Abstract:

A methodology was desired for optimizing the Numerical Electromagnetics CodeNEC on a given platform. The platform chosen was the Convex mini-supercomputer. The matrix fill and factor times were the gauges of optimizing for speed. The software tool for choosing where to optimize was the profiler that comes with the FORTRAN compiler. NEC2, NEC3, and NEC4 were evaluated. The test cases were models of 44,300, 722, and 2286 segments. Three levels of built-in compiler optimizations were used. Additional optimizations were sought. The greatest speedup in runtime came with the use of LINPACK library routines specifically optimized of the Convex.
