FY 1994 Plans 



NSF will continue to support HPCC basic research activ- 

 ities, metacenter implementation, Grand Challenge 

 Application Groups, postdoctoral research associate- 

 ships, and broader access to high performance comput- 

 ing research resources for researchers, students, and 

 educators at all levels. Support for NREN development 

 will continue to meet special NSF obligations and 

 responsibilities set forth in the HPCC Program plan, 

 including the development of gigabit testbeds. New 

 activities will support the migration of technologies and 

 capabilities developed in the original HPCC Program 

 component areas to address specific applications asso- 

 ciated with such areas as health care, lifelong learning, 

 digital and electronic libraries, and manufacturing. 



HPCS support will focus on: 



^Developing new systems level design tools that 

 have increased functionality, are highly automat- 

 ed, and accept high level specifications and algo- 

 rithms as input. 



-"Novel computing system design approaches 

 drawing on expertise in architecture, systems soft- 

 ware, storage technology, I/O subsystems, and 

 networking technologies. 



J Optical communications devices and systems. 



-"Advanced computer and information technologies 

 to enable distributed design and intelligent manu- 

 facturing of objects. 



J Systems-level issues in understanding, modeling, 

 and integrating component manufacturing tech- 

 nologies. 



NREN activities will include: 



-" Development of a very high speed backbone. 



^Increasing the number of network access points 

 (NAPs). 



J Funding, improving, and providing new services 

 for mid-level networks.
