Abstract
THE FINITE-ELEMENT APPROACH TO STRUCTURAL ANALYSIS HAS BEEN CONSIDERED EFFICIENT AND COMPREHENSIVE FOR MANY YEARS. THE NASA-DEVELOPED STRUCTURAL ANALYSIS PROGRAM NASTRAN IS IN THE FOREFRONT FOR USE IN SUCH ANALYSES. IN THIS PROJECT, A DESIGN THAT WOULD ALLOW NASTRAN TO WORK EFFICIENTLY ON COMPUTERS THAT HAVE A MASSIVELY PARALLEL ARCHITECTURE WILL BE STUDIED. THE EFFORT WILL INCLUDE AN ANALYSIS OF THE CAPABILITIES OF EXISTING COMPUTERS WITH A MASSIVELY PARALLEL ARCHITECTURE, DETERMINATION OF EFFICIENT MATRIX ALGORITHMS, DETERMINATION OF AREAS OF CODE THAT COULD BE EXECUTED IN PARALLEL, DETERMINATION OF POSSIBLE PARALLELIZATION AT THE NASTRAN COMMAND LANGUAGE LEVEL, AND A DEFINITION OF THE ADDITIONAL NASTRAN I/O FUNCTIONS AND EXECUTIVE CONTROL FUNCTIONS REQUIRED TO INSTALL OPTIMAL PARALLELIZATION TECHNIQUES.
