Abstract:

COMPUTATIONAL FLUID DYNAMICS (CFD) CODES HAVE BECOME IMPORTANT DESIGN AND ANALYSIS TOOLS FOR ENGINEERS, PARTICULARLY IN THE AEROSPACE INDUSTRY. CFD CODES, HOWEVER, ARE SEVERELY LIMITED BY THE COMPUTING RESOURCES OF PRESENT-DAY SUPERCOMPUTERS. IT IS ESTIMATED THAT A THREE ORDER-OF-MAGNITUDE INCREASE IN COMPUTER SPEED IS NECESSARY FOR PERFORMING PRACTICAL ENGINEERING VISCOUS-FLOW ANALYSES OF FULL AIRCRAFT CONFIGURATIONS. SOME PRESENT SUPERCOMPUTERS HAVE NEARLY REACHED THE THEORETICAL LIMIT OF UNIPROCESSORS, MAJOR INCREASES IN COMPUTING SPEED WILL MOST LIKELY RESULT FROM PARALLEL PROCESSING. NEW ALGORITHMS MUST BE DEVELOPED FOR SOLVING THE CFD EQUATIONS ON PARALLEL COMPUTERS. IN PHASE I SEVERAL PARALLEL ALGORITHMS WILL BE DEVELOPED FOR SOLVING THE 3D NAVIER-STOKES EQUATIONS AND IMPLEMENTED IN PROTOTYPE COMPUTER CODES. THESE CODES WILL BE APPLIED TO A COMPUTATIONALLY DEMANDING FLOW PROBLEM. THE PERFORMANCE OF EACH ALGORITHM WILL BE MEASURED AND EVALUATED ON THE ENCORE MULTIMAX PARALLEL COMPUTER AND ENCORE'S (DARPA FUNDED) PRELIMINARY LARGE-ARRAY MULTIPROCESSOR (LAMP)--THE DUAL MULTIMAX. IN PHASE II AND III REFINEMENT OF THE MOST PROMISING ALGORITHM(S) WILL BE CONDUCTED AND IMPLEMENTED INTO A PRODUCTION COMPUTER CODE FOR SOLVING THE 3D NAVIER-STOKES EQUATIONS ON ENCORE'S ULTRAMAX (A 128 PROCESSOR LAMP BEING DEVELOPED WITH DARPA FUNDING).
