Benchmarking of Modern High-Performance Full-Wave CEM Codes
In computational science and engineering, benchmarks consisting of precisely defined problems, quantities of interest, and reliable reference results can be used to: (i) Verify/validate computational methods and identify errors/defects in their software implementations. (ii) Quantify the performance of an entire computational system (hardware, software, algorithms) or one of its components. (iii) Objectively evaluate the relative (dis)advantages of alternative computational systems or components. (iv) Support the development, adoption, or purchase of new computational systems or components, in part by informing the developers and users of their limitations as well as capabilities.
The authors recently introduced and continue to expand a radar cross section (RCS) benchmark suite—containing a select set of problems together with performance measures and reference data from analytical methods, measurements, and simulations—for computational electromagnetics (CEM) benchmarking. These benchmark problems are primarily focused on aerospace applications of CEM codes on modern computers and aim to quantify their accuracy-cost tradeoff as the problem difficulty increases in four dimensions: Geometric complexity, material diversity/fidelity, size, and frequency.
At the HPCMP User Group Meeting, the authors will use the RCS benchmark suite to demonstrate benchmarking of a modern full-wave CEM code that is being developed at Lockheed Martin Aeronautics. In particular, the performance of the various algorithms implemented in the code will be comparatively evaluated on a distributed-memory cluster of multi-core nodes by quantifying the algorithms’ (i) computational costs and (ii) parallel efficiency as the accuracy of the computed RCS is kept constant while the problem difficulty increases.
