Simulated temperature profile for a 

 three-dimensional fiypersonic re-entry 

 body traveling at an altitude of 100 kilo- 

 meters, a speed of Mach 24. and an 

 angle of attack of 10 degrees. 

 Performed on the Intel Touchstone 

 Delta at CSCC. the simulation 

 employed 70 million particles and all 

 512 of the Delta's processors running 

 for 50 minutes. 



HPCC Program, and 3) specify an open non-proprietary 

 architecture that will facilitate the emergence of a nation-

IITA: Toward a National Information Infrastructure 



NASA is committed to broadening its participation in key 

 areas of research and development of prototype solu- 

 tions to National Challenge applications. NASA is selec- 

 tively augmenting on-going programs that can contribute 

 to an early start-up of these prototype systems in appli- 

 cations such as education and lifelong learning, digital 

 library technology, manufacturing and industrial design, 

 and access to widely available databases of Earth and 

 space science data. NASA participates in each of the 

 four IITA elements. 



BRHR: Fostering High Performance Computing 

 Research 



NASA's BRHR component fosters research into new 

 theory and application of high performance computing. 

 These activities will leverage current research efforts in 

 high performance computing at NASA research insti- 

 tutes and universities. 



Major FY 1993 Accomplishments and Activities 



Concurrent SuperComputing Consortium (CSCC) 



NASA played an active role in the Consortium during its 

 first year of operation. Use of the Consortium's Intel 

 Touchstone Delta supercomputer has enabled major 

 advances in several scientific and engineering applica- 

 tions including the processing of three-dimensional 

 images of Venus taken by the Magellan satellite at the 

 rate of four frames per second - thus putting real-time 

 image processing within reach. Other accomplishments 

 on the Delta include the largest direct numerical simula- 

 tion of the time-dependent compressible Navier-Stokes 

 equations and the largest three-dimensional compress- 

 ible turbulence simulations for high Reynolds numbers.
