The solution of complex electromagnetic (EM) problems requires to address issues related with numerical accuracy and the efficient distribution of the solution procedure over multiple computational nodes. With the advent of multicore processors and high performance computing (HPC) technology, EM software designers need to know how to add new functionality to computational EM codes so that they can run efficiently on these new processors.
This book presents a road map for the analysis of complex material structures using the high-performance parallel simulation software known as HOBBIES (higher order basis based integral equation solver). Focusing on the method of moments (MoM), the book features new parallel programming techniques and a user-friendly code for solving challenging EM radiation and scattering problems. It provides the readers with complete guidance on how to extend the capability of MoM and achieve a faster and more accurate EM analysis and utilize multicore CPUs on desktop computers.
The bottleneck of traditional MoM arises from the lack of memory in computers for solution of large problems. This is mitigated by using higher order basis functions and out-of-core solver in HOBBIES. HOBBIES has the capability to perform numerically accurate EM simulations using thousands of CPU cores in an HPC environment using a properly load balanced out-of-core solver. In this way, it provides a cost-effective choice for addressing modern engineering and scientific challenges that arise from extremely complicated real-life applications.
The book is completed by an academic version of the HOBBIES software.
