRetrieval System, A WWWWAIS Interfacek, and A Harvest Broker.
In additioon, we will also demonstrate running parallel queries on Oracle 7 parallel server on nCUBE2 at NPAC. This demo is also integrated under the web.

Living Textbook Project Demo

The Living Textbook is a multidisciplinary project to demonstrate leading technologies in the K-12 classroom of the future. Using state of the art information technologies, The Northeast Parallel Architectures Center and the School of Education at Syracuse University deliver video, images, and text to the classroom to prototype interactive, information on-demand systems and their integration into K-12 curricula.

Telemedicine Networking Demo

Rome Laboratory will be demonstrating Telemedicine application in collaboration with SUNY-Health Science Center Syracuse (SUNY-HSC), NY. This demo will be demonstrating distributed collaboration using both wireless and land-based Asynchronous Transfer Mode (ATM) networks in support of Telemedicine. The demonstration will show a collaborative environment, based on a medical situation that shows how high speed networks can be used in transferring medical images and consultation.

Effective Fault Tolerant Parallel Processing Demo

In this demo, a Temple University research project based on Passive Object-Flow Programming (POFP) will be demonstrated. This demonstration shows the inherent advantages of POFP in fault tolerance and load balancing. A number of other critical utilities are also to be shown, such as security tools, debugging tools, and personal processor pool management tools.


Mentat is an object-oriented parallel processing system designed to directly address the difficulty of developing architecture-independent parallel programs. Mentat combines a medium-grain, data-driven computation model with the object-oriented programming paradigm and provides automatic detection and management of data dependencies.


The Next Logical Step Toward a Worldwide Virtual Computer: The Legion project at the University of Virginia is an attempt to provide system services that provide the illusion of a single virtual machine to users, a virtual machine that provides both improved response time and greater throughput. Legion will consist of workstations, vector supercomputers, and parallel supercomputers connected by local area networks, enterprise-wide networks, and the National Information Infrastructure.
