Overview of the Five HPCC Components 



Five equally important, integrated components represent the key areas of high performance computing 

 and communications: 



HPCS - High Performance Computing Systems 



Extend U.S. technological leadership in high performance computing through the development of 

 scalable computing systems, with associated software, capable of sustaining at least one trillion opera- 

 tions per second (teraops) performance. Scalable parallel and distributed computing systems will be 

 able to support the full range of usage from workstations through the largest scale highest perfor- 

 mance systems. Workstations will extend into portable wireless interfaces as technology advances. 



NREN - National Research and Education Network 



Extend U.S. technological leadership in computer communications by a program of research and 

 development that advances the leading edge of networking technology and services. NREN will 

 widen the research and education community's access to high perfonnance computing and research 

 centers and to electronic information resources and libraries. This will accelerate the development 

 and deployment of networking technologies by the telecommunications industry. It includes nation- 

 wide prototypes for terrestrial, satellite, wireless, and wireline communications systems, including 

 fiber optics, with common protocol support and applications interfaces. 



ASTA - Advanced Software Technology and Algorithms 



Demonstrate prototype solutions to Grand Challenge problems through the development of advanced 

 algorithms and software and the use of HPCC resources. Grand Challenge problems are computation- 

 ally intensive problems such as forecasting weather, predicting climate, improving environmental 

 monitoring, building more energy-efficient cars and airplanes, designing better drugs, and conducting 

 basic scientific research. 



IITA - Information Infrastructure Technology and Applications 



Demonstrate prototype solutions to National Challenge problems using HPCC enabling technologies. 

 IITA will support integrated systems technology demonstration projects for critical National 

 Challenge applications through development of intelligent systems interfaces. These will include sys- 

 tems development environments with support for virtual reality, image understanding, language and 

 speech understanding, and data and object bases for electronic libraries and commerce. 



BRHR - Basic Research and Human Resources 



Support research, training, and education in computer science, computer engineering, and computa- 

 tional science, and enhance the infrastructure through the addition of HPCC resources. Initiation of 

 pilot projects for K-12 and lifelong learning will support expansion of the Nil.
