The realized performance (error–cost tradeoff) of three computational electromagnetic (CEM) methods, which use parallel algorithms on a supercomputer to predict the radar cross section (RCS) of complex targets, are quantified using the Austin RCS Benchmark Suite. The article demonstrates how modern benchmark suites can be used to evaluate CEM methods empirically and compare their performances objectively.
The Austin RCS Benchmark Suite [1], [2] has recently been populated with 20 carefully selected problem sets that span a wide range in six dimensions of computational difficulty [3].

To a large extent, particle-in-cell (PIC) methods have become the default means of understanding plasma physics. As a result, there are a spate of codes, public and otherwise, that are heavily used. Most of these codes fall under two categories: 1) they largely deal with electrostatic problems or 2) are 1D/2D. As a result, there is a paucity of benchmarking tests that can be used to validate codes and methods that are used to analyze 3D problems. This is especially true when designing methods that seek to break conventional analysis methods, like using unstructured meshes or implicit time-stepping schemes. This review seeks to address this need. We present a number of results that one can use to validate and benchmark 3D electromagnetic finite-element method PIC (EM-FEMPIC) codes for collisionless plasma and beam dynamics systems. Three test cases are presented in significant detail, including beam expansion due to static space-charge expansion, the acceleration of a relativistic bunch by an radio-frequency (RF)-accelerating structure, and benchmarks of accuracy and energy conservation of the particle push. The presented results are compared against either analytical data or those from other codes.

This article describes current initiatives to form benchmarks for the characterization of electronic packages. Four available benchmarks representing typical cases for signal integrity (SI) and power integrity (PI) analysis and varying in complexity from simple microstrip line to a full package model are intended to serve as standardized cases for testing the performance and accuracy of the modeling tools. While the benchmarks, consisting of CAD model files as well as simulated and measured network parameters, are publicly available and described in the accompanying manual, the emphasis in this article is on the description of challenges encountered in creating measured data, the development of modeling capabilities in the computational tools essential for accurate and expedient electromagnetic (EM) analysis of the benchmarks, and common practices going into matching of the simulated to the measured data. Ongoing efforts toward the standardization of densely packed interconnects for die-to-die interfacing on advanced packages, also known as heterogeneous integration (HI), are discussed in the context of the Open Compute Project (OCP). Emerging needs for benchmarking and standardization of test cases and training datasets for machine learning (ML)-assisted characterization of high-speed channels are also outlined.
