Parallel Processing Applied to Computational Electromagnetics

Abstract

MA SUMMARY OBJECTIVETo apply parallel processing techniques to a computational electromagnetic code and show that high-performance computing can improve the utility and efficiency of techniques used in ship electromagnetic designs. RESULTS" Efficient parallel matrix filling, factoring, and solving routines were developed, implemented, and evaluated. " The performances of the parallel matrix factoring and solving routines were independent of the structure being analyzed, whereas the performance of the parallel matrix filling routine was found to be very dependent on the structure being analyzed. " Several different techniques for mapping the matrix columns onto the processors were implemented and evaluated. * Efficiencies for all parallel algorithms increased as the size of the matrix being solved increased. " Performance comparisons were made between a MicroVax, the four transputer array, and the Convex Model C-220 mini-supercomputer. PAYOFFSSeveral payoffs have resulted, or will result, from the work done on this lED project: " A computer platform now exists for the efficient transition of computational electromagnetics to high-performance computing. The transputer array can be used to initiate parallelizing an existing computer code.
