Abstract

"Full-wave time-domain algorithms, such as the finite-difference time-domain (FDTD) method, are extensively used in the design of electromagnetic systems. Many systems have become increasingly complex so that it is not possible to run a practical problem on a single-processor computer. Writing and implementing a practical parallel FDTD code that executes on one computer with many processors or many single-processor computers significantly reduces the computation time. This paper discusses the algorithms required for parallelizing an existing FDTD code, EZ-FDTD, using the Message-Passing Interface (MPI) library. The present parallelization of EZ-FDTD breaks a large problem into smaller computational blocks that are spread across several processes in time, memory and space, called spread memory parallel FDTD. In spread memory parallel EZ-FDTD each process node reports their execution times to the server at certain time steps, and based on these reports, the model section boundaries are shifted . Practical engineering problems were simulated for the non-spread memory and the spread memory parallel EZ-FDTD code to determine the difference in performance"--Abstract, page iii.
