Major FY 1993 Accomplishments 



3 Six to eight new Grand Challenge Applications 

 Groups funded (listed in Side Bar). 



This program activity was initiated in FY 1992, with 

 awards made to multidisciplinary groups of scien- 

 tists and engineers whose activities integrated dis- 

 ciplinary research with the design of models, algo- 

 nthms, and software for high performance comput- 

 ing systems. See Side Bar for areas in which 

 awards were made. 



J Research projects on techniques and environ- 

 ments for scalable parallel and distributed hetero- 

 geneous computing, collaboration technologies, 

 evaluation of High Performance Fortran, program- 

 ming language standards, and user environment 

 components. 



aMetacenter implementation in selected areas at 

 the NSF high performance computing centers to 

 provide new opportunities for the combined use 

 and shared management of these systems and 

 requisite supporting technologies. 



3 Deployment and configuration of scalable parallel 

 systems for mainstream scientific computing at the 

 NSF centers. 



jNREN awards for Network Information Services; 

 recompetition of the NSFNET Backbone; promul- 

 gation of computer security measures; evaluation 

 of the Network Access Point (NAP) concept; 

 regional networks; and testbeds for teaching and 

 education.
